    Abstract: A variable camshaft timing phaser having a locking pin directly influenced by engine oil, which is not impacted by any intervening valves. The locking pin is comprised of a tapered pin, which fits into a tapered recess. The locking pin is biased towards engaging by a spring, and is retracted by oil from the engine oil supply. The locking pin remains disengaged from the tapered recess as long as the oil pump is on.

    Abstract: An improved four stroke engine for outboard motor having a protective cowling encircling the engine. The four stroke engine has V-shaped banks of cylinders and each bank is provided with a couple of overhead camshafts extending generally vertically. The engine has also a single crankshaft extending generally vertically. The crankshaft has a driving wheel, while each camshaft positioned on the inside of each bank has a driven wheel, which diameter is twice as large as the diameter of the driving wheel. The driven wheels on the camshafts are driven by an endless transmitter wound around the driving wheel and the driven wheels. The other camshafts of the respective banks are driven by the camshafts, which are directly driven by the crankshaft, with drive mechanisms. In another embodiment, both of the camshafts of the respective banks are driven by a couple of intermediate shafts and driven wheels placed on them. The driven wheels on the intermediate shafts are driven by the driving wheel on the crankshaft.

    Abstract: A valve-operating mechanism includes cam followers carried on an engine body 1 with their tip ends being in sliding contact with the cam, rocker arms integrally connected to the cam followers and carried on the engine body coaxially with said cam followers with their tip ends being connected to valves, and valve springs for biasing the valves in closing directions. In the valve-operating mechanism, auxiliary springs are connected to the cam followers for biasing and turning the cam followers in the same directions as directions in which the valve springs bias and turn the rocker arms through the valves. Thus, a couple of forces generated over the axis of the cam follower and the rocker arm due to biasing force of the valve spring can be offset in a valve-closing process.

    Abstract: A valve timing transmission apparatus is disclosed that increases the freedom of attachment positions for a pivot pin supporting a one end of timing chain and enables arrangement of a chain tensioner in an optimum position for tensioning of the timing chain. An opening having a diameter greater than a sprocket is provided on the drive sprocket side of an outer side wall of a timing chamber which is formed in one side wall of an engine main body and which accommodates the timing chain. A lid plate is removably secured to the engine main body so as to close the opening. Support bosses supporting both ends of the pivot pin are formed in opposite walls of the engine main body and the lid plate.

    Abstract: To reduce the noise caused by torsional reversals of a rotor hitting the phaser housing in a VCT cam timing system. A cam torque actuated phaser (phaser with check valves) the control loop is opened and rather then moving the spool valve to one end or the other end, the spool valve is moved just slightly off null. By doing this the oil ports in the spool passageways that control the motion of the phaser are restricted and the motion of the phaser is reduced. Therefore the noise of the phaser is reduced.

    Abstract: A line of small internal combustion engines, including twin cylinder engines and single cylinder engines. The engines each include a crankcase, and one or more cylinder members attached to the crankcase, the cylinder members being separate components from the crankcase. A number of different crankcases are provided for various types of single and two cylinder engines, the crankcases having common mounting structure to which the cylinder members may be attached. Thus, the manner in which the cylinder members are attached to the crankcases is the same for each of the different types of crankcases. Two different types of cylinder members are provided, one having a side valve or nullL-headnull valve train, and the other having an overhead cam (nullOHVnull) valve train. The cylinder members are therefore modular components which may be selectively used in a variety of different types of engines.

    Abstract: In a variable intake-valve operating system for an engine enabling a working angle of an intake valve and a phase at a maximum lift point of the intake valve to be varied, a variable working-angle control mechanism is provided to continuously change the working angle of the intake valve and a variable phase control mechanism is provided to continuously change the phase of the intake valve. A control unit is configured to be electronically connected to both the two variable control mechanisms, to simultaneously control these control mechanisms responsively to a desired working angle and a desired phase both based on an engine operating condition. The control unit executes a synchronous control that a time rate of change of the working angle and a time rate of change of the phase are synchronized with each other in a transient state that the engine operating condition changes.
