Particularly, it has been suggested that sound barriers, erected to reduce noise, may prove effective at decreasing pollutant concentrations.
The aeronautical industry faces the challenge of designing new engines with a better specific fuel consumption while decreasing pollutant emissions such as nitrogen oxide (NO).
Therefore, the fuel economy and the decreasing pollutant emissions emitted to the environment through use of LPG cannot be completely achieved at cold start of the engines.
In a context of decreasing pollutant emissions, the transport sector has to tackle improvements to the engine concept as well as fuel diversification.
The use of diesel engines resulted in numerous mechanized improvements for decreasing pollutant emissions as well as fuel usage [ 1].
Of all the city's water sources, the Croton watershed is the only one covered by an order from the federal government to build a filtration plant to decrease pollutants.
At the center of the transaction was an interest held by Enron Ventures, an affiliate of Enron, in a company known as Catalytica Energy Systems, which is involved in the business of developing technology to decrease pollutants from energy-generating machines like gas turbines.
All engines are direct injection, which increases power and mileage and can decrease pollutants.
The development of most energy conversion systems is focused on increased efficiency and decreased pollutant emissions.
So the poly-generation system has ability to increase the power plant efficiency and decrease pollutant emission.
