1. Before starting: Check the oil surface of the oil pan before checking to ensure that the oil is sufficient and ensure lubrication. If not, add it to the position specified by the oil gauge. Check the coolant in the tank for proper cooling. Check the air and diesel filter water draining the fuel line. Check the mailbox, if not enough, add fuel. Check the electrical system (whether the connection lines, switch wiring, etc. are solid and reliable, the battery electrolyte is sufficient, if not enough, add enough electrolyte), check the belt, the tightness should be adapted, the belt is too loose to slip the water pump, the fan is not working properly, The cooling effect is poor, the engine water temperature is high, and over-tightening results in excessive force on the pulley shaft and shortens the belt life. Check the car chassis and controls to prevent the car from driving sick.
2. Startup: Start the diesel engine before starting the work and confirm that it meets the requirements before starting the diesel engine (when the winter weather is cold, the diesel engine must be warmed up before starting). When starting the diesel engine, the continuous startup time cannot exceed 10 seconds. The time must not be less than 1 minute. If it fails to start for three consecutive times, you should check the cause, troubleshoot, and start again. Check after startup. Oil pressure: Can't be lower than 0.1Mpa when idle, the pressure is too low, the bad lubrication of the engine will cause the wear of each movement;
3. Operation: After the engine is started, the engine is warmed up at low speed and medium speed in sequence. When the engine coolant temperature is higher than 60 degrees and the oil temperature is higher than 45 degrees, the load operation is allowed. And pay attention to the point:
( 1 ) The engine is not allowed to operate at idle speed for a long time
( 2 ) When idle, the oil pressure must not be lower than 0.1Mpa .
( 3 ) The oil pressure, oil temperature, and water temperature during operation should be normal.
( 4 ) If abnormal noise or vibration is found, stop and check immediately.
(5) Pay attention to the sealing conditions of oil, gas, and water. If any leaks occur, they should be immediately eliminated.
( 6 ) The new engine or overhauled engine is not allowed to work at high speed and heavy load from the beginning. In the first 2500 km or 60 hours, the power usage should be reduced and the load should not exceed 65% to ensure good Running in.
4. Parking: The engine should avoid rapid stop and flameout. Before stopping the operation speed should be low 3--5 minutes to allow the engine to cool down, then add idle idle 2--3 minutes is sufficient oil to give the various parts, and parking stall.
It should also be noted that when the ambient air temperature is below 5 degrees, if the engine coolant cannot ensure that no freezing occurs, the coolant should be drained in time to avoid freezing the parts.
When the temperature is below -30 degrees Celsius, the battery should be removed and moved into the interior insulation, otherwise it is difficult to start.
5. Handling Precautions: Compared to the traditional mechanical fuel system, the electronically controlled common rail pump system is more demanding on fuel cleanliness. You must fill the regular gas station with clean fuel. Do not contaminate the raised fuel.
