<p>A fuel supply system (10) for an engine (20) has a pair of pressure vessels (22, 23) in parallel. As one vessel (22, 23) receives liquid fuel from a tank (14) via a pump (15) and vaporizes the fuel using a heater (29, 30), the other vessel (22, 23) supplies vaporized fuel to the engine (21) via a main vapour line (44). A pulse of petrol may be supplied to the engine (21), at either idle or part throttle, via a solenoid valve (18) in a branch line (17) which is provided in parallel to the pressure vessels (22, 23). At full throttle, the engine (21) is supplied only with liquid petrol. The system (10) is controlled by an electronic logic control system (12) which has a microprocessor (46) which is connected to sensors (36, 37, 49, 51, 52) and which controls the operation of the solenoid valves (18, 24, 25, 40, 41) to control the flow of liquid or vaporized petrol in the system (10).</p> |
