Intake apparatus 101 and method for an engine 105 comprising: an intake conduit 110 through which intake gas may flow into a combustion chamber of the engine 105 ; a heating element 140 for heating intake gas passing through the conduit110; and injection means 130 for injecting fuel into the conduit 110, the fuel injector 130 being operable to inject fuel into the conduit 110 in a direction such that when intake gas is flowing through the conduit 110 at a first flow rate a trajectory (flowpath FL) of fuel is such that fuel impinges on the heating means 140 and when intake gas is flowing through the conduit at a second flow rate different from the first flow rate the trajectory (flowpath FM) of fuel is modified by the flow of intake gas such that fuel does not impinge on the heating means 140. The fuel may be injected into the conduit 110 in a direction upstream, downstream, parallel or normal to the direction of flow of the intake air. |
