The engine is the power source of the car and is known as the "heart of the car". Naturally, it is also the most important component of the car. Since it is the "heart", it is necessary to protect it. So what behaviors do we have in daily use that are more harmful to the engine?Let's talk about that. The first is that maintenance is not carried out on time.
When our car owner buys a new car, the 4S shop will give us a maintenance manual. The maintenance manual will clearly indicate the service time, service date and items that need to be serviced. In daily life, we only need to carry out maintenance on time according to the requirements of the maintenance manual.
But generally speaking, the maintenance interval for mineral engine oil is 5000 km or 6 months, the service interval for semi-synthetic engine oil is 7500 km or 6 months, and the service interval for fully synthetic engine oil is 10000 km or 6 months. Among them, for those owners who drive less than 5000 kilometers per year, we can choose to change the oil once a year.
However, the oil level needs to be checked quarterly to see if there is a shortage of oil. The car has not been driven for a long time, and many times, the car is damaged not by driving, but by damage. Some people can't get 2,000 kilometers a year. Basically, they are always parked or driven over short distances. This is the simplest case.
This leads to battery wear and increased engine carbon build-up. For car owners who use their cars very infrequently, maintenance and use of the car is simply a burden!The car takes a long time to start cold and warm up. As long as winter comes, we often see many car owners in the community start the car and then idle to warm up the car. They usually warm up the car for about 10 minutes.
They believe that this avoids engine wear and tear caused by cold starts. Actually, it is correct to warm up the car. 80% of engine wear is caused by cold driving. But heating a car for a long time can also cause damage to the engine. During the cold start of the engine, the oil cannot fully adhere to the various parts of the engine due to the high viscosity of the oil.
In particular, there is less adhesion to the cylinder walls. If the engine runs at high speed just after starting, it is easy to cause engine wear. This results in increased engine noise and reduced power. It is only when the engine idles for about a minute and the internal temperature of the engine rises that the oil can fully adhere to all parts of the engine.
In this case, the engine oil has the best lubricity and the engine runs to a minimum. The car will not be damaged while driving. The engine works for a long time without affecting its service life. Otherwise, it is often left behind without running. Frequent cold starts of vehicles are the most harmful behavior to the engine.
Warming up for a minute is to protect the engine, but warming up for a long time can damage the engine. The engine runs at high speed and high load fatigue for a long time. We learned here that high speed and high load are not the same thing. Driving at high speeds and low gears also hurts the engine a lot and also increases fuel consumption.
Prolonged high-speed operation causes the engine to always run at full speed, increasing the number of times engine components are running. The parts have a service life, so there is no need to drive at high speed for a long time during normal driving. Friends who drive automatic transmissions, remember to release the accelerator pedal in time to let the transmission automatically shift to the appropriate gear.
Friends who open manual transmissions should change gears in time based on experience. High load operation is also very harmful to the engine. Many times, if the load on the car is too large, it will be very difficult to drive and the engine will run at a high load. Most likely, there was oil on the floor, and the engine rev was only two or three thousand rpm. In this case, the load on the engine is very high.
To sum up, the above are some of the behaviors that damage the engine that are common in our daily use. Everyone must try to avoid them when using the car. Although today's cars are not as refined as everyone thinks, if they are not used correctly for a long time, the life of the engine will also be shortened.
