An Investigation on Electronic Control System of XiaLi 2000 Lean Burn Automobile Gasoline Engine |
| |
| Abstract: | The development of an electronic control system suitable for lean burn gasoline engine is introduced.The ECU of the system is in reference to Siemens' demonstrational design.It has C167 series single chip as its microprocesser,and controls the engine in the centralized way.The ECU can function as those of the advanced automobiles.The system is mainly used in lean burn experiment on Toyota 8A16 valve EFI gasoline engine.Experiments show that this lean burn gasoline electronic control system can basically satisfy the requirements of accuracy and speed of control.The fuel consumption and emissions of the engine are improved remarkably.In addition,it has reliable performances,strong resistance to disturbance,perfect function and convenient use. |
