Fuel preheater for internal combustion engine - is formed by coil of copper pipe wound around engine cooling water pipe

摘要

The fuel supplied to an internal combustion engine is pre-heated before flowing to the carburettor. The fuel is heated by flowing through a copper pipe which is coiled around a flexible hose through which the engine cooling water circulates. To ensure high thermal conductivity electrolyte copper is used for the pipe coil. The fuel is thus heated without the use of an external source of heating. The pre-heating of the fuel reduces the fuel consumption of the engine for a given power output. USE - Internal combustion engine.
