Abstract
An internal combustion engine injector mounting is configured to i) secure an injector (36) to an internal combustion engine body so that the injector can inject a heated aqueous fluid and a fuel into a combustion chamber of the internal combustion engine, and ii) hold a catalyst so that the heated aqueous fluid and fuel are injected into the combustion chamber by passing through the catalyst. The catalyst is contained within the mounting to protect against oxidation by combustion processes that, in use, take place in the combustion chamber.
Claims16
An internal combustion engine comprising:
- an engine body defining a space in which a movable body moves to define a variable volume combustion chamber;
- an injector mounting body defining a catalyst holding space and being secured in an aperture that is provided in said engine body thereby positioning said catalyst holding space substantially, externally to said variable volume combustion chamber;
- an injector mounted in said injector mounting body and connected with a fuel supply and an aqueous fluid supply;
- and
- a catalyst disposed in a catalyst holding space defined in said injector mounting body thereby subjecting the aqueous fluid received from said injector to a catalytic reaction thereby generating hydrogen products in said catalyst holding space and passing the hydrogen products produced from the catalytic reaction into said variable volume combustion chamber.
An internal combustion engine injector mounting comprising:
- a mounting body interconnected to an aperture in an internal combustion engine cylinder head that partially defines a combustion chamber;
- said mounting body includes an upstream end and a downstream end, and said upstream end being provided with an injector recess to receive at least an outlet end of an injector;
- said downstream end being provided with a catalyst holding space including a catalyst disposed therein and being located external to said combustion chamber;
- and
- said mounting body being provided with a connecting passage extending between said injector recess and said catalyst holding space for providing an aqueous solution to said catalyst thereby enabling said catalyst to initiate a catalytic reaction externally of said combustion chamber.
An internal combustion engine comprising:
- a cylinder head that partially defines a combustion chamber;
- being fitted with an injector mounting that comprises a mounting body fitted to an aperture defined by said cylinder head;
- said mounting body an upstream end and a downstream end, and wherein said upstream end is provided with an injector recess to receive at least an outlet end of an injector;
- a catalyst holding space for holding a catalyst and being disposed at said downstream end of said mounting body;
- and
- said mounting body being provided with a connecting passage extending between said injector recess and said catalyst holding space for providing an aqueous solution to said catalyst thereby enabling said catalyst to initiate a catalytic reaction externally of said combustion chamber.
