Abstract

The invention provides an oil injection control system which comprises a throttle valve body, an oil injector, a sensor, an optimizer and a controller. The sensor is arranged on the throttle valve body, is used for detecting location opening of the throttle valve body and generates an airflow or air pressure detection value U1(i) according to a location opening signal of the throttle valve body, the optimizer receives the detection value U1(i) and computes an optimization value U2(i) according to the equation that U2(i)=U1(i)+delta U and the equation that delta U=(K / e^t+K1)*U1(i), and the controller is connected with the optimizer, controls the oil injector so that oil injection quantity of the oil injector is reduced when the delta U is a negative value and the oil injection quantity of the oil injector is increased when the delta U is a positive value. The invention further provides an engine and an oil injection control method. By the aid of the oil injection control system, power of an automobile is increased, an energy conservation effect of the automobile is good, noise is reduced, and an energy conservation performance of the automobile is improved.

Description

technical field [0001] The present invention relates to the technical field of engine design, and more specifically relates to a fuel injection control system. The present invention also relates to a fuel injection control method and an engine with the above fuel injection control system. Background technique [0002] At present, the mechanical throttle assembly for automotive internal combustion engines mainly consists of three parts: throttle body, stepping motor and position sensor. Among them, the function of the position sensor is to detect the opening degree of the valve plate of the main channel of the throttle valve, convert the information of the opening angle of the valve plate into a voltage signal, and input it into the automotive electronic control unit (ECU) for the ECU to judge the function, and the ECU according to the current engine Combined with the voltage signal of the position sensor, the fuel injection quantity required by the current engine is obtained...
