Spark ignition device for direct injection-type engines |
摘要 |
An ignition device sets a total discharge period, each discharge period and each intermittent period of a multiple discharge are set by a control map in addition to the setting of a throttle opening, fuel injection timing, fuel injection period and ignition timing for the range of non-stratified charge combustion, when a direct injection-type engine operates in the range of stratified charge combustion. Ignition signals including a plurality of rises and falls are outputted in time with a specific ignition timing after fuel injection. Thus a plurality of sparks are generated from the spark plug, ensuring reliable ignition in response to changes in the concentration of sprayed fuel within the operation range for stratified charge combustion.
