Overview

Quantitative analysis shows enhanced IMEP and combustion efficiency in opposed piston engines, suggesting critical design choices for combustion systems.

Key Points

  • Controlling combustion chamber shape increases tumble flow and improves fuel utilization efficiency.
  • Optimized configurations led to a 9.72% improvement in indicated mean effective pressure (IMEP).
  • Combined tumble and swirl flows enhance spray dispersion, leading to more effective combustion.
  • Results indicate a significant increase in total heat release of 7.34% over baseline measurements.
