Overview

Analysis demonstrates performance improvements with ethanol fumigation in CI engines, suggesting efficient and compliant retrofitting options.

Key Points

  • The project aims to analyze the effects of ethanol fumigation on combustion performance and emissions in CI engines.
  • Conducted a theoretical and data-driven analysis utilizing Kirloskar DA10 diesel engine.
  • Implemented low-level ethanol-air fumigation at varying energy substitution ratios (E2.5, E5, E10).
  • Assessed key performance metrics including brake thermal efficiency and emissions.
  • E5 fumigation showed the best performance with improved brake thermal efficiency.
  • CO emissions decreased by up to 30%, while smoke and particulate matter reduced by 30-40%.
  • Hydrocarbon emissions increased at part loads, but overall performance remained strong.
