LAMBERT POWER Diesel Engine Operation and Maintenance Manual
Temperature for coolant exit 75～95℃
Exhaust temperature after turbo≤600℃
Intake temperature after air intercooled 55±5℃
4.5 Cautions in use
While starting engine, if it does not start successfully within 15 seconds, re-start after 2
minutes interval. If it can’t be started by three successive starts, stop starting immediately.
Find out the reason, trouble shoot and then restart..
After engine start, run several minutes at idle speed, then raise the speed to rated speed
and add the load. Only when outlet water temperature is higher than 60℃ and oil temperature
is higher than 50℃, engine can run at full load. The add of load and speed should be given
gradually. Never add or reduce the load suddenly.
4.6 Engine operation in winter
Fuel: Choose different grades of fuel according to the outdoor temperature in winter.
Lubricating oil: Choose different viscosity of lubricating oil as per different seasons.
Coolant: Choose different grades and amount of coolant as per the outdoor temperature
in winter.
Start: In winter , if necessary ,use auxiliary starter. After engine start, when oil
temperature and water temperature are normal, apply the load and run at high speed
Battery: Before cold season begins, do check electrolyte level, viscosity and unit
voltage
Engine stop
Under the cold season when stopping engine, fist take off the load, and then run it for 5
minutes at idle speed. When the temperature comes down, it can be stopped. If coolant is not
added antifreeze additive, open water drain valve or water seal plug in cylinder block side,
radiator and inlet water pipe to drain out coolant in case of frost crack.
5. Periodic checkup and technical maintenance
Correct maintenance and upkeep of engine is the important step to ensure engine to work
