Fuel Consumption And Emissions

In order to reduce the fuel consumption and emissions of automobile, the engine idle speed control method was studied. The basic concept of engine idle speed and the requirements and strategies of idle speed control were introduced, and the features and structures of CAN bus technology were analyzed. An idle speed control system of automobile engine based on CAN bus was designed which included main control module, front control module and rear control module. The overall structure, hardware design and software implementation of the system were given. The system can realize the desired functions, and it has certain application value.

Gdi Engines

The gasoline direct injection (GDI) engine is a highly non-linear and a delayed system. The engine modle with time-delays is derived. The delays consist of an intake to torque production state delay and a network -induced interval delay. Base on the Liapunov-Krasovskii function, the criterion of interval delay control system is proposed, which ensure the idle speed control system is stability as well as robust. The simulation results show that the H∞ control has good robustness,which improves the stability of the idle speed of the GDI engine.
