Methanol range extender starting method and device, vehicle and computer storage medium

The invention discloses a starting method and device of a methanol range extender, a vehicle and a computer storage medium, and the method comprises the steps that when the vehicle provided with the methanol range extender detects a starting instruction for the methanol range extender, water temperature data of a vehicle engine are obtained; the rotating speed rising slope is determined according to the water temperature data, and the vehicle generator is controlled to increase the rotating speed according to the rotating speed rising slope so as to drag the vehicle engine to increase the rotating speed; and when the rotating speed of the vehicle engine is increased to the preset minimum rotating speed, controlling the vehicle engine to inject oil and ignite so as to start the methanol range extender. According to the technical scheme, on the premise of adapting to methanol fuel characteristics and gas inlet channel oil injection characteristics and ensuring normal starting of the methanol range extender, oil
