Usually, if the dashboard self-checks before starting the car, if the battery light turns on and it is obvious that the dashboard brightness has reached brightness Normally, the battery is running out of power or has reached the end of its life. Sometimes the instrument can't see it, but when starting the car, you can clearly feel that the starter is turning very slowly. This is also proof that the battery is not working. At that time, the best solution is to find someone to start the car. .
If the starter sounds normally after pressing the ignition button and there is no obvious dimming of the screen or indicator light in the car, it means that the There is no problem with the battery or the starter. If you are unable to light the fire at this time, there may be a problem with the high pressure oil pump or the on-board computer and the mengine does not supply oil. Therefore, this situation usually cannot be resolved by yourself and on your own. can only call a tow truck for rescue.

Notes:
Each sport The The frictional resistance torque of a part, from static to dynamic, largely depends on the viscosity of the lubricating oil. When starting, due to the low engine temperature and high viscosity of the lubricating oil, the resistance torque is also large. In the starting device, an auxiliary starting device is installed to reduce other resistances during starting, so that the friction resistance accounts for the majority of the total starting resistance.
The resistance of drive accessories such as the power required to drive fuel injection pumps, water pumps,s oil pumps, fans, etc. Since the rotational speed is low at start-up, this part of the resistance is much smaller than when the motor is operating normally.
The inertial resistance of a moving part when accelerating from static to a certain speed is approximately 1/10 of the total resistance. Due to the high compression ratio and other reasons, the starting resistance of diesel engines is higher than that of gasoline engines, and the power required for starting is about 3-4 times that of gasoline engines.
