Professor Sunwoo Myoung-ho of the Department of Automotive Engineering is an expert in the field of internal combustion engines and serves as a director at ACE lab. His paper, “Simplified Decoupler-Based Multivariable Controller with a Gain Scheduling Strategy for the Exhaust Gas Recirculation and Variable Geometry Turbocharger Systems in Diesel Engines,” discusses a novel method of applying a new control strategy in order to reduce the emission of nitroxide in diesel engines.
One critical disadvantage of diesel engine is that after the combustion, nitroxide is produced along with carbon monoxide and hydrocarbon and other chemicals. Once nitroxide meets water, it becomes nitrite hydrate (H2NO3) which could cause asthma and other bronchial diseases. There are two solutions that could be suggested to reducing nitroxide. First, is to control the engine in an extremely precise method, and, second, is to use catalyst to reduce nitroxide.
One certain benefit that could arise from Sunwoo’s studies is that it makes diesel engines more of a “green car” in addition to being fuel efficient. As the production of nitroxide level gets significantly lower, it results in improvement of air pollution, less bronchial diseases for people and reduction of exhaust fume as well. Sunwoo has been researching on clean diesel, which focuses on making the diesel engines much cleaner and greener, for decades .
Another program that Sunwoo, along with Hyundai Motor Company, has been focusing on for the past five years is meeting the Euro 7 standards. Euro 7 is the regulation of exhaust gases which is expected to go into effective in 2019. The draft for meeting the regulations has been produced so far. Sunwoo is planning to produce the cleanest internal combustion engine possible.
Sunwoo has provided some valuable advice for Hanyang students: “Find what you like the most. This is the primary mission of college life. Make your career different from others. This is the most important mission of all. Finally, never give up and do your best.”
