CR Gasoline, in which gasoline was injected through the higher-pressure common rail injector, allowing for much later injections of large quantities of gasoline. This allows for stratification of the gasoline charge before any diesel is injected. One caveat is that the CR Gasoline case was not optimized.

Among their findings were that multi-mode RCCI has the potential to offer greater than 15% fuel economy improvement over a 2009 gasoline PFI baseline over many light-duty driving cycles, despite the lack of complete drive cycle coverage for RCCI mode. During RCCI-only operation, fuel usage was found to be between 57 and 69% gasoline.
