Investigation of torque and power output of power generation system in hybrid electric vehicles with parallel arrangement in driving modes

Nowadays, one of the main points considered by the world’s leading automakers in the design phase, the manufacturing phase and mass production, is the reduction or control of pollutions and emissions in the internal combustion engines of automobiles. Due to the standards set in different countries and recent decades regarding the control of environmental pollution of vehicles, these points are considered by car manufacturers. Because of that, the production of electric and hybrid cars with different designs is slowly expanding over time in the manufacturing lines of vehicles. One of the features of hybrid electric vehicles is the increase in power and torque in the power production system in the parallel arrangement. Therefore, for this group of cars, a smaller internal combustion engine can be considered, which ultimately reduces the emissions, and at the same time, the parallel activity of the two internal combustion engines and AC motor creates the required torque and power in different driving mode. The formation and arrangement of two power sources in this article will be considered parallel. In this paper, we will simulate the movements of pistons in the EF7 national internal combustion engine with a crank and slider mechanism, and the results related to the power and torque produced in the crankshaft of this engine will be drawn and simulated in MATLAB software. BRUSA HSM1 AC motor, which is considered in this paper as the main power source of power and torque generation system, will be analyzed using numerical calculations, as well as information extracted from the catalog of this motor. Finally, by analyzing different driving modes and applying coefficients and efficiencies, torque and power output in these situations are examined.
