Abstract
A system for controlling combustion phasing in an internal combustion engine is provided that includes, but is not limited to a first sensor positioned within a first variable volume combustion chamber and a vibration sensor positioned outside of the first and second variable volume combustion chambers. A first signal from the first sensor is used to control the combustion process in the first variable volume combustion chamber and a combination of the first signal from the first sensor and the second signal from the vibration sensor is used to control the combustion process in the at least one second variable volume combustion chamber.

A method of controlling combustion phasing in an internal combustion engine comprising a first variable volume combustion chamber defined by a first piston reciprocating within a first cylinder, a second variable volume combustion chamber defined by a second piston reciprocating within a second cylinder, and a crankshaft coupled to and driven by a movement of the first piston and the second piston, comprising the steps of:
- sensing a first signal representative of a combustion process in the first variable volume combustion chamber;
- sensing a second signal representative of the combustion process in the first variable volume combustion chamber and the second variable volume combustion chamber;
- controlling the combustion process in the first variable volume combustion chamber based at least in part upon the first signal;
- and
- controlling the combustion process in the second variable volume combustion chamber based at least in part upon a combination of the first signal and the second signal.
A system for controlling combustion phasing in an internal combustion engine having a first variable volume combustion chamber defined by a first piston reciprocating within a first cylinder, a second variable volume combustion chamber defined by a second piston reciprocating within a second cylinder, and a crankshaft coupled to and driven by a movement of the first piston and the second pistons, the system comprising:
- a first sensor positioned within the first variable volume combustion chamber and adapted to provide a first signal representative of a combustion process in the first variable volume combustion chamber;
- a vibration sensor positioned outside of the first variable volume combustion chamber and the second variable volume combustion chamber and capable of providing a second signal representative of the combustion process in the first variable volume combustion chamber and the second variable volume combustion chamber;
- and
- a controller adapted to control the combustion process in the first variable volume combustion chamber using the first signal from the first sensor and adapted to control the combustion process in the second variable volume combustion chamber using a combination of the first signal from the first sensor and the second signal from the vibration sensor.
