| PROJECT AIM: Premixed charge compression ignition (PCCI) is one of the most promising combustion strategies for internal combustion engines, since PCCI combustion is able to realize very low soot and nitric oxide emissions while maintaining high fuel efficiency. To achieve PCCI combustion with limited heat release rates, the influence of charge stratification on combustion will be investigated. In this project methods are investigated to achieve and measure charge stratification. As a first attempt to investigate the mixing process we measure in-cylinder velocities using time resolved particle image velocimetry (TR-PIV). |
