山東裝載機http://www.jmkey.cn/鏟車柴油機剛起動后，應(yīng)低速運轉(zhuǎn)3～5分鐘，其目的是讓機體各部分緩慢、均勻升溫，達(dá)到正常工作溫度，減少磨損，避免機械性拉傷；柴油機剛起動時，潤滑油粘度大，各部件潤滑不良，暖機后使?jié)櫥椭鸩降竭_(dá)各潤滑部位，避免干摩擦，損壞配合表面；柴油機剛起動后，機器溫度低，柴油燃燒不完全。此時，若加大油門，增加供油量，多余的沒燃燒柴油就會形成積炭，使柴油機排放加劇。此外，多余的柴油還可能沿氣缸壁流入曲軸箱，影響氣缸壁潤滑，并會稀釋油底殼的機油，降低潤滑性能，減少柴油機的使用壽命。
After Shandong diesel forklift loader just starting, should low speed for 3 to 5 minutes, and its purpose is to allow each part of the body is slow, uniform temperature reached normal operating temperature, reducing wear and avoid mechanical strain; just starting diesel engine lubrication oil viscosity, poor lubrication of the components, so that after the warm-up and gradually reach the lubrication lubricating parts, to avoid friction, damage the mating surface;diesel engine just after the start, the machine low temperature diesel combustion is incomplete. At this point, if the throttle to increase the amount of oil, the excess will not form coke combustion of diesel, diesel engine emissions increase. In addition, the extra diesel may also flow into the crankcase along the cylinder wall, the impact of the cylinder wall lubrication and will dilute the oil sump, lower lubricity and reduce engine life.

山東裝載機http://www.jmkey.cn/對于裝有廢氣渦輪增壓器的柴油機，更應(yīng)注意暖車。如果起動后立即加大油門，渦輪的轉(zhuǎn)速升高，而機油來不及到達(dá)各潤滑部位表面，形不成良好潤滑，很容易產(chǎn)生渦輪轉(zhuǎn)軸卡死的現(xiàn)象，造成故障。
Shandong loaders equipped for diesel exhaust gas turbocharger, but should pay attention to warm up. If you start to increase immediately after the throttle, the speed of the turbine increases, but arrived too late to the lubrication oil parts of the surface, do not form a well-lubricated, it is prone to the phenomenon of the turbine shaft stuck, causing failure.
