One Technology

PERFORMANCE� Wide range of specific output

� Very high specific output

� Increased knock tolerance

� Increased compression ratio

� Maximum charge cooling

� Boosting synergies

���� DIRECT INJECTION

FUEL FLEXIBILITY

� Cold start with low volatility fuels

� Maximum benefit for every fuel type

� No power loss with gaseous fuels

� Operation with hydrogen rich gases

� SI combustion of heavy fuels

� Differential stratification of fuel types

���� DIRECT INJECTION

EMISSIONS

� Cold start with low volatility fuels

� Lean stratified starting

� Lean after start operation

� Extreme fast catalyst light off

� No intake port fuel film

� Reduced catalyst loading

���� DIRECT INJECTION

EFFICIENCY� Increased compression ratio

� Aggressive engine downsizing

� Highly dilute & lean operation

� Homogeneous & stratified combustion

� Unthrottled operation

� HCCI / CAI controllability

The Way Ahead

THE INTERNAL COMBUSTION ENGINE HAS A LONG LIFETIME.

GLOBAL REQUIREMENTS ARE DIVERSE. FUTURE FLEXIBILITY

MUST BE BUILT INTO FEW ENGINE PLATFORMS.

NEW ENGINE PLATFORMS REQUIRE INNOVATION NOW TO

ENSURE SUSTAINABLE COMPETITIVE ADVANTAGE.
