Introduction When someone mentions diesel, many people still have the image of a loud and obnoxious machine that is hard to start in the cold weather. This may have been true twenty to thirty years ago, but could not be further from the truth today! With all of the advancements in engine and emissions technology; diesel has become the new standard in fuel economy and power while still maintaining strict pollution standards as mandated by the EPA. As C.J. Baker explained here, “Diesel development has come a long way, but the public perception of diesel is lagging 25 years behind...but the bottom line is still the same. Modern diesels are quick, powerful, quiet, easy to start in the cold, and don't smoke.”(Baker 2). Therefore I have chosen modern diesel as my topic, to help shine some light on the misunderstood beast that we call diesel. Also I hope to inform the public, that there is alternative technologies to gasoline and hybrid gasoline-electric vehicles, that perform a multitude of times better, while not damaging the environment. Diesel Fundamentals The way a diesel engine operates is drastically different from gasoline, instead of a spark plug pulsing seventeen times a second to initiate the explosion of the fuel, diesel relies on compression to generate the heat required to ignite, and create the explosion of the fuel. Also because of this diesel engines need to be built much stronger to endure the high-compression ratios required to contain the explosion. According to Lucy Lazarony, diesel cars and trucks provide twenty to thirty percent better fuel economy than comparable gasoline models (para. 1). This is because down to a molecular state diesel has “eleven percent more energy per gallon”(Baker, para. 7).

  • Gasoline Dependence

    1876 Words  | 4 Pages

    For over 100 years, the automobile industry has relied on gasoline as its main source of fuel. Gasoline is a colorless, highly flammable substance used in internal combustion engines. It is a fossil fuel made from crude oil, a natural gas formed from the remains of ancient plants and animals (Webster‘s Dictionary). Gasoline has positively influenced our way of life by providing convenient, on demand transportation. It has created a global economy that moves people and goods faster and more easily than ever imagined (Povey 12). Although a seemingly perfect substance, it has unprecedented flaws. The tremendous political, environmental, and economic problems resultant from the excessive use of gasoline leads to the conclusion that the automobile industry should not continue to rely on this source of fuel.

    The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.

    With a gasoline-fueled vehicle, buying gas to operate your car is a never-ending process. With the high price change of gasoline and oil, operating a gasoline-fueled vehicle tends to be very costly. While there are some types of small gasoline vehicles that get much better gas mileage than larger vehicles, even the most powerful gasoline cars will normally desire a contribution every month. According to some experts the only way a mainstream market for green vehicles wills materlize is with a pronounced and prolonged rise in fuel prices. (Buss, 4)

  • Hybrid Vehicles and Their Effect on the Environment

    Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
