1. compression ignition internal combustion engine with dual fuel injection ability, it can be operated and be used for pure diesel combustion pattern or pre-mixed charging compression-ignition mode, comprising:

  • The cylinder casing that is holding at least one cylinder;

    The piston assembly that can in described cylinder, operate;

    Cylinder head defines entry port, be fixed on the described cylinder casing and described piston during near the top dead center of compression stroke and described piston form the firing chamber;

    Suction port is used for allowing that air enters described cylinder during the aspirating stroke of described piston;

    Main fuel injector, the fuel A that operation is used for measuring quantity is directly injected into described cylinder;

    Second fuel injector, the fuel B that operation is used for measuring quantity is delivered to described cylinder;

    Gas exhaust manifold is used for during the exhaust stroke of described piston assembly discharging the product of combustion process;

    Gas recirculation system, operation is used for the EGR gas of some is provided to described cylinder;

    AndEngine loading is made the control module of response, be used for optionally controlling described main fuel injector and described second fuel injector and be delivered to described cylinder and control described gas recirculation system so that will measure the described fuel A and/or the fuel B of quantity.
