CRF Article Chosen by The Journal of Chemical Physics to Commemorate 80th Anniversary

A 2012 article by CRF researchers David Chandler (in Sandia’s Transportation Energy Center) and the late Kevin Strecker, “Dual-etalon frequency-comb cavity ringdown spectrometer,” was chosen by The Journal of Chemical Physics as one of 80 articles to highlight the 80 years of outstanding work published in the journal. A schematic of Chandler and Strecker’s [...]

Sandia Maps Multiple Paths to Cleaner, Low-Temp Diesels

Using new optical-diagnostic techniques, Sandia combustion researcher Mark Musculus and his colleagues identified the sources of key pollutants from LTC engines. Understanding how LTC works as a combustion technique may lead to broader use of cleaner diesel engines. (Photo by Dino Vournas) A few years ago, the automotive and engine industries presented researchers [...]

Optimizing Engines for Alternative Fuels

As shown in this cross-section of the Sandia DISI engine, the central location of the fuel injector (f) and the design of the piston bowl (b) help stratify the fuel near the spark plug (e). Also shown are the piston (a), the piston-bowl window (c), which allows a wide-angle view from below into the [...]

Measurements of Thermal Stratification in a Homogenous Charge Compression Ignition Engine

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 [...]
