The general layout design of the CM6T28F series CAMC natural gas - powered generator is a design scheme determined by fully considering the characteristics of natural gas combustion. Main structural features: Adopt advanced design structures such as single overhead camshaft, integral four - valve cylinder head, in - line six cylinders, water - cooled wet cylinder liner, four - stroke, rear gear chamber, etc.; Water - cooled turbocharger, special piston for shallow - basin type gas engine, high temperature and wear - resistant valve seat ring, special piston ring for gas engine to prevent oil burning. Control system: Woodward PG + low - pressure gas injection system, and matching intelligent high - energy ignition system.
