common rail V injector pump

[jak]

can anyone tell me on a one to ten scale
for power, torque etc
how much better is common rail than pump

cheers lads

Think you will need to explain with some more detail......

common rail diesel injection systems still require a pump to provide pressure (up to 1,600 bar in newer motors).

common rail engines are usually 'overseen' by some kind of ecu: injector opening times, fuel metering etc is varied in much the same way as with petrol engines, ie lots of variability.

in most (but not all) cases, common rail provides a lot more torque, power and economy - along with a reduction in noise and emissions.
