EGR realizes low temperature combustion and reduces heat loss, on the other hand, thermal efficiency decreases by　burning velocity deterioration under heavy EGR operation. T.Alger et al. in SwRI proposed ”Dedicated EGR”(d-EGR) that is running one or more cylinders rich and routing 100% of that cylinder’s exhaust directly into others, and it generates significant amount of CO and H2 that promote burning velocity. This research aims to improve thermal efficiency and inspect fuel ignitability by advancing ignition timing, and clarify the operable conditions of the natural gas SI engine using d-EGR.

Homogeneous Charge Compression Ignition (HCCI) engine has attracted considerable interest as a new combustion concept for internal engines in recent years because of high efficiency and clean combustion. However its operation range is limited by the knocking at high load, which results from an excessive pressure rise rate(PRR). And, exhaust gas recirculation(EGR) is good method to achieve Low Temperature Combustion. The purpose of this study is to investigate the effects of EGR and CH2O addition under constant amount of fuel on PRR . To do so, numerical analysis combustion experiment with rapid compression machine(RCM) were done. The results show that EGR under constant amount of fuel on PRR had an effect on PRR because of increasing heat capacity, and CH2O addition under constant amount of fuel had not an effect on PRR but had an effect on combustion timing.

Steam reforming is an endothermic reaction and needs high-temperature heat source. SOFC can make direct internal reforming possible, since its operation temperature is very high as 973.15 to 1273.15K and it brings out steam reforming inside the fuel cell using exhaust heat. However the direct internal reforming has a problem that the carbon deposition occurs at the anode, and it causes lowering of operating voltage. In this study, we reproduce the microstructure of the SOFC anode theoretically, and find out the condition for the carbon deposition by reproducing steam reforming on the Ni surface using numerical calculation with elementary reactions.

HCCI (Homogeneous Charge Compression Ignition) engine has a problem that knocking occurs by the sharp pressure rising at the time of high IMEP driving. Knocking can be avoided by retarding combustion phasing. But when　the phase was delayed excessively, combustion become unstable.This study is researching the cycle-to-cycle IMEP variation by retarding CA50, using system of Rebreathing EGR and External EGR. Fluctuation of REGR gas temperature and mass is the factor of the IMEP variation. And the reintroduction period of EEGR gas have relation to the cyclical variation.

PCCI engine is expected that can reduce PM and the NOx emissions. Furthermore, a new combustion concept that also reduces hydrocarbon emissions and the combustion noise by split fuel injection is reported. In this paper, we analyzed the influence that split fuel injection in the PCCI engine gave in combustion phase using elementary reaction numerical calculation. In addition, we tried the identification of the chemical species and elementary reactions which became the big factor to affect the heat release. The results show that the ignition timing become earlier so that there is much fuel which reacted during low temperature oxidation reaction period.

A combustion method called Noise Cancelling Spike (NC-Spike) Combustion is able to reduce combustion noise in pre-mixed charge compression ignition (PCCI) with split injection. This NC-Spike Combustion uses interference of the following “spike” of pressure rise (heat release) on the preceding peak of pressure rise. The overall combustion noise was reduced by lowering the maximum frequency component of the noise spectrum. The period of this frequency is two times of the time interval between the two peaks of the pressure rise rate. This maximum load range of conventional PCCI combustion is limited by the combustion noise, since the maximum pressure rise rate increases as the amount of injected fuel increases. In this paper, we investigates feasibility and controllability of the two-peak heat release rate during high temperature heat release by adding fuel in the adiabatic compression process of pre-mixed gas. The results show that the certain fuel addition timing generates the second heat release, and the interval of peak heat release rate could be controlled.

In spark ignition (SI) engines, exhaust gas recirculation (EGR) can realize reducing NOx emissions and heat loss by the low temperature combustion. However, adjusting the high level of EGR is limited because it incurs decrease of degree of constant volume and cut off flame propagation by the low laminar burning velocity. To improve laminar burning velocity with low flame temperature, numerical analysis of dedicated EGR concept SI engine with various EGR rates was carried out for detail understanding the potential of this concept engine in terms of thermal efficiency and amount of NOx emissions. The results show that Dedicated EGR concept SI engine was able to make higher thermal efficiency than the SI engine without EGR and conventional EGR. NOx emissions was reduced by decrease of the flame temperature while the laminar burning velocity was increased without flame temperature rising due to the influence of H2 and CO that were included in EGR gas as intermediates.

Homogeneous Charge Compression Ignition (HCCI) engine has advantages of high thermal efficiency and low emission over the conventional spark ignition engine and compression ignition engine. Although one way to achieve higher loads without knocking in HCCI engine is the combustion phasing retard, it is difficult to control a combustion-phasing since there is no external combustion trigger for controlling ignition like spark ignition and diesel fuel injection. In addition, recent researches show that too much combustion-phasing retard leads to unacceptable cycle-to-cycle variation of pressure rise rate and Indicated Mean Effective Pressure (IMEP). Thus, it is necessary to develop a HCCI combustion control system to control a combustion-phasing at constant phasing in the expansion stroke accurately to get the high load without knocking. This study investigates the HCCI combustion control system and the algorithm as a means of extending the limit of IMEP of HCCI combustion at high load for realize HCCI engine fuelled with Dimethyl Ether. The result from the model in this study nearly matches with that of experiments for all points and shows accurate traces for each input parameters.

Recent researchers point out that the fuel and the oil are mixed on the cylinder liner and then released from it. During the compression stroke the released droplets reach the auto ignition temperature before flame induced by spark ignition propagate to the spots of droplets, and it is called Pre-ignition. When pre-ignition is occurred, sometimes severe pressure happens and damages the engine severely. This work investigates effects of gas inhomogeneity induced by droplets of fuels and oils on the auto ignition timing and temperature in the direct-injection spark ignition (DISI) engine by means of detailed numerical calculation using multi zone model of CHEMKIN-PRO by changing initial temperature and initial equivalence ratio. In order to assume inhomogeneity in the combustion chamber, 16 zones by multiplying 4 types of equivalence ratio and 4 patterns of temperature is used for detailed numerical calculation. In this study used n-heptane that has to low-temperature oxidation (LTO). Consequently, we found that initial in-cylinder gas pressure affects the auto-ignition of air-fuel mixture and there is possibility to lead to cause Pre-ignition.

In Dimethyl Ether(DME) indirect production processes, DME have a reforming process to separate Methanol. DME has a high cetane number and Methanol has a high octane number. Each fuel has a different combustion characteristics and reactivity. So, this paper was investigated on the combustion characteristics of DME and Methanol. Basically, Methanol has an effect of retarding ignition. However, Within 10% of total carbon mole number in DME, Methanol slightly changed the onset timing of Low Temperature Reaction (LTR) with increasing thermal-ignition preparation range. It means that controlling combustion phasing of DME can be possible without eliminated LTR. In case of IMEP(Indicated Mean Effective Pressure), the highest IMEP was shown within 10% of total carbon mole number in DME

This study investigates the EGR effect under the condition of boost pressure on homogeneous charge compression ignition(HCCI) combustion engine using numerical methods. The calculation is carried out using a single-zone model included in CHEMIKN-PRO. The detailed chemical-kinetic mechanisms and thermodynamic parameters for n-heptane, iso-octane and PRF(Primary Reference Fuel) from Lawrence Livermore National Laboratory(LLNL) are used for this study. The results show that the EGR affects the heat release, the amount of heat release decrease. Hence IMEP decrease with EGR ratio increase. The EGR addition under the condition of boost pressure enhanced the autoignition reactivity, the amount of heat release increased. As a result, we confirm that combined EGR and boost pressure incrase the IMEP maintaining the proper PRR.

Object of this study is to realize improving thermal efficiency and emission reduction with low temperature combustion. EGR is a solution to low temperature combustion, however it occurs burning velocity decrease. To prevent this phenomenon, Dedicated EGR was adjusted to SI engine run by natural gas. The entire exhaust gas of a single cylinder operated by the equivalence ratio varied from lean to rich was recirculated to the other cylinders. Due to H2 and CO included in EGR, slowed burning velocity problem was overcome with increasing of degree of constant volume, thus thermal efficiency could be improved.

A simulation study was conducted to examine the transition from SI combustion to HCCI combustion in a two-stroke free piston engine fuelled with propane. Operation of the free piston engine was simulated based on the combination of three mathematical models including a dynamic model, a linear alternator model and a thermodynamic model. The dynamic model included an analysis of the piston motion, based on Newton's second law. The linear alternator model included an analysis of electromagnetic force, which was considered to be a resistance force for the piston motion. The thermodynamic model was used to analysis thermodynamic processes in the engine cycle, including scavenging, compression, combustion, and expansion processes. Therein, the scavenging process was assumed to be a perfect process.

(cont).... Due to the cycle-to-cycle variation, the change of total mass of fuel in cylinder has a big effect on IMEP. After misfire, unburned fuel and intermediates remain in exhaust gas, which is re-breathed as hot EGR gas, and unburned fuel and intermediates are supplied to next cycle. This leads to the total mass of fuel changes cycle-to-cycle. As a result of feedback control, transient performance is realized but high sensitivity of response cannot be achieved under the constant engine speed.

It is investigated of the DME spray characteristics about varied ambient pressure and fuel injection pressure using the common rail fuel injection system when the nozzle holes diameter is varied. The common rail fuel injection system and fuel cooling system is used since DME has compressibility and vaporization in atmospheric temperature. The fuel injection quantity and spray characteristics were measured. The spray was analyzed of spray shape, penetration length, and spray angle at the six nozzle holes. The 2 type injectors were used, the one was 0.166mm diameter the other one was 0.250mm diameter. The ambient pressure which is based on gage pressure was 0MPa, 2.5MPa, and 5MPa. The fuel injection pressure was varied by 5MPa from 35MPa to 70MPa. When using the converted injector, compared to using the common injector, the DME injection quantity was increased 127% but it didn’t have the same heat release. Both of the common and converted injectors had symmetric spray shapes. In case of converted injector, there were asymmetrical spray shapes until 1.2ms, but after 1.2ms the spray shape was symmetrical. Compared with the common and converted injector, the converted injector had shorter penetration length and wider spray angle than the common injector.

Oral presentation (general), Taketora Naiki, Norimasa Iida

One of the numerous ways of overcoming knocking is to deliberately create fuel inhomogeneities within the combustion chamber, since it has proved to lengthen combustion duration and to drastically reduce maximum pressure rise rate (PRR). Thus, the goal of this paper is to investigate in details the reason why the whole combustion duration tends to enlarge, according to the fuel inhomogeneities. To make this analysis, a 4 stroke optically accessible engine provided with two different chemiluminescence measuring systems have been used. The first system is a chemiluminescence intensifier, mostly to investigate the fuel properties, and the second one is a chemiluminescence imaging system, with a high-speed camera rather for close and precise observations.

The gas emission of diesel vehicle consists of mainly N2, CO2, H2O, and additionally, it consists of CO and THC, results in incomplete combustion of fuel, NOx (nitrogen oxide), it results in high temperature combustion in engine, and PM (particulate matter). Of those emissions, NOx accumulated by the roadside results in harmful influence to pedestrian and resident by the roadside. This roadside partial pollution of NOx consists of driver’s operation, engine dynamics, vehicle’s dynamics and road infrastructures. In this research, it was investigated the influence of driver, driver’s operation to the exhaust gas emission of diesel vehicle, and also it was compared between vehicle adopted for new long term regulation and vehicle adopted for long term regulation by on-board measurement system.

Poster presentation, JSAE

Cooled exhaust-gas recirculation (Cooled EGR) is known as the effective way to mitigate knock in HCCI engines, which helps to extend operating range to high-load limits. However, the misfire is caused easily in low-load limits with high CO. Fuel stratification is combined with EGR to compensate those problems. CO2 is used in order to simulate the effects of cooled EGR in numerical analysis. A combination of cooled EGR and fuel stratification shows extended operating ranges to high-load limits. However, high CO is produced in operating point due to the low combustion temperature with significantly low NOx.

Delaying CA50(Crank Angle of 50％ Heat Release ) of the HCCI engine to expansion stroke can lead to high indicated thermal efficiency as well as the avoidance of knocking. However, this method could induce the problem of cycle variability. In this study, the cycle-to-cycle variation of a HCCI engine fueled with DME was investigated. Experimental parameters of each cycle, such as in-cylinder temperature, pressure and gas flow rate, were recorded by fast response system, and analyzed consequently. Moreover, the interdependency between the combustion and the performance parameters were evaluated.

The HCCI engine is a next generation engine, with high efficiency and low emissions. However a rate of pressure rise is a major limitation for high load range. Recently, we are able to reduce the rate of pressure rise using thermal stratification. Nevertheless, this was insufficient to produce high power. Without the higher equivalent ratio, one way to improve the power is to increase the intake boost pressure. It is suggested that the rate of pressure rise is reduced by thermal stratification and the power is increased by boost pressure at the same time. The objective of this work is to understand the characteristics of combustion, knock and emissions for using both thermal stratification and the boost pressure. The calculations are performed by CHEMKIN and modified SENKIN. As a result of increasing the boost pressure, a higher IMEP was attained while the rate of pressure rise increased only slightly in the HCCI with thermal stratification.

Effect of inhomogeneity of combustion chamber has been thought as one of the way to avoid dramatically generating heat in HCCI Combustion. The purpose of this research is to investigate the effect of inhomogeneity, especially thermal stratification, HCCI Combustion fueled with DME, n-Butane, n-Heptane and iso-Octane. Thermal stratification is made in Combustion Chamber of Rapid Compression Machine with pre-mixture by buoyancy effect. The Pre mixture is adiabatic compressed and on that process, in cylinder gas pressure and two-dimensional chemiluminescence images are measured and analyzed.

Oral presentation (general), SAE

The Homogeneous Charge Compression Ignition (HCCI) engine is possible to achieve high thermal efficiency and low emissions. One of the main challenges with HCCI engines is structuring the systems to control combustion phasing, crank angle of 50% heat release (CA50), for keeping high thermal efficiency and avoiding an excessive rate of pressure rise which causes knocking, when operating conditions vary. Though some HCCI combustion control systems, for example Variable Valve Timing System and Variable Compression Ratio System, have been suggested, these control systems are complex and heavy.

The possibility of turbocharging into a natural gas HCCI engine is investigated experimentally and by simulation. Experiments are performed using a four-cylinder naturally aspirated engine equipped with an external supercharger and a butterfly valve for backpressure control to simulate a turbocharger with efficiency of 0.64. Based on the test results, the performance and emission characteristics are studied in detail through numerical one-dimensional cycle simulations. The thermal efficiency can be improved by raising the engine compression ratio and lowering the turbocharging pressure. At engine compression ratio of 21 and turbocharging pressure of l.9 bar, the brake thermal efficiency reaches 0.43，with NOx emissions of only 10 ppm or less.

In the HCCI (Homogeneous Charge Compression Ignition) engine, fuel and air mixture are supplied to the cylinder and occurs auto-ignition resulting from compression. This method can expand the lean flammability limit, realize smoke less combustion and has also potential for realizing low NOx and high efficiency. The optimal ignition timing is demanded to keep high thermal efficiency. The Ignition in the HCCI engine largely depends on the chemical reaction between the fuel and the oxidizer. Physical methods in conventional engines cannot control it, so chemical method is demanded. Combustion duration is kept properly to avoid knocking. In addition, the amount of HC and CO emissions must be reduced. In this study, objectives are to clarify followings by the calculation with detailed chemical reactions and by the experiment with 2-stroke HCCI engine, the chemical reaction mechanism, and HC and CO emission mechanisms. Ignition and combustion mechanism and effect of pre-mixture heterogeneity on ignition and combustion are also clarified by measuring the luminescence at auto-ignition and combustion process by using an optically accessible engine.

Poster presentation, Combustion Institute

The present study focuses on clarifying the auto-ignition and combustion mechanism in HCCI engine, and acquiring the comparable results in numerical calculations with elementary reactions. Chemical luminescences from radicals were measured in single cylinder 4-stroke optical access engine with DME fuel. DME shows multistage heat release with low temperature reaction (LTR) and high temperature reaction (HTR) at compressed rapidly. DME is expected to be alternative fuel, because of low flame temperature and no soot in a reciprocating engine.
Before experimental research, predictions of chemical luminescence intensity were tried by calculated with elementary reactions added chemical luminescence model. After that, in experiment, two dimensional chemical luminescence images under auto-ignition and combustion were obtained by framing camera, and influences of homogeneity of fuel concentration in combustion chamber on auto-ignition and combustion was clarified. Next the luminescence spectrums were measured by spectroscope and luminescence intensity profiles were measured by photo multipliers with band pass filters.

Homogeneous charge compression ignition (HCCI) engine is expected as next generation engine. However, it is difficult to control auto-ignition timing and combustion duration. In this study numerical calculations with elementary reactions were carried out in order to investigate auto-ignition and combustion completion of DME/Air Mixtures in HCCI engine. As a result, it was clarified relation of maximum temperature and combustion efficiency, and emissions And it was also clarified that in case of same combustion efficiency, increase of EGR rate was effective method to keep slow combustion speed.

Homogeneous Charge Compression Ignition (HCCI) engine has a potential as alternative engine because of its high efficiency and ultra low emission in next generation. However, it is difficult to control ignition timing and combustion duration of HCCI engine, because ignition and combustion of HCCI engine largely relay on oxidation process of fuel. So, in this study, a basic research on mechanism of auto-ignition and combustion of homogeneous fuel / air mixtures was done through both experimental study by using a 4 stroke single cylinder HCCI engine and chemical kinetics calculations of elementary reactions with CHEMKIN.

Radical species in premixed flames of gasoline, methanol, and methane are explored using spectroscopic measurements. It was found that major species having strong radical luminescence are OH, CH and C2, for gasoline and methane, and OH and CH for methanol. The correlation between the equivalence ratio and spectrum intensity ratio of two radical species is linear. There is a possibility of predicting the equivalence ratio from the measurement of the radical emission intensities of a flame.

セラミックス遮熱形２ストロークエンジンは,高温燃焼ガスからの熱損失の低減し,排気エネルギの回収し,大幅な熱効率の向上を目指すものである。本研究では燃焼壁の高温化に伴う,燃焼室壁面における瞬時熱流束の測定を試みた。厚さ４ミクロンの薄膜形熱電対を開発,セラミックス遮熱形エンジンに装着し,燃焼室表面温度の１サイクル間の履歴を計測記録した。表面温度の時系列データをフーリエ解析し,瞬時熱流束値を算出した。その結果,壁面の高温化に伴い熱損失のサイクル積算値は減少するが,瞬時熱流束の正負のスウィング値は増加することを見いだした。特に６５０Ｋ以上になると,消炎層の破壊が生じ,瞬時熱流束の振幅が極端に増加する。壁面の高温化は排気中のホルムアルデヒドの低減する効果がある。しかし,熱流束振幅の増加は機関のサイクル効率を低下させるので,壁面温度に最適値が存在する。
