CATALYST MOUNTING IN INTERNAL COMBUSTION ENGINES

An internal combustion engine injector mounting is configured to i) secure an injector () 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.
