Combustion and emission characteristics of a compression ignition engine burning a wide range of conventional hydrocarbon and alternative fuels

General aviation aircraft driven by piston engines (APE) have gained a broad range of applications. Aviation fuels blended with long-chain alcohols is promising means for APE to mitigate its dependency on fossil fuel. Herein, the combustion and emission characteristics an compression ignition engine burning baseline diesel, RP-3 kerosene, synthetic Fischer-Tropsch (FT) fuel were analyzed. The tests carried out under different conditions via varying pentanol additive ratio (PAR), injection timing load variables. Response Surface Method (RSM) was utilized quantify effectiveness independent variables target responses indicated thermal efficiency (ITE), nitrogen oxides (NOx) particulate matter (PM) emissions. Compared pentanol-FT blends (40% PAR) significantly reduces NOx 81% PM 75% prominent increase ITE 7.2%. Based analysis variance, RSM-derived model demonstrated that type predominantly determines NOx, while PAR primarily alters binary effects further resolved quantitatively. Moreover, RSM well validated implement effective prediction performance/emission characteristics.
