Computer optimization in choosing internal combustion engine and gearbox for given vehicle performance by traction diagram

Reporter: Matijevic D.

Design and construction modern motor vehicles in mass production is based on typified powertrain and joint platform in order to increase the competitiveness and lower product prices. Internal combustion engine and gearbox are adopted for vehicle in development from a range of finished products available in the market.
The paper presents the optimization of selection internal combustion engine and gearbox by traction diagram toward those input parameters of the vehicle dynamics.
During the process, the program performs the comparison between vehicle performance in development with the performance of the selected engine and gearbox obtained through traction diagram.
The optimal choice is obtained according to the given criteria, related to the power and torque of the engine and transmission ratios.
The program displays digital and analog results through tables and graphs.
