Composition of Fuel System

Components in fuel system are designed to generate and distribute high pressure, and they are controlled electronically
by engine ECU. Accordingly, fuel system is completely different from injection pump type fuel supply system on the
conventional Diesel engine. The fuel injection system in common rail engine is composed of transfer pressure section
that transfers fuel in low pressure, high pressure section that transfers fuel in high pressure and ECU control section.
