At the Chair of Internal Combustion Engines at the Technical University of Munich in collaboration with Hitachi Europe, the influence of extreme injection pressures on the engine and emission performance was investigated for different combustion modes. A conventional diesel injector was equipped with an optimized nozzle, which promises an improved mixture formation for both homogenous and stratified operation.

Initial Situation

In the past years, many studies have investigated the formation of Particle Number (PN) emissions in Direct Injection Spark Ignition (DISI) engines for both homogenous and stratified combustion [1-10]. With the introduction of new testing procedures and more stringent emission regulations, the need to reduce PN emissions is even more prominent. One key technology for reducing PN emissions in those engines is to improve the mixture formation by elevating the injection pressure. Although a lot of research has been done regarding the influence of increasing the...
