New Engine Designs Present New Challenges

New downsized engine designs deliver superior performance

Direct injection exposes injectors to more severe operating conditions

Hetergeneous/stratified air-fuel mixtures produce higher particulate emissions

New engine designs are prone to LSPIat low-speed,high-load conditions

New challenges also present new opportunities for fuel additives

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.
