Clean Car Technology by James R. Mondt J.R. Engineering, Ltd. Fort Collins, CO 80525 retired from General Motors Wednesday, February 14, 2001 3:30-4:30 p.m. Room 108 ME Broadcast on UNITE Channel A Coffee and cookies will be available in 152 ME following the seminar
During the 1960’s, undesirable air pollutants from automobiles were identified as unburned hydrocarbons, carbon monoxide, oxides of nitrogen, and photochemical ozone in smog. In response to US legislation, passenger cars began meeting emission standards in 1966 in California, and in 1968 in the rest of the United States. Emissions standards have been lowered in steps so that by the end of 2001, emissions from passenger cars will be lowered 99.3% for unburned hydrocarbons, 96.0% for carbon monoxide and 95.1% for oxides of nitrogen from the uncontrolled levels of the late 1960’s. Fuel economy has more than doubled. The 35-year evolution in technology to control emissions has included modified engine designs, spark timing and fuel metering; and novel additions of exhaust gas recirculation, catalytic converters, computer control, fuel injection systems and feedback controls. James R. Mondt received a B.S. degree in Mechanical Engineering from the University of Denver. His career began at the General Motors Research Laboratories in 1953 and focused on SI piston engine and gas turbine engine research. His career was interrupted by a military leave of absence from GM for two years (1954-1956, 1st Lt. Ordnance Corps). He earned a GM Fellowship to Stanford University, Graduated with an MSME, in Mechanical Engineering in 1957. He returned to GM Research where he worked in the areas of Thermodynamics, Heat Transfer, and Fluid Mechanics applied to research on advanced automotive power plants including gas turbine, free pistons, hybrids, steam, and advanced gasoline and diesel. In 1969, he was assigned to the original "GM Catalyst Team," (a joint project with AC Spark Plug Div). to develop a catalytic converter system to control emissions from spark-ignited piston engines. He transferred from GM Research to AC Rochester Division, in 1988, to develop the metal-monolith catalytic converter. In 1991, Mr. Mondt was appointed Staff Engineer and retired on August 1, 1996 from managing the Systems Technology and Consortia Management Group for Exhaust Subsystems Engineering. He served as Coordinator for USCAR LEP Cold Start Emissions Team and Lean NOx CRADA. Dr. Mondt has 15 patents, and has authored 20 publications. He is a recognized international authority on systems and hardware for controlling automobile exhaust emissions. He has lectured on emission controls systems in Brazil, Italy, England, Germany and India; and in the US at Stanford University, Michigan State University, and Rensselaer Polytechnic Institute. His textbook: "Cleaner Cars – The History and Technology of Emission Control Since the 1960’s," was published by SAE in January, 2000. He is a member of ASME (American Society of Mechanical Engineers), SAE International Society of Automotive Engineers), Combustion Institute, Michigan Catalysis Society, and Sigma Xi. He served on the ASME Gas Turbine Heat Transfer Committee, is currently a member of the ASME ad hoc Committee on Heat Transfer Education, and was chairman of a panel discussion in Atlanta in November, 1996. He is a member of the SAE Vehicular Heat Transfer Activity, Initiated the International SAE VTMS Conference, Vehicle Thermal Management Systems (joint effort between SAE and IMechE) and chaired the program committee for VTMS1 in 1993, Co-chair of Technical Committee for VTMS2, 1995, VTMS3, 1997, VTMS4, 1999, and VTMS5, 2001. Chairman of the SAE Transactions Selection Committee for all papers related to vehicular emissions.
