Abstract
The invention provides a gas fuel supply kit for the existing vehicle (vehicle mounting a gasoline engine, or a diesel engine), in order to use a gas fuel such as hydrogen after wards. A post-installable type gas fuel supply kit to be installed in the existing vehicle such as a gasoline vehicle, comprising a gas fuel injector for supplying the gas fuel such as hydrogen to an intake path; an injector installing means for installing said gas fuel injector to a location which is a different location where a gasoline injector is installed; and a control unit for controlling at least an injection amount, and an injection timing of the gas fuel at the hydrogen fuel injector.
Claims7
A post-installable type gas fuel supply kit to be installed in an internal combustion engine using liquid fuel as a fuel, characterized by comprising:
- a gas fuel injector for supplying the gas fuel to a combustion chamber of said internal combustion engine, or an intake path leading to said combustion chamber;
- an injector installing means for installing said gas fuel injector to a location which is a different location where an injector injecting the liquid fuel is installed;
- and
- an injector control unit which is separately provided from a previously provided engine control unit to a vehicle,
- wherein, said injector control unit comprises a program for controlling at least an injection amount, and an injection timing of the gas fuel at the gas fuel injector.
A gas fuel supply kit used in a cylinder direct injection type internal combustion engine comprising a liquid fuel injector for directly injecting a liquid fuel to a cylinder, and an injector holding part for holding said liquid fuel injector in the cylinder, characterized by comprising:
- a liquid fuel injector installing means for relocating said liquid fuel injector to an intake manifold and for holding it there;
- a gas fuel injector, being installed to said injector holding part, for directly injecting the gas fuel to the cylinder;
- and
- an injector control unit which is separately provided from a previously provided engine control unit to a vehicle,
- wherein, said injector control unit comprises a program for acquiring injector pulse from said previously provided engine control unit to control at least an injection amount, and an injection timing of the gas fuel at the gas fuel injector.
A gas fuel supply kit used in an internal combustion engine in which a liquid fuel injector for supplying a liquid fuel is installed to an intake manifold therein, characterized by comprising:
- a gas fuel injector for supplying a gas fuel within said intake manifold;
- a gas fuel injector installing means for installing said gas fuel injector to said intake manifold;
- and
- an injector control unit which is separately provided from a previously provided engine control unit to a vehicle,
- wherein, said injector control unit comprises a program for acquiring injector pulse from said previously provided engine control unit to control at least an injection amount, and an injection timing of the gas fuel at the gas fuel injector.
