Improved methods of injecting petrol into the intake port represent more or less the limit of what can be done to optimise economy with conventional techniques. The direct injection principle opens up new possible ways of creating more economical and  environmentally sound petrol engines.

Thrifty diesel engines employ direct injection, in other words, the amount of fuel supplied
corresponds exactly to the requirements at any given time.

The logical next step – at least in theory – would therefore be to apply the principle of direct
injection to petrol engines as well. FSI technology from Audi opens up a whole new dimension for the petrol engine.
