Teilprojekt A4





As part of the subproject A4, a high-pressure pump for gasoline has been designed. The investigations performed within this project show that the use of advanced ceramics in gasoline-lubricated high-pressure pumps promises an approach of a reliable, low-wear, and low-friction realization of the high injection pressures needed for spray-guided gasoline direct injection engines.
