摘要： 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.

摘要： A motorcycle including a two-cylinder engine. The engine includes a housing, first and second cylinders having first and second combustion chambers, respectively, and first and second pistons reciprocating in the first and second chambers, respectively. The motorcycle further includes a spark generating circuit including a spark plug having a spark gap exposed to the first combustion chamber, an ion sensing circuit including the spark plug and being operable to generate an ion signal indicative of an ion current generated across the spark gap, and an analysis module coupled to the ion signal circuit. The analysis module is operable to receive the ion signal and to analyze the ion signal to determine whether a no-combustion event occurs in the first cylinder. The analysis module may be further operable to determine if the spark generating circuit has an intermittent connection.
