What is the reason why the cold car starts to accelerate in the morning?

The reasons for the weak start-up and acceleration of the cold car in the morning are as follows:

1, insufficient oil lubrication

After the vehicle is parked for a long time, the oil will flow back to the bottom of the fuel tank. At the beginning of the vehicle, due to the high viscosity and poor fluidity of the engine oil, it is impossible to flow to all parts of the engine in a short time, so the speed increase will be slower.

2. The standard value of the component is not enough

When the engine is cold-started, the spark plug and other components are still in the contraction state. Because of the cold weather, the gap between these components is difficult to return to the standard value in a short time, so the speed increase in winter will be slower.

The correct way to warm the car when starting the cold car in winter morning.

The correct way to warm up the car in winter morning is to start at 1 minute 30 seconds after the vehicle starts, but don't drive at high speed at this time, but keep driving at low speed. The engine speed should not exceed 3000 rpm, and it should generally be kept at 2000 rpm, otherwise the severe wear and tear suffered by the engine and gearbox will be irreparable. After the engine temperature rises to the normal operating temperature, normal driving can be resumed.
