用于内燃机的点火正时控制装置
摘要：
本发明公开用于内燃机的点火正时控制装置。对于包括缸内喷射器(11)和进气口喷射器(12)的内燃机，设置合适点火正时设定装置，用于根据从缸内喷射器喷射和从进气口喷射器喷射之间的燃料喷射比例来设定合适点火正时。当燃料喷射比例发生变化时，合适点火正时设定装置选择变化之前的合适点火正时值和变化之后的合适点火正时值中在延迟侧上的一个，并且在变化之后的至少预定的期间中将点火正时设定为所选择的合适点火正时值。
摘要（英）：

The invention discloses an ignition timing control apparatus for internal combustion engine. For an internal combustion engine including an in-cylinder injector (11) and an intake port injector (12), proper ignition timing setting means is provided for setting a proper ignition timing according to the fuel injection ratio between injection from the in-cylinder injector and injection from the intake port injector. When a change is made in the fuel injection ratio, the proper ignition timing setting means selects one of a proper ignition timing value before the change and a proper ignition timing value after the change that is on the retard side and sets the ignition timing at the selected proper ignition timing value in at least a predetermined period of time after the change.
