Dongfeng 6ltaa8.9-c325 engine, normal starting requirements
a. Cummins starter runs for no more than 30s each time, and the time interval for starting again is 2min.
b. The lubricating oil pressure should reach 70kpa within 15s after starting, otherwise check the oil level immediately.
c. The load can only be increased after 3-5min idle speed after starting, otherwise the bearing bush will be short of oil supply instantaneously.
d. Idle speed should not exceed 10min, otherwise there will be carbon deposit in combustion chamber and leakage of Cummins engine supercharger.
e. Cummins engine water temperature should not be lower than 60 ℃, otherwise the fuel will enter the engine oil and damage the lubrication. Use the empty car to accelerate to increase the water temperature.
f. After starting in winter, keep idling until the pointer of water temperature gauge turns or starts running after 10min. When observing the water temperature gauge, pay attention to whether the oil pressure gauge meets the requirements. When using auxiliary starting fluid in winter, it is necessary to use a sprayer with a quantity of holes.
Dongfeng Cummins 6ltaa8.9-c325 engine, basic operation requirements
a. During the operation of Cummins engine, the instrument should be observed frequently: the water temperature should be between 74 ℃ - 91 ℃; the oil pressure should be greater than 70kpa at idle speed and 276-517kpa when it is above 1200R / min.
b. If Cummins Engine overheats, reduce load operation. If it is overheated after reducing the load for a period of time, it should be stopped to check the fault.
c. During the operation of Cummins engine, pay close attention to the changes of the following conditions of the engine. If any of these changes suddenly, it is likely to be a precursor of failure. Please check and repair it in time.
① Engine fire or fire is not good; ② vibration; ③ engine abnormal noise; ④ sudden change of engine working pressure and temperature; ⑤ engine exhaust smoke is too large; ⑥ engine power is insufficient; ⑦ oil consumption is increased; ⑤ fuel consumption is increased; ⑤ fuel, oil or water leakage.
