正确预热发动机摩托车冷车启动后,应作短暂的预热运转(尤其是冬季,预热时间要长一些),使缸体温度升高,润滑油进入正常工作状态,如果勉强起步,发动机负荷增大,易使摩托车内部机件加速磨损。有人认为,摩托车启动后直接起步可以省油,其实不然,这样不但不能省油反而费油,因为缸体未达到正常温度,发动机工作不连续,甚至熄火,使燃料不能 The correct preheating motor motorcycle cold start, should make a brief warm-up operation (especially in winter, warm-up time longer), the cylinder temperature, lubricating oil into normal working condition, if barely started, the engine Increased load, easy motorcycle parts accelerated wear and tear. Some people think that the direct start after the start of the motorcycle can fuel-efficient, it is not true, so not only can not fuel but instead oil, because the cylinder did not reach the normal temperature, the engine does not work continuously, or even turn off the fuel can not
