Test bench, especially for piston connecting rod bearings, has a powered crankshaft for the piston in a cylinder with a gas zone

摘要

The test bench (1), for motor components, has a crankcase (2) to take a free-rotating crankshaft (3) with at least one eccentric journal (4) and a crankshaft drive motor (6). A cylinder (9) holds a piston (8) forming a gas zone (11). The piston is linked to the crankshaft by a connecting rod (7) at the eccentric journal. A controlled gas feed line (13) is at the gas zone through an exchangeable cylinder head (10) or the cylinder wall.
