Delphi develops new high-pressure common rail systems for heavy-duty and light-duty engines; Euro VI and beyond

Green Car Congress

At the same event, Delphi also revealed a new common rail system for small, one- to four-cylinder diesel engines, including non-automotive applications. This concept system is expected to be ideal for heavily downsized applications and developing markets. New high pressure heavy duty common rail systems. Resources. Crossley, D.
