摘要： PROBLEM TO BE SOLVED: To suppress erroneous determination of misfire of an internal combustion engine caused by damper slip in the internal combustion engine with an output shaft connected to a rear stage shaft on a rear stage through a damper with a torque limitter. SOLUTION: A rotational speed difference ΔN as a deviation between engine speed Ne calculated based on the crank angle of the engine and a damper rear stage rotational speed Nd as the rotational speed on the rear stage of the damper is calculated (S310). When the calculated rotational speed difference ΔN is compared with a threshold Nerf (Step S320) and the rotational speed difference ΔN is larger than the threshold Nref, it is determined that the damper slips (Step S330) and a determination result of misfire of the engine based on the crank angle used for determining slip is canceled (Step S340). Thereby, it is possible to suppress erroneous determination of the misfire of the engine caused by the damper slip with the torque limitter. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enable a physical quantity to be detected under a higher pressure in a physical quantity detection device.SOLUTION: A physical quantity detection device 1 includes a sensitive layer 12 for detecting a physical quantity provided on a bearing 22. On the sensitive layer 12, the physical quantity detection device includes further an oxide film 13 and a silicon nitride film 14 sequentially from the side of the sensitive layer 12. Since the silicon nitride film 14 is harder than the oxide film 13, by disposing the silicon nitride film 14 on the side coming into contact with an external member, the sensitive layer is hard to subject to damages. In a case of disposing the oxide film 13 between the silicon nitride film 14 and the sensitive layer 12, since film stress is lower in the oxide film 13 than in the silicon nitride film 14, force transmitted to the sensitive layer 12 can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a blow-by gas processing device capable of reducing oil mist in blow-by gas without increasing a pressure loss or a size of a filter element in an internal combustion engine.SOLUTION: Oil mist present around oil can be absorbed in the oil by intermolecular force while the oil sprayed to a blow-by gas passage 18 from an oil spraying part 22 falls, and the oil mist in blow-by gas can be thereby reduced. The diameter of the oil mist not fully removed is increased through the combination with the sprayed oil, so that the oil mist is then easily captured by a cyclone type oil separator 14. Accordingly, there is no need for reducing the mesh size of a filter element with an increase in pressure loss or for increasing the size of the filter element.
摘要翻译：要解决的问题：提供一种能够减少窜气中的油雾而不增加内燃机中的压力损失或过滤元件的尺寸的窜气处理装置。解决方案：存在于油罐周围的油雾通过分子间力被吸收在油中，同时从喷油部22喷射到窜气通道18的油下降，从而可以减少窜气中的油雾。通过与喷射油的组合，未完全除去的油雾的直径增加，因此油雾容易被旋风式油分离器14捕获。因此，不需要减小过滤器的筛网尺寸元件，其压力损失增加或用于增加过滤元件的尺寸。
