Importance of Engine Preservation
If an engine is likely to be kept idle for longer than normal due to any reason, it is recommended that steps for preservation as per the OEM commendations are to be taken to keep the engine in good working condition, minimizing the potential for their deterioration. Engine preservation becomes critical during times of long standstill/storage. In the light of past experience some unfortunate (and significant time- and cost-consuming) effects when the correct procedure are not followed.
The Consequences of Not Preserving the Engine
The cost of failing to preserve the engine during a time of idleness could be very high indeed.
A typical work scope for an unpreserved engine can include removal for overhaul and potentially a compete teardown to inspect all mainline bearings. It may be necessary to exchange the fuel pump, fuel control, fuel manifolds, oil pump, and several other major parts along with the replacement of all necessary bearings.
Pre- preservation preparation
Preservation of a Diesel Engine
The preservation of Diesel generator is the important part of storage. Carry out the preservation to protect the Diesel generator for the following reasons.
1. Protection against corrosion befor next delivery.
2. Before initial starting.
3. Before shipment and transpiration.
4. For the long time standstill.
1. Cooling Water System
2. Fuel Oil System
3. Lubricating Oil System
4. Combustion Chamber
5. Intake Air Chamber
6. External Machined Surface
7. The Others.
A. Cooling Water System
- Drain the cooling water from the High Temperature, Low-Temperature and cooling water system
- Charge air cooler
- Lube oil cooler,
- Then blow air from inlet to outlet of cooling water piping system to remove the remaining water.
- Spray the corrosion inhibitor into the system using an air-gun. or similar after removing impurities, rust, etc.
- And then seal up those systems with blind covers to prevent the loss of vapor.
- Discharge the air in the system and fill the nitrogen gas to 1bar.
B. Fuel Oil System
Drain the fuel oil from the piping system and fuel oil filter.

1. Crankcase inside,
2. Connecting Rod,
3. Crankshaft –
4. Piston lower,
5. Cylinder Liner and
7. Cam Roller and Chamber inside
8. Gear Train and chamber inside
9. Cylinder Head Top Cover inside and Rocker Gear
The rust protection oil should also have proper. lubricating oil pr.
The preservant should not cause any defect to the. Parts even if mixed with engine oil.
Pay close attention to use an excellent product for. of similar type.
D. Combustion Chamber
Inject corrosion preventive fluid. < BW-70PSJ, Mobilarama524, or similar >. in a quantity of 0.5 liters per cylinder into the combustion chambers. Through the indicator valves. Turn the crankshaft by 2~3 revolutions.
The old method of preservation of an Engine was to spray preservative oil through the pre-combustion chamber of a Compression Ignition Engine and spark plug hole of a spark ignition engine. This preservation method is unsatisfactory since the procedure consumes time involving the removal of spark plugs and injectors from the engine. Injection of the preserving oil is challenging through the small opening. In this procedure, oil film breaks after a period. Water vapors get condensed, resulting in corrosion on exposed parts.
The present preservation method will provide an easy practice and minimizes the tendency of rust on the interior parts. In this preservation practice, the inert non-corrosive gaseous agent is introduced inside the engine combustion chamber.
E. Intake Air Chamber ( How to store a Diesel Generator )
Remove the impurities like rust etc. Spray the volatile corrosion inhibitor. < VCiR-3P or similar(VpCI-377)>. into the system. by using an air-gun or similar. And then seal up those systems with blind covers to prevent the loss of vapor.
