Study finds Tula dDSF software reduced NOx 41% and CO2 9.5% in Leibherr D966 diesel

Green Car Congress

Based on simulations, Tula’s diesel Dynamic Skip Fire (dDSF) software ( earlier post ) allowed the reduction of NO x tailpipe emissions by 41% and CO 2 by 9.5%. 6-cylinder diesel engine, will also be used in further tests. Liebherr D966 inline engine tested with Tula’s diesel Dynamic Skip Fire software.

JATO: European new car CO2 emissions highest average since 2014; shift from diesel to gasoline and SUVs rise

Green Car Congress

An analysis by JATO Dynamics has found that average new vehicle CO 2 emissions in European increased in 2018, with the total average increasing by 2.4 g/km in 2018—the highest average of the last four years. At the same time, the sales growth of diesel cars fell from +7% to +1%. g/km to 120.5 g/km in 2015 to -1.4

EEA final data shows average car CO2 emissions in Europe kept increasing in 2019

Green Car Congress

Key reasons include the growth in the sport utility vehicle segment and an increased average mass. Most new SUVs registered were gasoline vehicles, with average emissions of 134 g CO 2 /km, which is around 13 g CO 2 /km higher than other new gasoline cars. Diesel vehicles constituted 31% of new registrations. g CO 2 /km.

JATO: new car average CO2 emissions highest in Europe since 2014; slow EV uptake insufficient to counter fewer diesels and more SUVs

Green Car Congress

As expected, the combination of fewer diesel registrations and more SUVs continued to have an impact on emissions. g/km higher than in 2018, the delta was lower than the difference between the 2017 and 2018 results—where the growth was 2.4 The average emissions of electrified vehicles, was 63.2 —Felipe Munoz.
