200 injections in the blink of an eye.

The four-cylinder petrol engines in the BMW 116i, 118i and 120i.

On average, you blink about 10 times a minute. In this time, you miss 2,000 separate fuel injections supplying as little as 2 mg of fuel each time. This exceptional level of precision is made possible by the positioning of the piezo injectors which are located centrally between the valves. The engines in the BMW 116i, 118i and 120i with the Auto Start Stop function incorporate this cutting-edge technology allowing the car to operate in lean-burn mode for far longer and at far higher revs. This leads to improved efficiency, which in turn leads to better performance. Better performance from less fuel – what BMW EfficientDynamics is all about.
