Ricardo: achieving light-duty diesel RDE NOx compliance in urban driving is possible, at a price

Green Car Congress

The SIA conference was focused on clean compression-ignition engines of the future. The vehicles on which the research was based were representative of current production models at the more aggressive end of the downsizing spectrum in terms of engine capacity and output, but modeled with a future three cylinder 1.5 liter diesel engine.

Pinnacle Engine pre-production prototype opposed piston engine shows about 27% fuel consumption improvement across different scooter cycles compared to conventional engine

Green Car Congress

Fuel mass flow comparison shows Pinnacle engine ahead at just about all points in the map. A catalyst could take care of it, but we’ll get a little more efficiency if we get the HCs cleaned up. We did another study with FEV, projecting our data onto a turbo downsized application; we get nearly 50% improvements in common automobiles.
