Bangladesh is a small developing country with a huge potentiality to improvement of transportation. In the present situation, Government of Bangladesh identified that the vehicular emission is the second largest contributor of environmental pollution after the brick field resulting vehicular emission as one of the major issue of Air Population. With increased economic activity and automobile population, reducing emission level is attaining paramount significance for safekeeping the environment. Present study was conducted to investigate different fuel injection system. Merits and demerits of each system were analyzed and it was found that common rail fuel injection system provides a unique combination of high power, better mileage, and low environmental pollutant emission with moderate cost. Data analyses shows that Common rail system are better from others fuel injection system. Study was conducted regarding effectiveness of fuel system along with the emission norms to maintain vehicular emission effectively.

A Review of Isobutanol as a Fuel for Internal Combustion Engines
Sebastian Verhelst
Isobutanol, one of the four isomers of butanol (C4H9OH), possesses some favorable properties that make it an attractive fuel for internal combustion engines. For instance, when compared to ethanol, isobutanol features a higher heating value and lower hygroscopicity (which prevents corrosion and enables it to be transported via pipelines). Moreover, its addition to gasoline does not distort the fuel blend’s vapor pressure to the same extent as ethanol does. All of this while having a high octane rating. Those advantages over ethanol suggest that isobutanol has the potential to be used as a gasoline oxygenate or even as a neat fuel. Furthermore, the advances made in biotechnology have enabled isobutanol to be produced from biomass more efficiently, allowing it to be used in compliance with existing renewable energy mandates. This article reviews some of the relevant literature dedicated to isobutanol as a motor fuel, covering its merits and drawbacks. Several studies on its combustion...

The increase of traffic flow in cities causes traffic congestion and accidents as well as air pollution. At this time, air pollutants arises from the automobile exhaust, power plants, boilers, industries etc. In order to provide a simple and practical method for measuring the exhaust emission, this project is based on the vehicle exhaust emission under a certain level of road capacity constraints. In this project, the Un Burned Hydrocarbons (UBHC), Nitrogen Monoxide (NO), Carbon Monoxide (CO) and Carbon Dioxide (CO2) are considered as the indexes of total exhaust emission from three wheeler vehicles, and the speed is used as an intermediate variable. To verify the rationality and practicality of the sample for Axum, the measurement results will be taken from on-board vehicle measurements of tailpipe emissions of three wheeler vehicle using Exhaust gas analyzer, the measured value will be shown on the computer’s screen with the help of SCADA software and then analysis will to be done. Lastly, by using the measured values, vehicle pollution monitoring action plan will to be developed for Axum city.

Vehicle Emissions and Urban Air Quality: 60 Years of Progress
Rachael Dolan
The past 60 years have seen large reductions in vehicle emissions of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HCs), sulfur dioxide (SO2), and lead (Pb). Advanced emission after-treatment technologies have been developed for gasoline and diesel vehicles to meet increasingly stringent regulations, yielding absolute emission reductions from the on-road fleet despite increased vehicle miles traveled. As a result of reduced emissions from vehicles and other sources, the air quality in cities across the U.S. and Europe has improved greatly. Turn-over of the on-road fleet, increasingly stringent emission regulations (such as Tier 3 in the U.S., LEV III in California, Euro 6 in Europe, and upcoming rules in these same regions), and the large-scale introduction of electric vehicles will lead to even lower vehicle emissions and further improvements in air quality. We review historical vehicle emissions and air quality trends and discuss the future ou...
