Working Principle and Core Function of CNG Reducer

A CNG reducer, also called vaporizer, is the heart of the autogas system. CNG stored in vehicle cylinders is under 200bar high pressure, which cannot be directly used by car engines. The reducer reduces the high pressure step by step to a safe and stable working pressure. Meanwhile, it uses engine cooling water to heat the gas to avoid freezing and gas blockage. Stable reducer performance directly affects vehicle idle stability, power output and driving safety. Most vehicle gas failures are caused by aging or poor-quality reducers. Regular filter replacement and maintenance can greatly extend the service life of the entire gas system.
