About Common Rail

Common Rail technology is the future of diesel, both in passenger cars and in trucks, buses and most other forms of transportation. The technology appeared first in trucks and buses, but DENSO and other manufacturers since have adapted Common Rail technology to diesel engines for passenger cars. DENSO leads the industry in maximizing the precision of injection timing and quantity. That leadership underlies the systems under development at DENSO to comply with increasingly stringent regulations in Europe and elsewhere. Common Rail technology has bought about huge reductions in exhaust emission levels, vastly improved power and performance levels, greatly reduced engine operating noise levels, and reduced fuel consumption levels to those below that of petrol / hybrid vehicles.

How does Common Rail Fuel Injection Work?

Previously Diesel Fuel Injection pumps not only pressurised the fuel but distributed it directly to the injectors. Common Rail Diesel pumps supply fuel to a “Common Rail” from which the

injectors are supplied fuel at very high pressures (approx. 35,000 psi). Unlike previous injection systems the operation of the fuel injector is not merely controlled by the supply of fuel pressure but electronically using very high solenoid voltages (approx. 185V). All of the functions of the Common Rail system are monitored together with engine and other external factors by a computer which accurately controls the injection process.

Servicing Common Rail

Specialist knowledge is required for the diagnosis and repair of this technologically advanced fuel system. In order to produce such high injector pressures the system components are manufactured to very small tolerances, demanding the use of a pressurised “clean room” with highly effective filtering system for all assembly work. Because of its commitment to Common Rail Technology Diesel and Turbo Wellington has been recognised by Denso as the ONLY company in New Zealand to  their Premium Dealer.
