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.
