Manual Extract: Troubleshooting Excessive Engine Smoke

The following issues may lead to excessive smoke emission from the engine, especially when under load. Review these potential problems and their solutions:

• Air Leaks Between Turbocharger and Manifolds:

  Air leaks can cause an incorrect air-to-fuel ratio, resulting in reduced engine power. Ensure all gaskets are intact and properly sealed.

• Multiple Seal Washers on Injector Nozzle:

  Extra seal washers can lead to sealing issues and low compression. Confirm the removal of old washers and replace with a new seal washer.

• Fuel Injection Nozzles Malfunction:
  • Low cracking pressure
  • Incorrect spray pattern
  • Closed spray orifice

  Test and service the fuel injection nozzles to ensure proper engine combustion.

• Turbocharger Functionality Issues:

  A malfunctioning turbocharger may fail to provide necessary compressed air, leading to poor air-fuel mixture and power loss. Inspect for wear and ensure proper lubrication with a freely turning compressor wheel.
