Computer Controlled Balance of Reciprocating Masses Unit

Reciprocating engines consist of a piston reciprocating in a cylinder and connected to a crank shaft by a connecting rod. The Computer Controlled Balance of Reciprocating Masses Unit is mounted on an anodized aluminum structure with panels of painted steel. It includes rubber elements to have a vibration isolation and a transparent protective cover protects students from the moving crankshaft and allows the visibility of the practical exercises and elements of the unit. This cover includes a switch, which allows automatically stops the drive motor if the cover is opened.
