Tecnical Note: Analysis of non-regulated vehicular Emissions by extractive FTIR spectrometry: tests on a hybrid car in Mexico City
Atmospheric Chemistry and Physics, 2006Co-Authors: F. Reyes, M. Grutter, A. Jazcilevich, R. González-oropezaAbstract:A methodology to acquire valuable information on the chemical composition and evolution of vehicular Emissions is presented. The analysis of the gases is performed by passing a constant fLow of a sample gas from the tail-pipe into a 10 L multi-pass cell. The absorption spectra within the cell are obtained using an FTIR spectrometer at 0.5 cm?1 resolution along a 13.1 m optical path. Additionally, the total fLow from the exhaust is continuously measured from a differential pressure sensor on a \textit{Pitot} tube installed at the exit of the exhaust. This configuration aims to obtain a good speciation capability by coadding spectra during 30 s and reporting the Emission (in g/km) of both criteria and non-regulated pollutants, such as CO2, CO, NO, SO2, NH3, HCHO and some NMHC, during predetermined driving cycles. The advantages and disadvantages of increasing the measurement frequency, as well as the effect of other parameters such as spectral resolution, cell volume and fLow rate, are discussed. To test and evaluate the proposed technique, experiments were performed on a dynamometer running FTP-75 and typical driving cycles for the Mexico City Metropolitan Area (MCMA) on a Toyota Prius hybrid Vehicle. This car is an example of recent marketed automotive technology dedicated to reduced Emissions, increasing the need for sensitive detection techniques. This study shows the potential of the proposed technique to measure and report in real time the Emissions of a large variety of pollutants, even from a super ultra-Low Emission Vehicle (SULEV). The Emissions of HC's, NOx, CO and CO2 obtained here were compared to experiments performed in other locations with the same model Vehicle. The proposed technique provides a tool for future studies comparing in detail the Emissions of Vehicles using alternative fuels and Emission control systems.

The Emissions of HC's, NOx, CO and CO2 obtained here are similar to experiments performed in other locations with the same Vehicle model. Some differences suggest that an inefficient combustion process and type of gasoline used in the MCMA may be partly responsible for Lower CO2 and higher CO and NO Emission factors. Also, a fast reduction of NO Emission to very Low values is observed after cold ignition, giving rise to moderate N2O and eventually NH3 Emissions. The proposed technique provides a tool for future studies comparing in detail the Emissions of different technologies using alternative fuels and Emission control systems.

Design and Development of the University of Wisconsin's Parallel Hybrid-Electric Sport Utility Vehicle
SAE Technical Paper Series, 2003Co-Authors: Jason M. Helgren, Julie G. Marshaus, Ethan K. Brodsky, Glenn R. BowerAbstract:The University of Wisconsin - Madison FutureTruck Team has designed and built a four-wheel drive, charge sustaining, parallel hybrid-electric sport utility Vehicle for entry into the FutureTruck 2002 competition. This is a two-year project with tiered goals; the base Vehicle for both years is a 2002 Ford Explorer. Wisconsin's FutureTruck, nicknamed the 'Moolander', weighs approximately 2050 kg. The Vehicle uses a high efficiency, 2.5 liter, turbo-charged, compression ignition common rail, direct-injection engine supplying approximately 100 kW of peak power and a AC induction motor that provides an additional 33 kW of peak power. This hybrid drivetrain is an attractive alternative to the large displacement V6 drivetrain, as it provides comparable performance with similar Emissions and drastically reduced fuel consumption. The PNGV Systems Analysis Toolkit (PSAT) model predicts a Federal Testing Procedure (FTP) combined driving cycle fuel economy of 16.74 km/L (39.4 mpg) with California Ultra Low Emission Vehicle (ULEV) Emissions levels. These goals will be met while maintaining the full passenger/cargo capacity, appearance, and towing capacity of 2495 kg.

2000Co-Authors: Julie G. Marshaus, Asha Ramnarine, Amanda Pertzborn, Troy Nergaard, Ethan K. Brodsky, Mike Gall, Jennifer A. Topinka, Glenn R. BowerAbstract:The University of Wisconsin – Madison FutureTruck Team has designed and built a four-wheel drive, charge sustaining, parallel hybrid-electric sport utility Vehicle for entry into the FutureTruck 2000 competition. The base Vehicle is a 2000 Chevrolet Suburban nicknamed the “Moollennium.” Weighing approximately 2495 kg, the Vehicle uses a high efficiency, 2.4 liter, turbo-charged, compression ignition direct-injection engine supplying approximately 99 kW of peak power, and a three phase AC induction motor that provides an additional 78 kW (peak) of power. This hybrid drivetrain is an attractive alternative to the large displacement V8 drivetrain, as it provides similar performance with Lower Emissions and fuel consumption. The ADVISOR model predicts a combined Federal Testing Procedure (FTP) cycle fuel economy of 10.6 km/L (25 mpg) and California Ultra Low Emission Vehicle (ULEV) Emissions levels. These goals will be met while maintaining the full passenger/cargo capacity, appearance, and towing capacity of 3175 kg.
