Auto multi-fuel supply automatic control system and control method thereof

Abstract

The invention relates to the technical field of automobile engine control, provides a full-automatic control system for supplying multiple fuels to automobiles and particularly provides a full-automatic control system and method for supplying multiple fuels to automobiles. The system comprises a signal input part, a signal output part and the like and is characterized in that the signal input partincludes an engine rotating speed signal input end, an oil injection pulse signal input end output by an automobile engine computer, an engine temperature signal input end, a throttle signal input end and the like; the signal output part comprises an engine oil injector pulse signal output end, a PWM duty cycle voltage signal output end and an LED display end; the signal input part is connected to a CPU control unit through an intermediate processing unit, and the CPU control unit is connected to the signal output part through a driving circuit module and provided with control programs in a geometric proportion mode, an automatic mode and a fixed mode separately. The system and method can achieve the positive effects that the environment is protected better and the power is closer to thatof gasoline.

Description

technical field [0001] The invention relates to the technical field of automobile engine control, in particular to a fully automatic control system for multi-fuel supply of automobiles and a control method thereof. Background technique [0002] At present, the development and application of gasoline alternative fuels, such as methanol, methanol gasoline, ethanol, ethanol gasoline, and artificial mixed fuels, is one of the strategic measures taken by the country. But nowadays, the engines of ordinary cars are mostly gasoline engines, which are not compatible with alternative fuels and cannot be used directly. [0003] Patent No. "201110218929.8" invention patent "A vehicle fuel control method and controller", discloses a technology to effectively control the fuel injection amount of the engine through the controller without changing the vehicle computer. But as far as the actual production operation is concerned, it mainly detects the outdoor ambient temperature, and ideal c...

Problems solved by technology

But as far as the actual production operation is concerned, it mainly detects the outdoor ambient temperature, and ideal control can only be achieved when the engine temperature is at normal temperature. After the engine starts running, the engine temperature cannot be detected in real time, and accurate control cannot be guaranteed. , and in the control method, when the outdoor ambient temperature is less than or equal to 10 degrees, the delay control cannot accurately judge the engine temperature at this time, cannot be accurately controlled in real time, wastes fuel, and the combustion is insufficient, so it cannot be implemented in practical applications
