A cold diesel does require very high compression rates and without a doubt the Chinese engine would burst apart if you raised the compression that high. But a hot diesel engine will run on very low compression rates-- as low as gas engines. That's why a good glow plug like those used on Ford 7.3 liter diesels (Think F-450) or motorized bicycle diesel cars would be needed.
If one can manage the correct air/fuel ratio then smell and smoke won't be a big issue. And if it will run on regular diesel then it will run on bio diesel and will smell like french fries.
Might be just the thing for someone wanting to motorize his or her bicycle catering cart.
