In conjunction with the CT 300 test stand, which includes a drive and brake unit, the four-stroke petrol engine CT 300.04 is highly suitable for use in teaching the fundamentals of engine functioning and measurement.
The engine used here is an air-cooled two-cylinder four-stroke petrol engine with external carburation. The engine is started, run in passive mode and slowed down by an electric motor mounted in the CT 300 unit. The brake unit is connected by way of a elastic claw coupling.
The engine is prepared for measurement of the cylinder pressure for indication, and additionally includes a sensor to measure the exhaust gas temperature. The sensor, ignition cut-off and fuel supply are connected to the CT 300 test stand.
The full load and partial load characteristic curves of the engine are plotted in experiments.
