  • Patent number: 10865706
    Abstract: A spherical linear two stroke engine (SLE) is shown and described. SLE is an opposed piston two stroke (OP2S), free piston engine with controlled power shaft. SLE is scalable, light in weight, small in packaging volume, has few parts and high power density. The SLE is also efficient, environmentally friendly and has many different applications.

  • Patent number: 8499729
    Abstract: An engine with an output shaft extending through the engine block and generally parallel to the piston, the engine includes a boost piston cylinder integral to the cylinder, and a boost piston for producing compressed air so as to supercharge the engine. The engine further includes an energy translation mechanism translating linear movement into rotary movement, an energy translation mechanism for reducing the side force that the piston exerts against the inner wall of the combustion chamber, an energy transforming member working in concert with an engine torque absorbing/motion control torque reaction device to eliminate the lemniscate motion from being translated to the piston and to absorb all engine torque to case ground through a rolling element bearing, and a port time control system having a shaft phaser to adjust the phase of the pistons or the position of the air control valve.

  • Patent number: 5070827
    Abstract: Low mass hydraulic and mechanical valve lifters are shown and described. The lifters are of oblong configuration for reduced mass, with straight or narrowed sides connecting longitudinally spaced ends having depending semi-cylindrical end walls that are received in similarly shaped end portions of lifter gallery openings to absorb all longitudinal and lateral side loads. The lifters are preferably made by investment casting of steel alloys. The investment casting permits the use of thin semi-cylindrical walls at each end of the valve lifters which also have internal reinforcing ribs extending on their undersides.
