Internal Combustion Engines Essay

2932 words - 12 pages

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
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 are horse power,torque and spin. Torque is the tendancy of a force to rotate an object about an axis.It is also called torsion force or spinning force. The SI unit for torque is the (N-m ).Horse power is a kind of power unit which determines the power of electric and internal cumbustion engines.Horse power is equal to 736 Nm work in one second. Spin is a round tour of an object which stars from a certain point. The SI unit for spin is the (d/d) or (rpm).

‘’ The cycle which composing petrol engine’s working principle called four stroke cycle or Otto cycle. It was invented in 1876 in Germany by German engineer Nikalous Otto. ‘’ (WİKİPEDİA, n.d)
The first petrol engine has two piston displacement and has the principle of guzzling the total petrol and poping it out. Nowadays the petrol engine’s working principle is as below ;
The clean air taken in to the intake shaft goes to the cylinder as fuel and air mixture by the edge of injection with spraying. In the combustion chamber which is positioned on the top of the cylinder,homogenous like air and mixed gas get pinch and get burn with the help of the plug.With...

The Physics of a Diesel Engine

927 words - 4 pages 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 are basically two types of diesel engines, two-stroke and four-stroke. In a two-stroke engine the piston is forced from the top of

722 words - 3 pages , 2008). Lately researches have been focusing on using hydrogen as an alternative fuel in internal combustion engines in the hybrid system vehicles. In (SI) engines hydrogen can be used on its own as a sole fuel by injection or carburetion, but in (CI) engine, however, H2 cannot be used as a sole fuel due to its higher self ignition temperature, but it can be used in the dual fuel mode. Hydrogen has been used as a fuel in ICEs, fuel cells and as

The Internal Combustion Engine

852 words - 3 pages The internal combustion engine has become an integral part of the lives of every person on earth. They’re the devices that have allowed us to cross continents reliably, generate electricity in remote areas and fly around the world in a matter of hours. All these engines do is burn fuel and convert its energy into work. It’s these heat engines that have really changed the world. However the convenience they bring has come at a great cost. The

By the second-law analysis of internal combustion engines fuelled with n-dodecane (n-C12H26), light gaseous fuel (CH4) and an oxygenated (CH3OH), Rakopoulos and Kyritsis [4] found that the lighter molecular weight fuel can achieved the higher efficiency at the same equivalence ratio of operation due to the less entropy generation in the combustion

Hybrids vs Gasoline dependent cars

1044 words - 5 pages gasoline. Hybrid cars combine the energy generated from gasoline and electricity to power them. They have the traditional internal combustion engine for gasoline, an electric motor for electricity, and a generator. Internal combustion engines generate power through a type of chemical reaction called combustion. The reaction requires for gasoline (which is made up of many carbon and hydrogen molecules) and oxygen in the presence of heat to

Hydrogen: Is it worth it?

1002 words - 5 pages . The good thing about Hydrogen is that it can be used in internal combustion engines like the ones we use today with our gasoline-powered cars. Hydrogen has a high amount of energy in its chemical bond, liquid Hydrogen boils at –252.77 degrees Celsius, and has a density of 70.99 g/l. Because of these characteristics, Hydrogen has the highest energy-to-weight-ratio of all fuels; one kilogram of Hydrogen has the same amount of energy as 2.8 kilograms
