  • Exhaust gas assisted fuel injection system for internal combustion engine
    Patent number: 6571781
    Abstract: The present invention relates to a fuel injecting apparatus for an internal combustion engine, in which exhaust gas is applied to the injection of fuel. According to the fuel injecting apparatus, a portion of hot exhaust gas is introduced in front of the outlet of the fuel injector allowing hot exhaust gas to promote the fine particle formation and vaporization of fuel thereby enhancing efficiency of fuel. Again, a portion of exhaust gas can be circulated into the combustion chamber to restrict the production of nitrogen oxide. Also, exhaust gas re-introduced into the combustion chamber through the EGR line is cooled by heat of vaporization of fuel injected from the fuel injector thereby advantageously relieving the installation of an additional cooling system for cooling exhaust gas which is re-circulated into the combustion chamber.
