only to overcome the friction of the engine’s internal parts itself, does not maintain a minimum output power of the engine speed and stable operation, is one of (economic engine operating conditions of the five basic conditions, large load conditions, the idling condition, accelerating condition, cold sewing condition).

[ 123] experienced owners know, the car in the early morning cold to hot cars, the more cold days, the longer the time you want. So in order to faster, acute people hard to step on the gas, or temporarily increase the idle speed. This can indeed much faster, but this time, because the cylinder block and the cold cylinder wall attached to some of the above diluted gas oil droplets in the cylinder wall, the piston and cylinder wall is formed between the thin film, while too high speed exacerbated friction. At the same time point to note is that the oil is very strong at the time of idling, the fuel atomization is poor, but also promote the formation of larger droplets. Over time, burning oil is only a matter of time.
