The document proposes an Advanced Diesel Electric Power Train (ADEPT) concept that uses intelligent electrification to reduce CO2 emissions in diesel vehicles. It features a 48V mild-hybrid system with a belt starter generator, battery, and electric auxiliaries and turbine. This system allows for improved start-stop operation, regenerative braking, and optimized ancillaries like pumps. It also includes a turbine that recovers exhaust heat and applies it as torque. Testing confirmed the ADEPT concept reduced fuel consumption by 10-12% and CO2 emissions below 80 gm/km.

2. Abstract
The Advanced Diesel Electric Power
Train(ADEPT) combines low-cost technologies
with a high degree of synergy to reduce current
class-leading C-segment CO2 emissions by a
further 15-20%.
it also aims to apply low voltage concept of
“Intelligent Electrification” in a diesel engine.

3. Introduction
The ADEPT concept features intelligent
electrification to deliver a very low CO2 mild-
hybrid diesel C-segment vehicle.

6. 48V Belt Starter Generator
• Improved start - stop operation.
• Regenerative braking
• Torque assist
• Efficient electrical generation

7. 48V Electric Ancillaries
48V electric coolant pump.
48V electric oil pump
• Efficiency improvements from optimized flow
and pressure control
• Use of regenerative braking energy for further
fuel savings.

8. 48V Electric Turbine
• Located downstream of standard turbocharger.
• Capture exhaust waste heat for reapplication as
torque on crankshaft.
• After treatment thermal management.
• TIGERS

9. TIGERS
• Turbine Integrated exhaust Gas Energy
Recovery System
• Uses the same switch reluctance technology for
speed start-stop systems and electric
supercharging.
• It helps in returning the recovered heat from
power train to crankshaft.

10. TIGERS

11. Prediction
• Intelligent electrification will offer extremely
cost effective reduction of CO2emissions and
improved fuel economy.
• Less than 70 gm/km CO2 emission will be
reduced .

12. Result
• The final testing results of its ADEPT 48 V diesel
hybrid power train concept, confirming a 10-12%
reduction in fuel consumption – equivalent to
CO2 emissions below 80 gm/km.
