Turbocharger damage will likely bring engine power, exhaust black smoke, excessive oil consumption, exhaust blue smoke, turbocharger noise, the compressor or turbo seal at the lubricant leakage and other problems, the user should be clear turbocharger makes different sounds, different noise levels when working is a signal that the air is blocked or dirt has built up in the compressor housing.
Turbocharged generators
Diesel generator sets have many parts, no matter which one of the parts have problems, will affect the normal operation of the unit to a greater or lesser extent, and turbocharger damage will likely bring engine power, exhaust black smoke, oil consumption is too large, blue smoke exhaust, turbocharger noise, the compressor or turbo seal lubricating oil leakage and other problems, the user should be clear turbocharger issued The different sounds, different noise levels when working is a signal that the air is blocked or dirt has built up in the compressor housing. Some common diagnostic tests to determine turbocharger problems include.
(1) Blockage in the intake tract of the turbocharger.
(2) Air leak in the pipe between the compressor and the intake manifold.
(3) Exhaust system obstruction.
(4) Air leakage from the contact surface between the intake manifold and the engine.
(5) Blockage in the middle case of turbocharger.
(6) Dirt on the compressor impeller and diffuser guide blade.
(7) Damaged turbocharger.
(8) Exhaust leakage into the turbine inlet exhaust manifold or exhaust manifold.
(9) Blockage in turbocharger oil drain line.
(10) Obstruction in turbocharger intermediate housing.
(11) PCV system obstruction.
(12) Exhaust gas bypass valve boost pressure is incorrect.
Excessive boost pressure is due to.
1. Exhaust gas bypass valve or exhaust gas bypass valve control valve stuck
2. The control valve is stuck in the closed position.
3. Vacuum hose is cut or clamped.
4. Internal computer failure.
Insufficient boost pressure is caused by
1. Exhaust gas bypass valve stuck in open position.
2. Control valve stuck in open position.
3. Computer (PCM) unit failure.
In the turbocharger mechanism maintenance, we must pay attention to the unit first after stopping the operation, not in the diesel generator set is running on the turbocharger maintenance work, at the same time in the maintenance, must wear protective glasses, just stop the unit parts are still very hot, touch them may cause serious burns, beware not to be turbocharger parts sharp edge cut to the hand.
