Did you know that gasoline engines waste about a fifth of their fuel on cooling parts of the engine block? With its new water injection, Bosch not only reduces this fuel consumption by up to 13%, but also increases the power of gasoline engines. This innovative engine technology bases on the simple fact that an engine mustn’t overheat. Instead of using evaporating fuel for cooling, a fine mist of water is injected into the intake duct – before fuel ignites. It’s an effective way of cooling, especially applicable to three- and four-cylinder downsized engines
