A review on development of a lab scaled hybrid vehicle system for small gasoline engine

摘要

It is important to study the vehicle efficiency in order to have better performance and lower emissions.The sub-compact vehicle is powered by an internal combustion engine(ICE).Usually,the incomplete combustion in ICE gives out by-products of such earbon dioxide(CO2),nitrogen oxides(NOx),unburned hydrocarbon(UHC),and water(H2O).The electricity seems can solve the global warming issues contribute by the emission produce from the IC engine by reducing the dependence on the operating system from it.Electric vehicle via an electric motor(EM)give high efficiency compared to internal combustion engine but lower at average top speed.This paper will discuss more on developing the hybrid electric vehicle system,especially for the small gasoline engine.The process involves in the development of the small hybrid system is similar to other larger hybrid vchicle system.However,the system is more compact in size and no external gearing system or gearbox system.When developing this type of hybrid system,the drivetrain structure and the hybrid operating control system configuration is the main attention to be studied.Before developing the hybrid system,it is important to understand the basic component contains in a hybrid system,type of a hybrid electric vehicle,the hybrid drivetrain structure and the hybrid operating control to the environmental effect design and the operating control system that suitable to implement on the small hybrid vehicle.Small gasoline engine in this paper refers to the single cylinderinternal combustion engine with capacity below 150cc.
