From the mid-1800s to today, the internal combustion engine is becoming more and more complex. From minor improvements, to total reconstruction; the internal combustion engine has changed greatly, and is still changing. By the 3000s, who knows what possibilities will await, but for one to understand the evolution of the internal combustion engine, they must be knowledgeable of the history, present, and future. What is internal combustion? Internal combustion is the process of internally burning gasoline to produce forward motion. There are two different types of internal combustion engines. The diesel engine is one and the gas turbine engine is the other. The gas turbine engine is the most commonly used engine in the automobile industry. The principle behind internal combustion is simple. If you put a small amount of fuel, such as gasoline, in a small enclosed space and ignite it, an extreme amount of energy is released. This energy is released in the form of expanding gas (“Internal Combustion”2). The internal combustion engine was invented in 1860 by a Belgian man named Jean Joseph Etienne Lenoir. Lenoir built the first gas powered internal combustion engine that provided a reliable and continuous source of power. Although the engine was powered by gas, it was not gasoline. The engine was fueled by coal gas. The first practical internal combustion engine was based on the experience from the production of steam engines. It was a single cylinder engine, and had slide valves that were used to draw in the air/fuel mixture. The engine was also double acting. This means that the air/fuel mixture was fed into the cylinder alternately from either end of the piston. Then the spark plug ignites the mixture. The engine was a great achievem... ... middle of paper ... ...e of the internal combustion engine, to truly understand its evolution. Works Cited "How Car Engines Work." How Stuff Works. Web. .

Combustion is an exothermic reaction that reacts when in contact with oxygen producing heat and a new product. These reactions are as exothermic as it gets. The general form of a combustion reaction is the reaction between a hydrocarbon and oxygen to create carbon dioxide and water. Hydrocarbon + O₂→CO₂+H₂O. Occasionally, these reactions can release light and produce a flame. To start a reaction, most require a flame to provide heat and initiate the reaction. Combustion is a very common reaction. It's what makes our cars go, and it's what burning is. It is containing carbon which reacts with oxygen to form CO2 and H2O. A simple example of the combustion of Methane, a natural gas, CH4 + 2O2 →CO2 + 2H2O. Another example includes the burning of naphthalene with the equation C10H8 + 12 O2 → 10 CO2 + 4 H2O. The combustion of ethane is 2C2H6 + 7O2 → 4CO2 + 6H2O which is another example. A real life example is the combustion of gunpowder. Gunpowder is a mix of potassium nitrate, charcoal, and sulfur. The potassium nitrate decomposes at a high temperature to provide the oxygen needed. The charcoal and sulfur are the fuels in this reaction. The equation for this reaction is as follows 2 KNO₃ + S +3 C →K₂S + N₂ + 3 CO₂. An incomplete reaction occurs when the oxygen is
When Ford introduced the Mustang in 1964 there was no immediate reaction from General Motors, but by August of '64, just four months after the Mustang's introduction, GM realized the appeal of a four seat sports car. Ironically, the Mustang was created in response to the Chevrolet Corvair Monza!
After the steam engine was created in the early 17th century, many people and companies tried to take that same technology and apply it to automobiles. Nobody was successful until a British inventor by the name of Richard Trevithick created a multi passenger automobile that ran on a power source that was driven by a steam-propelled piston at high pressure (Bellis). Up until the mid 1900’s cars were only produced by specifically skilled blacksmiths, and were very expensive. There were only about 4,000 cars produced from the 1890’s to mid 1900’s (Bellis).
The Automotive, or electric car industry particularly, comprises all those companies and activities involved in the manufacture of electric motor vehicles (EV), including most components, such as engines, bodies and rechargeable batteries or another energy storage device. The industry’s principal products are passenger automobiles. Despite the fact that the first electric cars were produced in 1880s , the advances in internal combustion engines, especially the electric starter, soon diminished the relative advantages of the electric car and became the dominant design in the market. Due to this the EV was almost a forgotten industry staying in the early stage of development, conforming to less than 1% of the automotive stock
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
4. Exhaust: After the Air/Fuel mix has been burnt, the remaining chemicals in the cylinder (water and CO2 for the most part) must be removed so that fresh air can be brought in. As the piston goes back up after combustion, the exhaust valve opens allowing the exhaust gasses to be released. Ideally an engine takes in air (oxygen and nitrogen) and fuel (hydrocarbons) and produces CO2, H2O, and the N2 just passes through.
Thomas Savery invented the first steam engine in 1698. People like Thomas Newcome, James Watt, and Richard Arkwright kept improving the machine over many many many years. Arkwright built the first steam-powered textile plant in 1790. The steam engine used steam to power engines and make them run, like in boats and trains. James Watt steam engine became dominant design for modern steam engines. It also helped bring about the Industrial Revolution.
The world of technology is ever changing and advancing. With the automotive industry in play technology is constantly surpassing what is available today with what can be done for tomorrow. Technology and the automotive industry go hand in hand with constant improvement to components of cars. Due to technology advancement there is competition within the car industry, especially between American car companies and European car companies. European car companies provide their buyers with innovative variety and revolutionary luxuries. European car technology is superior to American car technology due to their safety, entertainment, and luxury features.

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
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.
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).
Before the invention of the modern day engine, lifestyles were completely different. Letters were sent by horse drawn wagons, people traveled by horses and other such animals, often taking an entire day to go twenty miles. The first direct injection fuel engine was not invented until 1923.[1] It only took a year before this engine was put into automobiles, making the lives of the general public much easier. The invention of the engine not only made it possible to travel by road, but also by water and air. Mail was no longer delivered by horses and families were able to travel from one place to another in less than an entire day. However, the affects of the modern day engine can be seen all over the world. Take Los Angeles for example; the city is filled with smog which is from the overcrowding of all the freeways with automobiles. Technology has escalated to a level where engines are no longer made by the working man. Now, engines can be made simply machines and computer based tools. However, these thought of simple ways of creating engines are not as easy as the first seemed. There are many positive and negative aspects of using technology to design engines.
A steam engine is an external combustion that converts heat energy, in the form of steam, into mechanical energy. Steam is generated through combustion of a fuel, i.e. Coal, heating a boiler filled with water, which evaporates to produce steam that expands do drive a piston connected to a flywheel in a rotary motion. The flywheel then transmits energy created to a crankshaft which is used to provide power to machines, such as locomotives, fluid pumps, and machine tools. Waste steam is then expelled from the engine through an exhaust, or can be condensed and repurposed in some steam engine designs (Croft and Tangerman, 1939).
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...
