Common Rail Specialists
A Common Rail engine is designed to supply constant fuel pressure to electronically controlled injectors though a shared fuel rail. This means the fuel supply is not dependent on the engine revs.
A common rail system is built around four basic components:
- A high pressure pump with pressure regulator and inlet metering value.
- A rail which contains a pressurised reserve of fuel.
- Injectors which inject precise amounts of fuel into the combustion chamber as required.
- A Diesel Control Unit – the ‘brain’ of the system, which precisely controls injector flow and timing as well as rail pressure while continuously monitoring the operating conditions of the engine.
Our new BOSCH DCI 700 - Common Rail Injector Testing
Precision to protect us for the future.
The latest exhaust emission standards and future directives increase the significance of testing common rail injectors in modern diesel engines.
Therefore, the more precise the measurement is, the more accurately the injector can be adapted to perform at its maximum efficiency.
Our solution: the new DCI 700 diesel test bench from Bosch effectively secures a competitive advantage for our workshop today and for years to come.
With its new high-speed precise measurement system, the DCI 700 has reduced setup and test times as well as user-friendly operation.
Up to 70 % shorter test times: mounting and demounting of a set of standard injectors within five minutes and an average of 15 minutes testing time, Higher quality, reliability, and transparency for Bosch injectors thanks to fast and precise testing, including IMA/ITA/NIMA coding.
Common Rail testing
A fundamental change
Common Rail systems are already fitted to many Ford, Renault, Kia and Hyundai vehicles and many new applications are planned for the near future.
Delphi has been involved in the development of Common Rail technology from the beginning. Some of the first systems were pioneered by Lucas Diesel Systems and Delphi has inherited this expertise.
Common Rail marks a fundamental change in diesel technology and is happening now.
More and more vehicles are being introduced with Common Rail systems. It is calculated that 70% of new diesel vehicles will incorporate Common Rail injection systems and 5 million such systems will already be on the road.
