A team at the Engine Research Center (ERC), University of Wisconsin-Madison has demonstrated the viability of reactivity-controlled compression ignition (RCCI) in a two-stroke engine. They found that the low-reactivity fuel fraction and the high-reactivity start-of-injection timing were independent combustion-control levers.
