New Methodology for Early Injector Qualification in Real Engine

Abstract

Despite the main stream powertrain technologies such as electrification, sophisticated exhaust after treatment systems and modern transmission concepts, the high pressure fuel injection will be an important component also in the future. The main reason for this circumstance is that while the powertrain technologies have become substantially more powerful, also the legal requirements have become significantly more challenging and so low engine out emissions remain to be also a major development target in the future. This is in line with publications from Daimler and BMW who declare that beside sophisticated after treatment systems and powertrain electrification very good engine raw emissions will be inevitable.
