摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjustment device that prevents an unlocking failure of a vane rotor due to an operation failure of a stopper pin at the start of an engine.SOLUTION: The valve timing adjustment device restrains a housing and the vane rotor by engaging the stopper pin stored in a storage hole of the vane rotor with an engagement hole of the housing at engine start-up. After the engine start-up, an ECU inputs to a hydraulic control valve, a holding duty ratio at which hydraulic fluids of the same pressure are supplied to an advance angle chamber and a delay angle chamber (S106). It is determined whether the time needed for 720° rotation of a crankshaft has passed after the time when the holding duty ratio is input (S107). In the time, the direction of combined torque of advance angle hydraulic torque, delay angle hydraulic torque, and cam torque acting on the vane rotor becomes a delay angle direction, so that the stopper pin and engagement hole do not come in contact with each other.

摘要： PROBLEM TO BE SOLVED: To provide an actuator with rotation/linear motion conversion mechanism configured to prevent a nut from being rotated by vibration during transportation without increasing rotational resistance of the nut when a variable valve mechanism is driven.SOLUTION: One or both of an outer circumferential surface 16a of a nut 16 and an inner circumferential surface 10c of an inner race 10b of a bearing 10 is subjected to frictional coefficient reduction treatment, to reduce rotational force to be generated in the nut 16 due to vibration. Even if vibration is applied to the actuator during transportation before embedded in an internal combustion engine, the rotation of the nut 16 is prevented. A change in stroke of a sun shaft can be reliably prevented in the actuator, thereby maintaining excellent assemblability with respect to the internal combustion engine without reducing assembling accuracy. The frictional coefficient reduction treatment does not increase frictional force between a housing 4 and the nut 16, thereby preventing an increase in rotational resistance when the nut 16 is driven by an electric motor, then preventing reduction in fuel economy of the internal combustion engine.
摘要翻译：要解决的问题：提供具有旋转/线性运动转换机构的致动器，其构造成在运输期间防止螺母被振动旋转，同时在增加可变气门机构的驱动时螺母的旋转阻力的增加。解决方案：一个或两个螺母16的外周面16a和轴承10的内圈10b的内周面10c经受摩擦系数降低处理，以减少由于振动而在螺母16中产生的旋转力。即使在嵌入内燃机中之前在运输过程中对致动器施加振动，也能够防止螺母16的转动。在致动器中可以可靠地防止太阳轴的行程变化，从而在不降低组装精度的情况下保持相对于内燃机的优异的组装性。摩擦系数降低处理不会增加壳体4和螺母16之间的摩擦力，从而防止当电动机驱动螺母16时的旋转阻力的增加，从而防止内燃机的燃料经济性降低。

摘要： PROBLEM TO BE SOLVED: To provide a process different from a conventional process in a control to suppress the deviations of intake air amounts between cylinders by handling the variations of valve lift amounts and valve timing angles of an intake valve. SOLUTION: For the variations of intake air between cylinders Sd more than a reference value Krg ("YES" in S154), an average intake flow speed at the intake valve is made to be less than 0.85 times the sound speed by setting a valve lift amount VLAx for use in reducing average intake flow speed that is larger than usually set valve lift amount at a target valve lift amount (S156). Thereby, the compensation of the variations of intake air amounts is designed to be made to a certain degree by making shorter the period during which changes in average flow speeds are restricted by the sound speed. Thus, the variations of intake air amounts between cylinders are suppressed, and the selection of the control can be extended. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel feeding device of an internal combustion engine for liquefied petroleum gas capable of assuring always stable attenuation effects on the pulsation of the fuel pressure even when the fuel pressure largely varies, and capable of preventing variation of the injection quantity and generation of noise caused by the pulsation.
SOLUTION: In the fuel feeding device of the internal combustion engine for liquefied petroleum gas, the liquefied petroleum gas inside a fuel tank liquefied with pressure is fed to a delivery pipe 34, and pressed with a constant differential pressure relative to the fuel tank pressure to be injected by an injector 38. The fuel feeding device has a pulsation attenuator 50 for attenuating the pulsation of the fuel fed to the delivery pipe 34. The pressure of a return passage 37 is guided into a second pressure chamber 53 of the pulsation attenuator 50 from the junction A through a passage 59, so that the pressure difference between both sides of a diaphragm 51 is kept nearly constant. Therefore, even when the fuel pressure applied to a pressure chamber 52 largely varies, the diaphragm 51 is moved according to the variation and the pulsation of the fuel pressure is stably attenuated.
