Download or read book Estimation of Cylinder Wise Combustion Features with Combined Processing of Engine Speed and Cylinder Pressure Regarding Torsional Deflections of the Crankshaft written by Christoph Kallenberger and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising fuel prices, stricter emission standards, as well as the increasing demands from consumers for driving comfort, all motivate the rapid development and improvement of combustion engine control systems. New concepts, such as variable valve timing systems, downsizing in combination with supercharging systems and new injection systems bring significant advantages for engines, however they result in increased system complexity. In order to provide optimal operating conditions for these concepts, advanced control and diagnosis strategies are necessary. They require feedback information from the combustion chamber. The in-cylinder pressure has a close relationship to the thermodynamics of a combustion and, consequently, is suited to this purpose. In-cylinder pressure sensors are already widely used in today's research engine test beds. However, a fully-equipped engine with pressure sensors is too expensive for series production. This motivates this work to investigate a cost efficient approach using only one in-cylinder pressure sensor in combination with the engine speed sensor. The engine speed signal contains the cylinder-wise combustion information and is measured at the crankshaft. Torsional defections at the crankshaft distort the engine speed signal. This work shows how to compensate this effect in order to provide highly accurate combustion features for engine control and diagnosis.

Download or read book Determination of Diesel Engine Cylinder Gas Torques from Speed Fluctuations with A High Fidelity Crankshaft Torsional Model written by William J. Swanson and published by . This book was released on 1998-12-01 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to develop a method of predicting cylinder indicated torques in a reciprocating engine by measurement of crankshaft angular velocity fluctuations. Cylinder indicated pressures were measured for all three cylinders of a two-stroke Diesel engine with pressure transducers. Time-resolved angular position was measured at the crankshaft front and at the flywheel. A six degree-of-freedom torsional crankshaft model was developed. Two solution methods are described to solve the equations of motion: a time-marching ODE solver, and a Finite Element solution in the time domain. Using these methods with the measured cylinder torques, the angular positions are predicted and compared to measured angular positions for model calibration. An inverse solution method was developed to determine the cylinder indicated torques from the measured angular position at the crankshaft endpoints. The method is theoretically demostrated to be useful for explicit solutions for two-stroke engines up to three cylinders, and four-stroke engines up to four cylinders. Experimental results show that the method is useful in predicting cylinder indicated torques from angular velocity measurements.
