Cummins engine normal starting requirements:

　　1. Cummins starter does not exceed 30s each time, and the restart time interval is 2min;

　　2, the lubricating oil pressure should reach 70KPa within 15s after starting, otherwise check the oil level immediately;

　　3. After starting, the load can be applied at idling speed for 3-5 minutes, otherwise the bearing bush will be insufficiently supplied with oil instantly;

　　4. The idle speed cannot exceed 10 minutes, otherwise there will be undesirable phenomena such as carbon deposits in the combustion chamber and oil leakage from the Cummins engine supercharger;

　　5. The water temperature of Cummins engine should not be lower than 60℃, otherwise the fuel will enter the oil and destroy the lubrication. The water temperature can be increased by accelerating with an empty car;

　　6. After starting in winter, keep idling until the pointer of the water temperature gauge rotates or enter operation after 10 minutes. While observing the water temperature gauge, pay attention to whether the oil pressure gauge meets the requirements. When using starter fluid in winter, be sure to use a sprayer with a metering hole.
