... application of scientific and technological knowledge in a humanistic framework, allow addressing the problems of society and economy. Figure 1 presents a graphic display of the relationship between STS for the benefit of mankind 10,11 . Developing potable water supplies, methods of clean energy generation (including the exploitation of abundant natural shale gas), controlling environment quality and public health have been established today as central concerns for modern science and technology. ...

The main source of energy for the propulsion of automotive and trucks is still internal combustion piston engines. These are constantly improved in such a way as to achieve the lowest possible consumption of low-emission fuel. The results of the simulation of new technologies are confirmed in experimental stands, thus being the basis for the develo...
In recent years, the number of motor vehicles in circulation has increased in proportion to Brazil’s economic growth, resulting in an increase in emissions of toxic gases from combustion, such as nitrogen oxide, particulate matter, carbon dioxide and volatile organic compounds, among other polluting compounds. This type of pollution has its impacts...
Gasoline consumption is greater than fuel oil production in Indonesia. The situation has come to that of a fuel oil crisis. Prior research indicates that the exhaust gas emission of motorized vehicles using gasoline contains lead still as heavy metal. The problem with vehicles using fuel gas is that with the engine ignited and left idling detonatio...
An increasing number of motor vehicles are connected with negative environmental impacts in relation to their operation. Among the main negative effects are exhaust gas emissions production. The annual increase in passenger cars and emissions from them deteriorates air quality daily. Traffic junctions also have a negative impact on increasing emiss...
Ambitious long-term greenhouse gas (GHG) emission targets require decarbonisation of the transport sector. Where plentiful supplies of low carbon electricity are available for road transport, passenger cars with internal combustion engines need to be replaced by electric vehicles. However, despite its growing share of transport's CO 2 emissions, no...

In this study, performance and emission values were obtained under full load by using ethanol-gasoline blends as fuel at different rates in a spark-ignition engine, and exergy, exergoeconomic and environmental analyses were performed with these values. Exergy of fuel entering engine and lost exergies through cooling system, exhaust and radiation were calculated. CO, CO2, HC, and NOX emissions released from engine into environment were measured, and according to environmental analysis, cost of CO2 emission was calculated as 393.78 USD/year for E0 fuel and as 306.78 USD/year for E30 fuel at 2000 rpm. Ethanol-gasoline blends at different rates, environmental damage can be reduced by around 30% on an annual basis. Furthermore, with environmental analysis, lowest engine output power cost was found to be 29.77 USD/MJ in E0 fuel at 2000 rpm, while highest engine output power cost was found to be 120 USD/MJ in E30 fuel at 4500 rpm.
