Abstract
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.
