In conjunction with the load unit, the test engine is a complete engine test stand. The connection to the brake is made via a rotationally elastic coupling with a jointed shaft. The engine is attached to the load unit by fasteners. The engine used here is a four-cylinder diesel engine. It has its own closed cooling water circuit. A solid welded frame on rollers, with a vibration-insulated base plate, carries the entire setup. Hazardous areas such as hot surfaces and rotating parts are covered with perforated plates.
Learning Objectives/Experiments:
