Cars, a mode of transport used in all our daily lives. Over decades cars are evolving and being revolutionized by science to improve efficiency and safety. Efficiency defines how fast our cars move, how much fuel they waste per mile, how safe our cars keep us, how proficiently a car drives. To keep our cars productive there are many chemical reactions that occur to keep these factors perfect. The two that are primarily focused about in the essay are fuel combustion and airbags.
Every instance the car is in use there is a massive chance of a safety breach and injury. The airbag will instantly minimize the effect of the large force from the accident and protect the passengers. It halts the forward motion of the passenger in less than a fraction …show more content…
An example of an efficient car that has been successful due to scientific engineering is the Toyota Prius. The worlds top selling hybrid car with cumulative global sales of over 3 million units by June 2013. The Toyota Prius’ tailpipe emissions (grams per kilometer CO2) is 82g/km. While another popular car such as the Toyota Land Cruiser’s tailpipe emissions is 214 g/km. This shows how after scientific innovations a hybrid car, that is electric and fuel powered car, has evolved into one of the most popular and has 132g/km less than the Toyota Land Cruiser.
This proves how science has incorporated the fuel combustion reaction in the car and has evolved into making it more efficient and more popular than ever by minimizing the amount of pollutants it releases. Personally I believe that these innovations have bettered society as a whole as the science in these reactions has not only made automotive vehicles safer and quicker but more efficient in releasing pollutants as well. The cars of today have been altered by science to make a superior vehicle that will not only benefit us but also the future of the planet in a large

Vehicles are a main necessities of our life, it have been with us for quite a long period; it is time efficient, but the number of death it have caused is not easily avoided; therefore the engineers have designed vehicle safety features such as seat belts and crumple zones regarding the concepts of Newton’s Laws of Motion to help save our lives.
In order to first convince a wide majority of people that something needs to be done to stop the destruction of our environment, people first need to know exactly what is harmful about gasoline vehicles. In the United States, approximately 6.6 tons of greenhouse gases are emitted per person every year. Most of the greenhouse gas emi...
Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.
Nowadays, along with the development and increase of economical level, the automobile has become an essential and important transport. Also, it leads to another problem: traffic accident. Over the last century, there were more crashes in U.S than the number of the wars that Americans have been through. Therefore, people started to notice that they need the automobile safety to protect themselves. Over the last 100 years, the automobile safety has changed a lot to give out the best protection that we’re using today. Below are 3 major features: safety glass, air bag and seat belt.
Cars can cause many different impacts of the environment like pollution to using up our natural resources. Up until the nineteen twenties oil was used in a rather moderate amount, this however would drastically change in those short ten years. With a progressive number of cars finding...
As humans delve into the twenty-first century, scientific research continues at an exponentially increasing rate. While the work of researchers seems to affect people in positive ways, the common debate among the general population is whether or not there is a limit to how far scientists can take their research and impact the future of society. The changes that scientists induce upon society often escape foresight, such as diseases, dangerous paints, and other products that do not pass the test of time. One big issue that is fiercely debated is how to go about switching to alternative-fuel-source automobiles, given that the world’s supply of oil will run dry relatively soon. The electric car seems to be the best candidate as a replacement for the moment, but many people are still weary about completely discarding the trusty internal combustion engine for an invention barely as old as the people who will buy them. The electric fuel is promising, but it has not been around long enough to undergo the test of time needed for mass acceptance. Here the more direct question arises: is the electric car the solution to a more economically responsible car?
Automobiles play a major role in today's society. Almost every American owns at least one motorized transportation vehicle. Some say they make our lives better by reaching places faster than before. Others say they are a harmful to the environment. Have they made our society better or worse? They may be fast, but do we as humans want our environment to suffer because of time. Face it, cars pollute. And they release destructive chemicals into the air. Air pollution can threaten the health of many subjects in the environment including human beings.
Stenquist explains electric cars might get their energy from coal, wind, nuclear, and solar sources; in addition, these capabilities which improve the environment by reducing the detrimental sources. Stenquist (2012) asserts that electric cars can better reduce the global warming emissions from the gases, which result in a cleaner environment (p. 2). Furthermore, the author interviews several people to
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 majority of people, especially in America, cannot go about their daily lives without a car. Automobiles have instilled themselves in peoples’ lives and shown their usefulness since their debut in 1769. Since then, humans have redesigned and refined the automobile thousands of times, each time making the vehicle more efficient and economical than before. Now as the world approaches an ethical decision to dwarf all others, many people look toward automotives for yet another change. The emergence of the hypercar due to ecological turmoil exemplifies the change the world has demanded. Hypercars alter everything people know about automotives, modern ecology, and fuel efficiency. Not only do hypercars offer a solution to many ecological problems humans are faced with now, they also represent the only logical area for the automotive industry, and by some stretch American society, to expand.
In today’s society, cars and other transportation vehicles produce pollution, harming the environment as well as one’s health. Engines produce toxic substances such as nitrogen oxides and sulfur dioxide. However, the invention of the catalytic converter has helped reduce the pollution. Catalytic converters were first used due to the contractions on toxic emission regulations in the 1970s. The catalytic converter “turn the harmful chemicals in vehicle exhausts into harmless gases such as steam” (Woodford). These catalytic converters are essential to creating a less polluted atmosphere. An engine with and without a catalytic converter differs greatly and the reactions occurring are very significant in understanding the role of the converter;
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.
Cars are the ultimate symbol of independence and individualism. They offer more than freedom. No other man made creation but car fulfills a man’s ego. Technology has been the evidence of how cars have evolved for about more than a century now. From a first car packing a single cylinder 958cc, 0.75hp engine to today’s most powerful 8000cc W16, 1300bhp Veyron. We live in such an engineering savvy era where even an increase of few grams in a vehicle’s weight means going back to the drawing board to get unerring dynamic performance. And for these exuberant reasons, mechanical engineering was a mere choice rather than a chance for me.
