Piston secondary movement
Among other things, the lateral movement of the piston in the cylinder is crucial for the service life of engines. Miniature eddy current sensors for this are integrated in the piston which measure onto the cylinder wall. If the distance is too large or too small, the piston has too much play or continuous lubrication cannot be ensured. The sensor cables are routed out of the engine along the connecting rod over a rocker in the gearbox.
