As GOBİZ Academy, we offer a special guide to diesel generator users. In this comprehensive article, we will discuss oil change and general maintenance in diesel generators in detail. By following these steps, you can use your generator for a long time and without any problems.
1. Lubricating Oil and Performance Characteristics
The lubrication system, one of the most important parts of diesel engines, extends the life of the engine and reduces the cost of use with regular maintenance. Lubricating oils have classification and performance categories developed by the American Petroleum Institute (API), ASTM and SAE.
2. Lubricating Oil Recommendations
Choosing the right oil for diesel generators is an important factor affecting engine performance. According to recommendations that vary depending on ambient temperature, it is stated that high quality SAE 15W/40 heavy duty engine oil is recommended. Additionally, a minimum API oil quality level of CH/CI-4 is recommended for generator engines.
Recommended Oils for All Season Use:
5W40-15W40
10W30 (CI-4) - All Seasons
5W30 (CI-4) - All Seasons
Recommended Oils for Winter Conditions:
10W30
5W30
Recommended Oil for Polar Conditions:
0W30
3. Generator Maintenance Program
A good maintenance program is key to the longevity of your generator. By following the maintenance schedule specified below, you can regularly check your generator and detect possible problems in advance.
A. Checks Daily or Every 20 Hours:
The engine, generator, transfer switch and control panel are visually controlled.
Check whether there is any oil, water or fuel leakage.
Battery charge level is checked.
The operation of the water heater is checked.
B. Weekly Checks:
Daily checks are repeated.
The fuel system is checked.
The cooling system is checked.
The alternator is checked.
The transfer switch is controlled.
C. 6 Months or Every 200 Working Hours:
Weekly checks are repeated.
Lubrication system maintenance is carried out.
Fuel system maintenance is done.
Cooling system maintenance is done.
Engine safety checks are carried out.
D. Once a Year or Every 800 Working Hours:
Maintenance is repeated every 6 months.
The fuel system is checked in detail.
The cooling system is checked in detail.
The air circuit is checked.
Cleaning and visual checks are carried out.
E. In 2 Years Or 2000 Working Hours:
Detailed maintenance is repeated.
Turbo charger bearing clearance is checked.
Exhaust resistance is checked.
Valve settings are checked.
Engine coolant is replaced.
Turbocharger compressor cleaning is done.
4. Diesel Engine Malfunctions and Troubleshooting
Possible malfunctions that may be encountered in diesel engines and their solution methods are listed below. By reviewing the detailed explanations for each situation, you can solve the problems in your engine.
