    Abstract: Disclosed is a method of controlling the gas pressure in a dual fluid injection system wherein the gas is used to deliver a metered quantity of fuel to a combustion chamber (60) of an internal combustion engine (20). On detection of an abnormal fuel supply condition, gas pressure in the fuel injection system is regulated to a level less than the fuel pressure deliverable by a fuel supply system of the engine (20) under the abnormal fuel supply condition. In this way, fuel may be delivered as required to the dual fluid fuel injection system.

    Abstract translation: 公开了一种控制双流体喷射系统中的气体压力的方法，其中气体用于将计量的燃料输送到内燃机（20）的燃烧室（60）。 在检测到异常燃料供给状态时，燃料喷射系统中的气体压力被调节到低于在异常燃料供应状态下由发动机（20）的燃料供应系统输送的燃料压力的水平。 以这种方式，可以根据需要将燃料输送到双流体燃料喷射系统。

    Abstract: A control box (11) for a dual-fuel internal-combustion engine (6) is actuated automatically by an oil-pressure switch (16) when activated by a manual switch (30) that directs power from a battery (29) or other engine-electrical component to a current distributor such as a 24-volt bus (49) for operating control-box components that include an under-current sensor (36) for preventing use of gaseous fuel in addition to liquid fuel under no-load and low-load conditions, an over-current sensor (39) for preventing use of gaseous fuel in addition to liquid fuel under excessive-load conditions, an intake-air sensor (17) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of air, a liquid-fuel-supply sensor (22) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of liquid fuel, and an exhaust-gas-temperature monitor (23) for shutting down dual-fuel mode when exhaust heat is excessive.

    Abstract: A vehicle engine management system includes a single engine control unit (4) with a control/processor (22) and store devices (23-25). The vehicle can be powered by gas fuel from tank (27) via gas injectors (6) or by petrol from tank (8) via petrol injectors (2). The control (22) determines whether gas or petrol is utilised dependent on driving conditions using mapping (23, 24). To refuel the vehicle a cycle of operations is carried out by control (22) using the sequences stored in device (25). The presence of a connected gas supply is determined via detector (13a) and gas tank pressure via sensor (27a) and a compressor (28) is operable during the cycle to refuel the tank. Refilling automatically terminates and after this the car can be driven away when fuel line decoupling is detected.
