摘要： PROBLEM TO BE SOLVED: To provide an ignition timing controller for an internal combustion engine to derive the cause of combustion fluctuation from various types of mechanical vibration observed in the internal combustion engine so as to be reflected on, the knocking control. SOLUTION: A timing T1 at maximum amplitude of vibration when the ignition timing is advanced at the angle Δt is compared with a timing Tt-1 at maximum amplitude before advancing in step 106. When the maximum amplitude position after advancing varies in synchronization with the advancing of the ignition timing, that is, the difference of the maximum amplitude timings before and after advancing is the value of advancing or greater (T1 +Δt =t-1 ), it is determined as a non-knocking state.

摘要： PROBLEM TO BE SOLVED: To improve an oil circulation from a thrust side and an anti-thrust side to intermediate phase positions thereof, between an inner circumferential surface of a cylinder and an outer peripheral surface of a piston in an internal combustion engine.SOLUTION: In an oil ring groove 22 of the piston 2, oil return holes 28, 30, 32, 34, 36, 38 are opened to a front side and a rear-side, and are not opened to the thrust side and the anti-thrust side. Accordingly, the highly pressurized oil at the thrust side and the anti-thrust side enters the oil ring groove 22 and promptly flows to the front side and the rear-side where the oil return holes 28-38 are present. Consequently, the oil can be supplied enough to the phase where the oil is insufficient, and thereby the oil circulation being a problem can be improved. The oil spreads enough in a circumference and has a superior lubrication effect, thereby effectively reducing friction in the internal combustion engine.
摘要翻译：要解决的问题：为了改善从推力侧和抗推力侧到中间相位置的油循环，在缸内的内周面与内燃机的活塞的外周面之间。解决方案：在活塞2的油环槽22中，油回流孔28,30,32,34,36,38向前侧和后侧开口，并且不向推力侧开放和反推力侧。因此，推力侧和防推力侧的高压油进入油环槽22，并迅速流向存在油回流孔28-38的前侧和后侧。因此，可以将油充分供给到油不足的相，从而可以提高油循环问题。油在圆周上扩散足够，具有优异的润滑效果，从而有效地减少了内燃机的摩擦。版权所有（C）2012，JPO＆INPIT
