CT 100.20 is part of a series of devices enabling experiments to be performed on engines and machines. In conjunction with the CT 110 test stand, which includes a drive and brake unit, the four-stroke petrol engine is highly suitable for use in teaching the fundamentals of engine functioning and measurement. The engine used here is an air-cooled single-cylinder four-stroke petrol engine with external carburation. The engine is started by an electric motor mounted in the CT 110 unit. The air cooling is effected by blades attached to the flywheel. The brake unit is connected by way of a elastic claw coupling. The engine is prepared for measurement of the intake pressure, and additional includes a sensor to measure the exhaust gas temperature. The sensor, ignition cut-off and fuel supply are connected to the CT 110 test stand. The full load and partial load characteristic curves of the engine are plotted in experiments.
