Homogenous charge compression ignition (HCCI) is a technology for concurrently reducing nitrogen oxides (NOx) and particulate matters (PM) emissions. Since, the pure HCCI lags in control over combustion phasing, Pre-mixed charge compression ignition (PCCI) method is proposed. To achieve partial homogeneity in PCCI combustion, the air is pre-injected with fuel. The main injection is required for the combination to take place. This paper investigates the impact of using the varying percentages and types of bio-diesels for the constant speed genset application engine. The paper first discus the effect of various ratios of diesel and biodiesel mixtures on the performance parameters like engine power, specific fuel consumption (sfc) and the break thermal efficiency. These effects are caused by the combustion happening inside the combustion chamber which can be seen in pressure, temperature and heat release curves. The result of the simulation finally discusses the formation of NOx and PM emissions during the combustion. These results also provide guidelines for actual testing of the engine with bio-diesel.

In this research, the residual gas, peak firing pressure increase, and effective release energy were completely investigated. To obtain this target, the experimental system is installed with a dynamo system and a simulation model was setup. Through combined experimental and simulation methods, the drawbacks of the hardware optimization method were eliminated. The results of the research show that the valve port diameter-bore ratio (VPD/B) has a significant effect on the residual gas, peak firing pressure increase, and effective release energy of a four-stroke spark ignition engine. In this research, the engine was performed at 3000 rpm and full load condition. Following increased IPD/B ratio of 0.3–0.5. The intake port and exhaust port diameter has a contrary effect on engine volumetric efficiency, the residual gas ratio increase 27.3% with larger intake port and decrease 18.6% with larger exhaust port. The engine will perform optimal thermal efficiency when the trapped residual gas fraction ratio is from 13% to 14%. The maximum effective release energy was 0.45 kJ at 0.4 intake port-bore ratio, and 0.451 kJ at 0.35 exhaust port-bore ratio. The NOx emission increases until achieved a maximum value after that decrease even VPD/B was still increasing. With a VPD/B ratio of 0.35 to 0.4, the engine works without the misfiring.

“…4,13 However, it should be noted that the database used for training the ANN is commonly built by the numerical simulation results due to the cost, thus the accuracy of the numerical simulation is critical to the results of ports optimization, so a lot of research work on port simulation has been done by researchers. Table 1 gives the accuracy of the simulation results in the past decade, [30][31][32][33][34][35][36] in which the T-port means tangential port and the H-port means helical port. In the previous work, 30,31 the simulation of intake ports mainly aimed to predict the flow coefficient, and the predicted result of swirl ratio was only used to reflect the changing trends along with the increased valve lifts.…”

In-cylinder flow characteristics, which are mainly determined by the intake ports, have a decisive influence on the mixture formation and combustion process of internal combustion (IC) engines. To develop the optimum intake ports in a four-valve diesel engine, the full-parametric design method coupled with genetic algorithm (GA) and artificial neural network (ANN) was adopted in this study. Different from previous studies, the full-parametric templates for the tangential and helical ports were established. Then, to improve the precision of the CFD result which was used to train the ANN, the near-wall region affected by viscosity was resolved by the “enhanced wall treatment” during the simulation process. Besides, considering the interaction between the outlets of adjacent intake ports in the four-valve engine, the ANN was divided into three parts to better predict the flow performance of the combined intake ports. Finally, the developed intake ports based on ANN and GA were machined to the flow box and validated by the steady flow test. The low deviation of 4.71% in swirl ratio between the design target and the experiment result confirms that this method can be well applied to the development of the intake ports in a four-valve diesel engine.
