One high-efficiency combustion concept under investigation is gasoline compression ignition (GCI)—the use of gasoline-like fuels to deliver very low NO x and PM emissions as well as high efficiency in a diesel compression ignition engine. For the study, the team used a single-cylinder engine based on a four-cylinder production GM 1.9L
