JAC Ruifeng on startup difficulties

Hello! 1. Battery storage capacity decreases. Cars generally use starter valve regulated lead acid batteries, which are relatively sensitive to temperature, especially older and lower quality batteries. The starters of large-displacement locomotives all belong to the kilowatt class and the instantaneous starting current is greater than 100 amps. They consume huge amounts of power and the voltage drop from poorly performing batteries is very serious. The transistor on the igniter cannot generate enough primary voltage to power the ignition coil, and the spark plug's ability to produce spark is not strong and, of course, it will be difficult to start . 2. Engine oil has poor performance or is incorrectly selected. If the viscosity of the engine oil increases significantly in winter, the internal resistance of the engine will also increase.
