Thank you for contributing

True.

Not quite true. The maximum efficiency of any engine is given by the following equation that stems from Carnot's theorem (http://en.wikipedia.org/wiki/Carnot_engine):
max efficiency = 1 - (Tc/Th)
Where Tc is the absolute temperature of the cold reservoir and Th is the absolute temperature of the hot reservoir. The operating temperature of a diesel engine is about 550 C (http://en.wikipedia.org/wiki/Diesel_engine#Early_fuel_injection_systems), so when discharging to ambient conditions the maximum efficiency is:
max efficiency = 1 - (298 K / (273 K + 550 K)) = 63.7%
So a perfect thermodynamically efficient diesel engine already leaves a significant amount of energy in the off gases.
* Organic molecules are electrically inert and won't be excited by an outer electrical field.
Most organic molecules in oily chemicals, especially the types used in fuel, are non-polar. However, viscosity is produced by electrostatic interactions between sub-atomic particles, manifesting in the resistance to shear stress. An electric field will most definitely have an effect on this property, whether the molecules are polar or not.

Apparently, this article was published in
Energy & Fuels in 2008. Here's the link to the published article at the bottom of the page: http://pubs.acs.org/cgi-bin/abstract.cgi/enfuem/asap/abs/ef8004898.html
I think you can purchase a PDF of the article there if you want to.
