The main reason for white smoke emission from the engine of CAT 320D excavator

Improper or incorrect operation: Incorrect operation may cause white smoke from the engine of the Caterpillar 320D excavator.

Fuel supply issue: Poor fuel supply or poor fuel quality may result in white smoke emissions.

Coolant temperature circuit malfunction: A malfunction in the coolant temperature sensor or circuit may result in white smoke emission.

Hydraulic electronic control unit injector failure: Injector failure can affect combustion and cause white smoke.

Combustion malfunction: Insufficient combustion or low external temperature may result in white smoke emission.

Air inlet heater malfunction: Air inlet heater malfunction may result in white smoke emission.

High air intake resistance: The presence of resistance in the air intake system may result in white smoke emissions.

Bent connecting rod or damaged cylinder liner: After the machine tilts, bent connecting rod or damaged cylinder liner may cause white smoke to be emitted.

Formal operation: Ensure to follow standard operating procedures, especially in cold environments.

Check fuel supply: Check fuel quality, fuel pressure, and fuel system to ensure smooth fuel supply.

Check the coolant temperature circuit: Use ET to check the coolant temperature sensor and circuit to ensure normal operation.

Check the fuel injector: Ensure that the hydraulic electronic controlled single unit fuel injector is connected properly, without corrosion or damage.

Check the combustion condition: Check for combustion faults to ensure sufficient combustion, especially in low-temperature environments.

Check the intake heater: Ensure that the intake heater circuit and components are working properly.

Check the air intake system: Ensure that the air intake system is unobstructed and unobstructed.

Dealing with connecting rod and cylinder liner issues: If the Caterpillar 320D used excavator has a rollover accident, ensure that the connecting rod and cylinder liner are not damaged and replace or repair them if necessary.
