The objective of this study is to ensure the proper amount of the mixture taken in the cylinder and to improve the efficiency of the two-stroke engine by using variable valve timing.
Ansys Fluent code has been used in numerical analysis. The cylinder pressure and temperature variation have been investigated in different inlet pressures. The inlet pressure has been selected in 20, 40 and 60 kPa and the variable valve duration of inlet valve has been investigated in these inlet pressures. Combustion analysis was performed in three different opening times of inlet valve as 100, 125 and 150 CA ATDC. Closing time of intake valve has been selected as 273 CA ATDC. Ignition time is selected as 20 CA BTDC. Engine performance and CO, CO2 and HC emissions have been investigated in the result. Consequently, the variable valve timing applied to the two-stroke engine will provide fuel efficiency. Due to the fact that this study is innovative and creative system for hybrid vehicles, it will form the basis for Industrial projects and also, will be able to provide both the employment and value-added.
