Direct measurement of key molecule will increase accuracy of combustion models

(Feb.5, '15) 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 fidelity of models used by engine manufacturers to create cleaner and more efficient cars and trucks.
