In recent years, combustion community has been very interested in g-valerolactone (GVL). GVL can be derived from lignocellulosic biomass and possesses some of the important characteristics of renewable energy resources. We investigated the octane boosting effects of GVL as an additive to FACE (Fuels for Advanced Combustion Engines) J, a low octane gasoline surrogate, by employing Ignition Quality Tester (IQT) and Cooperative Fuel Research (CFR) engine. In this study, we used blends of 0-20% GVL and half of GVL fraction of ethanol by volume in FACE J. Ethanol was added to enhance the miscibility of the mixtures. The use of GVL looked promising in terms of octane enhancement in addition to the known properties of GVL for reducing harmful emissions during combustion of hydrocarbon fuels. GVL is nearly as effective as ethanol as octane booster, but GVL is more attractive due to its lower vapor pressure and also due to its propensity of reducing green-house gases emissions.
