modify its existing NZ-type engines by reducing the time for the ‘valve closing’ and making changes to the piston in order to alter the compression ratio . Since the ultimate aim of the new system architecture was to improve the fuel efficiency and thus decrease the carbon foot print, detailed attention was given even to the minutest of the sub- system, for example improved piston rings were used to decrease the friction to achieve better efficiency. Understanding that the battery may not…
The software activated full emissions controls during testing but reduces the effectiveness during regular driving. As a result, the cars emit nitrogen oxides at up to 40 times more than the allowable standard. The software enables cars to get better fuel economy at the cost of higher nitrogen oxide emissions (Boston et al., 2015). Volkswagen tried to sell their cars saying their cars had better performance and lower emissions but they did not mention the nitrogen emissions…
Metin GUMUS et al.,[1]. In this study, hazelnut (Corylus avellana L.) kernel oil was tested and studied as an alternative fuel in diesel engines. The hazelnut kernel oil is made to undergo transesterfication process for reducing the viscosity of the oil. The processed hazelnut kernel oil possesses all the properties of biodiesel used in the diesel engine. The suitable transesterification reaction conditions for hazelnut kernel oil are volumetric ratio of the reactants in the ratio 1:5, reaction…
In 2014, the US alone used 98.324 quadrillion BTUs of energy. Roughly 82% of that was fossil fuels. Renewable resources accounted for 10%, including solar, wind, hydroelectric, and more, and the remaining 8% was nuclear power. This energy was used to do everything from power our televisions to turn on our lightbulbs. Unfortunately, our reliance on fossil fuels brings with it serious side effects, including global warming. Because of these issues, a variety of alternative energy sources has been…
environmental standards on a state and federal level. Being that infants and young children are the most vulnerable population to air pollutants, taking these impacts into consideration would help to greatly strengthen air quality controls. To achieve air clean enough to only have little to no effects on pregnancy, infants health would require dramatic changes to transportation systems, motor vehicle and industrial processes. Until policies are put in place to achieve better air quality…
252 million years ago. The event is known as the Permian-Triassic Extinction Event or the “Great Dying” that killed around 90 per cent of all species on Earth. This event was caused by a series of volcanic eruptions that released great amounts of Carbon Dioxide (CO2) and other greenhouse into the atmosphere triggering a rapid global warming and climate change. Nowadays, scientists predict that we are…
masks? Many people in China will answer “No.” Rapid industrial development of China has improved people’s standard of living. However, it also brings some unwanted side effects, such as air pollution and water pollution. In order to develop industries, the consumption of fossil fuels increases. Burning of fossil fuels emits lots of air pollutants, such as sulfur dioxide, nitrogen dioxide, carbon dioxide, and other particles. Private cars and other vehicles also discharge a large amount of air…
The Central Valley has played an important role in California being the strongest economic state in the country. The Central Valley, which population centers comprise of Fresno, Clovis, Modesto, and Visalia, have contributed substantially to California’s economy by being one of its leading agricultural producers. In contrast to its city-orientated “brother” in south California, or the “Bay area,” the Central Valley does not typically have busy streets, tall buildings, sandy beaches, and…
that humans are by no means going to run out of this large electricity aid even for millions of years. That is not something we possibly can say for oil, coal, petroleum, and different fossil fuels that humans have been dependent on for thousands of years. If people need to save the earth from raising carbon-emission gases, pollutants of water, and even global warming, they ought to change the electricity sources they use at present. Seeking more alternative power resources can preserve the…
