火花塞是发动机上的一个很重要的部件。它的作用是让点火线圈传来的高压跳过其间隙,产生火花,从而点燃混合气。如果火花塞发出的火花不强烈,则对点燃混合气有影响,发动机便不能正常工作。 首先谈一谈火花塞的选用。由于火花塞正常工作时必须保持一定范围的温度,所以就要求火花塞吸热和散热在某一温度范围内保持平衡。如温度过高,易造成因火花塞炽热点火,对火花塞寿命也有不利影响;如果温度过低,火花塞失去自洁能力,易产生积炭,使
The spark plug is a very important part of the engine. Its role is to make the high pressure ignition coil to skip its gap, resulting in sparks, thus igniting the mixture. If the spark plug sparks are not strong, then the impact on the gas mixture, the engine will not work properly. First talk about the choice of spark plug. Because of the normal working hours of the spark plug, a certain range of temperature must be maintained. Therefore, it is required that the spark plug absorbs heat and dissipates heat in a certain temperature range. Such as the temperature is too high, easily lead to hot spark plug ignition, spark plug life also has an adverse effect; if the temperature is too low, spark plug loss of self-cleaning ability, easy to produce coke, so that
