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 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).
PETROL ENGINE’S RUNNING
‘’ 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...
