High Density Gas Engine With Micro Pilot Compression Ignition Method

Niigata Power Systems Co. has launched the strategic sales activity of the newly developed gas engine with high BMEP of 2.0MPa, high electric thermal efficiency of 40% or more. The 22AG engine, which denotes “Advanced Gas,” produced 30% higher power than a conventional spark ignition gas engine. The first three units of 8L22AG corresponding to 3780 kW / 900min−1 have been put into service operation since July of 2002 as the key-hardware in co-generation system of the chemical plant in Japan. The second delivered 6L22AG is operated using pyrolysis gas produced in the waste treatment process from December of 2002.Copyright © 2003 by ASME
