The usual suspects are particulates from diesel combustion and dust mites.
In 1913, Rudolf Diesel, French inventor of the diesel internal combustion engine, disappeared and presumably drowned in the English Channel.
Especially difficult to find are folks who can do diesel-engine combustion analysis and electromechanical-controls engineering.
Other projects financed by the VC fund: In BorgWarner's engine division engineers are working on strategies to optimize airflow in diesel engines for more efficient combustion.
And we are currently developing a wide range of advanced technology vehicles, including more hybrids, more diesel engines, hydrogen internal combustion engines and even fuel cells later on down the road.
Also, the cleaner burning fuel reduces combustion byproducts over petroleum and diesel, cutting carbon monoxide emissions by an estimated 90%-97%, and nitrogen dioxide emissions by 35%-60%.

Now, it's true that amazing gains are being made in the efficiency of internal combustion engines, both gas and diesel: direct injection, cylinder deactivation, stop-start, eco-mode throttle mapping, to name a few of the recent applied technologies.
First, when released into the air as a result of incomplete combustion (from sources as varied as badly serviced diesel engines and forest fires), soot particles absorb sunlight, and so warm up the atmosphere.
In contrast, reducing emissions of the sooty particles known as black carbon, which are given off by inefficient combustion in cooking fires and brick kilns, and by dodgy diesel engines, offers rapid, huge and tangible public-health benefits (see article).
The combustion is slow and rich, using just enough oxygen to bust apart the diesel molecules into hydrogen and carbon monoxide without burning off the diesel entirely.
