A diesel generator combines an electric generator (usually an alternator) with a diesel engine to produce electrical energy. Although fuel oil is typically the primary fuel for diesel compression-ignition generators, they can run on natural gas or other liquid fuels. These generators require less maintenance because of their durability, longevity, and dependability. They are also less expensive to operate because their fuel prices are lower than those of other fuels like gasoline and propane.
Diesel generators can quickly get the power supply up to full load and withstand large loads for extended periods; nevertheless, frequent maintenance is necessary to maintain high power output for the duration of their service lives.
You must change filters and oil in your diesel generator at specified intervals. Turn off the generator regularly and check the engine oil with a dipstick. Let the oil in the engine’s upper sections drain back into the crankcase as you follow the API oil classification and viscosity standards supplied by the engine manufacturer. Add the same grade and brand of oil to maintain the oil level near the full indication on the dipstick.

Check the fuel
This is a crucial detail to remember when maintaining diesel generators. It is strongly advised to regularly run generator sets to burn through stored fuel before it deteriorates because diesel can get contaminated and corroded in as little as a year. Fuel filters must be drained at certain intervals because the water vapor builds up and condenses inside the fuel tank.If the fuel is not utilized and is replenished every three to six months, it may be necessary to do routine testing and polishing.
The cooling mechanism
Verify the coolant level at predetermined intervals during shutdown periods. Once the engine has cooled, please remove the radiator cap and top the coolant until it reaches about 3/4 of the way up. Additionally, check your coolant filters and change them as necessary. Heavy-duty diesel engines need a balanced coolant mixture of water, antifreeze, and coolant additives.
Look for obstructions on the outside of the radiator and use a soft brush or cloth to remove any debris, being cautious not to harm the fins. Another crucial component of maintaining a diesel generator to reduce overheating and high engine temperatures is radiator flushing.Use a stream of water flowing in the opposite direction of the usual airflow or low-pressure compressed air if it is available for radiator cleaning.
Weak or undercharged starter batteries commonly cause standby power system failures. Maintaining the battery in a charged state is imperative to prevent declining effects. Regular testing and inspection are necessary to ascertain the battery’s present condition and prevent any complications during generator startup. Regular checks of the battery’s electrolyte levels and specific gravity are also essential with cleaning.
Testing batteries: It is impossible to ascertain whether batteries can supply sufficient starting power by measuring their output voltage. The only accurate technique to measure terminal voltage is when the battery is under load because its intrinsic resistance to current flow increases as batteries age. Specific generators automatically run this suggestive test every time they turn on. Examine the state of each starting battery on additional generator sets using a manual battery load tester.
Maintain the cleanliness of your diesel generator.
It is simple to locate and repair oil leaks and other issues in a well-maintained engine. You can visually inspect belts and hoses to ensure they are operating well. Regular inspections will keep wasps and other nuisances from building their nests inside your equipment. The more the usage and dependence on a generator, the higher the maintenance needs. Conversely, an infrequently used generator set might not need as much maintenance. Other considerations are as follows:
Cleaning the air purifier: The air cleaner should be serviced using a unique, highly porous cardboard filter element after 500 hours of engine operation or the clogged signalize, if necessary.
Cleaning the breathers on engines: Diesel fuel should be used to clean the engine breathers every 2,000 hours of operation. Diesel generator breathers are cleaned and purged using compressed air after the housings are removed, and the breathers are separated from the cylinder head cover caps.
Monitoring the electrolyte level in open-cell lead-acid batteries: Open-cell lead-acid batteries should be checked at least every 200 hours. If the battery cells are low, fill the filler neck with pure water to the bottom. Unplug the batteries at all times when the generator is not in use. Click here, to find out more.
Inspection of the exhaust system
Locate any leaks in the exhaust system and have a specialist fix them immediately. This is important for any exhaust line leaks, which often happen at the welds, gaskets, and connection points.
Routine general examination
Like any internal combustion engine, proper maintenance is essential. When your diesel generator is operating, it is vital to watch closely for any leaks that could cause hazardous conditions in the fuel system, DC electrical system, exhaust system, and engine. Like other diesel engines, oil changes every 500 hours of functioning are essential for ensuring a long and trouble-free life.
However, some applications may require less frequent servicing, so after-sales services must be of the highest caliber. Inspect your diesel generator once or twice a month for better maintenance. In addition, the alternator, controllers, AVR, and entire sensor system, together with the wiring and harnesses for integrity, must all undergo routine examinations.
To conclude, adhering to the manufacturer’s recommended maintenance schedule for your generator will guarantee optimal performance and maximum service duration. Frequent inspections help to ensure engine starting dependability, maintain engine parts lubricated, and avoid oxidation of electrical contacts. It also burns fuel before it degrades. You should load the engine to at least one-third of its nameplate rating every month and do an engine exercise lasting at least half an hour.
