Reduction in PM 99.81%
Emissions Standards for MRMM Graph

M&H Stage V engines demonstrate exceptionally low DEF consumption

  • EGR decrease Nox emissions out of the engine
  • Ultra-Low DEF consumption (1-3%) compared to no-EGR engines.
  • Requires lower dosing rates of DEF, which means:
  • Smaller DEF tanks
    • Easier integration for OEMs
    • Lower operating costs
    • Fewer fill-ups for operators
