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. Their paper is published in the International Journal of Engine Research. RCCI background.

RCCI, a dual-fuel combustion technology developed by Dr. Rolf Reitz and colleagues, is a variant of Homogeneous Charge Compression Ignition (HCCI). The process involves introduction of a low reactivity fuel into the cylinder to create a well-mixed charge of low reactivity fuel, air and recirculated exhaust gases.

The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.

The research projects will contribute to the development of high efficiency internal combustion engines with the goals of improving fuel economies by 20-40% in light-duty vehicles and attaining 55% brake thermal efficiency in heavy-duty engine systems. Michigan State is partnering with Chrysler LLC for this effort.

Preliminary results from a new study by a team from Oak Ridge National Laboratory (ORNL) and the University of Wisconsin suggest that the fuel properties of moderate biofuel blends such as E20 and B20 increase the benefits of the use of Reactivity Controlled Compression Ignition (RCCI).

General Motors last week again highlighted the progress it is making with advanced HCCI (homogeneous charge compression ignition) gasoline engines by showcasing a demonstrator unit. Najt, then at the University of Wisconsin, and David Foster published the first study of a gasoline-fueled four-stroke HCCI engine in 1983.).
