摘要： A fuel injection apparatus including a controller to output an injection time command signal and an opening movement time command signal to command an opening movement time from a closed state to an open state of an electromagnetic fuel injection valve and a control circuit, coupled to the controller, to change an electric current flowing in a coil of the electromagnetic fuel injection valve between when the electromagnetic fuel injection valve is closed and opened. The controller sends both the injection time command signal and the opening movement time command signal through the same signal line to the control circuit.

摘要： An electromagnetic fuel injection valve in an engine injects fuel by opening/closing a fuel flowing path with a valve element. A controller controls opening/closing of the fuel flowing path and changes magnetic force generated by a control coil driving the valve element so that the magnetic force is less during a valve open state-holding period than at an initial valve-opening time. The controller detects the voltage of a battery and applies the voltage fed from the battery to the control coil, while changing a time interval (Tc), for which current is passed through the control coil, based on the detected voltage, in order to change the magnetic force, without raising the voltage from the battery. The controller also detects increase/decrease of a pressing force on the valve element caused by fuel pressure and changes the time interval (Tc) accordingly.

摘要： A thermal type air flow measuring instrument is mounted to a main passage forming an intake air passage of an internal combustion engine and is provided with an auxiliary passage which includes a heating resistor and a temperature sensing resistor therein and an electronic circuit which is electrically connected to the heating resistor and the temperature sensing resistor. The auxiliary passage is a passage including at least one bent portion composed of a first path substantially parallel to the main passage and a second path having a path different in flow direction from the first path. A member forming the auxiliary passage is fixed in a united form to only a case member for interiorly protecting the electronic circuit, and the case member is fixed to the outer wall surface of the intake air passage. The auxiliary passage structure capable of being handled as a single module united to the case member is effective to the mass production of an air flow control system and the reduction in cost thereof since the structure can be mounted to different kinds of internal combustion engines.

摘要： An axial flow thermo-type air flow meter for internal combustion engines has a spider disposed in a main air passage formed in a body and having formed therein an auxiliary air flow passage including an axial auxiliary air flow passage portion accommodating a heat-generating resistor element for detecting a rate of engine intake air flow. The auxiliary air flow passage also includes more than one radial air flow passage portions which are connected to the axial air flow passage portion and curved and turned at their radially outer ends and then extend radially inwardly to outlet ends open to the main air passage, whereby the total length of the auxiliary air flow passage is increased to decrease the influence of pulsation of engine intake air flow on the air flow meter. Positioning of the outlet openings of the auxiliary air flow passage within a range of a radius from the axis of the main air flow passage, which radius is 1/2 of the radius of the main air flow passage, is effective to reduce fluctuation of the electric output of the air flow meter due to an unbalanced air flow velocity distribution occurring upstream of the air flow meter.

摘要： An air flow meter comprises a main passage for an axial main air flow; an axial subpassage for air flow, disposed in the main passage and formed so that part of the air in the main passage is taken in at an upstream side thereof and flows in the same direction as the axial main air flow; a radial subpassage for air flow, intersecting the axial subpassage at a downstream side of the axial subpassage so that air from the axial subpassage flows into the radial subpassage and is divided into two radial air flows running in different radial directions; the air having passed through the radial subpassage joining the axial main air flow. An air flow sensing means is disposed in the radial subpassage for sensing a flow rate of air therein, and a projection is disposed in the radial subpassage around the intersection of the axial and radial subpassages, for suppressing turbulence of air flow around the intersection.

摘要： A scroll type fluid machine having two scroll members each having an end plate and a spiral wrap formed on the end plate, the scroll members being coupled to each other such that the wraps thereof mate with each other. One of two scroll members being adapted to make an orbitary movement with respect to the other scroll member while being prevented from rotating around its own axis, so as to form at least one working chamber of different pressures between two scroll members. At least two pressing force imparting chambers are formed on the opposite side of the orbitary scroll member to the wrap. The pressing force imparting chambers includes a first chamber which is communicated through a communication passage with at least one of the working chambers which is not materially communicating with a low pressure port and is not at all communicating with a high pressure port of the machine, and a second chamber which is communicated with the high pressure port through a communication passage, so that fluid pressures of different levels are applied to the first and second pressing force imparting chambers so as to produce a force which presses the orbitary scroll member to the other scroll member.

It forms cavities, with small openings communicating them with the outside, on the inside of a tube, through three steps of forming a multiplicity of alternate grooves and ribs in parallel on the inner surface of the tube, forming cuts in the concentrically directed crests of the ribs, and then forcing the crests sidewise so that the crest of each rib is bent down onto an intermediate part of the adjacent rib to form a cavity in between.
