February 27th, 2013|Categories: CRF, Energy, Facilities, News, News & Events, Partnership, Research & Capabilities, Sensors & Optical Diagnostics, Transportation Energy|Tags: , , , , , , , , , |

Schematic of the optically accessible HCCI research engine. Homogenous charge compression ignition (HCCI) engines use fuel mixed with a substantial amount of excess air or recirculated exhaust gas that is compressed in the combustion chamber until it autoignites. The resulting combustion is a flameless and low-temperature burn that consumes less fuel than traditional spark-ignition internal combustion engines, and therefore, produces less carbon dioxide. HCCI engines have diesel-engine efficiency but without the accompanying nitrogen [...]
