Key Points

  • This research aims to determine how the addition of ethylene glycol affects the emission characteristics of diesel engines.
  • Blended diesel with ethylene glycol at concentrations of 5 vol.%, 10 vol.%, and 15 vol.%
  • Measured exhaust emissions of hydrocarbons, carbon monoxide, nitrogen oxides, and particulate matter
  • Conducted tests under various engine loads
  • Adding 5 vol.% EG reduced HC emissions significantly compared to regular diesel fuel.
  • At 15 vol.% EG, CO emissions decreased by 20% under high engine load.
  • NOx emissions showed a modest reduction at all EG concentrations, indicating improved emission control.

Abstract

This study investigates the effect of Ethylene Glycol (EG) addition on the emission characteristics of a single-cylinder diesel engine. Light oil was blended with EG at concentrations of 5 vol.%, 10 vol.%, and 15 vol.%, respectively. The exhaust emissions of HC, CO, NOx, and PM were measured under different engine loads. The objective of this study is to clarify how the addition of EG influences the emission behavior of diesel engines.
