Internal combustion engines gain repelling force by high pressure, which composed of combustion of the fuel in the combustion chamber. Depending on this repelling force ,piston starts to move and it supplies the engine power to the required mechanical elements so, runs the vehicle. This is the working principle of internal combustion engines. In other words, internal combustion engines are the machines, which turn fuel’s chemical energy before turning mechanical energy. Combustion occurs inside of the engine that is why, they are called Internal Combustion Engines. In an external combustion engine, combustion occurs outside of the engine.For example in thermal power stations combustion occurs in a steam boiler out of the steam turbine. With the transition of combustion chambers into the engines, automobile industry were developed and compact heat machines were produced. Nowadays electric engine automobiles are produced and launch to the market but, it seems hard to solve the energy storage problem. Batteries are very heavy, it takes long hours to charge and runs out in 160km. They are suitable for urban-use. It is possible to go more than 1000 km with a full tank gas internal combustion engine automobile, but it is not possible to go this much distance with electric engine cars. That’s is why ,bus, track or this kind of vehicles can not be worked with electric or batteried engine system. So, it INTERNAL COMBUSTION ENGINE 2 is not so hard to predict that internal combustion engine automobiles will serve humanity for many years.The three more important aspects of internal combustion engines ... ... middle of paper ... ...d.

Most motor vehicles today use an Internal Combustion Engine (ICE) to give them power to drive down the road; ICEs are a form of a heat engine. Gasoline is burned to push a piston, which in return forces the car down the road. As the gas in the cylinder is ignited and expanded it forces the piston down the shaft. The force is carried through piston, which is connected to a crankshaft. The force moves through the transmission, down the driveshaft, and out the tires. The Otto Cycle is used to turn as much heat into the driving force as possible.
For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.
3.Combustion: As the piston reaches the top of its stroke or TDC, the spark plug fires, igniting the mixture. Due to the high compression of this mixture it is very volatile and it explodes when the spark is introduced. This pushes the piston downward and produces power.
In an internal combustion engine, the fuel inside it is burned in the air at the top of its pistons. Most internal combustion engines are mainly used in small vehicles. In the 19th century external combustion engines were commonly used to power large steamships and trains. The combustion chamber of an internal combustion engine is limited in part. When the fuel is burnt in the combustion chamber, hot gasses can straight away push the piston down. Due to the pressure of the gas being high it quickly increases to follow the piston and to continue pushing on it. As the gas pressure goes low, the gas has then pushed the piston to its bottom place. The heat in an internal combustion chamber is made inside the engine, because it can quickly perform on the engine pistons. This then lets the internal combustion engine to be smaller and lighter than the external combustion. Due to this internal combustion engines are commonly used for mobile applications with low power. In an Internal combustion engine the increase of high temperature and pressure gases made by combustion applies straight force of the engine. Like the pistons, turbine blades or a nozzle. This force changes the component over a distance, which makes mechanical energy. ‘Internal combustion’ refers to an engine which the combustion is alternating.
The invention of internal combustion engines in the early 19th century has led to the discovery of utilisation of cheap energy that is petroleum and this enabled the world to develop and progress into the modern world today. Humans were able to accomplish more work done with little manual labour, using internal combustion engines powered by fossil fuels. Internal combustion engine are mechanical power devices that convert heat energy to mechanical energy with the combustion process taking place in a system boundary (Rolle, 2005). Among the internal combustion engine invented in the 19th century were the Otto engine, Diesel engine and gas turbine engine. Gas turbine engine is one of the popular engines used today due to its high torque per weight ratio relative to other types of internal combustion engines. As explained by Cengel and Boles (2011), the gas turbine engine works on a 6 stages process, namely air intake, compression, fuel injection, combustion, expansion and exhaust (refer to Figure 1 in Appendix 1).

Internal combustion engines are devices which produce work, as a result of the products of combustion as the working fluid rather than as a heat transfer medium. To produce work, the combustion is carried out in such a way that, it produces high-pressure combustion products which can be expanded within a turbine or piston. The

Engineering: [a] diesel engine is an internal combustion engine in which the chemical energy of fuel is transformed into thermal energy of the cylinder charge, in consequence of the self-ignition and combustion of fuel in the engine cylinder after compression of the air charge in the cylinder (p1 Makartchouk).
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
Diesel engines are an important component of society in how they are used efficiently and effectively. Diesel engines have been around since 1892 when inventor Rudolph Diesel was able to achieve his goal of developing an internal combustion engine that can achieve maximum efficiency as seen in the Carnot Theorem. The Carnot Theorem set the standard for determining the maximum
In this different component of internal combustion engine( as internally combusted gas mixture produce power to run a engine ) are discussed.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
Due to the rapid increase of price and scarcity of the fuel, the technological world has focused on alternative for energy saving. Most of the automobiles consumes decent percentage of fossil fuels for their working, so they has to be improved. Automobiles include electronic vehicles, Hybrid Vehicles and Human Powered Vehicles are developing to consume a large mileage per gallon. Instead of finding alternatives for fossil fuel, Designers are trying to improve the vehicle performance by manipulating different parameters of vehicles like engine parameters, Weight, Rolling Resistance and Aerodynamic Drag.
In my undergraduate years, I have acquired a strong background in the fundamentals of basic mechanical engineering, having studied subjects such as Strength of Materials, Thermodynamics, Fluid Mechanics, Heat and Mass Transfer, Design of Machine Elements and Automobile Engineering. Whilst pursuing my diploma & degree courses, my interest for Automotive Engineering grew even more having learnt more on the different types of internal combustion engines, their configuration and importance. However, what I lacked was a practical understanding on these core areas of Automotive Engineering. To gain a better understandi...
