Investigating Real-world Emissions from Liquefied Petroleum Gas-fueled Vehicles: A Modeling Approach that Utilizes Portable Emissions Measurement Systems

The study presents an analysis of the emissions data from an LPG-fueled vehicle, focusing on key exhaust components. CO₂, THC, and NOx. Data were aggregated from road tests conducted using a Portable Emissions Measurement System (PEMS). Subsequently, the impact of various factors, including vehicle speed, engine load, and engine RPM, on the generated emissions was investigated.

In addition, the methodology for developing emission models, particularly for THC in LPG vehicles, is outlined. The results demonstrate the feasibility of creating reliable and robust emission models characterized by low mean squared error (MSE) and high R² values.

These findings contribute to a better understanding of the relationship between operational parameters and emissions, providing valuable information for emissions control strategies in vehicles powered by LPG. Research highlights the potential of data-driven approaches to improve environmental assessments and promote cleaner vehicle technologies.

The findings may prove useful in formulating emission reduction strategies and advancing technologies to reduce the environmental impact of LPG-powered vehicles.
