A tasty morsel for fans of technology: the five-valve cylinder head of the engine models with a working volume of 1.8 liters. With the help of a chain (1), the exhaust camshaft (4) with a toothed belt drive also drives the intake camshaft (2). The number "3" indicates the three cams of the intake valves of the cylinder. The number "5" shows both cams of the exhaust valves of the same cylinder.
Economy, sportiness, comfort – this is how one could characterise the various petrol engines in the A4: in first place would be the extremely economical 1.6-litre engine, then the golden mean – the 1.8-litre engine, accompanied by the sporty 1.8-litre Turbo, and then the emphatically comfortable six-cylinder engine.
