1.起动前反复踩油门有的机手在起动拖拉机时模仿汽车驾驶员的启动动作,反复踩几下油门,这是错误的。汽车在启动前,驾驶员反复踩油门,是为了让汽化器和加速装置工作,从而多往气缸内喷入一些汽油,以满足启动的需要。而拖拉机所需的燃油是靠喷油泵、喷油器来供给的,启动前无论怎样反复踩油门,也不能使柴油进入气缸,对拖拉机启动无济于事,反而增加了喷油泵操纵装置和油量调节机构的磨损。2.启动时将油门置于最大位置许多机手误认为油门最大,向气缸内多供油便于启动。其实用大油门,喷入气缸内的燃油积聚过多,混合气过浓,反而不
1. Repeatedly before starting the accelerator pedal Some hands to start the tractor to imitate the car driver’s start action, repeatedly stepped on the accelerator, it is wrong. Before starting the car, the driver stepped on the accelerator repeatedly to allow the carburetor and accelerator to work, so that more gasoline was injected into the cylinder to meet the start-up needs. The tractor fuel is required by the fuel injection pump, fuel injector to provide, no matter how the start before the start step on the accelerator, diesel can not enter the cylinder, the tractor does not help, but increased the fuel pump control device and the fuel volume adjustment mechanism Wear and tear. 2. Start the throttle will be placed in the maximum position Many of the crew mistakenly believe that the throttle to the cylinder more fuel for easy start. In fact, with a large throttle, injected into the cylinder fuel accumulation too much, the mixture too thick, but not
