Ricardo, a global strategic, environmental, and engineering consulting company, has worked in collaboration with Achates Power, one of the world’s leading engine design companies to develop the next generation of opposed-piston gasoline compression ignition engines for light duty vehicles. The multi-phased project (‘BERYL’), funded by the US Government’s Advanced Research Projects Agency-Energy (‘ARPA-E’), aims to create a fuel efficient, lightweight ...
