Sandia explores aggressive high-efficiency sparkplug-free gasoline auto engines

LIVERMORE, Calif. — Researchers at Sandia National Laboratories’ Combustion Research Facility are helping to develop sparkplug-free engines that will help meet ambitious automotive fuel economy targets of 54.5 miles per gallon by 2025. They are working on low-temperature gasoline combustion (LTGC) operating strategies for affordable, high-efficiency engines that will meet stringent air-quality standards. Sandia researchers […]

Direct measurement of key molecule will increase accuracy of combustion models

LIVERMORE, Calif. — Sandia National Laboratories researchers are the first to directly measure hydroperoxyalkyl radicals — a class of reactive molecules denoted as “QOOH” — that are key in the chain of reactions that controls the early stages of combustion. This breakthrough has generated data on QOOH reaction rates and outcomes that will improve the […]
