Balancing engine type VR-5
The article discusses balancing 4-stroke V-type and quasi V-type reciprocating engines, differing in vee-angles, angular offset of adjacent crankpins, and d?saxage. Formulae are given for calculation and analysis of forces of inertia induced by reciprocating and rotating masses, and moments of said forces in type VR-5 engines, as functions of vee-angle, crank radius/connecting rod length ratio, and cylinder axis relative d?saxage. A method is offered of balancing inertia forces from rotating and reciprocating masses as applied to VR-5 type engines.
