Researchers Tout Highly Efficient 2-Stroke, 2-Cylinder Engine
Scientists at the Valencia Polytechnic University in Spain say the little 2-cylinder, 2-stroke diesel they have developed is significantly more efficient and half the weight of a conventional 4-cylinder unit.
Scientists at the Valencia Polytechnic University in Spain say the little 2-cylinder, 2-stroke diesel they have developed is significantly more efficient and half the weight of a conventional 4-cylinder unit. Yet it delivers nearly the same performance as the larger powerplant.
The 730-cc engine features low-temperature homogenous combustion, valve scavenging and 2,000-bar fuel injection.
The 2-stroke diesel project is part of POWERFUL, a European research effort among engineers in the Czech Republic, France and Spain. Their aim is to develop ultra-efficient engines for use in A- and B-segment vehicles.
Renault SA is coordinating the project, which also is developing a low-cost four-stroke 2-cylinder engine and a four-stroke, 3-cylinder engine capable of burning multiple fuels.

Jeeps Modified for Moab
On Easter morning in Moab, Utah, when the population of that exceedingly-hard-to-get-to town in one of the most beautiful settings on Earth has more than doubled, some people won’t be hunting for Easter eggs, but will be trying to get a good look at one of the vehicles six that Jeep has prepared for real-life, fast-feedback from the assembled at the annual Easter Jeep Safari.
