Title:
燃焼診断システムを備えたモーターサイクル
Document Type and Number:
Japanese Patent JP4990238
Kind Code:
B2
Abstract:
A spark generating circuit includes a spark plug with a spark gap exposed to the first combustion chamber. An ion sensing circuit includes the spark plug and generates an ion signal indicative of an ion current generated across the spark gap. An integrator receives the ion signal and generates a diagnostic voltage, which is analyzed by a microprocessor to determine whether a no-combustion event occurred in the first cylinder. Independent claims are included for: (1) a method of determining whether a no-combustion event occurred in a two-cylinder engine of a motorcycle; and (2) a method of determining whether a spark generating circuit of a vehicle has an intermittent connection.
