by the coolant system within acceptable service temperatures. With approximately 98% of the energy contained within the fuel being released on combustion in diesel engines, the combustion efficiency of a modern ICE is well optimised and 95–98% in gasoline engines(Roberts, Brooks, & Shipway, 2014). 1.1.1 Type of Engine Cycle In the basic principle of internal combustion engine, the internal combustion engine can be divided into many different ways whether types of ignition or engine cycle. i. Types

Ethanol is a renewable, domestically produced alcohol fuel made from plant material, such as corn, sugar cane, or grasses (USDOE, 2016). The use of ethanol is important because it can help reduce oil dependence and CO2 emissions. About 20% more emissions are formed when fossil fuels are refined to produce gas (Boyle et al., 2012). Therefore, any reduction in the need for refinement of fossil fuel will result in a decrease in greenhouse gas emission. Ethanol fuel use in the U.S. has increased dramatically

dollars on fuel each and every year. Since the introduction of diesel passenger cars in the late 1970’s (Sapienza) by German automakers such as Mercedes-Benz, diesel cars have become more popular with the everyday consumer. Diesel engines differ from gasoline engines in their composition and the way in which they use fuel. Rather than using a spark to ignite fuel, an engine running on diesel fuel uses a high compression system to combust the fuel, resulting in higher fuel economy and additional torque

out-of-date carburetor. Throttle body was the first to use a computer to control several aspects of the engine. The throttle body way of fuel injection had two fuel injectors mounted on top of the intake, along with several other sensors all being controlled by the engine control module to achieve ideal running conditions, and the most efficiency(“Fuel Injection Columbia” par. 5). There are several sensors all inputting and outputting information to the engine control module. All of these sensors work

twin powered engine which are used to reduce the pollution. Basically, most of the experts say that the electric engine is used for lower speed and gasoline engine is used for higher speeds. The hybrid car not only consumes less fuel but it also produces less amount of carbon dioxide emission. The hybrid car runs on twin powered engine like gasoline and electric motor that cut fuel consumption, reduce air pollution and conserves more energy (Rinkesh, 2009). Many experts say that one of the biggest

3.2 Effect of Pressure and Equivalence Ratio Fig. 3 (1) - (3) give the effects of pressure and equivalence ratio on ignition delay times of DME/air, n-butane/air and 50%DME50%n-butane/air binary fuel. Note that for all mixtures, ignition delay times decreased with the increase of pressure, meaning that the increase of pressure can promote fuel ignition in current conditions. This is mostly due to the increased fuel concentration and enhanced molecule collision probability at elevated pressures.

Have you ever thought of how driverless cars would change the world. Or maybe you thought that driverless cars would be good for people in the world. Driverless cars would be great for pedestrians and disabled people. But if you are going to use driverless cars so you can read your kindle or watch something on your ipad instead of taking yourself to your destination, then you’re just being lazy. Being lazy is not a good thing because life is supposed to be filled with challenges and the goal in life

Compare the Dodge Challenger and the Chevy Camaro.The Dodge Challenger is overall the better car. "Compare”The Dodge Challenger has better horsepower and RPM. Also the Dodge Challenger has a better selection of engines to choose from. On top of all that the Dodge Challenger has a better 0-60 and a better top speed. Chevy might have better MPG and is cheaper, but with the some research it is easy to tell which is the worst car. This is why the Dodge Challenger is better than the Chevy Camaro.

I have always wondered how many shots it takes for a bb-gun to shoot threw a piece of wood. There are several stages of the history of the bb-gun. A bb-gun is a type of air gun that is designed to fire a spherical projectiles like pellets. The bb-gun pellets diameter is 0.180 inches. The bb-gun was selected for W.F. Markham’s revolutionary new spring-rifle gun that was made of maple and a minimum of metal parts.When adult airguns first started to became widely popular in the United States

or wet market among others. What we are really debating is the price elasticity demand for gasoline? Is it zero? Or what happen if gasoline rises 10% does consumers buy less or more. We will not be playing guessing games but instead we will study and determine what price elasticity of demand for gasoline based on some valid variables.

are much more efficient than gasoline fueled vehicles because diesel fuel vehicles are more versatile and more enjoyable. (Diesel vs. Gas : Which is the Better Fuel ?) Diesel may cost a little more than gasoline but people get more from your money. With a diesel you can haul a lot more payload. In 2014, diesel vehicle sales soared thirteen percent over the previous year’s sales (Diesel vs. Gas : Which is the Better Fuel ?). Diesel fuel is more efficient than gasoline because they have great fuel

power cars. But what exactly goes into making this gasoline? It´s not just millions of years along with heat and compaction to make this liquid. It takes multiple processes to get it to the stage where it can be suitable for the car´s engine. There are 7.4 Billion people living on this planet, so gasoline production has to be quick! Thankfully, it is!, It only takes about 12-14 hours to make a 30,000 gallons of petroleum into gasoline. Gasoline has many good uses, but also, it can damage life on

Electric cars are more economically efficient than their gasoline counterparts. Beginning in 2000, the price of gasoline has reached record prices (Hawaleshka). Higher costs raise a problem, as 71% of Americans report they do not want to pay more gasoline taxes (Leiserowitz). But owning and maintaining an electric vehicle (EV) can provide a solution, saving vehicle owners money that would have been spent on gas. Paying for fuel in an electric car will cost the owner three times less than a 25 mpg

and cons of the use of ethanol in America’s gasoline. It highlights the major downfalls and improvements that come from Ethanol as well as the economic and domestic advantages of ethanol production. It explains the history of ethanol’s use in america as well as its development and subsequent use in fuel. It also explains through credible sources how ultimately ethanol’s advantages far outweigh its drawbacks. Ethanol is already widely used in most gasoline its time the american public is made aware

A variety of plant resources jointly referred to as “biomass” is made into a renewable fuel called Ethanol. Over 95% of U.S. gasoline contains ethanol, normally E10 (10% ethanol, 90% gasoline), to reduce air pollution and oxygenate the fuel. (Ethanol Fuel Basics, 2014) Ethanol is a clean burning, high-octane, high-performance fuel that reduces carbon monoxide and hydrocarbon tailpipe emissions. (KAAPA Ethanol, 2015) The return on an ethanol stock is greater than return on an oil stock because the

approximately 3 percent. Minus three percent off of your mileage will bring It off by 0.6 of a mile. Blending ethanol and gasoline at a ratio of 85 percent to 15 percent is called E85, the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline. Ethanol is alcohol, and alcohol causes corrosion in the fuel system. Metal parts rust and plastic parts become deformed

gas advertisements. Depending on where you go, for example, Exxon, Shell, USA Gas, Chevron you’ve seen the three types of gasoline, which may include premium and normal. Have you ever wondered what’s the difference? Premium gas is advertised as more fuel efficient, environmentally friendly, and is overall expensive. But is premium gas really better for your car? Premium Gasoline must be premium for a reason, right? The definition of Premium is "a high value or a value in excess of that normally or

Gasoline is a petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds refined from petroleum, and is then enhanced with additives. When under enough pressure (such as in internal combustion engines) gasoline tends to auto-ignite causing damage to the components, this phenomena is called "engine knocking.” To plevent this from occuring, refineries add chemical compounds to increase the fuel’s resistance, or octane rating, to

distance and speed. Most of these can only travel up to about 50 to 100 miles without being charged. You just can’t use them for long distant travel as of now, although it is expected to improve in future. It takes a couple of minutes to fuel your gasoline powered car, an electric car can take about 4 to 6 hours to get
