In conjunction with the CT 400 load unit, the CT 400.01 engine is a complete engine test stand. The engine used here is a four-cylinder petrol engine with a controlled catalytic converter. 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. 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 is fitted with sensors that measure the temperatures and the cooling water flow rate. The switch cabinet contains all of the electronic equipment for managing the engine (factory set). On the switch cabinet are an ignition key, an operating time counter and warning lamps. Data is transferred between the CT 400 load unit and the engine via a data cable connecting the switch cabinets for the two units. A starter battery is also housed in the frame.
For safety reasons, the engine has been modified in a way that it only starts when it is connected to the load unit both mechanically and electrically.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
