摘要： An oil control valve (60) that controls a variable valve timing gear for adjusting operation timing of at least one of exhaust and intake camshafts mounted on a cylinder head (1) of an internal combustion engine. The oil control valve comprises a housing (3) provided with plural oil lines; a spool type valve (5) that moves in the housing to open and close said oil lines; and a solenoid (31) having a metal case (33) that forms a part of a magnetic circuit and driving the spool type valve; and this housing (3) is mounted on the cylinder head (1) of said internal combustion engine. At least a part of the metal case (33) passes through a through hole (183) provided through a cylinder head cover (18) covering the cylinder head (1) and is disposed outside the cylinder head cover (18). As a result, all the essential part of the oil control valve (60) is disposed inside the head cover (18), and therefore space factor is improved. Even in case of oil leakage out of the solenoid (31), the oil flows in the head cover, and the oil does not leak out of the engine.

摘要： An engine has an engine body having an outer surface that defines an outer area next thereto. An air intake system has an intake valve movable between a closed position and an open position. An intake camshaft that actuates the intake valve extends through the engine body and toward the outer area beyond the outer surface. A drive mechanism drives the camshaft. A portion of the drive mechanism is disposed in the outer area. A hydraulically operated change mechanism changes an angular position of the camshaft relative to a crankshaft. A control valve unit controls the change mechanism. The control valve unit at least in part is disposed within the outer area.

摘要： A phaser for an internal combustion engine having at least one camshaft. The phaser has a housing and a rotor. The housing has an outer circumference for accepting a drive force and the rotor connects to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating chambers, advance and retard. The vane shifts the relative angular position of the housing and the rotor. The phaser also includes a spool valve comprising a spool slidably mounted within in a bore in the rotor. The spool routes operating fluid from a supply of pressurized fluid to the chambers. At least one passage from the supply to the chambers provides makeup fluid. The passage includes a check valve and a restrictor.

摘要： An improved arrangement for controlling the valve operation of an internal combustion engine wherein the control valves are mounted within perpendicularly extending bores formed in the cylinder head and camshaft bearing cap with the bores being deep enough so that the valves do not project significantly beyond the cylinder head. In addition, one or more of the connecting passages are formed by grooves in the mating surfaces of the cylinder head and bearing cap to avoid the necessity of drillings and particularly of drilling blind bores.

摘要： A pair of valve-timing controlling oil passages leading to a second valve-operating characteristic changing mechanism are defined in a lower camshaft holder, and a valve lift controlling oil passage leading to a first valve-operating characteristic changing mechanism is defined between the pair of valve-timing controlling oil passages in a mating surface of the lower camshaft holder with a cylinder head. In an area where the width of the valve lift controlling oil passage is reduced in order to avoid the interference with the valve-timing controlling oil passages, the depth of the valve lift controlling oil passage is larger than that in the other positions, whereby a sectional area of the oil passage is secured. Thus, the oil passages leading to the first and second mechanisms can be formed compact in a camshaft support member.

摘要： An outboard motor includes a cowling substantially enclosing a four-cycle engine therein. The engine has an air induction device for introducing air to a combustion chamber, and an exhaust system for communicating exhaust products away from the combustion chamber. A pair of camshafts actuate intake and exhaust valves. A variable valve timing (VVT) mechanism is arranged at an upper end of at least one of the camshafts to set the camshaft to an angular position between advanced and delayed angular positions. The cowling includes an air intake, and an engine cover is positioned between the engine and the air intake. The engine cover covers the top and sides of the VVT mechanism so as to protect the VVT mechanism from contact with water that may enter the cowling through the air intake.

摘要： A variable valve timing mechanism (VVT) for adjusting the valve timing of an intake valve of an internal combustion engine. The VVT has first and second pressure chambers for receiving oil. An oil control valve (OCV) is provided for controlling oil flow from a pump. Passages are provided for connecting the OCV to the pressure chambers to supply oil to the chambers in a controlled manner. A filter is located in the passage for filtering the oil. The filter is supported in water jacket where coolant flows. The filter is heated by the coolant to decrease the flow resistance of the oil.
