GASOLINE DIRECT INJECTION (GDI) SUPPLY PUMPS

Stanadyne has developed high-pressure gasoline supply pumps for homogeneous and stratified direct injection engines. These 200-bar capable demand control pumps are available in one and three piston configurations, with delivery capacities up to 1,400mm³ per pump revolution. They are suitable for use in gasoline/alcohol blend fuels such as E10, E22 and E85. The three-piston pump is currently supplied to Mercedes Benz for the M272 direct injection V6 engine. The single-piston pump is in development for applications in Europe, Asia, and North America.
