The challenge today is that reductions in all three areas must be achieved – to the tune of an additional 90% reduction from 0.2 ppm to 0.02 ppm in NOx and a 25% reduction in CO2 from Phase 1 ...

By using NTRM bottles, proper calibration is assured by maintaining NIST traceability. When setting up a system, an important consideration of using calibration cylinder is the lead time required.

The company will not certify engines at the 0.2 gram NOx level required for 2010, but rather use emissions credits generated by high volumes of light- and medium-duty diesel engine sales over the ...

Emissions Reductions Impending emissions legislation in North America (EPA 27) and Europe (Euro 7), which covers both NOx and CO2 emissions, are pushing engine designers harder than ever before in ...

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 ...

Cylinder deactivation is nothing new for Tula. General Motors has used the Silicon Valley-based company’s Dynamic Skip Fire software to cut emissions and improve fuel efficiency by as much 15% ...

During computer testing, the Cummins X15 engine running with Dynamic Skip Fire showed reductions in NOx emissions ranging from 45% to 66%, and CO2 reductions of 1.5% to 3.7%.

CARB will require a reduction in NOx both for the steady-state highway test and for the low-load test that also measures vehicle operation in a mixed highway cruise and stop-and-start environment.

Recent demonstrations in regulatory test cycles and real-world drive cycles have proven that Eaton’s cylinder-deactivation (CDA) technology can play a key role in helping commercial vehicle ...

This study was conducted to develop an understanding of how rate-shaped and split injections can affect the soot and NOx emissions of a heavy-duty diesel engine. The tests were performed on a single ...
