摘要： A system for determining engine phase in a motorcycle engine includes a crank gear sensor mounted near the crank gear of the engine, a pressure sensor mounted on the air intake manifold of the engine, and a processor communicating with the crank gear sensor and the pressure sensor. First and second groups of crank gear teeth pass by the crank gear sensor before either of the first and second pistons of the engine reaches TDC. At low rpm, such as at start up, the processor determines the phase of the engine during a single rotation of the crankshaft by measuring and comparing the time periods taken by the groups of teeth to pass by the crank gear sensor. At high rpm, the processor determines the phase of the engine using the pressure sensor.

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.

摘要： A system for determining engine phase in a motorcycle engine includes a crank gear sensor mounted near the crank gear of the engine, a pressure sensor mounted on the air intake manifold of the engine, and a processor communicating with the crank gear sensor and the pressure sensor. First and second groups of crank gear teeth pass by the crank gear sensor before either of the first and second pistons of the engine reaches TDC. A third group of crank gear teeth passes by the crank gear sensor before the first piston reaches TDC, but after the second piston reaches TDC. At low rpm, such as at start up, the processor determines the phase of the engine during a single rotation of the crankshaft by measuring and comparing the time periods taken by the group of teeth to pass by the crank gear sensor. At high rpm, the processor determines the phase of the engine using the pressure sensor.
