How to Deal with Turbocharger Failure?

The role of the turbocharger is to increase the output power of the engine, and if the turbocharger fails, it will affect the entire machine.

Today LANDTOPMALL will teach you how to deal with turbocharger failure. LANDTOPMALL will introduce a troubleshooting method.

Turbochargers are important parts used to increase engine power and reduce exhaust emissions. Due to improper use, maintenance and maintenance, it is prone to failure, resulting in the engine not working properly.

Turbocharger

The following are some common faults and solutions of turbochargers:

Oil Spill

Phenomenon

The oil consumption is large, but the exhaust smoke color is normal, and the power is not reduced.

Reason

This situation is generally caused by oil leakage.

Approach

First, check whether the external oil pipes of the engine lubrication system (including the supercharger inlet and oil return pipes) leak oil. Second, check the supercharger exhaust outlet for organic oil. If there is oil, it can be determined that the sealing ring at one end of the turbine is damaged, and the sealing ring should be replaced.

Phenomenon

The oil consumption is large, and the exhaust emits blue smoke, but the power does not drop.

Reason

Due to the oil leakage at the end of the supercharger, the oil enters the combustion chamber through the engine intake pipe and is burned. There are the following possibilities: First, the oil return pipe of the supercharger is not smooth, and the oil is in the rotor assembly. Too much accumulation at the intermediate support flows into the compressor impeller along the rotor shaft. Second, after the sealing ring or oil throwing ring near the compressor impeller is damaged, the oil enters the impeller chamber from this, and then enters the combustion chamber through the inlet pipe together with the pressurized air in the chamber.

Approach

First, open the air outlet of the compressor or the straight air intake pipe (rubber hose) of the engine to see if the nozzle and the wall of the pipe adhere to the oil. If so, please check whether the oil return pipe of the supercharger is unobstructed. If it is not smooth, it is caused by excessive oil accumulation at the intermediate support, and the oil return pipe should be dredged and then installed. Secondly, if it is unobstructed, it is caused by the damage to the sealing ring or the oil throwing ring at one end of the impeller, and the supercharger should be disassembled for repair.

Phenomenon

The oil consumption is large, the exhaust emits blue smoke or black smoke, and the power drops.

Reason

First, the gap between the piston and the cylinder is too worn, and the oil escapes into the combustion chamber and is burned. Second, when the air is sucked in by the supercharger, the air flow encounters a large resistance. (For example, the air filter element is blocked, the intake hose is sucked and deformed or flattened, etc.), the pressure at the air inlet of the compressor is low, causing oil leakage into the compressor, and the compressed air enters the combustion chamber and burns.

Approach

First, check whether there is oil in the wall of the intake straight hose and whether it is flattened so that the airflow is blocked or the air filter element is blocked. Second, if there is oil in the nozzle and pipe wall, the air filter element should be cleaned or replaced.

Well, that’s it for today’s introduction to the troubleshooting of the turbocharger. If you want to know more about the troubleshooting methods of turbochargers, pay attention to LANDTOMALL, you will have unexpected surprises.
