If an engine ticks over slowly or too fast an adjustment must be made to the carburettor. 如果发动机空转得太慢或太快,应该调整汽化器。
The explosive mixture of the petrol engine is provided by a carburettor, but in the case of the diesel engine the supply is effected by an injection or jerk pump which forces a shot of fuel into each cylinder in turn according 翻译:汽油发动机由一个化油器输送可燃混合气体,而柴油发动机,由一个喷射泵或柱塞式燃油泵实现燃油供应,此泵根据正确的点火顺序把少量燃油依次压入每个汽缸。
carburettor
[ noun ] mixes air with gasoline vapor prior to explosion <noun.artifact>
Carburetor \Car"bu*ret`or\, Carburettor \Car"bu*ret`tor\, n. 1. (Chem.) An apparatus in which coal gas, hydrogen, or air is passed through or over a volatile hydrocarbon, in order to confer or increase illuminating power. [Written also {carburettor}.]
2. One that carburets; specif., an apparatus in which air or gas is carbureted, as by passing it through a light petroleum oil. The carburetor for a gasoline engine is usually either a {surface carburetor}, or alternatively a {float carburetor} (called also {float-feed carburetor}, or {spray carburetor}). In the former air is charged by being passed over the surface of gasoline. In the latter a fine spray of gasoline is drawn from an atomizing nozzle by a current of air induced by the suction of the engine piston, the supply of gasoline being regulated by a float which actuates a needle valve controlling the outlet of the feed pipe. Alcohol and other volatile inflammable liquids may be used instead of gasoline. [Webster 1913 Suppl.]
