In order to maintain correct operation of the Common-Rail system both high and low pressure systems need to function correctly.

The Lehnert Universal Common-Rail Test Kit is an efficient and easy means by which to check the system pressures.

High quality gauge sets and hose adaptors with quick fit couplings are used and with the kit designed for use on vehicles such as Nissan, Mazda, Hyundai, Fiat, Citroen, Iveco etc. this tool kit represents both quality and diversity.

A possible source of a malfunction with the Common-Rail injection system can be a defective high pressure injector.

The Lehnert Universal Common-Rail Test Kit includes high quality plexiglass graduated cylinders and a coupler set.

Testing fuel flow and comparison of individual injector fuel return flow rates is quick and simple and an injector failure can be readily diagnosed by reading off the fuel return levels in the scaled plexiglass cylinders.

Today the Common-Rail system has brought about a revolution in diesel engine technology. Different automobile makers refer to their Common-Rail engines by different names:

• DaimlerChrysler - CDI (and on Jeep vehicles simply as CRD)
• Fiat Group - (Fiat, Alfa Romeo and Lancia) - JTD
• Honda - i-CTDi
• Hyundai - CRDI
• Ford Motor Company - Duratorq and PowerStroke
• Renault - dCi
• General Motors/Opel Vauxhall - CDTi (most of these engines are manufactured by Fiat and Isuzu)
• Mitsubishi - DI-D
• PSA Peugeot Citroën - HDI or HDi
• Ssangyong - XDi (most of these engines are manufactured by DaimlerChrysler)
• Toyota - D-4D
• Nissan - NEO-Di
• Mazda - CiTD
• Tata - DICOR
• Mahindra - CRDe
