Abstract: 1. Introduction
Engine indicating includes the measurement of instantaneous in-cylinder pressure, the
determination of the top dead centre (TDC) and the measurement of the instantaneous
crank angle (c.a.). These measurements are fundamental for engine combustion diagnosis
and for indicated work calculation.
In engine combustion diagnosis, the apparent heat release rate and the combustion reaction
extent are the most useful quantities obtainable from engine indicating data. The apparent
heat release rate is calculated by computing the amount of fuel chemical energy release
necessary to obtain the experimentally observed pressure, while the combustion reaction
extent is evaluated through the released fraction of the total fuel chemical energy. Heat
release analysis is often complemented using optical techniques and its utilization as a
diagnostic tool covers a wide range of objectives, including the development of new
combustion systems, the analysis of alternative fuel burning, the validation of mathematical
models for engine simulation, the investigation of combustion chamber insulation effects
and the study of new injection strategies. [...]
