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

Sep. 08, 2020

As a Bucket Tooth Supplier, share with you. The intercooler in the excavator is a device used to cool the intake air on the turbocharged engine and is an important part of the supercharging system. If the intercooler is damaged, the turbocharged engine needs to compress the air to increase the intake air volume, and the compressed air will increase the temperature, and the high temperature air entering the cylinder will easily cause deflagration and other dangers.

The role of the intercooler of the excavator: The intercooler is located in front of the engine and looks exactly like the radiator.

1. Reduce the engine intake temperature

2. Reduce engine fuel consumption

3. Improve turbocharger matching and adaptation

Intercooler failure phenomenon

1. The excavator engine sucks in unfiltered dust and foreign particles, which will damage the internal parts of the engine. Common phenomena: heavy exhaust, low speed, reduced engine power, and extremely dirty oil.

2. The turbocharger is damaged, the oil is leaking, and the muffler will spray oil.

3. Blocking of the intercooler will cause poor air cooling and cause abnormally high engine temperature.

Intercooler failure phenomenon

1. Check the air filter element, the supercharger, the air pipes from the air filter element to the engine, and check the connection between the intake pipe and the intercooler for any abnormalities.

2. If the common rail pressure drops due to the diesel oil circuit entering the air in the 8 type engine, the injector will be controlled to increase and the suction air pressure will also decrease, so check the diesel oil circuit to confirm that there is no air in the oil circuit.

3. If there is black smoke or holding the car, check whether the intercooler hose is blocked.
