    摘要： The invention relates to systems enabling use of liquefied petroleum gas in diesel common-rail engines, and in particular to fueling diesel engines with diesel gas dual-fuel or only gas instead of diesel fuel. A gas ultrasonic transducer system for operating a diesel common-rail engine, comprises an electronic control unit; a water tank; a gas tank with gas supply shut-off valve; a gas level sensor; a gas pump operably connected with the gas tank; a water pump operably connected with the water tank; a mixer comprising a water level sensor and an ultrasonic transducer adapted to generate water vapor and gas mixture; wherein the mixer comprises two compartments: the upper compartment and the lower compartment, the means for separation of the upper and the lower compartments comprising an anti-reflux valve adapted to allow water vapor from the lower compartment to pass through the anti-reflux valve to the upper compartment and to prevent any liquid water from flowing into the upper compartment wherein the upper compartment of the mixer comprises an outlet operably connected with engine intake manifold; wherein the outlet of the gas pump is operably connected with the upper compartment of the mixer, the outlet of the water pump is operably connected with lower compartment of the mixer, where the ultrasonic transducer is located below the anti-reflux valve. The controlled interaction between elements of the system and vehicle elements results in a gas-water vapor mixture. In case of embodiment with dual fuel, the water gas mixture is calculated on the grounds of information received by the electronic control unit of the system from the engine common-rail, the engine temperature sensor, the air flow meter sensor, the acceleration pedal block.

    摘要： An internal combustion engine assembly is provided with a fuel tank for fuel including ethanol, and a reformer for steam reforming of ethanol that is with an outlet connected to a buffer tank. A first reformer supply duct extends from the fuel tank to the reformer via a fuel evaporator that is in heat exchanging contact with the exhaust gases, for supplying ethanol vapor to the reformer. A second reformer supply duct extends from a water reservoir to the reformer via a water evaporator that is in heat exchanging contact with the exhaust gases. The reformer is in heat exchanging contact with the catalytic converter and is adapted for reforming ethanol and water into syngas including carbon monoxide and hydrogen, and for supplying the syngas via the outlet to the buffer tank. The reformer and the catalytic converter may form an integrated unit.

    摘要： An air compression system includes an internal combustion engine operable to produce a power output in response to combustion of a fuel-air mixture, and an air compressor driven by the internal combustion engine and operable to draw in atmospheric air and discharge a mixed flow of compressed air and water. A water injection system supplies water to the fuel-air mixture and into the internal combustion engine, a separator assembly in communication with the air compressor separates a portion of the water from the compressed air, and a water passageway interconnects the separator assembly and the water injection system such that the air compressor supplies water to the water injection system.

    摘要： An internally cooled internal combustion piston engine and method of operating a piston engine is provided, with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. The effective compression ratio of the engines herein is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to the radiator, reduces engine knock, and reduces NOx emissions. The method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture allow for more complete and efficient combustion and therefore better thermal efficiency as compared to conventional engines.

    摘要： An exhaust gas line (1) of an internal combustion engine includes at least one catalytic converter (2) which is provided with at least one catalytic converter support (4) which is arranged in the housing (3) and which includes at least one first and one second area (5, 6) which can be flowed through in parallel, with the flow being capable of being deactivated in at least one area by a switching device (8) arranged in the exhaust gas line (1). In order to achieve a rapid activation of the catalytic converter in the simplest possible and most compact way, the areas (5, 6) of the catalytic converter support (4) have different physical and/or chemical properties in relation to response behavior, permeability, catalytic activity and/or thermal inertia.
