Development of Hybrid Drivetain

Abstract

Conventional ICE vehicles, while operating in urban settings, perform at very low efficiency due to inherent power characteristics Hybrid vehicles have been developed successfully to improve the engine efficiency characteristics, fuel consumption and emission characteristics of the vehicle. Suzuki Bolan is a very common Multi-purpose Vehicle (MPV) used in Pakistan widely for various transport operations. It has a drive cycle corresponding to a very low-efficiency operation. An ICE to Hybrid conversion of the drivetrain of Suzuki Bolan has been presented in this thesis. The process includes the study of already existing characteristics of the vehicle and its drivetrain, calculations, and simulations of various parameters for the optimization of the vehicle efficiency in terms of fuel consumption and emission characteristics. A major part of the study consists of the development of a gearbox, which is a crucial and central component of the drivetrain system. Various parameters of the gears used have been calculated and optimized through the process of simulations. The final model represents a drivetrain that increases the fuel efficiency of the vehicle by a good percentage.
