  • Patent number: 10858989
    Abstract: An exhaust manifold for an internal combustion piston engine with a row of at least two cylinders inclined from the vertical. The exhaust manifold has plural exhaust stack assemblies and a manifold plenum with an outlet. Each of the plural exhaust stack assemblies comprises a leader pipe and an exhaust connector, with a first end of each leader pipe being joined to a first end of the exhaust connector of the exhaust stack assembly, and a second end of each exhaust connector being joined to the manifold plenum. Each leader pipe is joined to a manifold flange that is adapted for joining to the internal combustion engine to receive exhaust gases from the cylinders of the engine. Each leader pipe is joined in a vertical plane to the manifold flange at a first angle so that the plural exhaust stack assemblies are approximately horizontally oriented when joined to the internal combustion engine, and each leader pipe is joined in a horizontal plane to the manifold flange at a second angle inclined toward the outlet.

  • Patent number: 8647087
    Abstract: A hydraulic motor having a cooling system includes a stator, a rotor that rotates and orbits in the stator, a drive link connected to the rotor, and a housing connected with the stator. The housing includes a working fluid inlet port, a working fluid outlet port, a cooling fluid inlet port, and a cooling fluid outlet port. Each port extends through the housing and is configured to connect with a different associated external fluid line. Pressurized fluid enters the working fluid inlet port to rotate and orbit the rotor en route to the working fluid outlet port. The cooling fluid ports are isolated from the working fluid inlet port and the working fluid outlet port within the housing.

  • Patent number: 8596050
    Abstract: A sound attenuating heat exchanger for an internal combustion engine includes a housing, a barrier wall and a fin. The housing includes an exhaust inlet, an exhaust outlet, a coolant inlet and a coolant outlet. The exhaust inlet is connected to the exhaust outlet by an exhaust flow passage. The coolant inlet is connected to the coolant outlet by a coolant flow passage. The barrier wall fluidly separates the exhaust flow passage from the coolant flow passage. The fin extends from the barrier wall into the exhaust flow passage, and includes a resonator adapted to attenuate sound waves traveling through exhaust gas within the exhaust flow passage. The barrier wall and the fins are adapted to exchange heat energy between the exhaust gas flowing through the exhaust flow passage and coolant flowing through the coolant flow passage.

  • Patent number: 8584448
    Abstract: A motorcycle includes an engine configured to expel an exhaust from combustion chambers of cylinders in a cylinder head through exhaust ports. Each of the cylinders is provided with a recessed portion provided in an exhaust passage wall surface in a central portion of an exhaust passage of a corresponding exhaust port. This makes it possible to maintain flow rate and flow velocity of the exhaust gas, and to decrease exhaust loss. As a result, it is possible to increase engine torque by use of a simple structure. In addition, no restriction is imposed on the layout of parts around the engine, because the recessed portions are provided in the exhaust ports.

    Abstract: An exhaust device (2) for an internal combustion engine (3) has an exhaust line (5) with a rear section X with two exhaust pipes (11) connected to an acoustic actuator (12) in a sound-transmitting manner. Better acoustic characteristics and increased number of noises audible from the outside is guaranteed by the exhaust pipes (11) being of different designs and/or by the actuators (12) being able to be actuated individually. A process for controlling the actuators (12) uses a control device (25) that actuates the actuators (12) individually to generate different acoustic signals (23) of the respective actuators (12). A motor vehicle (1) is provided with such an exhaust device (2) with acoustic actuators (12) controlled by such a process. The motor vehicle (1) has additional actuators (29, 31), which are especially associated with an intake line (30) and are arranged in the interior of motor vehicle (1).
