Abstract
A motorcycle having a system for combustion knock control. The motorcycle includes a spark generating circuit having a spark plug. The spark generating circuit produces a spark across a spark gap of the spark plug in response to a sparking signal. The motorcycle further includes an ion signal circuit that provides an ion signal indicative of an ion current being generated across the spark gap, and an analysis module electrically connected to the ion signal circuit and the spark generating circuit. The analysis module generates the sparking signal in a timed sequence, receives the ion signal from the ion signal generating circuit, measures a knock intensity within the ion signal, and modifies the timing sequence when knock is present.
