In winter, the car starts slowly and accelerates slowly. Will slamming on the accelerator affect the car?

It has an impact.

1. After the vehicle is parked for a long time, the oil in the engine will flow back to the bottom of the crankcase under the action of gravity. When the vehicle is just started, due to the poor fluidity of the oil and the oil reaching the parts that need to be lubricated, Time delay;

The engine oil cannot be immediately sent to the places that need lubrication to form a protective oil film on the components, especially the camshaft, which is a high-point position that requires pressure lubrication. At this time, when the engine is running at high speed, many parts will be dry grinding, increasing the wear of various parts.

2. When the vehicle is cold-started, components such as piston rings, pistons and cylinders are still in a shrinking state, and the matching gaps between these components cannot reach the ideal matching value. In addition, the sealing ability of the engine oil is insufficient. Strong, high-speed operation of the engine will cause the exhaust gas in the combustion chamber to enter the crankcase and pollute the engine oil. At the same time, the piston rings cannot scrape off the oil on the cylinder wall, causing oil burning. This is also the reason why many vehicles emit blue smoke during cold starts.

Precautions for using a car in winter:

1. Keep the engine warm

In order to protect the engine in winter, antifreeze must be To choose the right one, antifreeze should be changed every two years, but mixed antifreeze must be changed every year. Then there is the lubricating oil. Winter has higher lubrication requirements for cars. If you use summer engine oil, it must be replaced. Oil that has been used for a long time and is black in color must be replaced in time.

2. Tire maintenance

When the weather is cold, the rubber will become hard and brittle. The tire pressure in winter should not be too high, but it should not be too low. Soft tires will age quickly if used at low pressure. In addition, inclusions in the tire tread should be cleaned frequently in winter, and tires that have been patched more than once should be avoided. In addition, tires that have been used for a long time have different degrees of internal and external wear. To ensure safety and reduce wear, tires should be replaced regularly.
