Exhaust Induction Device for the Improvement of Combustion Efficiency of Internal Combustion Engine : Carbon and Particulate Matter Footprint Reduction Analysis

Abstract

Objectives : The purpose of this study is to introduce an exhaust induction device (EID) for the improvement of combustion efficiency of internal combustion engines and to analyze fuel consumption savings with the installation of EID. To show the effectiveness of EID, The carbon footprint (CF) and particulate matter footprint (PMF) were calculated and compared before and after the EID installation and utilization.Methods : Firstly, the EIDs were installed in 39 Taxi vehicles that use LPG fuel. The monthly fuel consumption data were collected before installation and compared with three months after the EID installation. With the fuel consumption data, CF and PMF were calculated and compared.Results and Discussion : There were a few differences between EID installation Taxi vehicles. The results show that CF was 2.12E+00 kgCO<sub>2</sub> eqv., and PMF was 4.54E-03 kgPM2.5 eqv. per 1 km vehicle driving before EID installation. After EID installation, the three-month CF and PMF were reduced to 7%, 4%, and 8%, respectively. The CF and PMF result in each Taxi vehicle reduced from 1% to 27%. The overall results show that the EID installation can improve the combustion efficiency of internal combustion engines and reduce CF and PMF.Conclusion : The carbon and particulate matter footprint should be studied and reduced continuously in the transportation sector. In this study, a new EID for the improvement of the combustion efficiency of internal combustion engines was introduced. Also, CF and PMF were calculated using LPG fuel consumption before and after the EID installation. The results show that the EID installation can reduce fuel consumption, CF and PMF. The EID can significantly reduce fuel consumption, CF, and PMF in gasoline and diesel vehicles, fishing boats etc., producing more emissions. Further studies are needed considering drivers’ driving patterns, weather conditions, etc.
