  • Patent number: 10151353
    Abstract: A mechanical clutch such as a dog clutch includes a plurality of balls or rollers disposed in a carrier and positioned between opposed sets of straight cut teeth extending from opposed drive and driven elements. A ball or roller is positioned between each adjacent pair of teeth such that the torque load is transferred from the tooth on a first or drive element, through the ball or roller, to an adjacent projection or tooth on a second or driven element. The balls or rollers are maintained in position by the carrier having an inner ring and a concentric outer ring. Greatly reduced disengagement force, even under load, is exhibited by a clutch of this configuration.

The method includes outputting a control signal to move the valve to a first position in which the exhaust gas stream flows through a first portion of the first after treatment device or a second position in which the exhaust gas stream flows through a second portion of the first after treatment device based on the temperature.

    Abstract: Fuel vapor temporary storage device includes a collecting tank which is configured to collect fuel and a temporary storage device is configured to collect gas-phase components that are released from fuel located in the collecting tank. A compressor is configured to supply compressed air to the device. A first line creates a fluid connection between the collecting tank and the temporary storage device. A second line creates a fluid connection between the compressor and the temporary storage device. The temporary storage device receives the gas-phase component via the first line and receives compressed air from the compressor via the second line. The temporary storage device has a third line configured to discharge the collected gas-phase components from the temporary storage device to an internal combustion engine when the compressor is supplying compressed air via the second line.

    Abstract: A method and system controls a regeneration of a particle filter of an internal combustion engine. A first value is measured for the oxygen content in exhaust gas upstream from the particle filter. A second value is measured for the oxygen content in exhaust gas downstream from the particle filter. The particle filter is determined to be free of soot when the second value for the oxygen content is equal to the first value for the oxygen content.

  • Patent number: 10145284
    Abstract: An automotive vehicle includes an internal combustion engine and an exhaust system. The exhaust treatment system includes a dosing system that injects NH3 into an exhaust gas stream generated by the engine. An SCR device stores an amount of the NH3 and converts NOx into diatomic nitrogen (N2) and water (H2O) based on the stored amount of the NH3. The vehicle further includes an SCR status estimator device and a controller. The SCR status estimator device determines an NH3 coverage ratio (R), which indicates a stored amount of NH3 with respect to a maximum NH3 storage capacity of the SCR device. The controller determines a target NOx reduction efficiency (?NOx) of the SCR device, and an NH3 coverage ratio set point (Rsp) based on the ?NOx. The controller also generates an NH3 control signal (u) that controls the dosing system based on a comparison between the R and the Rsp.
