CT 152 Four-stroke petrol engine with variable compression for CT 159
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 engine used here is an air-cooled single-cylinder four-stroke petrol engine with external carburation. A modified cylinder head permits experiments with various combustion chamber inserts and compression ratios. To adjust the mixture composition, the carburettor was modified. CT 152 is fitted with a manual adjustment 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 as well as air 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.
