Abstract: A flow rate measuring device measures a flow rate of a main flow flowing through a duct. The flow rate measuring device includes a bypass passage, a flow rate sensor, and a measurement body. The measurement body includes a measurement flow inlet opening toward an upstream side of the duct and a cylindrical portion opening toward a downstream side of the duct. The cylindrical portion is disposed to cover the measurement flow outlet. The cylindrical portion includes an outer circumferential surface guiding the main flow and an inner circumferential surface guiding the measurement flow. The cylindrical portion includes a waveform portion formed in an edge side of an opening of the cylindrical. The waveform portion divides the main flow guided by the cylindrical portion into a plurality of main flows and divides the measurement flow guided by the cylindrical portion into a plurality of measurement flows.

Abstract: A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.

Abstract: A control system for an internal combustion engine has an intake valve, an exhaust valve, and an exhaust purifying catalyst that purifies exhaust gas after combustion of a fuel. During a fuel cut in which no fuel is supplied, a closing timing of the intake valve is controlled to a delayed angle side more than at a timing when the fuel is supplied and to a delayed angle side more than at a timing at a bottom dead center of an intake stroke, and an opening timing of the exhaust valve is controlled to an advanced angle side more than at the timing when the fuel is supplied and to an advanced angle side more than at the timing at the bottom dead center of an expansion stroke.

Abstract: In a solenoid of a hydraulic pressure control apparatus, a region adjacent to an oil flow guide portion of a stopper breathing passage is formed in a magnetism application region, through which a leakage magnetic flux leaking from a magnetic circuit at a time of turning on of a coil passes. Thereby, magnetic foreign objects made of iron or iron containing material are magnetically attracted to the leakage magnetic flux, so that intrusion of the foreign objects from an outside of the solenoid into a second volume variable chamber through the stopper breathing passage is limited.

Abstract: A sealing structure has a permanent magnet and a magnetic-flux guiding member for guiding magnetic flux of the permanent magnet to a brake shaft of a brake rotating member. The magnetic-flux guiding member surrounds an outer periphery of the brake shaft so as to form a sealing gap around the brake shaft. The sealing gap is communicated to a fluid chamber, in which magnetic viscous fluid is filled. A fluid sealing member is provided at the brake shaft at a housing outer side of the magnetic-flux guiding member to form an intermediate fluid chamber, in which an intermediate fluid made of non-magnetic liquid is filled.

Abstract: A power transmission system transmits power from an internal combustion engine to a first and a second auxiliary device through an endless transmitting member. Prior to issuing of an engine start request, the first auxiliary device is actuated to move a tensioner pulley to a given position to increase the degree of tension of the endless transmitting member. The actuation of the first auxiliary device as an engine starter upon the issuing of the engine start request, therefore, enables a drive shaft of the engine to be rotated immediately within a required time to crank the engine. This achieves a quick start of the engine and results in a decrease in amount of time between the issuing of the engine start request and the actual start of the engine.

Abstract: A valve timing control apparatus includes a temperature sensing member which expands at a main lock phase when a temperature of an engine is higher than or equal to a predetermined temperature so as to prohibit a main lock component from moving out of a main lock hole to a guide slot. The temperature sensing member shrinks at the main lock phase when the temperature of the engine is lower than the predetermined temperature so as to allow the main lock component to move out of the main lock hole toward the guide slot.

Abstract: When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve is switched to a locking mode after the camshaft phase is controlled to a lock phase, and a lock pin is moved to a lock position. The camshaft phase is locked at the lock phase, and timing advance and timing retard chambers communicate with each other through a back space. In this state, a locking time filling control is executed. In the locking time filling control, the control mode of a hydraulic control valve is switched to a filling mode, the hydraulic oil is supplied to a timing advance chamber, both of the timing advance chamber and the timing retard chamber are filled with the hydraulic oil, the back space is filled with the hydraulic oil, and thereafter the control mode of the hydraulic control valve is returned to the locking mode.

Abstract: A main lock member is fitted in a main lock bore at a main lock phase for closing an intake valve at a timing later than a timing when a piston reaches a bottom dead center, whereby a rotation phase is locked. In a subordinate lock mechanism, the rotation phase is locked at a subordinate lock phase advancing further than the main lock phase. In a lock control mechanism, a temperature sensing body is changed to an expanded state, whereby a moving member is latched at a first position in which the main lock member is allowed to be fitted in the main lock bore, whereas at a main lock phase in a cold stop state after a timing when the temperature of the stopped internal combustion engine becomes less than a preset temperature, the temperature sensing body is changed to a contracted state.

Abstract: A valve timing controller includes a lock mechanism that locks a rotation phase at a main lock phase when an internal combustion engine is started with an ambient temperature more than or equal to a preset temperature. The main lock phase represents a rotation phase set for closing an intake valve at a later timing later than a timing when a piston reaches a bottom dead center of a cylinder in the internal combustion engine. The lock mechanism locks the rotation phase at a sub lock phase representing a rotation phase advanced rather than the main lock phase in the internal combustion engine when the internal combustion engine is started with an ambient temperature lower than the present temperature.
