To achieve further CO2 reductions, OEMs
will retain boosting/turbocharging in
future engine designs.
Effects on Engine Performance
A multi-faceted hurdle to engine performance.
Expected to worsen with even higher output engines
No drivers to revert back from
turbocharging to naturally aspirated
engines.
Functional Fuel essential with this
approach.
OEMs continue development of further
downsized, higher output engines.
Performance parameters may further increase
in severity and frequency in further downsized
engines.

Fuel Additives Are Enabling An Evolution inFuel
and Vehicle Technology
Emission control and energy conservation policies are drivers for change
Particle emissions remains a challenge
Vehicle technology and test cycles have significant impact on
particulate emission
Clean Fuel solutions are complicated and are exemplified by biofuels
Fuel additives enable the safe and efficient production, transport and
utilization of fuel
Fuel additives maintain optimal vehicle performance
Fuel additives offer potential for fuel efficiency and emissions
improvement
Fuel additives provide means to effectively and efficiently modify fuel
properties
Maintain optimal engine performance and reduce emissions
Higher additive treat rates may be necessary for optimal vehicle performance
