Control system for internal combustion engines |
摘要 |
<p>A control system for an internal combustion engine determines ignition timing of the engine and generates an ignition command signal to generate high voltage for discharging a spark plug provided for each cylinder of the engine. The control system detects sparking voltage generated across the spark plug when the high voltage is generated. The control system measures a duration over which the sparking voltage across the spark plug exceeds a predetermined reference value, after generation of the ignition command signal. According to a first aspect of the invention, the control system detects combustion roughness based on the duration measured. According to a second aspect of the invention, the control means detects an air-fuel ratio of an air-fuel mixture supplied to the engine, based on the duration measured.</p> |
