    摘要： The disclosure relates to reciprocating piston engines having four cylinders with a circular cross section, cylinder axes which are parallel to one another, and an output shaft. The cylinder axes, as viewed in axial section, lie at the corner points of a rectangle that is a square, with the output shaft, which extends parallel to the cylinder axes, in the center of the square. Each pair of cylinders which lie diagonally opposite one another are arranged in the same direction, as viewed axially, and in opposite directions, as viewed axially, with respect to the other pair of cylinders. The force or moment from each cylinder is transmitted to the output shaft via a dedicated rotating crank and a toothing system.

    摘要： A multi-link engine is provided with an upper link, a lower link and a control link. The upper link is pivotally connected to a piston by a piston pin. The lower link is rotatably mounted on a crankpin of a crankshaft and connected to the upper link by an upper pin. The control link is rotatably connected to the lower link by a control pin and pivotally mounted on a pivot portion of a control shaft. The links are configured and arranged with respect to each other such that inertia forces of a prescribed second or higher order in terms of an engine rotational speed act on at least the upper link and the control link in a transverse direction of the engine with a sum of leftward and rightward inertia forces of the prescribed second or higher order being substantially zero.

    摘要： [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).

    摘要： An odd-cylinder V-type internal combustion engine including 2nnull1 cylinders (n is a natural number) arranged in two banks and pistons fitted in the cylinders has a crankshaft provided with n common crankpins (KC) each connected to the two paired pistons respectively belonging to the two banks, and one odd crankpin (KS) connected to the one unpaired piston. The common crankpins (KC) are disposed at the same phase. Bank angle null between the two banks meets nullnullcosnull1(1/2n). The odd crankpin (KS) is disposed (180nullnull)null behind the common crank pins (KC) with respect to the rotating direction of the crankshaft when the unpaired piston belongs to the front bank with respect to the rotating direction of the crankshaft. Reciprocating parts including all the pistons fitted in the cylinders have the same mass (M), and the crankshaft is provided with balance weight means capable of generating a balancing force of kMrnull2 acting in a sense of (nullnull180)null, where: 1 k = ( 1 2 null 1 - 1 4 null n 2 ) 2 + ( n - 1 4 null n ) 2 null = sin - 1 ( 1 2 null 1 - 1 4 null n 2 k ) null: Angle from the common crankpins in the rotating direction M: Mass of each reciprocating part r: Crank throw null: Angular velocity of the crankshaft The odd-cylinder V-type internal combustion engine prevents generation of a primary vibration caused by a primary inertial force without entailing increase in weight and size.

    摘要： A scroll saw is disclosed having a yoke with upper and lower reciprocable arms terminating in upper and lower ends having a saw blade connected therebetween. A motor, with a horizontally extending drive shaft, is mounted on the base for the saw. A connecting rod is coupled eccentrically at one end to the drive shaft and at the other end to the lower arm of the yoke. A second shaft is rotatably mounted on the base parallel to the drive shaft and is driven by intermeshing gears on the shafts. First and second counterbalances are mounted on the shafts which rotate with the shafts in opposite directions. The counterbalances, each having a center of mass offset radially from an axis of the shaft, are positioned on the shafts so as to enhance or compound the inertial effects of the counterbalances in a vertical direction to cancel out the inertial effects of the reciprocating yoke, and so as to cancel the inertial effects of each other in a horizontal direction.
