I. Introduction Taxi services and Firms are important for me because this is one of the most needed or most wanted commuting transportation in the Philippines, Its safer and more relaxing. Even when you going home late at night in Metro Manila, tired from work or not sober anymore from partying. And when you have a flight to catch in the airport. When you go shopping and just couldn't carry all the shopping bags going home around Metro Manila. Or tomorrow's going to be number coding day and you need a car service. These are the reasons for using taxi.
I am studying on what are the advantages and disadvantages of using LPG on cars, in taxi cars to be specific. This is for the conservation of money and environmental effects. After this study I will be able to share knowledge to others and for me since I am planning to have a taxi firm when I got the chance to. Also when I already have a car, for me to be able to know what will i do for me to spend less money for this liability.
II. Background of the Study Taxi transportation experts since 1993, they are known for a high standard of transportation, unmatched by our competitors. their reliable taxi sedan service goes far beyond the norm. They don’t only get you where you need to be, but we transport you with a level of care that can only be achieved through years of experience serving in metro Manila. Their taxi operators are local experts who know the best routes to get you to your destination on time. They are filling their tanks with diesel.
There are a lot of diesel station anywhere. Undergoing extensive background checks and regular training to keep up with the latest best practices. No matter where you need to go, 365 days per year, at any time of day, their experienced taxi operators are on standby.
III. Rationale of the study Filling one’s tank with diesel does not require a different technique, and there are diesel fueling stations in all 50 states. In metro manila especially, many gas stations also offer diesel fuel. However, engines that run on diesel fuel differ in their mechanics, which means that typical cars cannot be switched to use diesel without changing the engine entirely. Gasoline engines have a low compression ratio, which describes how much a combustion engine can be compressed, and is a measure of the amount of mechanical energy that can be extracted from the engine through combustion.
In contrast, diesel engines ignite by compression alone using fuel injectors, which make them use the fuel more efficiently. Cars that run on diesel include the BMW 335d sedan, the Mercedes R350, the Volkswagen Jetta, and the Volkswagen Golf, all of which have gas mileages from 18 to 30 miles per gallon in the city, and 24 to 42 miles per gallon on the highway. Most larger vehicles also use diesel, including some Ford models. The benefits of using diesel fuel include higher fuel economy and lower costs generally.
According to a study recently conducted by Carnegie Mellon’s Tepper School of Business, diesel cars are generally a better value than gasoline cars. Cars that use diesel fuel have higher residual value, which is an estimate of an object’s future worth. In some cases, the researchers observed residual values up to 30 percent higher for diesel, which indicates much lower depreciation. Diesel cars’ higher fuel economy also leads to lower vehicle operating costs. Since diesel fuel is more efficient (due to its higher density), each trip will require less fuel and will reduce money spent on fuel. Finally, the study, headed by economics professor Lester Lave, found that any disparity in initial vehicle costs was recovered within two years.
The disadvantages of using diesel fuel relate to environmental impact. Engines that run on diesel tend to emit more particulates like soot and nitrogen oxides, which contribute to smog formation. According to the U.S. Environmental Protection Agency (EPA), because diesel has a higher carbon content, it also emits more carbon dioxide per gallon of fuel consumed when compared to gasoline. However, the higher fuel economy of diesel reduces the amount of greenhouse gas emissions over the car’s lifetime.
There are also certain fuel additives, such as smoke suppressants and detergent additives, that have been developed to decrease the effect of diesel fuel on the environment. Smoke suppressants are organic compounds that reduce the amount of soot emitted by diesel engines, but conversely also increase the number of ultra-fine particles released into the atmosphere, as well as overall sulfate emissions. Detergent additives are used to keep engines cleaner by removing oil deposits on fuel injectors, which also increases efficiency of the engine.
