Pumpe-Duse diesel technology as against better known CRDi

Some Points about PD tech.

1. Better emissions (Even at low idle). Uses a part called STC for better emissions at low idle.
2. PD Tech is basically used for heavy diesel engines. Cummins is using this Tech in INDIA for its K & V series Engines.
3. Advantage for this Tech is basically Excellent torque & better emmisions.
4. Disadvantage :- Basically a mechanical process. Not too much of electronics involved.

I am not a tech wizard and do not much know the technological advantages of one over the other but I know this, newer is not always better. Manufacturers often push something down our throats saying "it is latest" which actually means " hey dumbos, this is cheaper and easier for us to manufacture." And we buy their stories hook, line and sinker. Why am I saying this? Because there is an Octavia TDi one of my relatives has. It's not CRDi and heck it's not even PD, but who cares. It's an '03 model car and is nearing 4 lakhs. Still runs like new and flies on higways. Try pushing a PD or CRDi to 4 lakh Kms. They shine for 1st 1 lakh Kms and thereafter start disintegrating. So much for technological advances. I think these are primarily use and throw engines.
