Abstract
Against a background of rising energy prices and tightening emissions legislation for stationary heat and power generation, gas engines are gaining in importance. Lean burn, spark-ignited (SI) gas engines are currently regarded as the state-of-the-art, however their maximum specific output is limited due to the spark plugs used in their ignition system. This limitation is obviated by the novel “Performance Gas Injection” (PGI) ignition system from MAN Diesel. With the new PGI process higher considerably mean effective pressures can be attained than with conventional SI gas engines.
