Event: FISITA World Congress 14-16 September 2021 online
Name: Ondrej Bolehovský, Junior Researcher
Company: Faculty of Mechanical Engineering, Czech Technical University
Presentation Title: F2020-ADM-063 Development of Advanced Engine Brake for Heavy-Duty Vehicles
Please introduce yourself briefly…
I graduated from the Czech Technical University Prague in 2010 in the field of internal combustion engine. Since that time, I have dedicated my professional career to thermodynamic simulations of combustion engines with the focus on gas exchange processes (advanced valve actuation) and boosting systems. I have spent 8 years as a researcher at the research center of the Czech Technical University in Prague and in 2020 I moved my career further by joining commercial vehicle team in Eaton based in Eaton European Innovation Center near Prague.
What you will talk about at this year’s FISITA World Congress?
My contribution to the FISITA World Congress 2021 is related to the recent research in the field of advanced engine brake systems for heavy duty vehicles. The paper summarizes the process from the valve lift profile optimization (thermodynamic simulation) up to the engine dynamometer testing. It is an interesting and uncommon topic in the internal combustion engine research.
What benefits will participants gain from your presentation?
The paper itself offers an interesting insight into the engine brake system principle and design. Presented advanced engine brake system utilizing 2-stroke cycle attains braking power that is higher than the positive rated engine power. Such braking performance is enabled solely by advanced valve actuation (very low added mass) and provides high braking power even at low engine speed.
heavy duty vehicles go the way of combustion engine efficiency improvement
Which trends do you consider as the most important for your domain of research and your geographical region?
The trends in the combustion engine research are quite clear these days: Strict emission limits are pushing the manufacturers to maximize combustion engine efficiency or to partly replace its operation by electric motors with zero local emissions. The heavy duty vehicles go rather the way of combustion engine efficiency improvement, which paves the way for advanced technologies and systems and thus represents both opportunities and challenges.

About the FISITA World Congress
Since 1947, the FISITA World Congress has been the leading international meeting place for industry experts, engineers and executives to exchange ideas and discuss the trends that drive the automotive industry forward. The theme for the 38th FISITA World Congress is 'From automobile to mobility. New roles. New challenges' and it will take place 14-16 September 2021, with the opportunity for the global audience to join virtually available for the first time. Registration is now open, with the Early Bird and special registration rates available until 31 August 2021.
Content from the 2020 FISITA Web Congress is available within the FISITA Technical Library, while material from previous Congress events back to 1998 is available in the FISITA Store. By the time of this year’s Congress, all the content will be available within the FISITA Technical Library, with free access provided to FISITA members.
