Reciprocating engines consist of a piston reciprocating in a cylinder and connected to a crank shaft by a connecting rod. This cover includes a switch, which allows automatically stops the drive motor if the cover is opened. 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.
....A robust support pillar fixes to a suitable table or bench(not supplied) with a low natural frequency. The pillar holds a cantilever that holds a model four-cylinder engine.
A bench- mounting model four-cylinder engine that shows primary and secondary forces and moments in reciprocating masses and how to balance them. The model engine has a crankshaft, connecting rods, bushes , pistons and a cylinder block. A separate Control and Instrumentation Unit (included) controls a motor that turns the engine crankshaft. This product is an excellent follow-on from the Static and Dynamic Balancing equipment.
Experiments:
Primary and secondary forces and moments for different crank settings.
Comparing calculated forces and moments with actual results.
The effect of adding additional mass to one or more pistons for any chosen crank setting.
Primary and secondary forces and moments in popular engine configurations - one, two and four cylinder.
