Problems solved by technology

At this time, due to the low temperature in the cylinder, the fuel combustion is not sufficient, thus greatly increasing the fuel consumption, and at the same time, the exhaust gas will contain more pollutants such as carbon monoxide, hydrocarbons and inhalable particles.

Abstract

The invention provides a throttle control method, system and vehicle for a dual fuel engine. The method comprises steps of detecting the engine water temperature and the oil temperature, further judging whether the vehicle is at a sliding state if the engine water temperature is greater than the first predetermined temperature and the oil temperature is greater than the second predetermined temperature, opening a throttle valve if the vehicle is t the sliding state, and closing the throttle control when opening time reaches the opening time. The throttle control method can reduce fuel consumption, while reducing exhaust emissions.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a throttle control method, system and vehicle of a dual-fuel engine. Background technique [0002] Dual-fuel engines, such as gasoline and diesel dual-fuel engines, have the advantage of low exhaust pollutant emissions compared to traditional diesel engines, and have the advantage of high fuel economy compared to traditional gasoline engines. However, the dual-fuel engine has higher requirements for the temperature in the cylinder. When the temperature in the cylinder is low, the fuel cannot be completely combusted. [0003] In an engine, the intake of air and recirculated gases is usually controlled by a throttle valve. Generally, in a diesel engine, the throttle valve is usually opened and only closed at a certain angle when it is necessary to increase the exhaust gas recirculation rate. In a dual-fuel engine, if the throttle control method is the same as that of a diesel...
