“…In-cylinder pressure data provides extremely valuable information for engine control as it is an instantaneous and direct measure of engine performance and combustion process. This information allows several engine monitoring and control capabilities [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]. The reliability and cost of cylinder pressure sensors is the driver for using estimation techniques to indirectly obtain the cylinder pressure value.…”

“…The obtained information is implemented to improve the control and diagnostics of the combustion process in order to meet the stringent emission regulations and to improve vehicle reliability and drivability. An adequately accurate signal of cylinder pressure is the prerequisite condition for many promising engine closed-loop control systems [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16], such as:…”

The information provided by the in-cylinder pressure signal is of great importance for modern engine management systems. The obtained information is implemented to improve the control and diagnostics of the combustion process in order to meet the stringent emission regulations and to improve vehicle reliability and drivability. The work presented in this paper covers the experimental study and proposes a comprehensive and practical solution for the estimation of the in-cylinder pressure from the crankshaft speed fluctuation. Also, the paper emphasizes the feasibility and practicality aspects of the estimation techniques, for the real-time online application. In this study an engine dynamics model based estimation method is proposed. A discrete-time transformed form of a rigid-body crankshaft dynamics model is constructed based on the kinetic energy theorem, as the basis expression for total torque estimation. The major difficulties, including load torque estimation and separation of pressure profile from adjacent-firing cylinders, are addressed in this work and solutions to each problem are given respectively. The experimental results conducted on a multi-cylinder diesel engine have shown that the proposed method successfully estimate a more accurate cylinder pressure over a wider range of crankshaft angles.
