摘要： PROBLEM TO BE SOLVED: To precisely measure the magnitude of a frictional force acting between the piston and the cylinder liner of an internal-combustion engine by a simple means by preventing an influence due to the pressure of a combustion chamber. SOLUTION: A circumferential groove 33 is formed at the outside of a part near the upper end part of a cylinder liner 3 and in an upper part from the position of the upper dead center of a top ring 82 at a piston 8, and a thin wall part is formed. In addition, strain gages 70a, 70b as the detecting means of the expansion and contraction amount in the direction of the central axis of the Thin wall part are pasted on the bottom face of the groove 33 which is substantially parallel to the central axis line of the cylinder liner 3. Even when the pressure of a combustion chamber 16 acts on the surface of a flange 31 at the cylinder liner 3, a frictional force acts substantially on the bottom face of the groove 33. As a result, as different from a conventional apparatus in which strain gages are pasted both on the surface and the rear surface of the flange 31 as a deformable part, an error due to the influence of the pressure of the combustion chamber is not generated in the detection value of the frictional force.

摘要： PURPOSE:To enable a high potential to jump up quickly in an ignition device using a piezo element by applying the offset to said piezo element using a GTO thyristor after the resonance phenomenon of the piezo element becomes stable. CONSTITUTION:Based on the respective outputs of a revolutional angle sensor 5, a suction pressure sensor 6, and a water temperature sensor 7, an ECU1 possesses various arithmetic operations to generate predetermined control signal. Using said control signal, the power transistors 21 and 22 inside an ignitor driving circuit 2 has the primary current of a transformer 24 switched to generate alternate voltage at the secondary side of a transformer 4. By applying this alternate voltage to the piezo element 31 of the ignitor 3, a high voltage is generated at the opposed ends of said ignitor to drive an ignition plug 4. Inside the ignitor 3, a GTO thyristor 32 is disposed between the output terminal of the piezo element and the earth. Said thyristor 32 is opened under control after the specified period passed from the point when the alternate voltage is applied to the piezo element 31.

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。
