Abstract

The invention provides a fuel supply method, device and system for a methanol engine. The fuel supply method comprises the steps that firstly, the cooling liquid temperature of the methanol engine is obtained when the methanol engine operates; then, according to the temperature of the cooling liquid, the fuel injection mode of the methanol engine is determined; and then, a fuel injector corresponding to the methanol engine is controlled, and fuel of the type corresponding to the fuel injection mode is injected to the methanol engine. Through the mode, the type of the fuel injected to the methanol engine can be determined according to the temperature of the cooling liquid of the methanol engine, so that the fuel combustion quality of the methanol engine is improved, and the heat efficiency of the methanol engine is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a fuel supply method, device and system for a methanol engine. Background technique [0002] The engine is an important component of a car. In recent years, in order to get rid of the dependence on fossil fuels, methanol engines have gradually become a research hotspot in the field of new energy vehicles. Methanol engines use methanol as the main fuel, which has the advantages of clean emission and good economic performance. [0003] However, due to the properties of methanol with large latent heat of vaporization and poor atomization effect, the fuel may not be fully combusted under some working conditions, resulting in poor fuel combustion quality of methanol engines, which in turn reduces the thermal efficiency of methanol engines. SUMMARY OF THE INVENTION [0004] The present application provides a fuel supply method, device and system for a methanol engine to solve the t...
