    Abstract: A method of operating an engine assembly (10) having a cylinder assembly (26) which defines a combustion chamber (46) is disclosed. The method includes the steps of performing an intake stroke of the cylinder assembly (26) and advancing a conditioning fuel into the combustion chamber (46) during the intake stroke performing step. The method further includes the steps of advancing a gaseous fuel into the combustion chamber (46) during the intake stroke performing step and performing a compression stroke of the cylinder assembly (26) after the intake stroke performing step. The method yet further includes the steps of advancing a pilot fuel into the combustion chamber (46) during the compression stroke performing step and combusting the pilot fuel in the combustion chamber (46) during the compression stroke performing step so as to ignite the conditioning fuel and the gaseous fuel. The gaseous fuel and the conditioning fuel are mixed in the combustion chamber (46) prior to the pilot fuel advancing step so as to facilitate ignition of the gaseous fuel in the combustion chamber (46).

    Abstract: A method for detecting and diagnosing a gaseous fuel leak in a dual fuel internal combustion engine system comprises producing a fault signal indicating that there is a leak of gaseous fuel into liquid fuel when an amount of gaseous fuel is detected in the liquid fuel return line through which liquid fuel is returned from the fuel injector to the fuel supply. The method can further comprise diagnosing a failure of the fuel injector or of at least one of the system components which regulate the gaseous fuel and the liquid fuel supply pressures by evaluating if an amount of gaseous fuel has been detected in the liquid fuel return line and calculating the pressure differential between the liquid fuel rail pressure and the gaseous fuel rail pressure.

    Abstract: A dual fuel engine (2) is provided which is supplied with diesel fuel and at least one secondary fuel, such as LPG. The engine (2) has a plurality of cylinders (4, 6, 8, 10) in which pistons reciprocate. Each cylinder has diesel injectors (4A ,6A, 8A, 10A) for injecting the diesel fuel into the cylinder during an appropriate stroke of the piston and an air inlet valve (4C, 6C, 8C, 10C) which opens during the appropriate stroke of the piston to permit air flow therethrough. Each cylinder is further provided with LPG injectors (4B, 6B, 8B, 10B) for injecting the secondary fuel into the cylinders. The LPG injectors are independent to and separate from the diesel fuel injectors. The LPG and diesel fuel injectors are also independently controlled.
