Default A small difference between DDiS and 1.3 MJD.

I just observed an interesting thing...

The fiat 1.3 JTD (MJD) multi-jet direct injection system is supplied with fuel via a common-rail system at a pressure of 1600 bar, whereas in SWIFT DDiS it is 1400 bar (Taken from Swift Brochure).

How it happened? Any clues?

Where did you get the specs for Fiat 1.3 MJD from? Can you post it here?

Dont Worry, wait for the 1.3 MJD application of the Palio to hit the roads, you could see a reduction in the boost pressure of that as well. For indian condition cars are detuned.

Can a remap of the engine increase the pressure?

Or will the pump itself be different.

What difference does this pressure difference make on the road ?

Something more about the engine that I learned yesterday. The rocker arms of the car made brittle. The rocker arms would break away thereby saving your valves from bending. I don't have much technical detail but was taught this by guys who underwent training at Fiat Ranjangaon before the Palio 1.3 MJD was launched.

Why would they break i.e.under what circumstances have they provided this so-called safety feature.

To prevent hydrostatic lock, in event of the engine sucking in water while negotiating a waterlogged area. Its better to break the rocker arm than break everything else.

More compressed fuel means efficient burning which converts to more fuel effiency.
