Will a Faulty Exhaust Valve Affect Engine Power?
1 Answers
Yes, a faulty exhaust valve can affect engine power. When the exhaust valve is damaged, it cannot properly control the amount of exhaust gas recirculation. Excessive exhaust gas participating in recirculation will affect the ignition and performance of the air-fuel mixture, thereby impacting the engine's power output. This effect is particularly noticeable during engine idle, low-speed operation, small loads, and when the engine is cold. Exhaust Valve: The exhaust valve, also known as an oil separator or pressure control valve, is installed between the compressor outlet and the condenser inlet. Through separation, it improves the heat transfer efficiency in the condenser and evaporator. Working Principle of the Exhaust Valve: High-pressure gas (comprising gaseous working fluid and lubricating oil) discharged from the compressor enters the exhaust valve and passes through its guide vanes. The gas flows in a spiral pattern along the guide vanes, and centrifugal force and gravity separate the lubricating oil from the working fluid gas. The oil flows down along the inner wall of the cylinder. The working fluid gas passes through a multi-hole baffle and is discharged from the central pipe of the exhaust valve. The separated lubricating oil accumulates at the bottom of the oil separator and can be periodically drained or automatically returned to the compressor's crankcase via a float valve.
