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

Green Car Congress

JUNE 11, 2016

The SIA conference was focused on clean compression-ignition engines of the future. Future RDE emissions legislation and fleet average CO 2 targets represent a challenge for automakers wishing to provide cost-effective light duty diesel vehicles. The cost comparison is with respect to a Euro 5 baseline. liter diesel engine.

As a point of comparison, the US EPA’s proposed national CO 2 emissions standards for light-duty vehicles under section 202 (a) of the Clean Air Act would require these vehicles to meet an estimated combined average emissions level of 250 grams/mile of CO 2 —155.26 g/km—in model year 2016.

GFEI report finds improvements in average new LDV fuel economy lagging pace required to cut 50% fuel use for new cars worldwide by 2030; policy focus should be on emerging markets

Worldwide, light-duty vehicle (LDV) fuel economy is not improving fast enough to cut average fuel use by 50% for all new cars by 2030, according to a working paper issued by the Global Fuel Economy Initiative ( GFEI ). —“International comparison of light-duty vehicle fuel economy”.

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.

Compared to new diesel engines, the Delphi team found that BSFC for GDCI at light loads was comparable or better, and at high loads was about 5% higher. They found that at all loads, GDCI was remarkably clean, with the potential for no aftertreatment for NO x and particulate emissions. —Sellnau et al.
