such as an electric motor. A device which burns fuel creating heat to perform work is a heat engine. Heat engines can be classified as external combustion‚ such as steam boiler‚ or internal combustion (IC). They can further be divided into the spark ignited (SI) engine or the compression ignited engine (CI). The compression ignited internal combustion engine has two main designs: the four stroke cycle‚ and the two stroke cycle engine. They are both very common throughout the world because of their

article for The Wall Street Journal‚ (15 September 2008)‚ White maintains that despite the focus on mass-marketing ethanol‚ hydrogen and electric powered vehicles‚ the internal-combustion engine will never go away because of it’s value‚ dependability and power (333). White contends that the internal-combustion engine will be dominant years from now. Over the last 20 years‚ auto makers have been diligent in their quest to advance alternatives to petroleum-fueled engines. White argues

ABSTRACT The gas force due to the combustion in the cylinder of an IC engine will cause the piston to move with primary motion and secondary motion. The primary motion of the piston from TDC to BDC is linear in nature. This motion is desired for translation of motion of engine components.

What potential is there to use ethanol as an alternative car fuel? * Ethanol can be used in internal combustion engines if it can be economically produced from renewable resources or subsidized as a fuel to reduce air pollution. * The advantages of using ethanol include its complete combustion with minimal pollution. It can also be made in a number of ways. See the diagram below. 3. What are three advantages and there disadvantages

source as it is regarded to be renewable and more beneficial to the environment. As a car fuel ethanol is blended with petrol in different concentrations. In cars‚ carbon monoxide is produced from the incomplete combustion of petroleum. By adding ethanol which has 35% oxygen the combustion is more complete and there for reducing the amount of carbon monoxide. Within Australia‚ studies have shown that the effects of 10% ethanol have decreased the amount of carbon monoxide emissions. In Brazil 10%

Specific Purpose - To inform my audience about hybrid vehicles. Central Idea - Hybrid car history and different platforms of hybrid vehicles. Introduction I. A hybrid car is a vehicle with more than one power source such as a small internal combustion engine and an electric motor. II. Most hybrids only use gasoline when needed. The electric motor‚ powered by a stack of rechargeable batteries‚ is the primary workhorse for propulsion under low-speed driving. III. When you think of a hybrid vehicle

automobile was first introduced in the 1880s‚ but all combustion engines still have three requirements that must be met to do their job of providing power – air‚ fuel‚ and ignition. The mixture of air and fuel must be compressed inside the engine in order to make it highly combustible and get the most out of the energy contained in the fuel mixture. Since the mixture is ignited within the engine‚ automobile power plants are called internal combustion engines. Most can be further classified as reciprocating

they don’t produce the pollution associated with internal combustion engines. According to the Electric Vehicle Association of Canada‚ or EVAC‚ even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation‚ such as hydropower and nuclear plants‚ can reduce carbon emissions to less than one percent of those currently produced by internal combustion engines. So‚ even in the worst case scenario‚ cars operated

power a diesel engine would suit you. Fuel economy can play a bigger part in your decision. Diesel engines usually have a better fuel economy rating because of the way they don’t waste fuel during combustion unlike the gas-powered counterparts. The combustion of a Diesel engine is just like the combustion of a gasoline engine but in a diesel it’s a little bit different. Diesel engines do not have spark plugs to ignite the fuel; it uses
