    Abstract: A constitution of protecting a fuel delivery tube of an engine, includes: 1) an engine body including: a) a cylinder head, and b) a ladder cam bracket defining an outer wall on a side section thereof, including: i) an outer frame, ii) an intake cam bracket, and iii) an exhaust cam bracket integrated with the outer frame and holding an exhaust cam shaft; 2) the fuel delivery tube disposed beside the engine body and extending in a direction substantially along a row of a cylinder; and 3) an intake manifold made of a material free from a metal. The outer wall of the ladder cam bracket is formed with a protrusion which protrudes toward a branch section of the intake manifold in such a manner as to prevent the branch section of the intake manifold from causing an interference with the fuel delivery tube.

    Abstract: A valve-operating device for an engine includes a camshaft which is disposed on one side of a plane including axes of an exhaust valve and an intake valve and which has an axis substantially perpendicular to the plane. The camshaft and the exhaust and intake valves are connected to each other through a first rocker arm and a second rocker arm which are swingably carried on a rocker shaft disposed substantially perpendicular to the plane. The camshaft is formed with a large-diameter exhaust cam and a small-diameter intake cam adjoining a portion of the exhaust cam on the side of the plane. The exhaust and intake rocker arms are provided with arm portions extending in an axial direction of the camshaft to come into sliding contact with outer peripheral surfaces of the exhaust and intake cams, respectively. Thus, it is possible to open and close the exhaust and intake valves with inherent opening and closing timings, while easily avoiding interferences among components.

    Abstract: An accessory drive for an overhead cam internal combustion engine wherein the accessory may comprise a high pressure positive pump for a fuel injection system. The engine includes at least one camshaft that is rotatably journaled within a cam chamber formed by a main cylinder head member and a cam cover that is affixed to it. One end of this camshaft is journaled by a bearing cap that has a portion which extends forwardly beyond the cam chamber and which cooperates with the main cylinder head member to define a recess in which a portion of the housing of the accessory is contained and affixed. An accessory drive shaft extends through this mounting portion and is drivingly coupled to the camshaft end. If desired, this front bearing cap may also mount a timing sensor that will project through the cam cover.

    Abstract: A variable valve timing mechanism for an internal combustion engine wherein the camshaft is supported at one end by a combined bearing and valve body member that is detachably connected to the supporting engine body. The connection is such that fluid from the engine lubricating system can be delivered to this body and distributed by a control valve mounted in it. This simplifies machining of the engine body and permits a more compact, lower cost construction without sacrificing any function. The control valve is mounted in a bore that is accessible through the side of the cylinder head and is actuated by a servo motor mounted on the exterior of the cylinder head to provide a compact, rigid and easily serviced assembly.

    Abstract: A first thrust limiting member and a second thrust limiting member are provided on a cam shaft rotatably carried between a lower cam shaft holder and an upper cam shaft holder which are fixed to an upper surface of a cylinder head 1, so that the first and second thrust limiting members and abut against the cam shaft holders 9.sub.5 and 10.sub.5. The second thrust limiting member has a plurality of detected projections provided around of an outer periphery thereof, so that the detected projections are detected by a TDC sensor 37 mounted to a head cover of the engine. Thus, the rotated position (phase), the angle of rotation and the number of rotations of an rotary shaft of an engine such as a cam shaft 6e and a crankshaft can be detected with good accuracy in a structure including a decreased number of parts, and the axial dimension of the rotary shaft of the engine can be reduced.

    Abstract: The present invention provides a direct injection type multicylinder engine capable of reducing the dimensions and number of parts thereof by forming so as to be used in common the cam brackets for retaining cam shafts, clamp members for fixing adjacent injectors, and fixing stud bolts. The cam brackets comprise singly formed parts, and retain the cam shafts rotatably on a cylinder head. The clamp members are adapted to fix adjacent injectors to the cylinder head at once. The cam brackets and clamp members are fixed to the cylinder head by inserting first common stud bolts through the central portions of the cam brackets and those of the cam brackets. The engine can be miniaturized by reducing the distance between the cam shafts, and the number of the parts required to retain the injectors and cam shafts is reduced.

    Abstract: An engine includes a crankshaft, a camshaft being driven by the crankshaft for opening and closing intake valves, a variable valve timing mechanism (VVT) attached to one end of the camshaft, which applies torque to the camshaft so as to change the valve timing. The camshaft has an increased outside diameter at a portion adjacent to the VVT as compared to other portions that are more distant from the VVT.
