发动机起动时,要用中小油门。当气温在15℃以上时,用小油门起动;当气温在15℃以下时,应先摇转曲轴数圈,再用中油门起动。若一开始就使用最大油门起动,会使进入气缸的燃油过多,混合气过浓而造成发动机被“淹死”,这样不但起动困难,而且多耗燃油。如果用大油门数次起动不了,应关闭油门再起动,待排 Engine start, use a small throttle. When the temperature is above 15 ℃, start with a small throttle; when the temperature is below 15 ℃, crank the crankshaft should be a few laps, and then start the throttle. If you start with the maximum throttle start, will lead to excessive fuel into the cylinder, the mixture is too thick and cause the engine to be “drowned”, so not only difficult to start, and more fuel consumption. If you can not start a large throttle several times, you should turn off the throttle and then to row
