Abstract

The invention provides a control method of a dual-fuel engine. The control method comprises the steps of detecting whether the left gasoline amount and the left diesel amount are sufficient; judging whether a discharge lowest mode instruction or a power optimal mode instruction is received or not if the left gasoline amount and the left diesel amount are sufficient; judging whether the price different of gasoline and diesel is higher than a first threshold value or not if the left gasoline amount and the left diesel amount are not sufficient; further controlling the engine to adjust the consumption ratio of the gasoline to the diesel according to the price different of the gasoline and the diesel so as to reduce the running cost of the engine if the price different of gasoline and diesel is higher than the first threshold value, and controlling and running the engine in a normal working mode if the price different of gasoline and diesel is not higher than the first threshold value. A vehicle applying the control method has the advantages of being low in energy consumption and low in running cost. The invention further provides a control system of the dual-fuel engine and the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dual-fuel engine control method, system and vehicle. Background technique [0002] Internal combustion engine, as the power source of mobile devices such as automobiles, locomotives, ships, agricultural machinery (agricultural vehicles), construction machinery and military vehicles, is an indispensable core component of mobile devices, and it mainly consumes oil. Therefore, how to reduce the energy consumption of the internal combustion engine and reduce the operating cost of the internal combustion engine is particularly important. [0003] In addition, the internal combustion engine is also a major pollution source of the atmospheric environment, especially the urban atmospheric environment. In order to reduce the emission of pollutants, exhaust gas purification equipment can be used to treat the exhaust gas. This method can reduce the amount of pollutants emitted by veh...
