“…In order to meet the development requirements of this kind of diesel engine, its fuel injection system must be improved according to the needs of diesel engines. The restriction conditions for the improved design of this kind of fuel injection system are as follows [13][14]: (1) The installation and connection dimensions of fuel injection pump are generally not allowed to be changed; (2) The starting point of fuel injection pump cannot be changed; (3) The inner cavity size of the transmission device (guide piston or lead cylinder hole) cannot be changed; (4) Generally, the overall height of the fuel injection pump cannot be changed. In view of the above constraints, in order to meet the needs of power increase and injection pressure increase, the following three ways are generally adopted: (1) increasing the plunger diameter; (2) increasing the cam lift; (3) Increase the plunger diameter and cam lift.…”

Most models of low-power off-road diesel engines in China are single-cylinder diesel engines. The production, use and export of single-cylinder diesel engines are one of the characteristics of internal combustion engine industry in China. As the emission standards of off-road diesel engines are becoming stricter in China, it is of academic significance and engineering application value to study the low emission mechanism and optimization of low emission technical scheme of single-cylinder diesel engines. The purpose of this paper is to study the optimal design of injection pump cam of single cylinder direct injection diesel engine combined with artificial intelligence algorithm. The problems existing in the fuel injection system of domestic large bore single cylinder diesel engine are analyzed. The measures to improve the injection pressure of single cylinder engine are put forward. The basic principle and method of oil pump cam design are given. The artificial intelligence technology is used to simulate and model the new oil pump cam. According to the calculation, the cam design of single-cylinder engine fuel injection pump has its own characteristics. In the design, not only the general technology of the cam design of fuel injection pump, but also the special requirements of the installation and adjustment of single-cylinder engine should be considered to meet the needs of the overall layout of diesel engine. Based on the optimization scheme, the influence of key parameters changes on diesel engine emissions in the simulated production process is studied. The calculation results show that in order to ensure the effective control of emissions, performance and production consistency, it is necessary to reduce the change range of key parameters in the production process. The calculation and analysis show that the fuel supply advance angle, compression clearance and injector extension height are controlled within ±0.5°CA, ±0.08mm and ±0.1mm respectively. The increase percentage of NOx emission is within 9.8%, and the increase percentage of Soot emission is within 8.4%. The calculation results can guide the control of parameters and dimensional tolerance of parts in diesel engine production.

“…for the purpose of heat dissipation in engineering, the high-power power electronics are generally installed directly on the heat sink, and the heat is transferred from the substrate and the heat-conducting silicone grease to the heat sink and then taken away by the cooling medium. the influence of radiation on heat dissipation in this process can be ignored, and thus the main heat dissipation methods are Heat conduction and thermal convection [9][10].…”

With the emphasis on renewable energy and environmental protection, new energy vehicles are gradually entering the social space and electric vehicles are once again moving to new heights. The aim of this paper is to investigate the design of a cooling system for a purely electric bus incorporating computational fluid dynamics. This paper follows the principle of "determine the heat source distribution of the prototype -calculate the temperature rise of the prototype -design an optimised cooling structure -analyse the cooling effect -propose the design of the prototype cooling structure". This paper studies the temperature rise and cooling of the prototype, focusing on the effect of different cooling structures on the temperature rise of the prototype. Based on the heat transfer, a finite element model of the engine is established and the losses and heat source distribution of the prototype are calculated by combining empirical equations and MAP diagrams of the engine losses. The heat transfer process of the engine is investigated, including the heat transfer process within and between the components of the prototype in contact with each other, and the convective heat transfer process between the prototype and the fluid contact surface. Based on the CFD (Computational Fluid Dynamics) method, the flow and temperature fields of the physical air-cooled prototype are calculated using the existing CFD mathematical model, and the influence of the flow field of the prototype heat exchanger ventilation duct on the engine temperature rise is analysed. A forced air cooling solution for the prototype was proposed to determine the structure of the vents, the location of the ventilation holes and the size of the cooling fan. The effect of forced air cooling on the temperature rise of the prototype is compared with the effect of natural air cooling. A parallel water jacket should be designed and its structure optimised in order to compare the effect of the water jacket on the temperature rise of the prototype before and after optimisation. Finally, all studies are combined to provide reference recommendations for the design of the prototype cooling structure.
