Darius Mehta Darius Mehta
Manager of the Diesel Technology
Southwest Research Institute (SwRI)

Darius Mehta is the Manager of the Diesel Technology section at Southwest Research Institute (SwRI). He leads a team of engineers in advanced Diesel engine research activities focused on reducing CO2 and criteria pollutant emissions from passenger cars, on-highway trucks, and off-highway equipment. Mr. Mehta has 13 years of experience in engine research. He has managed and executed programs to develop low engine-out NOx solutions for 1.6L to 15L Diesel engines using advanced boosting, EGR, VVA, & fuel system technologies. Most recently, he has developed new cold start strategies for passenger car diesel engines to comply with upcoming U.S. 2025 LEV-III emission regulations. He is also the technical manager for the Clean High Efficiency Diesel Engine (CHEDE-VI) consortium, which has demonstrated 48% brake thermal efficiency on an on-highway Diesel engine. Mr. Mehta's formal training is in thermal and fluid systems, with an emphasis on combustion. He holds a Bachelor degree in Mechanical Engineering from the University of Missouri at Columbia and a Master degree in Mechanical Engineering from the University of Texas at Austin.
