Modeling and Simulation of Gasoline Engine Speed-governing System

The mechanical speed adjustment device is replaced by the electronic device gradually. The performance of the electronic speed adjustment system will effect the control accuracy directly. If the simulation model of the speed adjustment can be established, it can offer theory gist for developing a good speed-governing system. And the experiments can be reduced ,and the manpower, material resources, financial resources can be saved. Basing of these, the simulation computer model of four stroke gasoline engine is established first according to the four stroke gasoline engine's operational principle in this paper. Then the simulation result and the result contrasting to the experiment are given out and the gasoline engine speed-governing system model is established based on the valve control. And the simulation result is also given out.
