    So what's the difference between the "old" dp-diesel and the new common rail version. (Please don't say the injection system!) I would have expected more power and torque, yet the figures are identical. ??

    Modern diesels owe their resurgence in popularity to advances in fuel delivery and engine management systems that allow the engines to return power, performance and emissions equivalent to their gasoline counterparts, while simultaneously producing superior fuel economy.

    It's the high pressure fuel rail and the computer controlled electronic injectors that make all the difference. In the common rail system, the fuel pump charges the fuel rail at a pressure of up to 25,000 psi--but unlike indirect injection pumps--it is not involved in fuel discharge. Under the control of the onboard computer, this fuel quantity and pressure accumulates in the rail independently of engine speed and load.

    Each fuel injector is mounted directly above the piston within the cylinder head (there is no pre-chamber) and is connected to the fuel rail by rigid steel lines that can withstand the high pressure. This high pressure allows for a very fine injector orifice that completely atomizes the fuel and precludes the need for a pre-chamber. The actuation of the injectors comes via a stack of piezo electric crystal wafers that move the jet needle in tiny increments allowing for the spray of fuel. Piezo crystals function by expanding rapidly when an electric charge is applied to them. Like the fuel pump, the injectors are also controlled by the the engine computer and can be fired in rapid succession several times during the injection cycle. With this precise control over injector firings, smaller, staggered quantities of fuel delivery (5 or more) can be timed over the course of the power stroke to promote complete and accurate combustion. In addition to timing control, the short duration, high pressure injections allow a finer and more accurate spray pattern that also supports better and more complete atomization and combustion.

    Through these developments and improvements, the modern common rail direct injection diesel engine is quieter, more fuel efficient, cleaner, and more powerful than the indirect mechanical injection units they have replaced.

    From a sales point of view to Joe public that is probably the single biggest improvement. No more clack, clack I'm a diesel as you drive into a friends drive.
    A mate of mine who is dyed in the wool petrol head (V8's and turbos for the last 20 years) has just brought himself an A4 DSG with the 103CR engine and he absolutely loves it. He's told me for years I'm stupid driving diesels then he came back from a drive to central Vic the other day telling me how great the overtaking was at 120+ plus was on his new car. I think going two weeks before his first fuel top up had a lot to do with his change of heart as well.

    Mind you... just look at the single engine in the Otello which is the Carrier bringing a few of the forums users cars in Early Nov...
    The
    main engine is a B&W 7S60MC-C directly reversible marine
    diesel with constant pressure supercharging and a
    maximum output of 21,490 BHP at 105 RPM.

    Mind you the engines the size of a double decker bus

    Hahaha, that is awesome.
    Imagine seeing a dyno plot for that thing.

    Are new arrivals 103TDI CR?

    Just a query if new arrivals 103TDI are now all common rail. Thinking seriously of getting the Octavia Scout and would prefer CR.

    Have read several reviews etc, all most positive, but no mention if CR.

    probably not as cut and dried as with VW's. VAG have a history of getting rid of old engines in other marques.

    if you go to the dealer, ask what engine codes are on offer.... then all you need to do is a quick google search and you'll find out:

    Yep all the new arrivals are common rail. The switch to CR wasn't really listed by Skoda Australia when it arrived so the reviews wouldn't really mention it anyway.
