The study assessed the ability of a novel particle sensor to provide adequate evaluation of real-time emissions from modem diesel engines and estimate the effectiveness of emission control devices. Emission data were obtained from vehicles in real-world field conditions under various test cycles. The datasets were used to determine whether there is an association between particulate matter (PM) measurements produced by particle sensor and the PM measurements from reference instrument. Exploratory analysis was combined with statistical techniques to investigate suitability of particle sensor to adequately measure PM mass concentrations in exhaust gases of modem diesel vehicles. Results of the study identified strong positive association between measurements from particle sensor and reference instrument. Study confirmed the suitability of the sensor in the field to measure PM emissions of diesel vehicles. These findings are useful to researchers and governmental agencies involved in regulation, control, and monitoring of diesel engine emissions.
