What is Internal Combustion (IC) Engine

What is Internal Combustion Engine IC engine is an engine which mainly consists of one cylinder. To keep the cylinder cool, water keeps flowing in the water jacket made around the cylinder. Cylinders of small engines have fins on them to keep them cool. A piston in the cylinder performs reciprocating motion. To make the piston gas-resistant, piston rings are attached to the piston. The piston is connected to the short end of the connecting rod by a gudgeon pin.

Definition Of Internal Combustion (IC) Engine

The cylinder has entrance and exit holes for the entry of working medium and system of liquefied gases. These holes are opened and closed by the inlet valve and the catharsis valve respectively. A valve mechanism is used to open and close the valves. The opening and closing of the valves in the cylinder head is accomplished due to the movement of the push rod and the rocker arm by the cam mounted on the cam shaft. The camshaft is driven by a timing gear or chain through a frank shaft. In a four stroke engine, the speed of the cam shaft is half the speed of the back shaft, that is, when the frank shaft makes two revolutions in a complete cycle, the cam shaft makes one revolution.

In a petrol engine, a spark plug is placed at the top of the cylinder to generate flutter for the combustion of a mixture of petrol and air inside the cylinder. This plug generates electrical vibrations at the end of the compression stroke. In a diesel engine, an injector is installed in place of the spark plug. This injector injects diesel into the cylinders in the form of very small particles at high pressure in the compressed air up to high pressure and temperature, which immediately starts the combustion of the fuel.

Working Of Internal Combustion (IC) Engine

When the piston in the cylinder moves down, the suction valve opens and the mixture of air and petrol in a petrol engine and only air in a diesel engine enters the cylinder. When the piston moves back up in the opposite direction when it reaches the bottom, both the valves remain closed, causing the mixture or air to be compressed, thus increasing both the pressure and the temperature. If there is a petrol engine at the end of the compression, What is Internal Combustion Engine. the mixture gets ignited due to the spark generated by the spark plug, but if there is a diesel engine, then the diesel fuel enters the cylinder under high pressure from the injector and the high temperature generated by the compression causes the fuel cylinder to ignite. It lights up as soon as you enter.

The piston is pushed down by a force due to the influence of the gases obtained by this type of combustion of fuel. At this time there is expansion of gas due to which work is obtained. When the piston moves back upwards, the exhaust valve opens and the laxative gas exits the cylinder into the atmosphere. This reciprocating motion of the piston is converted into rotational motion with the help of connecting rod and bank and keeps rotating by applying crack shaft.


Various Parts Of Internal Combustion (IC) Engines

Following are the main parts of IC Engine–

1. Cylinder- It is a cylindrical shape. In which a piston does retrograde motion. These are usually made of gray cast iron. The cylinders of small engines are made of aluminum alloy. This metal is lighter and more good conductor of heat. In multi-cylinder engines, all the cylinders are molded together in a single cylinder block, the inner surface of the cylinder is polished by proper grinding and honing. Large cylinders are fitted with separate liners that can be replaced when worn out. Air cooled engines have fans on the cylinders and water jackets are made for cold water to flow in the cylinders of hydro cooled engines.

The cylinder head is fixed on the upper part of the cylinder block. Combustion chamber is made in the cylinder head. To prevent corrosion, a top gasket is installed between the cylinder head and the cylinder block. For cooling, windshields or water jackets are also made on the top of the cylinder. This head is also of gray cast iron or aluminum alloy with valves, spark plugs or injectors attached to the cylinder head.

2. Piston- Piston is an important part of the engine. It converts the chemical energy of the fuel into mechanical work. The piston performs reciprocating motion in the cylinder. Pistons are usually made of cast iron or aluminum alloy. The different parts of the piston are shown in Fig. 11.3. The upper part of the piston is called the head. The ring grooves are cut on the upper part of the piston’s circumference. The area between the two grooves is called the land. The part below the last groove is called a skirt. The skirt has two bosses facing each other to hold the piston pin.

Thus the piston rings have the following functions–

  1. This creates a pressure seal between the piston and the cylinder so that high pressure gases from the combustion chamber cannot enter the crack case.
  2. Pistons make way for heat to flow from the top to the cylinder wall.
  3. Lubricants control the flow of oil. prevents it from entering the combustion chamber.

3. Connecting Rod – The connecting rod is a connection between the piston and the frank shaft. A simple type of combinatorial bar is shown in Fig. 11.4. Its small end is connected with the piston by the gajon pin and the big end with the throw pin. The function of the connecting bar is to convert the reciprocating motion of the piston into the rotational motion of the Frank shaft. The connecting bar is [-cut] and made of forged steel and nickel steel. It is made by drop forging method.
The large end of the connecting bar is split in two so that it can be easily bolted to the frank pin. There is a bearing in the big end which is made of low carbon steel and on it copper-lead, copper-color. Lining made of Ranga-antimony-copper etc. is kept.

4. Bank shaft – The reciprocating speed of the piston is the rotation of the back shaft. It is like a solid eve. And a bush of phosphor-brose could be attached to it and could be tightened with a screw. This small end is hollow from the piston rather than a piston pin. The distance between the center of the back shaft and the frank pin is called crank throw. It is half of the piston stroke. The body of the back case contains the main bearings, to which the crack shaft is supported. The ends of the back shaft which rotate in these main bearings are called generals. The number of main bearings depends on the number of cylinders and the design of the engine. With more main bearings, the frank shaft is well supported, thus reducing vibrations. The front end of the back shaft is fitted with a large hand lever nut, fan belt pulley and vibrating damper, and the rear end is fitted with a swivel wheel.

5. Cam Shaft- The function of cam shaft is to open and close the valves. There are many caterpillars on the lower shaft. There are two cams for each cylinder, one for the inlet valve and the other for the exhaust valve. Apart from this, there is an eccentric to drive the money pump and a gear to drive the distributor. boss) the cam shaft gets its speed from the frank shaft. These two are connected by timing gear or timing chain. The number of gear teeth of the cam shaft is twice the number of gear teeth of the crack shaft. Thus, when the cam shaft completes one revolution and the back shaft completes two revolutions, both the valves open and close at once. what is internal combustion

6.Valve- A valve is a device that opens and closes a path. Four stock engines each have a posolve valve—the inlet valve and the catharsis valve. Through the inlet valve, the air or air-petrol mixture exits the cylinder into the cylinder. When the valve is closed then this valve will be in its seat life. Therefore, the valve surface and valve seat should be properly seated at 30° or 45° angle, otherwise there will be corrosion of the feed. Therefore, the surface of the valve is made of Tisha couple and the catharsis valve is usually made of silicon steel. Is salute. The inlet valve is made of nickel chrome steel and the catharsis valve is opened and fired.
