Automotive Single Cylinder Petrol Engine with Variable Compression Ratio Model AM 133
The air-cooled single-cylinder four-stroke petrol engine is identical in design to the four cylinder engine. A modified cylinder head permits additional experiments with various combustion chamber inserts. To adjust the mixture composition, the carburetor was modified. Sci-tech AM 133 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 AM501 test stand.
