Abstract
The subject matter of this specification can be embodied in, among other things, a method performed in connection with an internal combustion engine, and the method including receiving a pressure signal from a combustion chamber pressure sensor during a first range of volumes, the first range corresponding to a portion of a compression phase, the received pressure being a first pressure, providing, based on the received pressure signal, a first pulse of fuel at a first position of the body during the compression phase, and providing, based on the received pressure signal a second pulse of fuel at a second position of the body during the compression phase.
Claims17
An apparatus for controlling operation of an internal combustion engine, the engine comprising a body sealed in a combustion chamber, the body being moveable to a top dead center position to compress at least one of a gas or a gas/liquid mixture in a compression phase and movable from the top dead center position by expanding combustion gasses in an expansion phase, each position of the body defining a volume of the combustion chamber, and the apparatus comprising:
- a processor to receive input from a position sensor configured to sense a position of the body corresponding to the volume of the combustion chamber and from a combustion chamber pressure sensor, the processor configured to:
- receive, during the compression phase, a pressure signal from the combustion chamber pressure sensor during a first range of volumes, the first range corresponding to a portion of the compression phase, the received pressure signal being representative of a first pressure;
- provide, during the compression phase and based on the received pressure signal received during the compression phase, a first signal configured to provide a first pulse of fuel at a first position of the body;
- and
- provide, during the compression phase and based on the received pressure signal received during the compression phase, a second signal configured to provide a second pulse of fuel at a second position of the body.
