Abstract

A method and apparatus for starting an internal combustion engine is disclosed. A motor is mechanically coupled to the engine, the engine having at least one moveable element mounted in a chamber, the moveable element being operable to cause a changing compression condition within the chamber and being mechanically coupled to a shaft for generating mechanical power. The method involves causing the motor to supply a positioning torque to the engine to move the at least one moveable element into a starting position, The method also involves causing the motor to supply a starting torque to the engine when the at least one moveable element is in the starting position to cause the moveable element to accelerate from the starting position under low compression conditions to generate sufficient momentum to overcome a peak compression condition in the chamber, thereby reducing the starting torque required to start the engine.

Abstract

A method and apparatus for starting an engine in a hybrid vehicle being driven by an electric motor is disclosed. The motor is operably configured to deliver mechanical power through an automatic transmission to at least one vehicle drive wheel to cause an acceleration of the vehicle. The method involves coupling the engine to the motor to cause an inertial load on the motor thus causing the motor to decelerate to a reduced rotational speed to provide a starting torque to the engine for starting the engine, and causing the automatic transmission to change gear ratio to a target gear ratio associated with the reduced rotational speed while causing the motor to decelerate, the motor being operable to deliver increased torque at the reduced rotational speed, thereby generally maintaining the acceleration of the vehicle.

Abstract

A method and apparatus for managing power in a hybrid vehicle is disclosed. The vehicle includes an engine, an electric motor, and an energy storage element coupled to the motor. The method involves receiving a request to supply operating power to drive the vehicle and responding to the request by selecting an apportionment of operating power between the engine and the motor from among a plurality of apportionments having respective operating costs such that the selected apportionment is associated with a minimum operating cost, the operating cost including at least an engine fuel consumption cost and a storage element lifetime cost. The method further involves causing power to be supplied by at least one of the engine and the motor in accordance with the selected apportionment.

Abstract

A process and apparatus for reducing nitrogen oxide emissions in a genset comprising an engine and a generator and a shaft coupled to the engine and generator. The apparatus directs the generator to reduce load on the shaft while directing the engine to seek a steady state shaft speed for a desired energy transfer to the shaft when a shaft speed correction signal representing a shaft speed correction to reach the desired energy transfer meets a criterion.
