The turbocharged air intake side of Carter gas engines exhausts air outward during loaded operation
Thread Content
After being loaded, the Caterpillar G3516 gas engine draws in air on the turbocharger’s intake side for about ten seconds, and then expels the air once or twice. Its rotational speed also fluctuates by around 20 RPM. Does anyone know what could be causing this?
Based on your description, the Caterpillar G3516 gas engine experiences air backflow on the turbocharging intake side when under load, and its speed also experiences some fluctuations. This may be caused by one of the following reasons: 1. Problem with the exhaust valve: The exhaust valve cannot close completely or there is a leak, allowing some air to flow back to the intake side of the turbocharger. 2. Turbocharger failure: The rotating components or seals of the turbocharger may be damaged or worn, causing air to flow back. 3. Intake pipe issues: Leaks or other blockages in the intake pipe prevent air from flowing properly into the turbocharger, thereby causing backflow. 4. Insufficient fuel supply: If the fuel supply is inadequate or there are problems with the fuel system, it can lead to unstable engine operation, thereby causing air backflow on the intake side of the turbocharger. In light of the possible causes mentioned above, it is recommended that you contact professional technicians for inspection and repair to ensure the safe operation of the engine. .
