Figure 15 shows the breakdown of projected fuel usage by application including off-highway usage U. Major phases in the reduction of automotive emissions. Some real-time monitoring techniques based on the absorption of light fail when applied to diesel exhaust analysis, either because of scattering of light by suspended particulates or absorption of light by aromatic HCs present in the gaseous phase. Projected motor fuel consumption by vehicle type. Carousel Previous Carousel Next. The impact of fuel switching on emissions depends upon its duration and certain vehicle characteristics, but emission increases of percent for HCs and percent for CO can easily occur Greco

    Aldehyde and unburned fuel emissions from methanol-fueled heavy-duty diesel enginesGeneral Motors Research PublicationJuly 15,Warren, Mich. The effects of artifact formation can be minimized by reducing the length of time a filter is exposed to the exhaust stream to the minimum required to collect a suitable sample, by using inert materials for filter construction, and by cooling and diluting the exhaust stream prior to sample collection.

    During the past 15 years, emissions have been significantly lowered by improved design of the engine and fuel system while still achieving the high fuel economy demanded by the federal standards and the consumer market.

    The control analyzes the input signal and calculates with in a split seconds the control signals required for the high pressure pumps, the nozzle and the other actuators.

    Emissions standards and test procedures in the United States have changed significantly since the first automobile emission standards were imposed in California in see table 1 General Motors Corp.

    Imposing the HC, CO, and NO x standards has resulted in 84, 79, and 56 percent reductions, respectively, in 50,mi emissions from gasoline-powered, sparkignition vehicles. Although the measured HC and CO concentrations are higher than the standards, the difference between the actual emissions and the standards appears to be narrowing although the ratio is not decreasing as improved technology, more frequent inspection and maintenance, and better training of mechanics has occurred.

    The MVMA study sampled 1, vehicles, allowing the following conclusions to be reached to a 95 percent confidence level by Survey Data Research :. Then, a specially designed oxidizing catalyst converter locating near the entrance of the particle filter unit will combust the remaining unburnt fuel come from the "postcombustion".
