Abstract
A system includes a control system configured to monitor operating conditions in at least a first cylinder of a reciprocating engine and to control the reciprocating engine, wherein the control system includes a first sensor configured to monitor a first type of operating condition of the first cylinder, and a controller communicatively coupled with the first sensor. The controller is configured to receive a first signal indicative of a first measurement of the first type of operating condition from the first sensor; analyze the first signal to detect a misfire condition in the first cylinder; derive an amount of residual gas in the first cylinder if the misfire condition is detected; and adjust control of the reciprocating engine based on the amount of residual gas.

A system, comprising:
- a control system configured to monitor operating conditions in at least a first cylinder of a reciprocating engine and to control the reciprocating engine, wherein the control system comprises:
- a first sensor configured to monitor a first type of operating condition of the first cylinder;
- a controller communicatively coupled with the first sensor, wherein the controller is configured to:
- receive a first signal indicative of a first measurement of the first type of operating condition from the first sensor;
- analyze the first signal to detect a misfire condition in the first cylinder;
- derive an amount of residual gas in the first cylinder if the misfire condition is detected;
- and
- adjust control of the reciprocating engine based on the amount of residual gas.
A method of controlling an engine, comprising:
- receiving a first signal indicative of a first measurement of a first type of operating condition from a first sensor, wherein the first sensor is configured to monitor a first type of operating condition of a first cylinder of a reciprocating engine;
- analyzing the first signal to detect a misfire condition in the first cylinder;
- deriving an amount of residual gas in the first cylinder if the misfire condition is detected;
- and
- adjusting control of the reciprocating engine based on the amount of residual gas.
A tangible, non-transitory computer readable medium comprising computer instructions stored thereon, the computer instructions, when executed by a processor, are configured to cause the processor to:
- receive a first signal indicative of a first measurement of a first type of operating condition from a first sensor, wherein the first sensor is configured to monitor a first type of operating condition of a first cylinder of a reciprocating engine;
- analyze the first signal to detect a misfire condition in the first cylinder;
- derive an amount of residual gas in the first cylinder if the misfire condition is detected;
- and
- adjust control of the reciprocating engine based on the amount of residual gas.
