  • The formation and the oxidation of the particulate matter (PM) in a direct injection (DI) Common Rail (CR) optical diesel engine were analysed by means of spectroscopic and conventional methods, respectively. In particular, the broadband ultraviolet - visible scattering and extinction measurements allowed following the process of the PM formation and the oxidation as well as the chemical nature and sizing of the particles in the cylinder. Moreover, conventional instruments such as an electrical low pressure impactor (ELPI) and gaseous analysers allowed evaluating the particles size and the chemical nature at the exhaust. Several engine operating conditions were investigated by means of the flexible electronic control unit capable of operating up to five injections per cycle with different start of injection and dwell time. The diesel conventional and advanced strategies were analyzed such as the homogeneous charge compression ignition (HCCI) and the low temperature combustion (LTC). The PM produced and emitted by conventional diesel process is principally due to the soot particles ranged from 3-100 nm; on the other side, HCCI and LTC showed the mixture of particles made by soot plus hydrocarbons with size larger than conventional diesel process.
