The internal combustion engine is a chemical process, not a thermodynamic cycle, Foster said, and all of the energy in the fuel is theoretically available to be converted into work. If that is the case, why do we fall so short? Well, the engine processes are not ideal. Two concepts need to be kept in mind. Liquid Piston.

One high-efficiency combustion concept under investigation is gasoline compression ignition (GCI)—the use of gasoline-like fuels to deliver very low NO x and PM emissions as well as high efficiency in a diesel compression ignition engine. The commercially available gasoline base had an octane number of 87.

General Motors last week again highlighted the progress it is making with advanced HCCI (homogeneous charge compression ignition) gasoline engines by showcasing a demonstrator unit. Najt, then at the University of Wisconsin, and David Foster published the first study of a gasoline-fueled four-stroke HCCI engine in 1983.).

Wisconsin Engine Research Consultants LLC. This project will enable diesel-like efficiency and increased maximum power output in a gasoline engine by using a secondary fuel to suppress engine knock under high load. Increased availability of magnesium can enable vehicle weight reduction and improvement in fuel efficiency.

Selected projects, by size of award, are: State of Wisconsin’s Wisconsin Clean Transportation Program. The project will result in expanded availability of alternative fuels with 17 new CNG and E85 fueling stations and 63 electric vehicle charging stations. Total DOE award: $14,999,658. Total DOE award: $14,983,167.

Unlike ethanol, isobutanol can be blended at any ratio with gasoline and should eliminate the need for dedicated infrastructure in tanks or vehicles.

A team of researchers led by James Dumesic and George Huber, both now at the University of Wisconsin-Madison, have demonstrated how C 5 sugars derived from hemicellulose can be converted into a high-quality petroleum refinery feedstock via a four-step catalytic process.

Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. It is much more than that. Table of Contents.

Johnson said that currently, Achates can deliver a 12-16% reduction in fuel consumption compared to the best diesel, and about 50% against gasoline, and with a cost and size reduction. When we do that, then the thing is how much fuel efficiency can we demonstrate versus a relevant comparator. —David Johnson. The Achates engine.
