INDUSTRY AT A GLANCE
Forward-thinking automakers and automotive suppliers know how critical it is to secure greater fuel economy.
Meeting global mandates will require implementing advanced combustion technologies, from Miller-cycle engines to electrification and autonomous technologies.
As the industry evolves, the hybrid – a combination of electrical motor and internal combustion engine – is forecast to be one of the industry’s widely used approaches to improving fuel economy.
eDSF (DSF® plus electrification) is proven to work synergistically with existing 48V hybrid technology, resulting in an expanded DSF operating range and longer braking energy regeneration.
eDSF more than doubles the fuel efficiency of 48V while lowering the cost per percent improvement.
No other fuel efficiency solution offers greater gains at a lower cost.
The synergies between eDSF and 48V mild-hybrid dramatically boost fuel efficiency while lowering costs per percent improvement.
What is eDSF?
eDSF couples DSF with vehicle electrification to increase the operating range of DSF.
Key solution components include:
- 48V+ hybrid vehicle architecture with an integrated belt starter generator
- High response inverter: Synchronizes e-motor with cylinder firing in Skip Fire Operation
- DSF Valvetrain: Individual cylinder deactivation capability
- Engine controller with eDSF: Tula’s proprietary SW synchronizes DSF and the hybrid system for smooth, efficient operation and fuel economy gains
How does DSF work in tandem with Electrification?
Torque Pulse Smoothing
eDSF uses the existing hybrid motor to smooth torque pulses of skip fire operation, extending
the range of useful firing densities and reducing vibration.
