Dual-Fuel Methanol and Pilot Diesel

Pilot diesel atomizes and is evenly distributed in combustion chamber thus creating multiple ignition spots

  • For cylinder diameter exceeding 100 mm, detonation tendency of spark plug increases
  • Faster combustion progress given multiple-points ignition vs ONE point ignition (spark plug)
  • More effective “knock control“ as multiple-points ignition means faster combustion and less residual fuel mixture detonating
  • Refer to Nozzle Spray/Spark Ignition pattern diagrams below
