Laser Ignition for Lean-Burn Engines
|
 Researchers
at the National Energy
Technology Laboratory have successfully operated a
laser-spark lean-burn natural gas reciprocating engine. Development of
lean-burn engines is driven by demand for higher efficiencies and lower
emissions, but delivering the high energy required to ignite an ultra-lean
mixture destroys even the hardiest spark plugs. Plug durability is rapidly
becoming a barrier issue. According to team leader Mike McMillian,
laser-spark ignition solves heat loss problems and provides focused energy
capable of ignition even under ultra-lean conditions unignitable with
conventional systems. |
