In situ parking does not turn off the air conditioning, the car idle open air conditioning injury car
Idle car open air conditioning does not hurt the car, the car idle open air conditioning need to worry about water temperature, especially the engine is the use of mechanical fan of the old car. Mechanical fan is driven by the engine crankshaft, in idle, the speed of the engine crankshaft will be slower, so the cooling fan will also turn slower, long idle, insufficient heat dissipation of the engine will lead to high water temperature.
Influence of idling on air conditioning
1. Fuel consumption: the car needs to consume fuel at idle speed. The air conditioning engine needs to drive the compressor, which will undoubtedly increase fuel consumption;
2, shorten the life of the battery: the air conditioning blower is driven by battery power supply, the car in idle, the charging efficiency of the battery is relatively low, the operation of the blower may lead to battery loss, a long time will shorten the life of the battery.
Idle open air conditioning will accumulate carbon?
You know, as long as the engine runs, the car will produce carbon, carbon is not idle when the air conditioning will form. In fact, in the idle state of air conditioning, the degree of carbon accumulation is very light, the car in idle state and uniform speed is similar, compared with the acceleration and deceleration of the car when driving, the carbon accumulation is much less.
In addition, it is true that less carbon accumulates when the car stalls while waiting for a passenger, since the car is not running and therefore does not accumulate carbon. But if the car is cold start soon, the engine has not reached the standard operating temperature, it is best to keep idle state. Because the engine has not yet reached the standard operating temperature, the fuel pump is usually delayed for a while. After the car is turned off, the gasoline injected into the engine does not burn. As the gasoline evaporates, the remaining impurities form carbon deposits.
