Abstract
A method and apparatus for detecting non-contributing cylinders in a reciprocating engine is provided. An accelerometer is attached to the engine and configured to generate a signal corresponding to cylinders firing in the engine. By comparing waveforms generated by a signal processor, it can be determined if a cylinder is not firing and which cylinder is not firing.
Claims25
An apparatus for detecting a non-contributing cylinder in a reciprocating engine comprising:
- an accelerometer mounted to the engine, and configured to generate a signal corresponding to cylinders firing within the engine.
An apparatus for detecting a non-contributing cylinder in a reciprocating engine comprising:
- means mounted to the engine for detecting accelerations corresponding to cylinders firing in the engine and
- means for generating a first signal corresponding to cylinders firing within the engine.
A method of detecting a non-contributing cylinder in a reciprocating engine comprising:
- attaching an accelerometer to the engine;
- generating a first signal with the accelerometer;
- transmitting the signal to a signal processor;
- and
- analyzing an output from the signal processor corresponding to the signal.
