The map (4) indicates also a misfire area (22) and an operation point (23) of the engine in relation to the variables and the misfire condition.
Then, a misfire is indicated (517) when the combined acceleration signal exceeds the threshold (513).
A method for detecting misfire in a cylinder of an internal combustion engine through the ignition system of the engine.
A misfire determination device (205) provides a misfire indication (207) dependent on the selected acceleration signal (311).
A misfire indication (337) is provided dependent on a behavior of the fluctuations of air charge.
The control can also be used to energise a gas valve so as to provide fail-safe operation in the event of non-ignition.
Dynamic engine diagnostic devices are useful for detecting engine faults such as a misfiring cylinder during normal engine operation.
This improved support can offset certain stresses, such as radial stress RS that can be exerted against the insulator core nose when the engine experiences knocking or misfiring.
