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. The researchers suggested that further design optimization might enable the use of a standard diesel fuel instead of n-heptane. Earlier post.)

In the low-temperature combustion concept called gasoline direct compression ignition, fuel is ignited by compression rather than by spark, similar to GDi homogeneous charge compression ignition (HCCI). The novel concept offers the potential for diesel-like efficiency while maintaining very low emissions.
