Motor

All 2CV and derivatives have an air-cooled twin-cylinder boxer engine with central camshaft and 2 valves per cylinder. All engines can run smoothly on unleaded fuel. Any lead additives are not required. The preparation of the mixture is always done with a carburetor. Injection or catalysts never came out of the factory.

On the nameplate attached to the top of the engine, you can easily see which engine it is.
