What are the Reasons for the Engine Wear of the Excavator?

As a bucket gear supplier, we would like to share with you. The intercooler in the excavator is a device used to cool the intake air on the turbocharged engine, which is an important part of the supercharging system. If the intercooler is damaged, the turbocharged engine needs compressed air to increase the air intake, and the compressed air will make the temperature rise, and the high temperature air entering the cylinder will easily cause explosive combustion and other dangers.

The role of excavator intercooler: intercooler is located in front of the engine, the shape is cool like a radiator.

1. Reduce the engine intake air temperature

2. Reduce engine fuel consumption

3. Improve turbocharger matching and adaptability

Intercooler failure phenomenon

  • excavator engine inhalation of unfiltered dust and foreign matter, will damage the internal parts of the engine. Common phenomena: large exhaust volume, low speed, reduced engine power, and extremely dirty oil.
  • turbocharger damage, oil leakage, muffler oil spray.
  • intercooler blockage will cause poor air cooling, resulting in abnormally high engine temperature.

  • Intercooler failure phenomenon
  • check the air filter, supercharger, air filter to the engine air pipe, check the connection between the air intake pipe and the intercooler for any abnormalities.
  • if the type 8 engine diesel fuel line into the air caused by the common rail pressure drop, the injector will be controlled to rise, the suction pressure will also be reduced, so check the diesel fuel line to confirm that there is no air in the fuel line.
  • if black smoke or holding the car, check whether the intercooler hose is blocked.
