Abstract
A method of deriving the health of a first cylinder in a reciprocating device includes receiving a first signal from a first knock sensor in proximity to the first cylinder, receiving a second signal from a second knock sensor in proximity to a second cylinder, processing the first signal and the second signal, and deriving the health of the first cylinder by determining whether the first signal is coherent with the second signal.
Claims20
A method of deriving the health of a first cylinder in a reciprocating device, comprising:
- receiving a first signal from a first knock sensor in proximity to the first cylinder;
- receiving a second signal from a second knock sensor in proximity to a second cylinder;
- processing the first signal and the second signal;
- and
- deriving the health of the first cylinder by determining whether the first signal is coherent with the second signal.
A system, comprising:
- a controller configured to control a reciprocating engine, wherein the controller comprises a processor configured to:
- receive a first signal from a first knock sensor in proximity to a first cylinder;
- receive a second signal from a second knock sensor in proximity to a second cylinder;
- process the first signal and the second signal;
- and
- derive the health of the first cylinder by determining whether the first signal is coherent with the second signal.
A non-transitory computer readable medium comprising executable instructions that when executed cause a processor to:
- receive a first signal from a first knock sensor in proximity to a first cylinder;
- receive a second signal from a second knock sensor in proximity to a second cylinder, wherein the first cylinder is 360 crank angle degrees out of phase with the second cylinder;
- process the first signal and the second signal;
- and
- derive the health of the first cylinder comprising determining whether the first signal is coherent with the second signal.
