How Often Should Diesel Engine Fuel Injectors Be Calibrated?

[DeLena]

Diesel engine fuel injectors should be calibrated every 500 hours of operation. The fuel injection timing angle should also be rechecked and adjusted. Early signs of fuel injector damage include: Engine vibration: When fuel injectors become damaged and fuel spray becomes uneven, the engine may exhibit symptoms like operational vibration during operation. Decreased power and increased fuel consumption: As injectors deteriorate, fuel injection quantity and pressure can't be properly maintained, leading to symptoms of reduced vehicle power and increased fuel consumption. Increased exhaust emissions: Faulty fuel injectors inevitably affect the mixing and combustion of the air-fuel mixture, resulting in increased pollutant emissions from vehicle exhaust. Starting difficulties or even stalling: If fuel injectors become severely damaged, the vehicle may experience starting difficulties and even sudden stalling during operation.
