Transcript of The Internal Combustion Engine

BY: Craig Panek & Kennedy Roukema Internal Combustion Engine What is it? The Internal Combustion Engine is a modern day engine used for many common devices of today. How it Works What increases in knowledge allowed for its development? What are some drawbacks of the engine? Different Types: THE END Why did it Work? - The Science Involved. There a multiple of different kinds of combustion engines; the most common kinds are the four-stoke and two-stroke. The four stoke is commonly seen in today's vehicles (almost every vehicle today uses one), as well as things like dirt bikes. The two-stroke is used for things like mopeds, and jet-skis, as well as some dirt bikes. An Internal Combustion engine works off of the principle that if you a put a ignite a tiny amount of a high-energy fuel in a small space, you will create a large amount of energy.
A four stoke internal combustion engine is the most common type. The four stroke engine uses a cycle of four stokes to turn the gasoline's energy into motion energy. This first stoke is the 'Intake' where the engine intakes a mixture of gasoline and air. The next step is 'Compression' where the piston compresses the mixture making the explosion more potent. After that is 'Combustion' where the spark plug ignites the fuel/air mixture and creates the explosion. Finally the fourth stroke is 'Exhaust' where the exhaust fumes exit the cylinder though the exhaust pipe.

The internal combustion engine has many different types like the four stroke and the two stroke, and we've learnt the different processes for them, but why exactly does it work? Well we learnt that putting high-energy fuel into a small place and igniting it makes a lot of energy. That is pretty much the basic concept of the engine. When high-energy fuel, is put into a small chamber and inginited, and then again, and then again, you create a lot of energy able to move things such as cars, trucks, dirt bikes etc. An increase in knowledge that helped the initial creation of the engine was Christian Huygen’s Gunpowder engine. This engine used the idea of using the gas produced from explosions to drive a piston forward. Robert Steele was looking for a different source of energy than steam, and lodged a patent for a piston engine fuelled by the gas from tar and oil, ignited by a flame. Phillipe Lebon improved on his invention, and invented as engine that used coal gas ignited by an electrical spark. That was the Internal Combustion Machine. The creation of this model allowed N.A. Otto and Eugen Langen to create the Otto engine, a version of the internal combustion machine that was more efficient. And that invention lead Gottlieb Daimler to invent an internal combustion machine that is fueled by petroleum. This was powerful enough to power road vehicles. Two - Stroke Four - Stroke Six - Stroke Diesel Engine http://upload.wikimedia.org/wikipedia/commons/3/31/2-Stroke_Engine_ani.gif A two-stroke is a type of internal combustion engine which completes a power cycle in only one crankshaft rotation and with two strokes (up and down movements) of the piston. These engines are used for small, portable, or specialized machine applications like snowmobiles, model vehicles,lawnmowers and dirt bikes. A four-stroke is an Internal combustion Engine in which the piston completes four strokes (intake, compression, power, and exhaust) http://upload.wikimedia.org/wikipedia/commons/d/dc/4StrokeEngine_Ortho_3D_Small.gif The six- stroke is based on the four-stroke, but more complex, and more efficient. http://upload.wikimedia.org/wikipedia/en/3/38/M4%2B2anim.gif A diesel engine is a type of internal combustion machine that uses the heat of compression to initiate the ignition that burns the fuel in the compression chamber. Internal combustion engines generally use either gasoline or diesel for their fuel, and both are very bad for the amount of carbon dioxide emissions. Another drawback to the engine is that it relies on gasoline and diesel for energy sources which rely on fossil fuels to be mined, which can be bad for the enviroment. Combustion engines are mainly heat engines.This meaning that the engines creates a lot of heat, which is energy not turning into movement (or energy wasted).
