However, diesel technologies have severe environmental impacts.....the engines tend to produce soot, and the soot causes severe medical problems AND causes global warming....the soot from the heavy use of diesels in Asia and Europe creates major local air pollution problems AND causes the Arctic Ocean sea ice to melt.
New scientific research shows that the soot is dispersed globally, and is yet another component of greenhouse warming. The soot also rains out on snowpacks, and Arctic Ocean sea ice, and reduces albedo and augments melting.
The Kyoto Treaty only targets CO2, because European countries rely on diesel and refuse to discuss it, but scientific work shows that diesel is very bad for the climate.
diesel causes global warming and health problems
Crap - last I read the planet is cooling. Beyond that, isn't the planet overpopulated? This moronic set of laws will "save thousands of lives...". Are you sure you want this? (Also, despite Europe's reliance on diesels, aren't they healthier than us? Don't they live longer? If any of that's true the soot problem can't be all that bad...)
A bit more seriously, the new common rail diesels already run pretty clean compared to diesel engines of the recent past. Beyond that, propane injection does wonders to clean up diesel emissions. Doesn't take much propane, and it adds substantial power, too. LNG injection might work just as well. Either would be a hell of a lot less expensive than Kalifornia's heavy-handed approach. (I read the link and note that while fleets are given YEARS to phase in the new requirements, the little guy is screwed - he has to comply immediately. Apparently you only matter if you're big enough to afford a lobbyist. Typical...)
The REAL reason the law would save fuel is that the cost of trucking would soar, and there would be a lot less of it going on! That'll certainly speed the switch to Mexican ports, too, which will really help the employment numbers out there in Kali-land. After destroying their trucking industry, I'd love to see their faces when it dawns on them that everything they wear, use and eat arrives by truck!
The market is already making strides - for example, with tires that have less rolling resistance. The "super single" that replaces dual drive wheels saves a lot on fuel, and I'm seeing more and more of them on the road. As a bonus, the single aluminum wheel and single tire weighs a lot less than the duals used now, so there's less rotational mass. This makes for huge fuel savings with no government enforcers required.
I would have no problem requiring these super singles on all new highway tractors sold, but I have a huge quarrel with retroactively inflicting things like that on the little guy who is already struggling to make payments. (Regardless of where you live, your state DOT is already shaking down truckers in a manner that would do an Illinois Governor proud. In the interest of a few goods continuing to arrive at our stores, let's do away with that extortion before adding any other burdens.)
Back to personal transportation. I like (and would personally prefer to buy) the turbo diesel for it's ready adaptability to bio-diesel fuels, some of which show great promise and realistic EROEI. I also like those little diesels for their high efficiency, torque and durability.
