    Abstract: The present disclosure generally relates to a control system (50) configured to be used in a turbocharged internal combustion engine (10). The disclosed control system (50) may comprise an exhaust throttle valve (54) configured to be disposed downstream of a turbine (42) of a turbocharger and to control a flow of exhaust gas originating from at least one cylinder (26A to 26D). The disclosed control system (50) may further comprise a control unit (52) connected to the exhaust throttle valve (54) and configured to determine a differential pressure of the air/fuel-mixture across an intake throttle valve (27) disposed upstream of the at least one cylinder (26A to 26D), and, if the differential pressure exceeds a differential pressure threshold, adjust the exhaust throttle valve (54) such that the differential pressure of the air/fuel-mixture across the intake throttle valve (27) reduces.

    Abstract: A method of controlling a locomotive diesel engine using a three-component fuel mixture consisting of gaseous and liquid fuels and air in which the diesel is controlled by simultaneously changing the amount of gaseous and liquid fuels supplied to the cylinders, while the amount of air is determined by the amount of supplied fuels in such a way as to ensure that the excess air coefficient is maintained at a given range. As well as a locomotive diesel engine comprising a liquid fuel injection system, a gas fuel injection system and an air supply system to the cylinders, and a power control system which contains a throttle valve installed in the intake manifold.

    Abstract: A method for fuelling an internal combustion engine, and a fuel system for delivering a variety of fuel types to the engine, configured to accommodate liquid fuels such as gasoline, ethanol or a blend thereof, and gaseous fuels such as CNG, LNG or LPG. The engine is configured to operate on any of the designated liquid fuels, and can switch between the liquid and gaseous fuels. The fuel system includes a common delivery arrangement, for selectively delivering fuel into the combustion chamber of each cylinder of the engine, comprising a fluid delivery injector and a liquid metering device configured for operation in concert. The same common fluid delivery injector is used for delivery of gaseous fuel only, delivery of liquid fuel only (by way of an air assist delivery process), or delivery of a fuel mixture comprising the gaseous fuel and the liquid fuel.

    Abstract: During transition between operating modes on a dual fuel engine, when the engine switches from operating with one fuel to operating with another fuel, there has been the problem of maintaining engine torque within a predetermined range. An improved method for operating an internal combustion engine comprises selecting between operating in a liquid fuel mode with a liquid fuel and a dual fuel mode with a liquid fuel and a gaseous fuel; adjusting an air system to set-points associated with one of the dual fuel mode when transitioning to the dual fuel mode and the liquid fuel mode when transitioning to the liquid fuel mode, as a function of engine operating conditions; and adjusting at least one of liquid fuel injection quantity and liquid fuel injection timing in response to changes in the air system when transitioning to one of the dual fuel mode and the liquid fuel mode, as a function of engine operating conditions.

    Abstract: A fuel delivery system is disclosed which has a housing (3) having a chamber (310) in which an injector (20) is located. A liquid gas inlet (301) supplies liquid gas to chamber (310) so the liquid gas can in turn be supplied to the injector (20) for injection into a cylinder of an engine. A transfer tube (315) supplies liquid gas from the chamber (310) which is not ejected by the injector (20) to a vapour injector (313) which forms a regulator for regulating the pressure of the liquid gas and any vapour in the chamber (310). The use of the injector (313) as the pressure regulator overcomes problems associated with icing in the vicinity of the regulator which may otherwise impair proper operation of the regulator.
