The Inlet Valve 751‑40550 is a precision engine component engineered to regulate the intake of air (and air/fuel mixture) into the combustion chamber of diesel engines. Installed in the cylinder head, this valve ensures the right amount of fresh air enters each combustion cycle — a critical process for efficient fuel combustion, power output, and smooth engine operation.
Where It Is Used
-
Commonly fitted in Lister Petter engines such as LPW, LPW2, LPW3, LPW4 and related Onan DN series engines.
-
Suitable for diesel generators, industrial engines, and heavy machinery that use these engine models.
-
Essential for engine rebuilds, overhauls and maintenance to restore performance and reliability.
Key Functions
-
Controls air intake: Opens and closes at precise timing to allow clean air into the combustion chamber.
-
Supports efficient combustion: Proper air intake helps optimize fuel burn for better power and fuel economy.
-
Protects engine internals: Maintains proper airflow, reducing carbon build‑up and premature wear.
-
Durable construction: Made from hardened materials to withstand high temperature and pressure.
