The Engine


For the Opel Ascona A two kinds of 4-cylinder engines were used: On the one hand the CIH-engines (Camshaft In Head) with a displacement between 1600 cc and 1900 cc, who were already used in the Opel Rekord C. On the other hand the OHV-engine (Overhead Valves) with a displacement of 1200 cc, who was already used in the Opel Kadett B. Below who can see fundamental technical data about these engines. The selection left shows the specific data of the respective engine types.
