“…Conversely, it cannot achieve the effects of optimisation. 35 Therefore, it is particularly important to choose a reasonable optimisation range for the matching parameters. The diesel engine's efficiency, performance and emission indicators are closely related to the heat source and the cold source, while the parameters related to the valve timing and the fuel system determine the high and low temperatures, which affects the piston's thermal load.…”

Optimising the parameters of valve timing and fuel system can promote the applications of high-power diesel engines that have high efficiency and low emissions. Nevertheless, the problem of the piston’s thermal load needs to be considered. In this paper, a calculation model for the working process of a high-power diesel engine and a finite element model of the piston’s thermal load were established. The piston’s thermal boundary conditions were determined and applied to the calculation of the piston’s thermal load, and the key temperature points of the piston were measured using the temperature plug method to verify the correctness of the model. Subsequently, analysis of the patterns of the piston’s thermal load’s evaluation parameters was carried out with the influencing factors based on the valve timing and the fuel system. The sensitivity and the weighting between the evaluation parameters and influencing factors were analysed using the Grey Correlation method. A new method for the comprehensive evaluation index of the piston’s thermal load with the influencing factors was proposed and applied. The research results show that the margin of error of the piston’s thermal load’s model was small, and sensitivity analysis revealed correlation between the influencing factors and the evaluation parameters of the piston’s thermal load, the comprehensive evaluation method could quantitatively analyse the piston’s thermal load.

This paper describes the requirement of the Numerical simulation of compression ignition diesel injection by the use of computer language and it also compares the performance parameter for the biodiesel such as jatropha and karanja. The Engine test was carried out in 512 Army base workshops for the experimental validations. It was carried out on SAJ dynamometer which was installed in Engine test house for testing of Engines. Performance parameters such as Brake power, Brake Torque, Mechanical efficiency, Thermal Efficiency, Pressure vs Crank angle and Heat release Rate vs Crank Angle was taken from the Engine test house. The Program code for the Performance parameter of Engine was developed in C++ language.Then the simulation was carried out. The simulation results were compared and analyzed with the experimental results. The final results was effective for compression ignition diesel injection. As we know that today's world is approaching towards computer simulated results, so the numerically simulated results will save time and money for engine testing house. Likewise we can approach towards numerical simulation for various types of Engines.

Dual-fuel engines are capable of operating using a mixture of two different fuels. Generally, the primary fuel is a gaseous fuel (CNG, LPG, Hydrogen), while diesel is used as a pilot ignition source, i.e. functioning on heat of compression and not a spark plug. There have been a few dual-fuel engine strategies to control the speed of the engine based on varying loads, but these require the addition of complex mechanisms to the existing systems. This paper discloses a methodology for controlling the diesel quantity during dual-fuel operation. According to the engine speed and accelerator pedal position, a gaseous fuel injector in the system injects a predetermined quantity of gaseous fuel. Based on the regulated quantity of gaseous fuel, the intake manifold creates an air-gas fuel mixture. The air-gaseous fuel mixture and a metered quantity of diesel are delivered to the combustion chamber via the intake manifold, fuel injection pump, and other components. The governor and fuel injection pump work together to measure the quantity of diesel according to speed and load conditions. During dual-fuel operation, the governor regulates engine speed by controlling the quantity of diesel delivered to the engine based on speed and load conditions.
