①To achieve the most suitable mixture concentration for the engine under various operating conditions,and to maintain the best power,economy,and emission performance of the engine under various operating conditions. ②It has a deceleration and fuel cut-off function,which not only reduces emissions but also saves fuel. ③When driving in different regions,the engine control unit(ECU)can timely and accurately compensate for changes in air density caused by changes in atmospheric pressure or external environmental temperature. ④During the transitional operation phase of acceleration and deceleration,fuel control can quickly respond,making the car's acceleration and deceleration performance better. ⑤Increased fuel injection pressure,resulting in better atomization effect;Due to the installation of an injector in each cylinder,the fuel distribution in each cylinder is relatively good;Beneficial for improving the stability of engine operation. ⑥In the intake system,due to the absence of a throat like a carburetor,the intake resistance is reduced.In addition,a reasonable design of the intake duct can fully utilize the boosting effect of the intake air inertia,increase the intake volume,improve the engine's output power,and increase power performance. ⑦When the engine is started,the engine control unit can be used to calculate the required fuel supply during startup,and it can smoothly warm up the engine,making it easy to start and improving the warm-up performance. ⑧After the electronic fuel injection system is equipped with an emission control system,it greatly reduces HC Emissions of three harmful gases,Co and No.The electronic fuel injection engine can adapt well to the current requirements for car use,namely reducing emissions,reducing fuel consumption,increasing output power,and improving driving performance. |
