  • Patent number: 9611820
    Abstract: The intake structure for an internal combustion engine includes: a collision surface configured to face an inlet of a carburetor; a deflecting surface configured to deflect a blowback flow, which is to diffuse after colliding against the collision surface, in one direction along the collision surface; a receiving surface configured to receive the blowback flow deflected by the deflecting surface; and a fuel-accumulating surface formed below the collision surface. A first clearance between an air-guiding direction distal end of the deflecting surface and the receiving surface is brought into communication to a downstream side of a filter of an air cleaner in a fresh-air intake direction so as to act as a main intake passage for fresh air.

  • Patent number: 9605630
    Abstract: An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, swirl consistency is improved between engine cylinders and between the left bank and the right bank, improving the consistency of power output and reducing emissions, particularly particulate emissions, also called smoke.

  • Publication number: 20150000625
    Abstract: A locking sealing arrangement for providing a fluid tight seal between a cap or a spigot and an adjacent structure is set forth. The locking sealing cap includes a peripheral sealing member such as an o-ring to form the fluid tight seal. The locking sealing cap engages the inner surface of the adjacent support structure by a cam-lock arrangement. A locking tab extends from the surface of the support structure. A tab-receiving slot is formed in the locking sealing cap. Once the locking tab is aligned in the tab-receiving slot, rotational movement of the locking sealing cap causes engagement of the locking sealing cap with the support structure. One embodiment of the locking sealing cap includes an internal torque feature for receiving a tool to allow engagement. In another embodiment of the locking sealing cap an external, multi-sided tool engagement surface is provided.

  • Patent number: 8887685
    Abstract: A method and apparatus for tuning an engine by a modified pod filter or velocity stack using a tunable pod air filter with base and cap members forming a housing that is joined together by a filter membrane to define a plenum or resonance chamber within the housing that contains only air drawn in through the filter. An aperture in the base member passes air to the inlet of an engine. A tuning sleeve is sealingly engaged within the aperture and extends into the plenum to control air flow out of the plenum and into the engine. The tuning sleeve is tubular with a pattern of vents through its surface to control flow rate. The vents may be drilled, punched or otherwise cut through the sleeve to control air flow. After being vented, the sleeve is reinserted into the filter housing and the filter is installed on the engine.

  • Patent number: 8863717
    Abstract: An intake device of an internal combustion engine has primary and secondary intake lines for aspirating primary and secondary combustion air, respectively. The primary intake line opens into a primary inlet chamber and the secondary intake line opens into a secondary inlet chamber of a filter housing. In comparison to the primary intake line, the secondary intake line has a configuration such that, in normal engine operation, a flow capacity of the secondary intake line, in comparison to a flow capacity of the primary intake line, is so minimal that secondary combustion air aspirated through the secondary intake line has a negligible effect on the performance of the internal combustion engine. When the primary intake line is closed, the flow capacity of the secondary intake line suffices to supply the internal combustion engine with a minimum combustion air mass flow required for operating the internal combustion engine.
