Abstract:
This invention provides output gain by rotating a solid wheel from the center of mass as an input and connecting a lever to the edge of the same wheel at 180 degrees apart to each other. Each lever is connected at 180 degrees apart at the input rotating wheel with a common fulcrum located near the output side. This lever, acting as a mechanical lifting device, drives one side of output gain driven by the ratio of the length of lever to and from fulcrum between input and output while the other side is provided by another lever at 180 degrees apart. A unidirectional rotor converts the lever motion of up and down to a rotational motion. Weight of materials in a system is recycled back as an input to a hydraulic lever that generates hydraulic pressure driven by the movement of the system weight as it bounces off the surface.

Abstract:
[PROBLEMS] To enhance freedom in designing an engine, improve acceleration feeling, provide extremely excellent driving feeling, and enable an engine to be more compact. [MEANS FOR SOLVING PROBLEMS] An in-line four-cylinder engine for a vehicle has a two-plane 90° crankshaft (3). The weight of a crank web for each cylinder is distributed to left and right web half bodies (21a,b-24a,b) to satisfy the expression of (KL - 0.25)(0.25 - KR) ≈ DR/DL, where KL and KR are balance ratios of web half bodies of each cylinder (where KL <> 0.25, KR <> 0.25), and DL and DR are the distances from the center in the longitudinal direction of the crankshaft to each crank web half body. This causes the vector locus of first moment of inertia to be substantially a circle to cancel the first moment of inertia by a primary balancer (6).
Abstract:
A V-type internal combustion engine, having (2n+1) (n; natural number) cylinders, is provided with a crank shaft having n common crank pins Kc to which a pair of pistons in two banks are both connected and one stand-alone crank pin to which the remaining one piston only is connected. The common crank pins Kc are arranged at an equal phase, with a bank angle THETA set to satisfy the expression THETA = cos (1/(2n)). The stand-alone crank pin is disposed, when the remaining piston belongs to a bank on an advance side in a crank shaft rotation direction, on a lag side in a crank shaft rotation direction with an angle of (180- THETA ) degrees away from a common crank pin Kc, the masses M of reciprocating-motion portions such as pistons in all cylinders are set equal, and the crank shaft is provided with a balance weight WB that generates a balancing force having a magnitude of kMr omega in a ( alpha +180)-degree direction, when k = 2ROOT {[1/2 2ROOT (1-1/4n )] + (n-1/4n) } alpha =sin [1/2 2ROOT (1-1/4n )/k], where alpha : rotation-direction angle from common crank pin Kc M: mass of each reciprocating-motion portion r: crank radius omega : angular speed of crank shaft. Accordingly, an odd-cylinder V-type internal combustion engine is provided that prevents a primary vibration generation to be caused by a primary inertia force without increases in weight and size of the internal combustion engine.
