👉 The registry fluid, often abbreviated as RGF (Registered Fluid Gas), is a crucial component in the operation of internal combustion engines, particularly in diesel engines. It is a mixture of gases that results from the incomplete combustion of fuel and lubricating oil within the engine's cylinders. Unlike regular exhaust gases, which are expelled from the engine, registry fluid is recirculated back into the combustion chamber to re-ignite the fuel-air mixture, ensuring continuous combustion and efficient operation. The fluid's composition can vary based on engine design, fuel type, and operating conditions, but it generally includes a blend of hydrocarbons, water vapor, and oil residues. Proper management of registry fluid is essential for maintaining engine performance, reducing emissions, and prolonging engine life.
