CT 152

- Engine for installation in the CT 159 test stand
- Part of the GUNT-FEMLine


Technical Description

In conjunction with the CT 159 test stand and the HM 365 load unit, the engine is highly suitable for investigation of different compression ratios, ignition timing adjustment and an adjustable jet nozzle.

The air-cooled single-cylinder four-stroke petrol engine is identical in design to the CT 150. A modified cylinder head permits additional experiments with various combustion chamber inserts. To adjust the mixture composition, the carburettor was modified. CT 152 is fitted with a special device to adjust the ignition timing - from advanced to retarded. 

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.
