New technology from Bosch reduces vehicle fuel consumption

0

A new technology from Bosch is said to reduce vehicle fuel consumption by 13%. It works by spraying a fine vapor of distilled water into the intake duct in the engine. The system is used in the new BMW M4 GTS.

An advanced combustion engine currently wastes around a fifth of its fuel, which is used to cool the engine before combustion. Cooling the engine reduces engine knocking, which delivers greater power. Bosch’s new technology replaces this with water; before the fuel ignites, a fine mist of water is injected into the intake duct. The water’s high heat of vaporization provides effective cooling, meaning that fuel is only used during the combustion process.
