Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

The path to realizing the goal is to build on the strong legacy of fuels and engines work sponsored by the vehicle and bioenergy technologies offices over the past several decades. High combustion noise and high HC and CO emissions are also a problem, with lower exhaust temperatures representing a challenge for current emissions controls.
