Wuling Light 6400C cool car can't start completely.

Under the condition of low temperature, the main reasons of engine starting difficulty are the increase of lubricating oil viscosity, the deterioration of fuel volatility and the weakening of battery working ability. Lubricating oil has high viscosity and poor fluidity, which increases the rotation resistance of the engine crankshaft, reduces the starting speed, slows down the gas flow rate in the intake pipe, and causes poor fuel atomization and can not be started quickly.
