Methods to reduce wear on Petrol Car engine

To reduce wear on Petrol Car engine, it is best to preheat the car in the morning.

After a night of standing, the lubricating oil on the friction surfaces of the Petrol Car engine basically disappears, and the oil film protection is lost; low temperature greatly increases the viscosity of the lubricating oil, and the adhesion and fluidity become worse. At this time, the movement resistance of the Petrol Car engine is greatly increased, and more than 60% of the power at the start is used to overcome the movement resistance. At this time, the problem of vehicle preheating is in front of us.
The cold engine needs to be preheated. According to experts, the wear of Petrol Car engine during cold start accounts for about half of the total wear. Normal idling warm-up can reduce this wear and extend the service life of Petrol Car engine. At low temperatures, metals will show less elasticity and wear resistance; only at working temperature can the Petrol Car engine reach normal matching clearance and maintain the best working condition.
After starting the Petrol Car engine at low temperature, start driving immediately. Due to the uneven mixing ratio, the output power of Changan Car engines is insufficient; at low temperatures, inadequately atomized fuel cannot be fully burned, and carbon deposits are easily formed; some Petrol Car is not atomized, and flows directly from the cylinder wall into the crankcase to mix with the engine oil, reducing the quality of the engine oil.
The longer the warm-up time is, the better. If the engine is warmed up for a long time, the Petrol Car engine will do useless work, waste fuel and be harmful to the environment. Under normal circumstances, it is advisable for low- and medium-end cars to be able to run at normal idle speed, and the water temperature is 70℃~80℃; at normal idle speed, the carburetor Petrol Car engine will idle smoothly after pushing back the choke; the electronic fuel injection Petrol Car engine will drop from 1200 rpm in the fast idle state to 800 rpm, and the driver only needs to see that the tachometer is normal before driving. Not only the Petrol Car engine, but also the gearbox needs to be preheated.
