Abstract

The invention relates to the field of new energy vehicles, and discloses an automotive dual-fuel co-combustion method and a control system. The co-combustion of gasoline and alternative fuels in an injection cycle of an engine fuel can be realized according to the rotating speed of an engine. Meanwhile, the invention discloses an automotive dual-fuel control system, which comprises a controller, a mode selection switch and a sensor, wherein the mode selection switch and the sensor are electrically connected by a cable, and a driver uses the mode selection switch to select the current mode of operation; and a gasoline mode and an alternative fuel mode can be selected, and when an automobile operates in the alternative fuel mode, the controller can control an automobile engine fuel nozzle to respectively inject the gasoline and the alternative fuel for a period of time in an injection cycle. The gasoline and the alternative fuels can be commonly used, so that the problem that the power is insufficient under the situation that the load is larger when the alternative fuel is used is solved.

Description

technical field [0001] The invention relates to the field of new energy automobiles, and more specifically relates to a dual-fuel mixed combustion method and control system for automobiles. Background technique [0002] Under the circumstances of the current energy crisis and increasingly severe environmental pollution, new energy vehicles emerge as the times require, among which the vehicles that can use two or more fuels are the focus of development, and dual-fuel vehicles are equipped with controllers to use It depends on the type of fuel used by the car, such as gasoline or alternative fuels as the fuel for the engine. However, in the actual operation of dual-fuel vehicles, due to the low combustion calorific value of some alternative fuels, if the load is large, the vehicle will When medium engines use alternative fuels, power shortages often occur. Existing dual-fuel control systems can switch between gasoline and alternative fuels, but they cannot solve the problem of...
