Other Applications of HCCI Research
To date, there have been few prototype engines running in HCCI mode; however, the research efforts invested into HCCI research have resulted in direct advancements in fuel and engine development. Examples include:
- PCCI/PPCI combustion - A hybrid of HCCI and conventional diesel combustion offering more control over ignition and heat release rates with lower soot and NOx emissions.
- Advancements in fuel modelling - HCCI combustion is driven mainly by chemical kinetics rather than turbulent mixing or injection, reducing the complexity of simulating the chemistry which results in fuel oxidation and emissions formation. This has led to increasing interest and development of chemical kinetics which describe hydrocarbon oxidation.
- Fuel blending applications - Due to the advancements in fuel modelling, it is now possible to carry out detailed simulations of hydrocarbon fuel oxidation, enabling simulations of practical fuels such as gasoline/diesel and ethanol. Engineers can now blend fuels virtually and determine how they will perform in an engine context.

Famous quotes containing the word research:
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
