INDEPENDENT FUEL INJECTING SYSTEM OF COMPRESSED NATURAL GAS ENGINE

摘要

PURPOSE: An independence fuel injection system of a CNG(Compressed Natural Gas) engine is provided to facilitate the installation of an injector module without changing a cylinder head by installing an injector spraying a fuel to each cylinder in an appointed area of an intake manifolder which is adjacent to a connection part between the intake manifolder and the cylinder head. CONSTITUTION: An independence fuel injection system of a CNG(Compressed Natural Gas) engine comprises a cylinder head(6), an intake manifolder(5), and an injection module. The cylinder head has an intake port(6a) of an engine which uses compressed natural gas as a fuel. The intake manifolder is connected to the cylinder head in order to supply outdoor air to the cylinder head. The injection module is installed at an appointed area of the intake manifolder adjacent to the cylinder head, and spraying the compressed natural gas fuel towards the intake port.
