AI Technical Summary

Technical Problem

The existing fuel supply system is highly dependent on gasoline, which limits the development of methanol fuel vehicles, especially due to the insufficient atomization ability of methanol fuel during cold starts.

Method used

A preheating unit is used to preheat the fuel, which improves the evaporation and atomization of methanol. The controller adjusts the throttle opening according to the engine coolant temperature and speed to ensure that methanol fuel can start smoothly in cold conditions.

Benefits of technology

It improves the cold start success rate of methanol-fueled vehicles, reduces dependence on gasoline, and enhances the competitiveness of methanol-fueled vehicles.

Abstract

The application provides a fuel supply control system, a vehicle and a fuel supply control method. The system comprises a controller and a preheating unit. The controller is configured to receive an engine starting instruction, and collect a first water temperature and a first rotating speed of the engine. When the first water temperature is less than a first preset temperature and the first rotating speed is less than a preset rotating speed, the controller controls the preheating unit to preheat fuel, and controls the throttle opening degree to be a preset value. The fuel supply control system can reduce the dependence on gasoline, and improve the availability of a methanol fuel vehicle.
