Before most of the failure, engine will develop early warning in the
from of abnormal sound, changes in parameter and performance or
engine appearance. Close monitoring of the engine will help to
detect the failure in the preliminary stage.
Few signs, to look out for are as below:
‒ Leakage of oil fuel, coolant, compressed air or exhaust gas
‒ Color change in exhaust gas
‒ Rise/drop of pressure and temperature
‒ Excessive vibration
‒ Sudden unusual noise
‒ Misring of engine
‒ Rise in oil/fuel consumption
‒ Power loss
Operation of diesel engine in winter
1. Fuel: Select and use the diesel of different brands according to the outdoor
temperature in winter.
2. Oil: Select the oil with different viscosities according to different seasons.
3. Coolant: Select and use different brands of anti-freeze additive and add
additive in different quantity into the cooling system according to the outdoor
temperature.
