  • Pressure wave supercharger with vibration damped rotor
    Patent number: 4646704
    Abstract: A pressure wave supercharger for internal combustion engines, particularly those in motor vehicles, has a rotor, driven in proportion to the engine speed, with a plurality of rotor cells oriented parallel to its axis of rotation. The cells are connected, at one end, in the exhaust gas flow between the exhaust manifold and the exhaust system and, at the other end, in the intake air stream between the air intake and the intake manifold. Placed on the rotor and concentric therewith is a rigid vibration damping ring, which is contacted by a support, firmly attached to the rotor, so as to create friction. The friction produced by sliding of the rigid ring on the support, acts to absorb a large part of the vibration energy of the rotor and thereby, correspondingly, to eliminate the production of annoying noise.

  • Engine cylinder intake port
    Patent number: 4606308
    Abstract: A cylinder intake port in an internal combustion engine which provides a combination of high swirl and flow efficiency. The port features roof ramps of differing angles leading on opposite sides of a valve axis into a swirl bowl with a shelf portion above the port throat. The flow path below the ramp of lower angle is generally tangent with the outer portion of the cylinder and yields a positive swirl component while the flow area on the opposite side of the valve stem remains relatively unrestricted.

  • Method and means for stimulating combustion especially of lean mixtures in internal combustion engines
    Patent number: 4556020
    Abstract: Method and means are disclosed for stimulating combustion especially of lean mixtures in internal combustion engines.
