摘要： A Circle-Ellipse Engine comprises a stationary circular outer Housing having a fixed elliptical inner cam surface, and a separate internal round Rotor partitioned into equal segments that are populated by identical movable radial Vanes. During rotation, the end of the Vanes are positioned a constant distance from the elliptical inner cam surface of the Housing. The internal round Rotor has the same radius as the minor axis of the elliptical inner cam surface. During rotation, a variable height cavity is created representing the difference between the major and minor axes of the elliptical inner cam surface and the Rotor face.The position of the radial Vanes is guided by the slots in the symmetrical Rotor, extending to the elliptical inner cam surface of the Housing. The precise extension is governed by a pin track machined into the dual End Plates.There are no pistons, camshaft, timing chains, valves, valve lifters, rocker arms, connecting rods, or wrist pins. As a benefit, size and weight are significantly reduced when compared to a reciprocating engine of similar horsepower. Normal aspirated air is continuously drawn into the engine when an adjacent pair of radial Vanes passes the air inlet port. Similarly, exhaust products are expelled after a combustion event when the pair of adjacent Vanes passes over the exhaust port.The resultant geometer results in a continuous implementation of the Otto Cycle; namely intake, compression, expansion or power stroke, and exhaust during a single rotation of the internal round Rotor.Because the Otto Cycle is executed each revolution of the Rotor, the Circle-Ellipse Engine achieves the same power as a conventional reciprocating engine of the same displacement and compression ratio, at half the RPM. This implementation greatly reduces component ware and extends the life and maintenance cycle by a factor of four. As a side benefit, the power losses and vibration common to all reciprocating engines are eliminated.

摘要： A crankshaft lubricating oil passage structure of a V-shaped engine includes a main oil passage and a sub oil passage. The V-shaped engine includes a pair of banks. The pair of banks includes cylinders and is disposed in a V shape with respect to the crankshaft. The V bank angle as an included angle of the cylinders of the respective banks is set at a narrow angle. The main oil passage is provided between the pair of banks in the cylinder block or the crankcase. The sub oil passage extends from the main oil passage to the bearing portion of the crankshaft and guides lubricating oil to the bearing portion. The main oil passage is formed by connecting divided passage portions that are divided partway in an axial direction by an oil passage connection member that is a separate member from the cylinder block or the crankcase.

摘要： An internal combustion engine is provided with one or more oil drain-back passages. The oil drain-back passage include an entrance into a crankcase via a crankcase breathing window, the crankcase breathing window disposed within and through a bulkhead wall of the crankcase. Thus, each oil drain-back passage may be routed from a cylinder head of the engine to a crankcase breathing window where oil may then enter the crankcase and flow downward into an oil pan coupled to the crankcase.
