N2  - In this study, we explored the use of Multi-Wavelength Photoacoustic Spectroscopy (4?-PAS) in combination with a Scanning Mobility Particle Sizer (SMPS) to analyze diesel particulate matter (DPM). The goal was to provide a comprehensive, real-time analysis of diesel emissions across three engine modes using two different fuel types. Additionally, we investigated the thermal evolution of emissions at three different temperatures. The total number concentration (TNC) and total volume concentration (TVC) showed a retrograde tendency with increasing torque and RPM. The Optical Absorption Coefficient (OAC), measured using the 4?-PAS instrument, also decreased with rising torque and RPM. The qualitative analysis quantified using the Aerosol Ångström Exponent (AAE) showed a decline at higher engine RPM and torque, indicating an increase in the proportion of inorganic carbon in the emissions.
