Their paper is published in the International Journal of Engine Research. However, if an engine has to switch to conventional diesel combustion (CDC) operation during high engine loads, the engine out NO x will be very high and quickly can degrade the NO x reduction potential of a multi-mode RCCI strategy, they found.

Representation of the limited operating range of robust HCCI operation in a conventional 4-stroke SI engine. Broadening LTHR and HTHR, and reducing the maximum rate of pressure increase during LTHR and HTHR, increases the operating range of a HCCI engine. The team explored the configurations in a single-cylinder four-stroke engine.
