Before starting the tractor, the operator who repeatedly stepped on the accelerator started to simulate the starting action of the driver and repeatedly pressed the accelerator. This is wrong. Before the car started, the driver repeatedly stepped on the accelerator to start working on a carburetor and an acceleration device, so that more gasoline was injected into the cylinder to meet the start-up needs. In this way, the tractor driver does not only have no effect on the start of the tractor, but also increases the wear of the injection pump operating device and the oil amount adjusting mechanism. Many throttles mistakenly assume that the throttle is at its maximum when starting, and more oil is supplied to the cylinder for easier starting. In fact, if you use a large throttle to inject more fuel into the cylinder and the mixture is too concentrated, it is not easy to start. When the big throttle starts and the big throttle starts, it will cause the unit to crash, and it is very easy to damage the transmission parts and farm implements. Therefore, under normal circumstances, when the locomotive has no load, it should be started with a small throttle. When there is a load, it should start with the throttle. During operation and before the flameout, some of the throttlers used the throttle as a horn, sending some kind of signal with the throttle, or slamming a few throttles before the flame was turned off. This is very detrimental to the engine. Because of the continuous change of the engine's high and low speeds, the inertia and load will change drastically. This will cause the crankshaft to continuously change and the inertia and load will change drastically, which will easily cause fatigue damage to crankshaft connecting rod mechanism and valve mechanism. At the same time, the large amount of diesel fuel that enters the cylinder due to the throttled valve cannot fully accumulate and accumulate in the cylinder. The infiltration into the oil pan dilutes the engine oil, resulting in burning of tiles and slicing tiles. Some clutches do not reduce the throttle when the clutch is disengaged. Some operators do not reduce the throttle in time when the clutch is disengaged, causing the engine throttle to idle, causing a sudden increase in the speed. This not only wastes fuel but also aggravates the grinding of the drive train. When the throttle maintenance locomotive is not closed during maintenance, the crankshaft is cranked. If the throttle is not closed at this time, the injector will continue to inject oil into the cylinder. This not only wastes fuel, but also part of the fuel will flow into the oil pan. Dilute the oil to speed up machine wear.
