MULTICYLINDER BOXER CRANKSHAFT ASSEMBLY

摘要

In typical internal combustion engines and compressors, etc., it is known to have a piston, moving in a cylinder, connecting rod and a crankshaft, as a crankshaft system. The gas and inertia forces press the piston against the cylinder side wall and produce bending stresses in the connecting rod. With increased speed the effect of inertia forces may exceed this of gas forces. The second harmonic inertia force may cause bigger stresses than its first harmonic. This puts heavy demand on all components, posing limitations to speed and power. Balancing is also difficult.
