Authors Abstract
Content
Engine maps consisting of three-dimensional contour plots of engine performance parameters such as bsfc in the engine speed - bmep plane give a large amount of information in a very concise manner. Such maps can be drawn for many more parameters of interest if a high speed data acquisition system, such as E-DACS (Engine Data Acquisition and Control System) which was developed in-house, is used to obtain the transient data of combustion chamber pressure. New maps of: pmax, (dp/dθ)max, etc. from the pressure-crank angle data; isfc, imep, pumping losses, etc. from the pressure-volume data; ignition delay, burn angle, maximum rate of burning, maximum burnt gas temperature, etc. after conducting heat release analysis using the pressure-crank angle data, can be generated. Such an enlarged view offered by these new sets of engine maps will definitely prove useful to engineers, giving them newer insights.
