摘要:
An engine control system, for controlling an engine of a jet-propulsion boat, includes a cavitation-control-mode determination unit, which starts a cavitation-control mode when an engine speed not faster than 3200 rpm is maintained for a predetermined time period. During a normal sailing operation, ignition timing is set by a first ignition-timing setting unit. Upon detection of a cavitation-control-mode by the cavitation-control-mode determination unit, an engine speed is raised up to a speed not slower than 3200 rpm, which makes an ignition-timing switching unit to select a second ignition-timing setting unit. The second ignition-timing setting unit retards the ignition timing for the normal sailing operation when the engine speed becomes 6500 rpm or faster. In addition to retardation of the ignition timing, a boost pressure control command upper-limit value is switched to a value at a startup operation, which is less than a value at the normal sailing operation.
摘要(中):
用于控制喷射推进船的发动机的发动机控制系统包括空化控制模式确定单元,当预定时间段内保持不超过3200rpm的发动机转速时,开始空化控制模式。 在正常航行操作期间,通过第一点火正时设定单元设定点火正时。 当通过空化控制模式确定单元检测到空化控制模式时,将发动机转速提升到不低于3200rpm的速度,这使点火正时切换单元选择第二点火正时设置 单元。 当发动机转速为6500rpm或更快时,第二点火正时设定单元延迟正常航行操作的点火正时。 除了点火正时的延迟之外,将升压压力控制指令上限值切换为小于正常航行运转时的值的启动运转时的值。
