Cylinder deactivation can reduce NOx emissions through hotter exhaust temperatures and allow more efficient engine operation on fewer cylinders under low-load conditions.
How Optimizing Cylinder Deactivation Cut NOx Emissions 74% in Cummins-Tula Test
Testing of Tula's sophisticated cylinder deactivation control technology on a Cummins engine showed a 74% reduction in nitrogen oxides (NOx) emissions. We talked to Tula's senior engineer about how it works.
