  • Patent number: 8464671
    Abstract: The horizontally opposed center fired engine improves on the traditional design of the horizontally opposed engines and center fired engines with a better engine geometry. The present invention utilizes four pairs of opposing pistons to compress a larger volume of air-fuel mixture within four different cylinders. The four different cylinders are radially positioned around a center axle in order to achieve a perfectly symmetric engine geometry. The center axle consists of two different shafts spinning in two different directions, which could drastically reduce engine vibrations in the present invention. Engine vibrations are caused by a change in engine speed and result in a loss of energy. Due to the design, the present invention will only experience energy loss in the form of entropy and friction. Thus, the present invention can convert a higher percentage of chemical energy into mechanical energy than any other internal combustion engine.

  • Publication number: 20110155083
    Abstract: A valve train for an internal combustion engine includes a camshaft, a valve-operating cam for operating an engine valve, and a link mechanism for swinging the valve-operating cam. The valve train also includes a holder member operable to turn around the camshaft, and a drive mechanism operable to turn the holder member for varying positions of the link mechanism. The drive mechanism includes a ball screw provided perpendicularly to the camshaft, a slider threadably engaged with the ball screw, an arm member swingably attached to the slider, and a connecting bolt having one end secured to an arm-connecting portion of the arm member, and the other end secured to the holder member. In such movable valve train for an internal combustion engine, the holder member and the drive mechanism are connected to each other with a small and lightweight configuration, requiring a minimal number of parts.

  • Patent number: 7966997
    Abstract: An oil return passage that is open at its upper end to a cam chamber and is open at its lower end to a crank chamber is formed to extend from a cylinder head to a cylinder block. A heat exchanger having a double-pipe structure is housed in the oil return passage. Lubricating oil fed from the cam chamber is passed through an oil-collection outer passage of the heat exchanger, and separated oil fed from a separator case of a PCV system is passed through an oil-collection inner passage of the heat exchanger, so that heat of the lubricating oil is imparted to the separated oil. Thus, water contained in the separated oil is evaporated, and the amount of water flowing into an oil pan can be reduced.

  • Patent number: 7918199
    Abstract: In a V-type engine, intake and exhaust rocker arms in each bank are arranged in a substantially inverted-V-shape in a plan view, so that side end portions of corresponding intake and exhaust push rods are positioned adjacent to each other. Slipper portions of first and second intake cam followers have end portions at one end along the axial direction of a camshaft protrude respectively in opposite directions to each other so that they face each other across an intake cam therebetween. Slipper portions of first and second exhaust cam followers have end portions at one end along the axial direction of the camshaft protrude respectively in opposite directions to each other so that they face each other across an exhaust cam therebetween. This reduces the distance between the push rods in each bank to provide a compact valve-operating device.

  • Publication number: 20110023800
    Abstract: A vee-engine has left and right cylinder banks have valve configurations that are mirror images of each other. The exhaust valves and associated exhaust ports are situated more toward the rear of the engine than the intake valves in any particular cylinder. With all the exhaust valves nearer the rear of the engine, the overall exhaust manifold runner length between the ports and the turbocharger is reduced relative to an engine with offset cylinder banks where exhaust valves in one bank are located nearer the front of the engine than exhaust valves of the other bank.

  • Publication number: 20110023818
    Abstract: An internal combustion engine includes a fuel system having a first fuel rail with an integrated diverter portion coupled to a high-pressure pump and separated from a common rail portion by a flow restriction device. The first fuel rail includes a pressure sensor coupled to the diverter portion at one end and a control valve coupled to the common rail portion at the other end of the same fuel rail. In V-engine embodiments, a second fuel rail communicates with the integrated diverter portion of the first fuel rail. In one embodiment, components including the first and second fuel rails, a pressure sensor, and a pressure or volume control valve are externally mounted outside the engine valve cover.

  • Patent number: 7878174
    Abstract: In a V-type multi-cylinder engine, a first fuel supply conduit is connected to fuel-injection valves in a first throttle body group corresponding to the first bank, and a second fuel supply conduit is connected to fuel injection valves in a second throttle body group corresponding to the second bank. A pair of first and second side plates connect adjacent ends of the first and second throttle body groups together. A distance between respective throttle bodies located in two ends of the first throttle body group is set shorter than a comparable distance between the throttle bodies located in two ends of the second throttle body group. A joint part for connectively receiving the fuel hose is provided at an end of the first fuel supply conduit in a way that the joint part is arranged between the two side plates.

    Abstract: A V-type internal combustion engine having a variable valve train for keeping the height of the internal combustion engine low. Disclosed is a V-type internal combustion engine with a variable valve train that uses an actuator to vary the phase/lift amount of camshafts. The actuator is mounted on head covers for each of a plurality of cylinder blocks arranged in a V-shape. The actuator is attached to a lateral surface positioned opposite the offset direction of the head covers. In an embodiment, the actuator is attached to a lateral surface of the head covers and positioned close to the inside of the V banks.
