Liquid fuel vapourisation apparatus (20) including: first pressure reduction means (43, 44) for receiving liquid fuel and reducing its pressure to a first controlled pressure to vapourise at least some of the fuel; a vapouriser (50) in fluid communication with the first pressure reduction means (43, 44) for receiving the partly vapourised fuel and vapourising the remainder of the liquid fuel to provide a gaseous fuel; a second pressure reduction means (47, 48) in fluid communication with the vapouriser (50) for receiving the gaseous fuel and reducing its pressure thereof to a second controlled pressure for delivery (17) to one or more of the fuel injectors of an internal combustion engine. The first and second pressure reduction means (43, 44, 47, 48) are either operatively interposed between the throttle body and the intake manifold of the engine or operatively incorporated into a throttle body. |
