摘要： A double overhead camshaft engine having two camshafts rotatably supported by a cylinder head. This two camshafts are drivably connected through an idler gear with a crankshaft of the engine by means of drive chains. The idler gear is rotatably mounted on an idler gear installation bolt which is fixedly secured only to a front end section of the cylinder head in a so-called cantilever arrangement. A surrounding wall structure for the idler gear is formed integral with the front end section of the cylinder head and extends in the direction of axis of the idler gear over the idler gear to form a front end section. An opening is formed at the surrounding wall structrure front end section and located on an opposite side of the cylinder head front end section with respect to the idler gear. The opening is closed with a cover which is disposed spaced from the idler gear installation bolt, so that no connection is made to the idler gear and the installation bolt therefor.

摘要： A cylinder head for an overhead camshaft engine comprises an end wall to which an idler is rotatably mounted, and two side walls which extend in generally parallel from the end wall. Upper and lower beams interconnect and extend between the two side walls. The side walls, and the upper and lower beams cooperate with each other to define a mounting site extending to surround a window opening. A cover is detachably mounted on the mounting site to conceal the window opening.

摘要： A camshaft driving arrangement for an internal combustion engine comprises a cylinder head formed with a cam chamber, and an idler chamber communicating with an oil pan and an end face of the cylinder head. The end face includes openings allowing communication between the cam chamber and the idler chamber. An idler shank is fixedly mounted on the cylinder head. An idler sprocket is rotatably supported on the idler shank, and includes a radial portion disposed adjacent the end face. The end face, the radial portion, and the idler shank cooperate with each other to define a passage allowing oil flowing out of the cam chamber via the openings to flow down toward the oil pan.

摘要： A camshaft driving arrangement for a DOHC engine comprises two pairs of cam sprockets, each pair being mounted to each of the camshafts at one end thereof, and two idler gears, each being rotatably mounted to one of the cylinder heads. A first camshaft driving chain drivingly interconnects one of the idler gears and the adjacent pair of the cam sprockets. On the other hand, a second camshaft driving chain drivingly interconnects the other of the idler gears and the other pair of the cam sprockets. The second camshaft driving chains have different running planes which are axially spaced along the axis of the crankshaft.

摘要： A structure of a cylinder assembly of an internal combustion engine has a coolant circulating system for cooling the cylinder assembly while the engine is driving. The cylinder assembly generally comprises a cylinder block formed therein a plurality of engine cylinder in line, and a cylinder head sealingly mounted on the cylinder block. The coolant circulating system comprises a coolant chamber formed within the cylinder block so that it surrounds substantial part of each engine cylinder, a return passage formed in the cylinder head. The coolant chamber communicates with the return passage through a plurality of vertical passages. Adjacent the top of the vertical passage, there is provided with a projecting portion inwardly projecting thereto. A sloped passage is formed within a partition disposed between each of adjacent engine cylinder. The upper end of the sloped passage is opened at the projecting portion at right angle to the planar surface of the projecting portion. By forming the projecting portion within the vertical passage and forming the sloped passage extending therefrom at right angle, it makes easy to form the sloped passage within the partition. Further, by forming the sloped passage as the manner mentioned above, the cylinder assembly is easily prevented from leakage of coolant and/or air/fuel mixture discharged to the engine cylinder.

摘要： An automobile is provided with an altitude compensated fuel feed means which comprises a fuel feed circuit with an air bleed orifice, an independent additional air supply passage leading to the fuel feed circuit, an air bleed control valve for opening the additional air supply passage, and a control unit with a manually operable part. The manually operable part is disposed in a passenger compartment. Operative interconnection between the control unit and the air bleed control valve is such that manually operating the manually operable part will cause the air bleed control valve to be opened to permit the entry of additional air into the fuel feed circuit, thereby making altitude compensation of the fuel feed means easy.

摘要： A manifold system for a multi-cylinder internal combustion engine. The manifold system includes intake and exhaust manifolds having a common wall forming the bottom of a heat riser. Within the exhaust manifold dual walled liner construction is installed to provide a reaction chamber jacketed by a fluid jacket in a manner that gas discharged from the reaction chamber is directed toward a heater wall disposed adjacent the common wall and then flows through the jacket chamber. The jacket chamber conveys the gas out of the exhaust manifold to an exhaust pipe.

摘要： An internal combustion engine has a main combustion chamber and an auxiliary combustion chamber which is connected to the main combustion chamber by way of a torch nozzle. A main carburetor communicates with the main combustion chamber to supply a large amount of lean combustible mixture, and an auxiliary carburetor communicates with the auxiliary combustion chamber to supply a small amount of rich combustible mixture. A rotary valve is disposed within the auxiliary carburetor downstream of its venturi section. The cross sectional area of an opening of the rotary valve is smaller than that of the venturi section.
