lists and explains a lot of the inherent problemes in trying to make diesel engines more popular.
However, I would like to add one aspect to it:
Gas-engines (at least the ones of the "american iron type" with pushrods, 2-valve-heads, regular-non-adjusting camshafts etc.) are cheaper than diesels (which have to apply expensive technology in order to meet emission control regulations)
True.
But:
I think the picture would be different, if "emissions" would include a larger portion of
all the emissions a vehicle generates (may be even evaluating a "typical" life cycle of the product) - e.g. carbon dioxide (equivalent of the amount of fuel burned).
If CO2 would be part of the equation - and it clearly is an (harmful) emission - the gas engine would be evaluated in a more fair way:
It would then have to meet tougher, yet fairer standards that ultimately require the reduction of fuel consumption.
A good example are electric hybrids: potentially effectiv (when applied in a lot of stop-and-go traffic) but expensive - similar to an diesel
Long story short:
Emissions control regulations are not really fair to the diesel (IMHO)
I would like to include CO2 into the view while keeping up the established high standards:
Et Voilá - a much more even race
Finally one
question to the potential customers in the US:
Would you require the "new small diesel" to be a V8?
I think a V6 would be cheaper and at this size perfectly fine, right?!
No?!
Comments pls...
