AIMING Diesels (Atomisation, Ignition and Mixing In New Generation DIESELS) was a research project to determine the operating conditions for optimum performance of diesel engines.
Innovative instrumentations were developed which, together with current state-of-the-art instrumentation, quantified atomisation, ignition and mixing in a diesel spray, in terms of crank-angle-averaged vapour concentration at ignition locations, correlated with spray characteristics and in-flame soot levels for a range of injection schedule, injection pressure, TDC temperature and pressure, and Exhaust Gas Recirculation (EGR) conditions, corresponding to extreme emission conditions for NOx and particulates as determined from engine data. A phenomenological model will result for AIM for supercritical conditions, which will assist in providing suggestions for improved computational models and determining the operating conditions for optimum performance of engines.
