MTZ worldwide is always in pole position when it comes to engine development and technology. Packed with detailed reports from research and development for highly specialised engineers. MTZ worldwide is an essential reading for technology-oriented management in the automotive industry with a special focus on engine development. Expert authors from industry and technology report on research projects.
Cover Story – Electric Drives
Protean Electric has developed an inwheel drive system that integrates motor, power electronics, digital controls and friction brakes in a compact housing. It offers a higher
degree of design freedom for
manufacturers and can even be used to convert existing vehicles to a hybrid or fully electric drive.
Cover Story – Electric Drives
Hydrogen will play an essential role for the sustainable mobility of the future. Fuel cells complement pure battery-electric mobility in cases where heavy vehicles need to travel long distances. The attractiveness of
this sustainable form of propulsion is significantly depending on economic feasibility for a wide range of use cases. The key to this is to be found in the industrialization of components
and subsystems as parts of mobile fuel cell powertrains, which Schaeffler describes in this article.
In the Interview, Dr. Jin Hwan Jung, head of the e-Powertrain Center at Hyundai in Namyang, provides his views on trends and technology paths in the areas of electric drives and traction batteries.
Development – Injection Systems
The potential of standard Direct Injection systems with multiple injection capability is typically not exploited due to the complexity that is associated with the application process for internal combustion engines. Optimal injection strategies must be determined for wide ranges of operation points and conditions to guarantee emission robustness. With
the model-assisted injection control approach presented here, Hitachi Astemo eases the calibration process to simplify combustion engine application thus limiting development
The Hydrogen Pressure Control Unit from Hoerbiger simplifies the use of hydrogen as a green energy source in electric vehicles. This integrated injector-ejector module takes passive
recirculation to a new level by
reducing complexity, costs, weight, and space requirements in fuel cells and making it up to four times more efficient than before. In this way, the passive principle can meet the load requirements of mobile fuel cells significantly better.
In The Spotlight
Problems with supply chains have always existed, but they are becoming extremely aggravated because of the covid policies of some countries, wars in some regions, and shortages of basic materials and microchips. Because cooperation between all participants along the value chain is highly asymmetrical, a
turnaround is needed.
Acoustics – NVH
In this paper, the Fraunhofer Institute for Structural Durability and System Reliability LBF presents an integrated concept for the cover of the power
electronics of an electric powertrain. Vibroacoustic metamaterials can effectively reduce the structure-borne
sound propagation and airborne sound radiation in wide frequency ranges, so-called stop bands. Experimental investigations show that a reduction in structure-borne and airborne noise of up to 12 dB in the one-third octave bands between 315
and 1000 Hz can be achieved.
Research – Hybrid Drives
The electrification of vehicle
powertrains holds great potential for reducing emissions of both pollutants and greenhouse gases. As part of the FVV research project No. 1312, the combination of a partially homogeneous diesel engine combustion process and additional hybridization was investigated on a vehicle concept at the University of Stuttgart. The modified combustion process can benefit greatly from the increased on-board voltage of a hybrid powertrain.
For more than 10 years now we have been a proud partner of the MTZ magazine. We are looking forward to looking after this outstanding brand for decades to come.
Many of our readers are high-ranking personalities in the field of powertrain development and production. There is a reason why they recommend our magazine to others – because our content offers the greatest added value in the entire industry. See for yourself.
This is an exclusive opportunity to find out about the very latest trends in the global automotive industry free of charge. The editorial team has given you direct access to the five most popular articles and comment columns. Click on the magazine cover to open the PDF file.
MTZworldwide is the English digital edition of MTZ, which has been published for over 80 years. Always at the pulse of drive development, its appearance has changed dramatically in recent years. Today it is the international technical-scientific magazine for engineers in drive development with a special focus on the development of electrified and combustion engine drives with a pronounced focus on the electrification of 48-volt to high-voltage and fuel cell applications.
The spectrum ranges from innovative passenger car and commercial vehicle drives to components and large engines. Of course, classic topics such as friction minimization, turbocharging or charge cycle and the valvetrain still have a firm place in MTZworldwide. It is therefore a must read for technology-oriented management and promotes the global transfer of information between manufacturers, the supplier industry, service companies and research and development centers all over the world.
Deputy Editor in Chief
The scientific advisory board of MTZworldwide is made up of industry experts who work for leading companies and research institutions. By sharing ideas on a regular basis with the editorial team, the board members help to maintain the high quality of the magazine’s content. The board provides the editorial team with first-hand information about the latest development trends and offers advice and constructive criticism.
