Propane / HCCI

• Propane, n-pentane, hydrogen High Octane
  Gaseous Fuel
• N-heptane, n-hexane Low octane fuel
• Premixed compression ignition is an only to
  overcome the lean flammability limit of premixed
  spark ignition engines.
• NOx is function of the amount of mass that
  reaches these high temperature.
• At lower values of the equivalence ratio, the
  flame speed is further reduced and combustion
  takes even longer to complete.
