    Article citation info: BUCZEK, K., LAUER, S. Firing order selection for a V20 commercial diesel engine with FEV Virtual Engine. Combustion Engines . 2017, 169 (2), 64-70. DOI: 10.19206/CE-2017-211 Konrad BUCZEK CE-2017-211 Sven LAUER Firing order selection for a V20 commercial diesel engine with FEV Virtual Engine The continuously increasing mechanical and thermal loads of modern engines require optimization of the designs with incorporation of a wide range of different aspects. Application of advanced computer simulations in the development process for most engine components is well established, leading to the creation of well optimized products. However, the optimization of such design variables like the firing order, which influences engine operation in several disciplines, is still challenging. Considering the ever increasing peak firing pressure requirements, the layout of the firing order in multi-cylinder commercial engines is an efficient way to reduce crank train / overall engine vibration and main bearing loads, whilst controlling engine balancing and preserving adequate gas exchange dynamics. The proposed general firing order selection process for four-stroke engines and, in particular, its first part being the optimization of the firing order based on crank train torsional vibration, is the main topic of this paper. The exemplary study for a V20 high speed commercial Diesel engine regarding the influence of the firing sequence on crank train torsional vibration has been conducted with the multibody dynamics simulation software “FEV Virtual Engine”. It addresses various engine crankshaft layouts and engine applications. Key words: firing order, torsional vibration, commercial engine powertrain 1. Introduction Subsequently, all alternative firing orders are to be gen- Selection of the firing order for typical automotive en- erated.

BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Cesare Palestini Title Engine crankshaft torsional vibration analysis for anomalies detection Degree programme Mechanical Engineering Major Master’s Programme in Mechanical Engineering Code of major ENG25 Supervisor Professor Petri Kuosmanen Advisors Dr Irene Gallici, Dr Juho Könnö Date 31.5.2018 Number of pages 61+4 Language English Abstract Reliability is a key factor in medium speed engines. Since they are employed in power plants and vessels, there is the constant need to increase the accuracy of their anomaly detection loops. Here I investigated a novel idea aimed at decreasing the number of sensors deployed. The goal was to understand whether using only one speed sensor, located at the flywheel, is enough to detect and possibly classify different abnormal operating conditions. A torsional vibration model of a V20 spark-ignited gas engine was developed and validated with field data. The model was then used to simulate normal, heavy knock, misfire and overpressure conditions. Subsequently, the speed signals ofthe crankshaft, measured at the flywheel, were analysed in the time- and frequency- domains, in order to identify possible patterns that could be linked to the four scenarios. The spectra of the signals were then processed with two machine-learning approaches: pattern recognition and a neural network.

Now we are very pleased to welcome you to the second Torsional Vibra- tion Symposium from May 17th to 19th, 2017. We are again looking forward to welcoming torsional vibration experts from all around the globe, and to hearing lectures on a wide array of topics. In 2014 this specific meeting for torsional vibration experts attracted 186 participants from more than 20 countries. At that time 36 papers were presented and we are glad that during this second Torsional Vibration Symposium even more participants will be able to listen to an extended number of the latest technologies and technical trends. Being responsible for the conference, we would like to thank all the authors for their contri- butions to the event and for their efforts to make the program so complete. The exchange of knowledge and information between torsional vibration experts from universities, research institutes, consulting companies, software- and measurement companies and from the industry are of major significance to all of us. However, the conference does not only aim at contributing to the technical and scientific progress in the field of torsional vibrations, but it also aims at improving the cooperation between people with the same interests.

  • A Study on the Effects of Sequential Turbocharged Diesel Engines
    ; A Study ON THE Effects OF Sequential TURBOCHARGED Diesel Engines Michael AleXANDER LOONSTIJN A Study on the Effects of Sequential Turbocharged Diesel Engines by Michael Alexander Loonstijn to obtain the degree of Master of Science - Mechanical Engineering at the Delft University of Technology, to be defended publicly on Tuesday July 12, 2016 at 14:00. Student number: 1334298 Project duration: December 1, 2015 – July 12, 2016 Thesis committee: Prof. Ir. J.J. Hopman, TU Delft, committee chair Rear-Admiral(ME)ret. Ir. K. Visser, TU Delft, supervisor Ir. M. de Boer, DSNS, supervisor Prof. Dr. Ir. S. Klein, TU Delft This thesis is confidential and cannot be made public until 12-July-2021. An electronic version of this thesis is available at http://repository.tudelft.nl/. Abstract Sequential turbocharging is a technique where multiple turbochargers are connected to an engine. These turbochargers are switched in sequentially. The manufacturers of engines with this system claim that the part-load and transient performance is better in comparison to engines with a single turbocharger. These claims and other effects in these engines are not well documented in scientific literature. The motivation for this research assignment is the application of the Pielstick PA6B V20 STC on board of the Indonesian navy SIGMA corvettes. The sequentially turbocharged engines have been selected for this design, based on the operating envelope of the engine. At low speed, the sequentially turbocharged engines are able to deliver more torque than a normal turbocharged Diesel engine. Based on the operating envelope, the sequentially turbocharged Diesel engine is able to deliver similar benefits that are normally present in gas turbine and electric motor propulsion systems; high torque at low speed.
