Why can’t you increase the throttle when the loader just starts?

After the loader forklift diesel engine has just been started, it should be run at low speed for 3 to 5 minutes. The purpose is:

① Warming up: Let all parts of the machine heat up slowly and evenly to reach normal operating temperature, reduce wear and tear, and avoid mechanical strain;
②Ensure lubrication: When the diesel engine just starts, the viscosity of the lubricating oil is high and the various parts are poorly lubricated. After the engine is warmed up, the lubricating oil gradually reaches each lubricating part to avoid dry friction and damage to the mating surface;
③After the diesel engine has just been started, the machine temperature is low and the diesel combustion is incomplete. At this time, if you increase the throttle and increase the fuel supply, the excess unburned diesel will form carbon deposits, which will intensify the diesel engine emissions. In addition, excess diesel may flow into the crankcase along the cylinder wall, affecting cylinder wall lubrication, diluting the oil in the oil pan, reducing lubrication performance, and shortening the service life of the diesel engine.

For diesel engines equipped with exhaust gas turbochargers, more attention should be paid to warming the car. If you increase the throttle immediately after starting, the turbine speed will increase, and the oil will not have time to reach the surface of each lubricating part, and good lubrication will not be formed. It is easy for the turbine shaft to get stuck, causing failure.
