Balance Of Reciprocating Masses

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.
