To this problem above all we want to be clear about, "Accumulate carbon " how to form:
The benzine that accumulates the input when carbon works as a result of engine namely became much and air is little, and it is low that no matter rotate speed is returned high,in divide evenly fast cruise condition falls, the air that can keep ideal is lighted than, light for nothing than constant no matter rotate speed is much lower not easy generation accumulates carbon, want speed to calculate you quite only 1500 turn run high speed also does not have a thing.
And the air that keeps ideal is lighted than, consider cruise of low rotate speed same also to won't arise to accumulate carbon redundantly, the itself of rotate speed discretion has nothing to do with the generation that accumulate carbon, but only a kind of case can appear into tolerance insufficient and the state that fuel injection quantity adds, . Ran high speed of 120 basic it is to want to run for long, if run for long, engine temperature will be enough burn benzine adequately.
The reason that accumulate carbon is problem of engine high rotate speed not just, the key still is the temperature problem of engine. Cooling fluid temperature wants stability to be controlled in 90 degrees, because the combustion efficiency in the engine below this temperature is best,be, easy inside inlet casing of in season of the gasoline below such temperature condition aerification burns, avoid generation to accumulate carbon so.
If high speed is played below cold car condition, answer easily into what enrage manifold eject baked wheaten cake goes back or combustion arises not completely accumulate carbon, so a lot of cars have over the manifold that take energy of life black the part that accumulate carbon is this reason.
The stability after short time heats up a car drives, fasten urgent step on the gas not to play high rotate speed, won't form bigotry generally speaking accumulate carbon.
Drive daily two kinds of condition that should distinguish a car " quickly " with " cruise " , the word of cruise no matter rotate speed has many low, but can maintain the sky in ideal to light into tolerance and fuel injection quantity than, want to be lighted in ideal sky only than falling, can arise scarcely accumulate carbon.
Summary: Accumulating the reason that carbon forms is engine the benzine in working process became much air is little, the air that should keep ideal only is lighted than, light for nothing than constant no matter rotate speed is much lower not easy generation accumulates carbon, when quickening, rotate speed pulls Gao Keran oil to burn ungodliness, become naturally accumulate carbon, think little generation accumulates carbon to want to rely on rotate speed not simply, more important is divide evenly fast drive, do not give oil often.
