Introduction

Modern land transport modes owe their development mainly to the use of piston internal combustion engines as power plants. It is ICE pistons that are until now the main type of power plants, mainly used on cars, tractors, agricultural, road transport and construction machines. This trend continues today and will continue in the near future.

Course design is the final part of the educational process for the study of discipline, revealing the degree of assimilation of the necessary knowledge, their creative use to solve specific engineering problems. It serves simultaneously as the initial stage of the independent work of a young specialist, reducing the period of its adaptation in production .

Conclusions and conclusions

In operation, the engine of the car is designed with the definition and calculation of the main components. Detailed development of the engine design was carried out. Development includes design and strength checks of all mechanisms. Calculations have shown that all parameters under investigation meet safety requirements and do not exceed permissible parameters. Therefore, it can be concluded that the designed engine is suitable for further research and checks.
