Abstract:
1. An injection control system for supplying fuel vapour to an internal combustion engine, comprising: a fuel tank; a fuel tank vapour line coupled to said fuel tank; a purge vapour collection canister coupled to said fuel tank vapour line; a purge vapour line coupled to said purge vapour collection canister; at least one fuel injector disposed in an air intake manifold and coupled to said purge vapour line via a controllable valve; a liquid fuel injection delivery device; a liquid fuel line coupled to said liquid fuel injection delivery device and to said at least one fuel injector; and an electronic control unit for determining the state of the fuel in the liquid fuel line based on the output of said sensors, where said electronic control unit is arranged to control the controllable valve for permitting delivery of fuel vapour from the purge vapour collection canister to the air intake manifold dependent on the current state of the fuel in the liquid fuel line.
