摘要:
A powertrain is provided having an engine operable in a reverse direction so that a reverse mode is provided through an electrically variable transmission without relying on pure electric or series electric operation, and without the addition of a dedicated reverse gear. A method of controlling such a powertrain is also provided.

A lubrication control system includes an accumulator to store oil. The accumulator can be filled with oil during operation of an engine. A control valve can be selectively operated to allow oil stored in the accumulator to flow to a turbocharger. At least one control module can control operation of a hybrid electric vehicle and determine an operating condition of the engine and command the control valve to open and close based on the operating condition.

A vehicle includes a vehicle body, a first motor disposed within the vehicle body, a second motor disposed within the vehicle body, and an engine removably disposed on the vehicle body and configured to selectively provide torque to the first motor when disposed on the vehicle body. A climate control compressor is disposed within the vehicle body and is selectively coupled to the first motor. A controller is configured to control the coupling of the climate control compressor to the first motor and to control the coupling of the engine to the first motor. The first motor is configured to generate electrical energy to operate the second motor when coupled to the engine. The controller is further configured to control operation of the engine.

An electric motor assembly includes a stator having a first set of electrical windings. The motor assembly includes a rotor assembly rotatable about an axis of rotation and that has a rotor with first and second rotor segments. Each of the rotor segments has a respective set of magnets spaced therearound. The motor assembly has a phaser that includes a phaser actuator and a phaser gear mechanism. The phaser gear mechanism has a plurality of members. The phaser actuator and the first and second rotor segments are each operatively connected to a different respective one of the members. The phaser actuator is activatable to change an angular position of the member to which the phaser actuator is operatively connected, moving one of the rotor segments about the axis of rotation relative to the other of the rotor segments to reduce back electromotive force in the first set of stator windings.

A hybrid powertrain is provided including an internal combustion engine sufficiently configured for operation in a homogeneous charge compression ignition mode of operation. An electric motor and an electric storage device are provided in parallel hybrid combination with the internal combustion engine. A transmission is operatively connected to the internal combustion engine and the electric motor. The engine may operate in one of a two-stroke and a four-stroke cycle.
摘要:
An internal combustion engine's start-up torsional disturbances are reduced by drawing down intake manifold pressure prior to engine cranking. In a preferred arrangement, a secondary air injection reaction pump is adapted for evacuating the intake manifold to effect the desired draw down of the intake manifold pressure.

An electric motor assembly includes a rotor hub, and a rotor supported on the rotor hub. The rotor hub has first and second hub portions, and the rotor has first and second annular rotor segments supported for rotation on the respective first and second hub portions. Each of the rotor segments has a respective set of magnets spaced circumferentially therearound. The rotor hub and the rotor segments are configured so that at least one of the rotor segments moves about the axis of rotation relative to the other of the rotor segments as the rotor hub rotates. The movement of the at least one of the rotor segments is an amount that increases as the speed of the rotor hub increases to reduce back electromotive force. The movement may be due to centrifugal force, which increases as speed increases, without requiring a control system to effect the movement.
