Fuel costs typically represent the single highest operating cost associated with any diesel engine application. This has promoted various fuel conservation practices that can usually be applied to all applications.
- Avoid fuel spillage. Do not overfill the fuel tank. Fuel expands when warm and may overflow, especially when
tank is not designed correctly. - Operate the engine with a good electrical system. One bad cell in a battery will overwork the alternator, consuming more engine horsepower and fuel. A poor electrical system can also lead to hard starting, which
encourages excessive idling. - Size the engine or generator set to the job. Engines operate more efficiently at relatively high load factors.
- Do not increase fuel settings to obtain more power.
- Make sure all air hoses and connections do not leak.
Leaks keep the compressor working unnecessarily. - Make sure the turbocharger is turning freely so that proper air-fuel ratio is maintained.
A clean burning exhaust should indicate these items are functioning correctly. - Operate the engine with a thermostat all year; cold engines consume more fuel and wear out more quickly.
- Keep air cleaners clean. Use an air cleaner restriction indicator to avoid guessing at air cleaner condition.
