INDUSTRY AT A GLANCE
Commercial trucking diesel engine manufacturers know how critical it is to secure both greater fuel efficiency and reduced NOX emissions
The standard diesel engine offers clear fuel consumption advantages vs. the gasoline engine, though it suffers from significant emissions challenges, especially NOX.
Meeting global regulations will require implementing advanced solutions — dDSF is the only technology that simultaneously improves fuel efficiency while reducing both CO2 and NOX emissions.
dDSF test results show NOX reductions of 66% are achieved relative to the baseline system with a 4% CO2 reduction
No other diesel solution offers both greater fuel savings and decreased NOX tailpipe emissions – at the best value in the industry
What is dDSF?
Like DSF for gasoline engines, dDSF uses individual cylinder deactivation control strategies to meet torque demand at optimal fuel and aftertreatment efficiency
Key solution components include:
- DSF Valvetrain: Individual cylinder deactivation capability
- Engine controller with dDSF: Tula’s proprietary controls strategies for smooth, efficient operation and fuel economy gains
- dDSF offers the opportunity to decreased after-treatment costs
- Additional synergies can be gained by coupling dDSF with hybridization
How does dDSF work?
Tula’s dDSF is a unique solution in the diesel industry, providing both fuel/CO2 savings and NOX improvements at an industry leading value to cost ratio
The advantages of dDSF over static cylinder deactivation (CDA) are more than just CO2 and NOX reduction. dDSF also enables smoother transitions for reduced noise and vibration, and also distributes the firing of cylinders uniformly to reduce uneven engine wear.
