Book Description
Tailpipe emissions data from hybrid and conventional model year 2010 Toyota Camry vehicles were collected during real-world driving on a single, 32-mile route over a period of 18 months. Samples from the tailpipe were transferred into the vehicles and analyzed for gas-phase pollutants in real-time by an MKS MultiGas 2030 Analyzer, a commercially available Fourier Transform Infrared Spectrometer (FTIR). Additional measurements including vehicle and engine operating parameters, tailpipe flow rate, GPS location, road grade, ambient temperature, and relative humidity were collected simultaneously, second-by-second.

Book Description
This report presents estimates of full fuel-cycle emissions of greenhouse gases from using transportation fuels and electricity. The data cover emissions of carbon dioxide (CO2), methane, carbon monoxide, nitrous oxide, nitrogen oxides, and nonmethane organic compounds resulting from the end use of fuels, compression or liquefaction of gaseous transportation fuels, fuel distribution, fuel production, feedstock transport, feedstock recovery, manufacture of motor vehicles, maintenance of transportation systems, manufacture of materials used in major energy facilities, and changes in land use that result from using biomass-derived fuels. The results for electricity use are in grams of CO2-equivalent emissions per kilowatt-hour of electricity delivered to end users and cover generating plants powered by coal, oil, natural gas, methanol, biomass, and nuclear energy. The transportation analysis compares CO2-equivalent emissions, in grams per mile, from base-case gasoline and diesel fuel cycles with emissions from these alternative-fuel cycles: methanol from coal, natural gas, or wood; compressed or liquefied natural gas; synthetic natural gas from wood; ethanol from corn or wood; liquefied petroleum gas from oil or natural gas; hydrogen from nuclear or solar power; electricity from coal, uranium, oil, natural gas, biomass, o_" solar energy, used in battery-powered electric vehicles; and hydrogen and methanol used inJiuel-cell vehicles.

Book Description
Vehicle fuel efficiency and emissions regulations are driving a radical shift in the need for high efficiency powertrains along with control of criteria air pollutants and greenhouse gases. High efficiency powertrains including vehicle electrification, engine downsizing, and advanced combustion concepts all seek to accomplish these goals. Homogeneous charge compression ignition (HCCI) concepts have been proposed have not been able to demonstrate the controllability to operate over a sufficient engine speed and load range to make it practical for implementation in production vehicles. In-cylinder blending of gasoline and diesel to achieve reactivity controlled compression ignition (RCCI) has been shown to reduce NOX and PM emissions while maintaining or improving brake thermal efficiency as compared to conventional diesel combustion (CDC). The RCCI concept has an advantage over many advanced combustion strategies in that the fuel reactivity can be tailored to the engine speed and load allowing stable low-temperature combustion to be extended over more of the light-duty drive cycle load range. The potential for advanced combustion concepts such as RCCI to reduce drive cycle fuel economy and emissions is not clearly understood and is explored in this research by simulating the fuel economy and emissions for a multi-mode RCCI-enabled vehicle operating over a variety of U.S. drive cycles using experimental engine maps for multi-mode RCCI, CDC and a 2009 port-fuel injected (PFI) gasoline engine. Simulations are completed assuming a conventional mid-size passenger vehicle with an automatic transmission. RCCI fuel economy simulation results are compared to the same vehicle powered by a representative 2009 PFI gasoline engine over multiple drive cycles Engine-out drive cycle emissions are compared to CDC and observations regarding relative gasoline and diesel tank sizes needed for the various drive cycles are also summarized. The well-to-wheel energy and greenhouse gas emissions from these drive cycle simulations running carious amounts of biofuels are examined and compared to the state-of-the art in conventional, electric and hybrid powertrains.
