Jacobs latest engine technologies cut emissions and fuel use while providing drivers with much smoother stops and starts.

Cummins Inc. and Tula Technology, Inc., a leader in propulsion efficiency, announced at SAE International’s WCX the results of their collaborative study on the effectiveness of Tula’s diesel Dynamic Skip Fire (dDSF) in reducing nitrogen oxides (NOx) and carbon dioxide (CO2) emissions on a Cummins X15 HD Efficiency Series diesel...

Cummins, Tula Demonstrate Emission-Reducing Diesel Technology April 13, 2021 Cummins Inc., a corporation of business segments that design, manufacture, distribute and service power solutions, and Tula Technology Inc., a company that specializes in propulsion efficiency, have unveiled the results of their collaborative study on the effectiveness of Tula’s diesel Dynamic Skip Fire (dDSF) in reducing nitrogen oxides (NOx) and carbon dioxide (CO2) emissions on a Cummins X15 HD Efficiency Series diesel engine. Low-load cycle performance was estimated with a well-calibrated powertrain simulation ...

The clock is ticking for trucking manufacturers to meet challenging new emissions requirements in 2024 and 2027. On those two horizons are reductions of NOx by up to 90 percent, CO2 by up to 25 to 30 percent plus new low load cycle and in-use specifications, as Eaton makes clear in a video on diesel cylinder deactivation (CDA). This emerging technology holds real promise in reducing emissions while improving fuel economy, but it’s the emissions battle that’s really taken center stage and driven the formation of various partnerships. Eaton has worked with Cummins to test CDA in a Cum...
