Biodiesel is sulphur-free too. IIRC the main advantage of ethanol is a decrease on the emission of particulate matter due to its easier vaporising and nitrogen oxides due to its colder burn.

Yes.

It does beg an interesting question though; why haven’t we added gas derived camshaft technology to Diesel engines? Variable timing/lift?

Because in cars diesels are a luxury item 10-30K extra up front Plus diesel maintenance parts DPF,DEF ,EGR , SCR, and regens that move the $.01 per mi much closer to a gasser . Diesel is thrown in to improve Cafe scores and 3/4 + pickups aren't counted towards the cafe score. This is starting to change with the reintroduction of the diesel coming back to the cafe scored halfton and down trucks.

As I finished reading this thread , I was pondering a way to use oil pressure to change the index of the cam in relation to the gear (old gear drive on my Cummins). Twin cams would be the way to go.

It's already fitted to some light-duty Diesel engines, even though they're not available in the U.S. and Canada.
