A lot of good points, ArLi. Diesels are great engines, but because of many reasons cited here by you and other readers, diesel engines will displace only a portion of today's gasoline engines. And here's one more reason: You can get only so much diesel out of a barrel of crude. When you tamper with the mix and decide you're only going to extract diesel, you have to do a lot more refining and you create excess volume.

I've thought about a Diesel Hybrid, or even a Diesel Volt

or Diesel VIA where the diesel just runs a generator, but i think external

combustion makes more sense.

@fdos, I can service a gas engine with a carburetor, but an injectin pump is a lot more complex, tighter tolerances all around, and much more highly stressed. And gas piping at 14PSI is a whole lot safer than diesel plumbing at 2500 or more PSI.It is also a lot more forgiving.

I didn't know that about diesel in Europe, ArLi, but I guess it makes sense. I still don't mind having a diesel engine. I guess in terms of its environmental effect, it's not great, but neither are gasoline-powered cars.

Actually diesel fuel is cheaper in Europe because it is "sponsored". I mean petrol prices are artificially high to keep low price for diesel (this movement is initiated by UE and supported by governments).

The only point that automotive companies are promoting small (below 2 liters) diesel engines is their CO2 emission. They just have to pay environmental taxes proportional for CO2 emission from their cars and these taxes rise every year (diesel engines have this emission lower - at least in specs).

From consumer POV it has usually (not always) a little sense to buy a car with small diesel engine. It is because its initial price + maintenance costs + repair costs are much much higher than price for petrol engine. Modern small diesel engines have only one pivot design point - limit CO2 emission. The reliability and operation costs are at the bottom of the priorities list (it is opposite for real "work horses"- diesel engines for trucks, bulldozers etc.)

And a side note about CO2 emission. I have no calculations but IMHO the overall diesel engine emission can be quite comparable to total emission of petrol engine. It is because of increased emission during diesel engine production and during production of required maintenance parts (i.e. DPF).

I can't speak for the repairs, fdos, but diesel engines in general have an initial cost that's about 50% to two times more than their gasoline counterparts, according to David Cole, chairman of the Center for Automotive Research.

Great thought, Cabe. Unfortunately, Volkswagen already beat you to it. The VW XL1concept combines a 47-HP turbo-diesel engine with a 27-HP electric motor.

Sure. Problem is with a diesel and a battery you have a weight and cost adder - twice. Very efficient but I'm not sure how cost effective. I think it's also a marketing problem. To make a rather broad generalization diesel ppl don't like hybrids eg 'Prius repellant' decals on diesel trucks. On the flip side you could argue earthy people don't like diesel because it's fossil fuel and dirty. While practical I think a diesel hybrid is a vehicle both of those camps could dislike.

How about a Diesel hybrid. Get a 10mpg boost in your Prius... Just a thought.

In my experience yes. Diesel cars not as bad. Diesel pickups have gotten very expensive to fix. Deleting all the emissions garbage makes the newer trucks much more reliable and efficient. But delete kits are costly (and only used off highway wink wink).
