Abstract:

The GDI(Gasoline Direct Injection engine)technology of gasoline engines has important application value to the vehicle power, fuel economy and emission. A set of test systems of constant volume burner is designed by analyzing the problems existing in the current domestic and foreign research.  The key components of the control system of the constant volume burner are introduced，and the design principle of the oil pressure control unit, DC booster unit and time division drive unit is presented.  Simulation results of different inductance and the response of the fuel injector indicate that the designed system can meet the test requirements.

Key words: constant vessel combustion, gasoline direct injection engine, control system
