摘要： A valve driving device of an engine under the present invention is provided with a cam shaft for exclusive use of intake for driving intake valves and a cam shaft for exclusive use of exhaust for driving exhaust valves. At least either the intake valve or the exhaust valve is pluralized and a transmitting member is trained between the cam shaft with more valves to drive and an engine output shaft. Gears to mesh with each other are provided on said two cam shafts. Under the above composition, only one pulley on the driven side or only one sprocket is required and therefore compactness of the engine can be realized. Also, rotation of the cam shaft having more valves to drive and large torque fluctuation can be stabilized and reliability of gears can be improved, without reinforcing the gears.

摘要： A multi-valve engine of the type having a line of cylinders, intake and exhaust camshafts, and rocker arms for operatively connecting valves to the camshafts includes a first valve group of three valves consisting of either intake valves or exhaust valves and a second valve group consisting of the other of either intake valves or exhaust valves. Each of the valves of the first valve group is oriented such that a valve stem thereof is inclined outwardly to one side of the line of cylinders, while each of the valve of the second valve group is oriented such that a valve stem thereof inclines outwardly to an opposite side of the line of cylinders. First hydraulic lash adjuster means for a centrally-located valve out of three valves of the first valve group is positioned closer to a bore center of the cylinder than the centrally-located valve, or on a delay side in the rotational direction of the camshaft. Second and third hydraulic lash adjuster means for side-located valves of the three valves of the first valve group are positioned farther from the bore center than the side-located valves, or on a leading side in the rotational direction of the camshaft.

摘要： In a V-type engine with two bore-offset banks opposed to one another at a predetermined angle, an accessory mechanism is provided between the two banks. A drive belt for the accessory mechanism is disposed on the side of one of the banks which is recessed inwardly due to the bore offset. In another embodiment, the accessory mechanism is a supercharger driven by a balancing shaft which, in turn, is driven by the crank shaft. In yet another embodiment, the V-type engine has a separate timing belt for each bank, that is, a first timing belt for the bank which is recessed inward because of the bore offset, and a second timing belt for the bank which juts out because of the bore offset. A drive belt is provided for driving the supercharger. The belts are arranged in the following order from the inside outward: the second timing belt, the first timing belt and the accessory belt.

摘要： An intake system, for use with an internal combustion engine having a plurality of intake valves for each cylinder, includes a plurality of intake ports, opening into the combustion chamber side of the internal combustion engine at different distances from a spark plug of the cylinder. The intake valves are controlled to keep an intake port located at the shortest distance from the spark plug opened only slightly in an early intake cycle stage while opening the other intake ports at their desired timings. The intake port located at the shortest distance from the spark plug is subsequently opened at a desired timing, thereby aspirating a substantial quantity of air through the closest intake port at a later time than through the other intake ports.

摘要： Engine valve driving apparatus including a camshaft rotatable with a crankshaft of the engine with a movable cam member supported in sliding fit by the camshaft for axial movement but prevented from any rotation relative to the camshaft. An engine valve is driven by the movable cam member, and a hydraulic system axially shifts the movable cam member between an operative position where the movable cam member is brought into cooperation with the engine valve and an inoperative position where the movable cam member is completely out of cooperation with the engine valve. The hydraulic system causes the shifting movement of the movable cam member according to engine operating conditions so that the engine valve is driven at different speeds or different timings.

摘要： A valve operating system for an engine includes a cam shaft and first and second cams, mounted on the cam shaft, which are selectively utilized to provide different valve opening characteristics in accordance with a vehicle operating condition. A first rocker arm follows the first cam and engages a valve stem of a valve to operate the valve, and a second rocker arm follows the second cam at a position not interfering with the valve stem. A connecting device connects the first and second rocker arms so that they move together, and a control device controls the connecting means to connect the first and second rockers in accordance with the vehicle operating condition so that the valve opening characteristic is defined by a cam profile of the second cam which is larger than that of the first cam. When the first and second rocker arms are engaged with each other, the valve opening period is increased to reduce pumping loss in the engine under relatively low engine load.

摘要： A cylinder head for a double overhead camshaft engine, with a plurality of intake valves and a plurality of exhaust valves for each cylinder, is covered by a cylinder head cover to support, for rotation, intake and exhaust camshafts. A hermetically sealed chamber, formed between the cylinder head and head cover as an oil jacket, is divided into two chambers, enclosing major parts of the intake and exhaust camshafts, respectively, which are in communication with each other near first ends of the chambers. An outlet hole is formed in the cylinder head cover so as to permit blow-by gas to flow out of the chamber. A cover, covering a gear train for operationally coupling the intake and exhaust camshafts, is bolted to one end of the head cover at several points around the gear train and to the cylinder head.
