The main advantages of using direct injection in an SI engine, such as lower fuel consumption and higher thermal efficiency, implicate a new problem concerning gasoline engines: the emission of particulate matter. The observed issue has been a significant direction of development of the contemporary DISI engine over the last decade. This paper contains an overview of the results of PN emission, which were obtained from experiments conducted at BOSMAL and from the literature. Current and future legal regulations regarding PN emissions were collated to the test results.
