Abstract
An experimental study was conducted to evaluate the use of JP-8 aviation fiiel as a full substitute for diesel fuel, in a Fetter AV1-LAB, naturally aspirated, fourstroke experimental diesel engine with indirect injection. The study covers a range of engine load at constant speed operating conditions, comprising measurements of cylinder pressure diagrams, fuel consumption, smoke and exhaust gas emissions (nitrogen oxides, unbumed hydrocarbons and carbon monoxide). Processing of the measurements provides important performance parameters such as maximum combustion pressure, knocking tendency and ignition delay. The differences in the measured performance and exhaust emissions parameters are determined for the JP-8 fuel engine operation, against the engine baseline operation when using diesel fuel. The study shows that no significant differences are observed on the basic operating parameters and the overall performance of the engine. When the engine is operating with JP-8 fuel, there is a considerable reduction of the emitted particulates but the other exhaust emissions levels are not very different for both modes (fuels) of operation. On the contrary, operation with JP-8 fuel increases combustion pressures, combustion intensity and irregularity.
