CT 100.21 Two-stroke petrol engine for CT 110
In conjunction with the CT 110 test stand, which includes a drive and brake unit, the two-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 two-stroke petrol engine with reverse scavenging. The engine is started and slowed down by an electric motor mounted in the CT 110 unit. The air cooling is effected by a flywheel fan. The brake unit is connected by way of a elastic claw coupling.
The engine is prepared for measurement of the cylinder pressure for indication. It includes a sensor to measure the exhaust gas temperature and a connection to measure the intake pressure. Both sensors, 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.
