A Brief Note On Porsche 's Engine Downsizing

The goal of the new engine was to provide customers with an engine that had a higher torque output, more horsepower and could comply with the new federal emission

All combustion engines release pollutants that damage the atmosphere like carbon dioxide and other gases. Nora states that Diesel engines emit black carbon which is worse than any other version of carbon dioxide. That black carbon can really harm the health of people because when it is deeply inhaled it can trigger asthma attacks and exacerbate chronic bronchitis. The international agency for cancer research has labeled the particles of black carbon carcinogenic. This explains how diesel exhausts are harmful to the environment and the people and animals that live in it. This proves that the diesel engines are not the way of the future unless they find a way to clean up the emissions that diesel engines

The number one reason why electric cars became popular is the ability to reduce the air pollution. According to the U.S. Environmental Protection Agency (EPA) almost 30% of greenhouse gas emissions are caused by transportation and most of them could be reduced by driving electric cars. The UK Department for Transport divides vehicle emissions in two categories: direct and life cycle. Direct emission are created by burning fuels while driving on the road. Petrol, diesel, and other alternative-fuel engines produce very high amounts of gases, that not only have impact on our health, but also on climate change. Gases like NO or CO2, that are known for causing many different respiratory illness. There is an estimate of 29,000 deaths a

The U.S government has been actively involved in overseeing emission standards for years. This corresponds with the statement made by the U.S Department of transportation that, “Transportation is the largest end-use sector emitting CO2”, and also the statement released by the NRCAN in which, “Fuel usage & carbon dioxide emissions have grown steadily over the past two decades.” These factors are only to be associated with your average four door sedan and/or light truck. These do not include your 18 wheelers, heavy trucks, or the gas guzzling vans that emit more carbon dioxide into the air and are also on the road more today than ever have been before. Cars are readily and easily obtainable more so now than ever have been. This creates more fuel to be burned up in which produces more toxins to be constantly released into the atmosphere. In fact, according to Scientific American “cars relate as much as 30 gallons of GHG, while only driving 3 miles.” These miles can be correlated with something just as simple as your average work commute. According to the United States Census Bureau, “Nearly 600,000 full-time workers had "megacommutes" of at least 90 minutes and 50 miles.” Those workers alone would each be releasing up to 500 gallons of GHG. These can be considered some of the bigger factors that the greenhouse gasses have taken a toll on.

The second largest source of greenhouse gas emissions in the United States is related to transportation, the burning of oil to produce energy in a combustion motor. The combustion process inside of engines is what produces the carbon matter that is emitted into the air through the exhaust system on gas-powered vehicles. Gas-powered transportation is accountable for 24 percent of the global carbon emissions; this should not come as much of a surprise given the amount of urban sprawl that is being seen in the United States and across the globe. In the past decade, the Environmental Protection Agency, the United States government, and major car manufacturers have been working in conjunction to find ways to provide a “greener” form of transportation (EPA, 2011). This has included testing the use of hydropower, ethanol, natural gas, biodiesel, and electricity as a means of powering vehicles, which has led to the introduction of hybrid vehicles. Hybrid vehicles run on electricity and gasoline, the byproduct of oil that is generally used in the engine combustion process of vehicles (U.S. Department of

First, cars pollute the environment. In 2012 the EPA reported that a whopping 28% of emissions came from transportation. As it says in the article “Running off the Road”, by Grover Kingsley, “With their largely petroleum based fuel, cars constantly spew carbon monoxide into the air.” We are responsible for the

Chapter 6, “The Burden of History: Expectations Past and Imperfect” from Kirsch’s book, The Electric Vehicle and the Burden of History, focuses on the problem of automobiles in the modern day. Kirsch states that internal combustion engines release greenhouse gasses, which harm the environment. Each individual contributes to air pollution

Motor vehicles are a leading source of air pollution. Even though automobile and truck engines have become far cleaner in recent decades, the sheer

Every day, millions of Americans turn on the engines of their cars and drive to school or work. What these people do not realize is that the vehicles they operate greatly pollute the planet. According to the Environmental Protection Agency’s recent website post, “Environmental Impacts from Automobiles”,

With the supply of fossil fuels steadily declining, gas and oil is becoming harder to harvest which means it is getting more expensive. Fossil fuels take millions of years to be naturally produced, yet each person burns gallons of gas per day (Maehlum par. 5). Though fossil fuels are produced naturally, when burned they release nitrogen oxides gases into the atmosphere, which contributes to the formation of smog and acid rain. According to the EPA, major sources of these nitrogen oxide emissions come from cars and trucks, coal-fire powered plants, large industrial operations, and ships and airplanes (EPA par 3). By reducing the number of gas powered cars on the road, we can reduce the amount of harmful chemicals we are releasing into our atmosphere.

Cars and truck account for 20% of all U.S. global warming emissions, where more than 24 pounds per gallon of carbon dioxide and other global warming gases come right out of the car’s tailpipe (“Union of Concerned scientists”). This frightening statistic is part of the reason why the federal government has put in place many policies and incentives such as the Clean Air Act, The National Program for greenhouse gas emissions, Catalytic Converter Federal Laws, and incentives of $12,000 in California to get people to upgrade to more fuel-efficient cars. With such programs and incentives put in places, it is also important that car companies such as Toyota and Ford also take action to further cut pollution rates. They have done so by

Climate change and transportation play a big role and it is important to be concerned for our future generations. The use of gasoline cars is a major producer in carbon dioxide emissions, although they are not entirely responsible for it—they play a role in it. Other form of transportations like buses and taxis also contribute to carbon dioxide emissions. The total amount of carbon dioxide emissions from an average car is seventy six percent which comes from usage of a vehicle containing gasoline. Efficiency has increased by twenty percent in regards to electric motors, especially when it comes to their wheels using no power when the car is at rest. Car ownership will increase and with this, improvements in technology could be a vital

While new trucks and cars emit about 90 percent fewer pollutants than they did 30 years ago total annual vehicle miles driven have increased by more than 140 percent since 1970 and are expected to increase another 25 percent by 2010. The emission reductions from individual vehicles have not adequately kept pace with the increase in miles driven. As a result cars and trucks are still the largest single

The author starts with the Gas-Engine; this is where we started, the foundation for how far technology has come. According to the article gas engine vehicles are one of the major leading causes of pollution which contributes to global warming. The gas engine

Automobiles are a major producer of greenhouse gas. One gallon of fuel burned puts five pounds of carbon dioxide into the atmosphere. Let’s say that an average car gets 25 miles to the gallon, and that car has a ten gallon tank. Every time a car gets filled up with gas, another fifty pounds of carbon dioxide have been put back into the atmosphere, and that is just one car. The automobile industry is very important to the world economy, so I am not saying that we should stop making cars, but there are other solutions. The recent trend of hybrid electric cars that get up to fifty miles to the gallon are becoming more popular. Also public transportation is very important. City dwellers that live downtown, do not need to drive their cars to work. Every major city has a form of public transportation that can get anyone around the city, and for that gallon of gas a bus burns the same five pounds reaches the atmosphere, but instead of one
