One of the last carbureted production cars was the 1990 Subaru Justy. Since the late 1980s, production cars have switched to electronic fuel injection from the previously used carbureted systems. Although electronic fuel injection and carbureted fuel systems have many various components and work differently, they each play an important role within an engine and they are both ways to deliver fuel to the engine. Each one has their advantages over the other. Carburetors are simple and easy, while and fuel injection is complicated but more efficient. Fuel injection has come to be the modern fuel system that new cars use today, but there are still many people that prefer the carburetor. Even though some people favorprefer carburetors over fuel injection, fuel injection is more efficient and can deliver more power than carburetors-which makes it the, best method of fuel delivery.
Electronic Fuel Injection is controlled by the electronic control unit. The electronic control unit manages the fuel and air mixture, idle speed, ignition timing and valve timingThis control unit also utilizes sensors which measures components such as air pressure, engine temperature, throttle position and engine speed(7).The fuel is sent to the engine with a high pressure electric fuel pump at around 35 psi. (8) The fuel pump sends the fuel through a fuel filter and through the …show more content…
Fuel injection systems can adjust the ratios of fuel and air to the best burning mixture. The best burning mixture releases the least amount of emissions possible. Electronic fuel injection also atomizes the fuel better than carburetors and allows it to burn better. Carburetors do not use O2 sensors like fuel injection systems so they cannot tell how well the fuel is burning and cannot adjust the ratios and the engines often do not burn fuel completely and produce more emissions, making electronic fuel injection systems best for the environment.

...Caner Bektas Comm106 Fall2012 Automobiles with Less Carbon Dioxide Emission Every day millions of people drive their cars in order to go their jobs or schools or because of any other reason. Unquestionably, automobile makes our lives easier and that is the reason why automobile is considered as one of the most important inventions. However, as the automobiles make easier our lives they also damage the environment. The carbon dioxide emission is one of the major harmful effects caused by vehicles operated by conventional combustion engines. So it is obvious that there is still room for improvement and major thing that must be done is reducing harmful effects of carbon dioxide emission on environment. The most significant reason why carbon dioxide emission is high for conventional combustion engine is the dependence on oil for fuels used in that type of engine. Especially in the big cities which have large populations, harmful effects are more significant because in those cities there is a traffic jam which is caused by large number of cars. As the technology improves rapidly, researchers and scientists are focusing on finding a solution which is beneficial for car producers as well as environment. Most significant goal is replacement of automobiles used widely today with energy efficient vehicle which leads to reduction in carbon dioxide emission that causes urban air pollution, climate change and dependence on imported oil. The air pollution caused by different types...

Diabetes

...In America, the fact that fast food restaurants are located at every corner many people becomes obesity leading to huge risk factors. The various issues of unhealthy living lead to multiple life threatening diseases, such as diabetes. When people hear the news that they have been diagnosed with diabetes, it makes them feel frightened. In 2011, statistics show that in United States 25.8 million of children and adults has diabetes (American Diabetes Association, 2012).

Diabetes is a serious life-long illness caused by high level of glucose in the blood. This condition is when the body cannot produce insulin that is located in the pancreas. Insulin is a hormone that moderates the blood level. Diabetes affects the process of how the body uses blood sugar (Collazo-Clavell et all. 2009). Glucose is significant since it is “the main source of fuel” (Collazo-Clavell et all. 2009). There is no cure for diabetes but there are ways to lower the risks. Although diabetes is a disorder, it can also lead to other factors such as heart attack, kidney failure, or death. A person with diabetes has to maintain a healthy lifestyle including eating the right food, exercising, controlling their blood sugar level, and be optimistic.

Tata Nano

...Case Summary The Tata Nano is a city car manufactured by Tata Motors which is made and sold in India. The Nano is the cheapest car in the world today. Before it went on sale, a price of 1 lakh Rupee (US$1,600) was widely touted. Since its 2009 debut, the price has increased; while the Nano remains the lowest-cost four-wheeled passenger vehicle in India, it is significantly more expensive than a motorcycle, a popular means of cheap transport in the country. In early 2006, Tata Motors announced its intentions to revolutionize the automobile industry through a centralized manufacturing plant. This plant was conceived in order to manufacture the much awaited “1 lakh Rupee car”, the world’s cheapest car. The launch of the Nano would not only be a huge coup for Tata Motors, but would also put the Indian car manufacturing industry firmly on the global map. As a result, the proposed launch had received wide media coverage both in India and internationally. In late 2006, several Indian state governments had approached Tata about establishing the Nano plant in their respective states. The plant would generate revenues for the state and create much-needed jobs. The economic and social benefits of Tata’s industrialization would also be crucial for a developing country like India and largely benefit only the state selected for the plant. The four-door Nano is about 10 feet long and 5 feet wide, and powered by a 623cc two-cylinder engine at the back of the car. The car has 33 horsepower...

Volkswagen Emission Scandal

...Analysis of Volkswagen 4.1 SWOT Analysis 4.2 结论(黑体小二) 注释(黑体小二) 参考文献(黑体小二) 附录(黑体小二) 谢辞(黑体小二) Abstract Environmental protection is becoming more and more important throughout the world. So the automobile industry tries to develop vehicles with good and positive emission output. In my thesis paper I will write about the Volkswagen emission scandal which happened this year in September. The Volkswagen Group is one of the biggest automobile manufacturer in the world. However Volkswagen manipulated the emission output through so called defeat devices. Through this fraud Volkswagen lost trust and faith of customers, employees, suppliers, investors, buyers and many other groups. I will try to analyze and explain the reasons why Volkswagen came to this situation. Introduction Volkswagen Group is a German corporation. It manufactures passenger cars, commercial vehicles, motorcycles and engines. It was the largest automobile maker in the world in 2011. The company owns 12 brands, which are Audi, Volkswagen, Bentley, Porsche, Skoda, Lamborghini,...

The Aria is a very significant product for Tata Motors, not just for the Indian market, but for their key export markets in Europe as well. A closer look at the pictures of the Xover and the Cliffrider will tell you that the final lines and quite a bit of the exterior detailing of the Aria were frozen back then. However, it is good to see Tata Motors finally launch a seven-seater MPV – although the Aria is a lot more than just that thanks to all the four-wheel drive underpinnings and is a true crossover in every sense of the word.
