Introduction & Background
The objective of this report is to evaluate the impact ofdifferent technological advancements on fuel consumptionimprovements. The report further analyses the comparisonbetween the results from VOLPE and Argonne NationalLaboratories (Autonomie).
Calculation
Following is the detailed calculation process considered duringthis study:
The reference technology was considered to be the root ofeach of the respective technology trees from VOLPE and IAV
The reference fuel consumption was computed to be the fuelconsumption corresponding to the reference technology
Each of the fuel consumptions corresponding to theadvanced technologies were computed to be compared tothe reference fuel consumption.
Absolute % increase in fuel consumption:
Reference Fuel Consumption −Current Fuel Consumption
Reference Fuel Consumption%
Incremental % increase in fuel consumption:
Previous Tech. Fuel Consumption −Current Tech. Fuel Consumption
Previous Tech. Fuel Consumption%

Engine Technology Descriptions
Eng1 - gasoline, 2.0l, 4 cyl, NA, PFI, DOHC, dual cam VVT
– Calibrations fully optimized for best bsfc and maximum torque (comb. phasing, valve timing, lambda, etc)
Eng2 - VVL system was added to the intake valves on Eng1
– Valve lift and timing optimized
Eng3 - Eng2 (PFI) converted to direct injection
– Comp ratio raised from 10.2 to 11.0 and injection timing optimized
Eng4 - Cylinder deactivation added to engine Eng3
– Engine fires only 2 cylinders at low loads and at speeds below 3000 RPM by deactivating valves on 2 cylinders
Eng5a - Eng1 converted to SOHC (gasoline, 2.0l, 4 cyl, NA, PFI, single cam VVT)
– Valve timing optimized for fixed overlap camshaft with standard friction model from DOHC concepts
Eng5b/ Eng6a/ Eng7a/ Eng8a - Reduced friction from Eng5a/ Eng2/ Eng3/ Eng4 respectively
– Engine FMEP reduced by 0.1 bar over entire operation range to understand friction benefit from SOHC
Eng5c/ Eng6b/ Eng7b/ Eng8b - Reduced friction from Eng5a/ Eng2/ Eng3/ Eng4 respectively
– Engine FMEP reduced by 25% over entire operation range to understand potential of ‘extreme’ friction reduction (this is a “what if” study which doesn’t necessary represent what is currently possible)
Eng12 - gasoline, 1.6l, 4 cyl, turbocharged, DI, DOHC, dual cam VVT, intake VVL
– Calibrations fully optimized for best bsfc (comb. phasing, valve timing, lambda, etc)
Eng13 - Eng12 downsized to 1.2l
– Turbocharger maps scaled to improve torque at low engine speeds
Eng14 - High pressure cooled EGR added to Eng13
– Cooled EGR target set points optimized
Eng15 - Eng14 downsized to 1.0l
– Cooled EGR target set points re-optimized and turbocharger maps re-scaled
Eng16 - Eng15 converted to 3cyl, 1.0l concept
– Intake and exhaust piping scaled to account for larger mass flows through each cylinder and cooled EGR target set points re-optimized
