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.
4. Features
48 v mild-hybridization applied to 1.5L diesel
comprising of
12.5 kW 48V belt starter generator
48V low cost advanced lead-acid battery
48V electric auxillaries
48V electric turbine
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.
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.
