To meet the stringent downsizing demands faced by many vehicle manufactures, Bosch has developed an innovative water injection system for gasoline engines to improve fuel consumption and reduce emissions.

The system works by injecting a fine water mist into the intake manifold to cool things down so the engine is unable to overheat, providing increased torque even at high engine speeds.

Initially working with BMW, the system was tested in the BWM M4 GTS, but is now ready for other OEMs to adopt the technology. Bosch is targeting the technology at turbocharged engines with higher than 80kW/litre output. The technology will be used in three and four cylinder downsized engines, which will be suitable for many midsize passenger cars.
