有些摩托车爱好者同时还是汽车驾驶员,他们常常会问起这样的问题:都是四冲程发动机,为什么摩托车更换机油的里程这样短?下面谈一谈对这个问题的看法。 这是因为:虽然四冲程摩托车和汽车都是四冲程发动机,但是发动机的工作温度却大不相同,风冷机的工作温度比水冷机高得多,因此风冷机的油温也高,其失效期就短,这是其一;其二是摩托车发动机的标定曲轴转速一般比汽车发动机高30％～100％,因此要求机油有更高的清洁程度;其三,
Some motorcycle enthusiasts are also car drivers. They often ask such questions as: Are all four-stroke engines, why the motorcycle’s mileage is so short? Now let’s talk about this issue. This is because: although four-stroke motorcycles and cars are four-stroke engines, but the working temperature of the engine is very different, the operating temperature of the air-cooled machine is much higher than the water-cooled machine, so the air-cooled machine oil temperature is high, Its expiration date is short, this is one; the second is the motorcycle engine calibration crankshaft speed generally higher than the car engine 30% to 100%, thus requiring a higher degree of oil cleanliness; Third,
