Powertrain Department

Introduction to Powertrain Department

The automobile is one of the evolving industrial and economic fields in the world, which has been the locomotive of economies, sciences, and extensive technologies at various levels for about 130 years and continues to play this role well. The automobile is a symbol of the latest human knowledge and technological achievements and is undergoing fundamental transformations in the coming decade.

One of the most important of these transformations is in the field of powertrains, power transmission systems, and energy management in vehicles. Advances over the past fifty years revolving around internal combustion engines and their transmission systems have been remarkable. Today, the battle among competitors is over hundredths of improvements in fuel consumption, emissions reduction, controllability, better driving behavior, reliability, and lifespan. Today, internal combustion engines are equipped with a variety of advanced technologies including EMS, OBD, CVVT, VILM, VCR, TwinTC, VGT, WGT, VIS, and their various derivatives. However, the issue of combustion quality with various fuels including gasoline, diesel, natural gas, liquefied petroleum gas, biofuels, alcohols, and recently hydrogen and ammonia remains a very serious research topic regarding internal combustion engines themselves. Additionally, the electrification of various accessories is among the technological focuses in this field.

With the advancement of science and technology, in addition to the development of manual transmissions, automatic transmissions including AT, CVT, DCT, and DHT hybrid transmissions have attracted the attention of researchers and industrialists. Today, topics such as reducing noise caused by Pitting and Scuffing in gear design, reducing Rattling/Clattering, designing and optimizing dry, wet, and Dual Clutches, selecting suitable lubricants for different transmissions, and matching the engine and transmission are among the subjects of interest to researchers in the automotive industry.

Furthermore, the design and performance optimization of various engine auxiliary systems such as cooling assemblies, air intake systems, HVAC systems, exhaust systems with a focus on catalysts, mufflers, and various filters, as well as EGR, are on the research and technology development agenda of researchers.

Meanwhile, in recent years, due to environmental concerns and the energy crisis, the development of various modern powertrains (BEV, PHEV, HEV, FCEV, and VIPV) has been highly prioritized by policymakers, industrialists, and researchers in this field. In the Powertrain Department, topics such as heat transfer, design of various thermal management systems (such as systems based on phase change materials, heat pipes, etc.), energy management, and Life Cycle Assessment (LCA) in batteries, fuel cells, photovoltaic panels, electromotors and control boards, hydrogen storage tanks, and energy recovery systems are studied and researched.

Individuals interested in any of the fields of internal combustion engines, batteries, classic and hybrid power transmission systems (specifically from the perspective of thermal-fluids mechanics) can pursue their interests highly professionally through master's and doctoral theses and dissertations under the guidance of expert and distinguished professors, competing globally with top-tier scientists.

It is worth mentioning that those interested in the application of artificial intelligence and various machine learning methods can enter this discipline to challenge the application of these modern methods in current and new powertrain systems, introducing new and creative ideas to the world of science and technology.

The Powertrain Department of the School of Automotive Engineering, relying on the valuable experience and knowledge that has accumulated over the years among its excellent professors and graduates, and based on outstanding industrial connections with powertrain research centers across the country, welcomes researchers and students interested in automotive powertrains to solve serious practical and industrial problems and challenges in this field.
