  • Patent number: 10077744
    Abstract: A rich control for temporarily declining an air-fuel ratio of exhaust gas discharged from an engine combustion chamber is performed by an additional fuel being injected into a cylinder in an expansion stroke or an exhaust stroke in a state where a throttle opening degree is switched from a base throttle opening degree to a throttle opening degree for the rich control and an EGR rate is switched from a base EGR rate to an EGR rate for the rich control. The rich control is initiated by switching a low pressure side EGR control valve opening degree (VEGRL) to a low pressure side EGR control valve opening degree for the rich control (VEGRLR), then switching a high pressure side EGR control valve opening degree (VEGRH) to a high pressure side EGR control valve opening degree for the rich control (VEGRHR), then controlling the throttle opening degree (VTH), and then initiating the injection of the additional fuel (Qa).

  • Patent number: 10066539
    Abstract: A control unit controls a first power converter so as to make the speed of a motor/generator coincide with a prescribed speed command. A speed command (N*) set by an upper stream control system is inputted to a smoothing unit of the control unit. In the smoothing unit, the speed command (N*) is smoothed by a first-order lag element, and the rate of change is limited by a rate limiter to a prescribed value or less. For the speed command (Ns*) outputted from the smoothing unit, the difference (?N) from the actual speed (N) of the motor/generator is calculated in a difference calculator, a control command (S) based on this difference (?N) is generated in a control signal generator, and the first power converter is controlled on the basis of this control command (S). Fluctuations in the supply of power to the electric motor are thereby suppressed.

  • Patent number: 10066561
    Abstract: A method of controlling a rate of warm-up of an internal combustion engine fluidly connected to an exhaust system is disclosed. The method includes identifying a cold-start of the engine. The method also includes regulating, in response to the identified cold-start of the engine, an exhaust pressure modulation (EPM) valve arranged in a main exhaust passage of the exhaust system. The main exhaust passage channels engine exhaust gas to the ambient. Such regulation of the EPM valve will restrict a flow of the engine exhaust gas to the ambient and increase exhaust gas backpressure in the exhaust system up to a predetermined pressure value. Furthermore, the subject regulation of the EPM valve will increase a load on and the rate of warm-up of the engine. A vehicle having an engine and a controller programmed to control a rate of the engine's warm-up of according to the method is also disclosed.

  • Patent number: 10066541
    Abstract: Control techniques for a turbocharger of an engine utilize a wastegate valve configured to divert exhaust gas from a turbine of the turbocharger that is rotatably coupled to a compressor of the turbocharger. A controller is utilized to obtain a torque request for the engine, determine a target compressor power based on the engine torque request, determine a normalized target turbine power based on the target compressor power, determine a target position for the wastegate valve based on the normalized target turbine power and a normalized exhaust flow, and actuate the wastegate valve to the target position. Such control techniques involve the actual calculation of much less intermediate parameters, such as target turbine pressure ratio, which results in more efficient calibration and implementation.
