  • Can a gas engine use diesel fuel with less pollution?

    Anyone concerned with rising oil prices and pollution from fossil fuel might like to know about a new technology, which addresses both problems. Its application will put an end to the days of sooty smoke seen from accelerating diesel trucks and buses. The ...


  • Future of diesel engines with biodiesel economy

    Biofuel is a fuel from biological raw materials. Any animal or vegetable fat can become raw materials for production of the natural diesel practically. Biodiesel economy is really changed after technology was allowed to make fuel from algas, commercial crops, animal fats and even the fulfilled culinary oils can become the most widespread source of fats. This fuel is safe in production and use, it ...

  • Effects of nanoparticle-blended water?biodiesel emulsion fuel on working characteristics of a diesel engine

    An experimental investigation is carried out to establish the performance, emission and combustion characteristics of a diesel engine using jatropha biodiesel, jatropha biodiesel emulsion fuel (5% of water, 93% of biodiesel, 2% of surfactants) and alumina-nanoparticles-blended jatropha biodiesel emulsion fuels. The nanoparticles are mixed with the biodiesel emulsion fuel in the mass fractions of ...

  • Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland

    The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Air quality issues drive vehicle alternatives

    Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...

  • Ambient Air Quality in India - An Alarming Report

    Are we mortgage India against air pollution? The answer may be “Yes”. The reason is India has witnessed a phenomenal increase in the number of industries and vehicles in the last decade, along with the mushrooming of cities. As a consequence, there has been a dramatic deterioration in the quality of urban air in most regions of the country particularly in big cities like Delhi, Mumbai, Kolkatta ...


  • Fast Action to Reduce the Risks of Climate Change: U.S. Options to Limit Short-Lived Climate Pollutants

    Short-lived climate pollutants such as soot, methane and hydroflurorocarbons (HFCs) account for 30 to 40 percent of global warming to date. Targeted efforts to reduce these emissions can slow the pace of global warming and moderate climate impacts already underway, including the melting of sea ice and glaciers. By reducing local air pollution, such measures would also produce substantial public ...
