It's obvious that the two-stroke isn't the root of all environmental evil, but that doesn't exactly mean it's doing cleansing work, either. I'd like to hear the Mad Scientist explanation for the blue haze that hovers over cities in SE Asia, which was notably reduced when the government decided that 4T was the law.
And don't think JETZ is getting soft here, because I should note that this move utterly destroyed the local economy, as no one could afford the maintenance or the "upgrade" itself, in spite of being forced to do so. The EnviroFit solution, which retrofitted the 2T to DI, proved not only to be cheaper than a regular 2T in the long run (fuel savings) but also cleaner than a 4T. But the fact remains, the old conventional 2T left a haze, the DI and 4T did not, or at least not to nearly the same extent.
HOWEVER!!! I think this point might actually be mute in the future. I present to thee, the future of fuel, algae! All the carbon in algae-based fuels must first be sucked out of the atmosphere, making an algae fuel (in theory) carbon-neutral. And because the raw product is virtually identical to crude, your resulting fuel is nearly identical as well, meaning that no modification of the engine is required. Above everything else, I think this path should be pursued most vigorously, because it would put an end to 100% of these little fuel usage and emissions debates.
Sorry for the rant, but I'm rather passionate about the algae.
