CT 150 is part of a series of units enabling experiments to be performed on engines and machines. In conjunction with the CT 159 test stand and the HM 365 load unit, the simple 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 HM 365 unit. The air cooling is effected by blades attached to the flywheel. The HM 365 load unit is coupled by way of a pulley on the drive shaft. The engine includes a sensor to measure the exhaust gas temperature. The sensor, ignition cut-off and fuel supply are connected to the CT 159 test stand.

  The full load and partial load characteristic curves of the engine are plotted in experiments.

In conjunction with CT 159 test stand + HM 365 load unit
- Familiarisation with a four-stroke petrol engine
- Plotting of torque and power curves
- Determination of specific fuel consumption
- Determination of volumetric efficiency and lambda (fuel-air ratio)

- Determination of the frictional power of the engine
