Delphi Diesel Systems has developed a range of Ultra High Pressure Common Rail fuel systems, with up to 3000 bar capability to enable Heavy Duty Vehicles to meet the requirements of Euro VI and future emissions legislation. The new technology range builds on the performance of the 2500 bar Advanced Fuel Systems E3 (EUI) and E3P (EUP + SMART Injector), with the addition of full common rail flexibility, improved controllability and injection pressures in excess of any of today's existing benchmarks. Delphi's Distributed Pump Common Rail System (DPCRS) provides common rail functionality for camshaft driven FIE engines with minimum modification, whilst the Remote Pump Common Rail System (RPCRS) provides equally advanced performance but with an external flange mounted pump. Both systems deliver precise and accurate control of multiple injections at maximum rail pressure across all engine operating conditions, thus minimising the demands on exhaust after treatment systems. They are designed for maximum flexibility of application, where the pumping capacity of the system can be adjusted for a wide range of engine applications, enabling the efficiency of the FIE system to be maximised whilst maintaining engine platform commonality. Additionally DPCRS also employs a unique method of pump fuel metering and real time flexible capacity, enabling the most efficient and accurate transient control of rail pressure combined with the low NVH and optimised efficiency.
