Using Precombustion Chambers to Ignite Lean Mixture

Features

Benefits

Highest energy ignition source
  • Provides the necessary energy to consistently ignite the lean mixtures required for low NOx emissions
  • Supports consistent firing via multiple simultaneous ignition sites along the torch path
  • Reduces main chamber ignition delay while promoting complete combustion
  • Supports combustion stability over engine’s entire operating range
Consistent ignition
  • Reduces misfire, detonation and cycle-to-cycle firing pressure variation
Enhanced performance at varying speeds and loads
  • Provides the ignition energy necessary to reduce NOx while keeping carbon monoxide (CO), non-methane hydrocarbons (NMHC) and fuel consumption at acceptable levels for best overall engine performance
Allows engines to meet or exceed today’s emission requirements
  • Adapts to changing needs when applied with other Dresser-Rand lean burn combustion system hardware upgrades
Proven OEM technology
  • Assures component compatibility for unmatched efficiency and reliability
