Abstract: Intake apparatus for an engine that includes an injector for injecting fuel into a flowstream of intake gas through the apparatus and a heater for heating intake gas passing through the apparatus. The apparatus being operable to inject fuel into the flowstream of intake gas by means of the injector such that when intake gas flows through the apparatus at a first flow rate injected fuel impinges on the heater; and when intake gas flows through the apparatus at a second flow rate greater than the first a flowpath of injected fuel is deflected by intake gas such that substantially no fuel impinges on the heater.

Abstract: A throttle assembly comprising: a body portion defining a gas flow channel, the body portion being arranged to allow a flow of gas to be established through the gas flow channel from a gas inlet to a gas outlet of the assembly; and an injector arranged to inject fuel into the gas flow channel, wherein the injector is arranged such that a centreline of a flow of fuel from the injector is substantially parallel to a centreline of a portion of the channel into which fuel is injected thereby to reduce an amount of fuel impinging on a sidewall of the channel.
