MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control.

MIT team finds aviation emissions’ impacts on air quality larger than on climate

Green Car Congress

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. —lead researcher Dr Sebastian Eastham, from the Laboratory for Aviation and the Environment in MIT's Department of Aeronautics and Astronautics. —Dr Eastham.

MIT autonomous boats can target and latch onto each other: dynamic roboat structures

Green Car Congress

To further that vision, MIT researchers have given new capabilities to their fleet of robotic boats—which are being developed as part of an ongoing project—that lets them target and clasp onto each other, and keep trying if they fail. Moreover, the roboat notices if it has missed the connection, backs up, and tries again.

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). Persistent organic pollutants are chemicals of substantial international concern. The presence of these pollutants in the Arctic is important for several reasons. —Noelle Selin, lead researcher.

Coating developed at MIT could stop buildup of hydrate ices that slow or block oil and gas flow

Green Car Congress

A team of researchers at MIT has developed a coating that could stop the buildup of hydrate ices that slow or block oil and gas flow. through the MIT Energy Initiative. The coated surface attracts liquid hydrocarbons that are already present in the flowing petroleum, creating a thin surface layer that naturally repels water.
