IN-LINE INTERNAL COMBUSTION ENGINE HAVING A MULTI-JOINT CRANK DRIVE AND A SINGLE BALANCE SHAFT FOR DAMPING SECOND-ORDER INERTIA FORCES

摘要

An internal combustion engine has a multi-joint crank drive wherein the multi-joint crank driver includes a plurality of coupling members which are rotatably supported on crank pins of a crank shaft and a plurality of hinged connecting rods which are rotatably supported on crank pins of an eccentric shaft wherein each of the coupling members is pivotally connected to a piston connecting rod of a piston of the internal combustion engine and one of the articulation connecting rods. In order to enable to largely or completely compensate inertia forces, it is proposed according to the invention to equip the internal combustion engine with a single balance which serves for neutralizing second order inertia forces.
