  • Patent number: 10851738
    Abstract: A method of improving fuel delivery in an engine having one or more cylinders that are over-fueled related to other cylinders, such as a D-EGR engine. The fueling system uses a mechanical fuel pump, which is cam-driven. The cam has lobes corresponding to the desired displacement for each cylinder. The lobe corresponding to the over-fueled cylinder is shaped differently, such that the filling stroke of the pump is increased.

  • Patent number: 10837377
    Abstract: A method of implementing control logic of a compression ignition engine is provided. The engine includes an injector, a variable valve operating mechanism, an ignition plug, at least one sensor, and a processor. The processor outputs the signal to the ignition plug in a specific operating state so that unburnt mixture gas combusts by self ignition after the ignition plug ignites the mixture gas inside a combustion chamber. The method includes determining a geometric compression ratio ? of the engine, and determining control logic defining a valve opening angle CA of an intake valve. The valve opening angle CA (deg) is determined so that the following expression is satisfied, if the geometric compression ratio ? is ?<14, ?40?+800+D?CA?60??550+D. Here, D is a correction term according to the engine speed NE (rpm), D=3.3×10?10NE3?1.0×10?6NE2+7.0×10?4NE.

  • Patent number: 10753272
    Abstract: A supercharging system includes a first supercharger including a first compressor; a second supercharger including a second compressor provided downstream of the first compressor, and a controller controlling the first and second superchargers. At least one of the first and second superchargers includes an electric motor for driving the first or second compressor. At least one of the first and second superchargers includes a turbine, and a nozzle vane that adjusts a flow-path area of the exhaust gas flowing into the turbine. When a charge amount of a battery is low, the controller sets an upper limit of an output command value for the motor to be lower than when the charge amount is not low, or starts regenerative operation of the motor. A vane control part controls an opening degree of the nozzle vane so that the flow-path area decreases with a control of the electric motor.

  • Patent number: 10746093
    Abstract: Methods and systems are provided for indicating whether a wastegate positioned in a vehicle exhaust system is stuck in a closed or open configuration. In one example, a method comprises activating an electric air compressor positioned in an intake of the engine and obtaining a first baseline air flow and a second baseline air flow in the exhaust system, and in response to an indication that the wastegate is potentially stuck open or closed, obtaining a test air flow measurement via activating the electric air compressor and comparing the test air flow in the exhaust system to the first and/or the second baseline air flow. In this way, the wastegate may be diagnosed under conditions of limited engine operation, such as that which may occur in hybrid electric vehicles.

  • Patent number: 10738723
    Abstract: An internal-combustion engine includes: a supercharger; an EGR passage connecting between an exhaust passage and an intake passage downstream of the supercharger; a control device controlling EGR; and an intake pressure sensor that detects a supercharge pressure being a gas pressure in the intake passage downstream of the supercharger. A comparison-target pressure is a higher one of a target supercharge pressure and an actual supercharge pressure detected by the intake pressure sensor. The control device compares the comparison-target pressure with an exhaust gas pressure in the exhaust passage. When the comparison-target pressure is higher than the exhaust gas pressure, the EGR is prohibited and an EGR valve is fully closed. When the comparison-target pressure is lower than the exhaust gas pressure, the EGR is permitted.

    Abstract: A conduit connection assembly includes a first conduit part and a second conduit part, assembled to form a conduit connection delimiting a first fluid conducting volume from a second fluid conducting volume. The first and second fluid conducting volumes communicate with each other via a pressure change inducing device. During use of the conduit connection assembly, the pressure in the first conducting volume is higher than the pressure in the second conducting volume. A cavity is formed between the first and second conduit parts at a distance from the first fluid conducting volume, and a draining connection is adapted to provide a communication between the cavity and the second fluid conducting volume. A slot, formed by the assembly of the two conduit parts, provides a communication between the first fluid conducting volume and the cavity.
