Characterization of Particle Emissions from a DGEN 380 Small Turbofan Fueled with ATJ Blends

The fine particulate matter (PM) emitted from jet aircraft poses a serious threat to the environment and human health which can be mitigated by using biofuels. This paper aims quantify PM emissions small turbofan fueled with alcohol (ATJ) synthetic kerosene its various blends (5%, 20%, 30% of ATJ) Jet A-1 fuel. Emissions engine (DGEN 380) high bypass ratio, applicable in private jets, were studied. Among four fuels tested, PM-number emission index (EIN) was lowest for ATJ blend. EIN dropped 1.1 × 1017 4.7 1016 particles/kg Burning alternative fuel reduced particle mass over entire range flow at least 117 mg/kg particles formed nucleation mechanism dominate emission, is characteristic engines. Thus, number-based size distributions (PSDs) exhibit single mode log-normal distribution. highest values found neat compared other fuels. use additive did not cause significant changes mode. However, magnitude reduction increase ratio.
