Important Parts of an Internal Combustion Engine
Today I will try to teach you about the Internal Combustion Engine. This is a heat engine when the fuel is inserted into the cylinders, then the combustion work is completed. After the burning force is completed, high temperature and abundant pressure force are created. Using some mechanisms, the pressure is used to rotate the car’s wheel. Some main parts work together to convert the chemical energy into mechanical energy in an engine. And all of these parts work together and it’s called an engine. Today I will tell about these parts. How do these parts work?
Important main Parts of an Internal Combustion Engine:
The Cylinder block, Cylinder head, Piston, Piston rings, Connecting rod, Crankshaft, Engine bearing, Engine bearing, Valves, The Spark plug, The Injector, The Manifold, Camshaft, Gudgeon pin or piston pin, The Pushrod, Flywheel.
The Cylinder block
The cylinder block is the main part of the Internal Combustion Engine. A cylinder is a part that takes energy and produces heat. Cylinder block can guide the piston. As it is directly connected to the product, so it needs to be cooled. For cooling the cylinder, a water jacket is
used or fan is used for cooling. At the bottom end crankcase is bolted and At the upper end of the cylinder, the cylinder head. There is a burning chamber on top of the cylinder. As the pressure and temperature are made by fuel ignition, so the chamber materials must be of high quality. So high grade cast iron is used to create engines
The Cylinder head
Two holes are kept on the cylinder head, one-hole use for takes fuel and other hole use for exhaust. Two valves are used to control intake fuel and exhaust. The inlet exhaust valve, valve, injector, spark plug, etc. The cylinders are bolted over the head. the cylinder block is used to seal the cylinder head and not to allow entry and exit of gases on cover head valve engine. The cylinders are made by casting the head by iron or aluminum. The Cylinder head is built by forging or casting.
The piston is the main part of an engine and the support of Crank Shaft is connected with a connecting rod. The piston’s basic structure can be divided into top, head, and skirt. The main part of piston top flame and its shape is related to the size of the chamber of combustion.
A piston-cylinder should have a proper fit so that it can freely travel inside the cylinder. If the cylinder and piston are a tight fit, then it will become very hot so that the cylinders will be stuck inside. If the loss is too much then the air will get out and the pressure will be reduced. The piston is decorated with a fine seal fit and the piston ring among the piston and cylinder. This ring is entitled into grooves which have been chopped in the piston.
The Connecting rod:
The Connecting rod is an important part of the Internal Combustion Engine. By sending the power produced by the cylinder head to Crankshaft, it is called the connecting rod. Connecting rod connects the piston to the Crankshaft, so we get the rotation speed from Crankshaft. The Connecting rod converts the reciprocating motion of the piston into the rotary motion of the crankshaft. The piston has two connecting ends, one edge is smaller and the other end is bigger. The small edge is connected to the piston and the big edge is connected to the crankshaft. These are connected using piston pins. The connecting rods are made of chrome, nickel, and chrome vanadium steels. The engines which are small in size, the connecting rods are usually made of aluminum.
Parts of connecting rod
- Small end
- Connecting rod Bolt
- Crankpin bushing
- Connecting rod
- Piston pin/gudgeon pin
- Big end/large end
The crankshaft is called the heart of the Internal Combustion Engine. Crankshaft works as a powerful part of the engine. It transmits power of the engine to the flywheel. The reciprocating trend of piston turns into a revolving speed by Crankshaft. The crankshaft is connected through the bearing. As a result, the crankshaft can easily rotate. Crankshaft’s size and shape depending on the number and layout of cylinders. The crankshaft is usually manufactured by forging steel. It made by graphite or cast aloe to reduce the price of the engine and suitable for everyone,
Various parts of the Crankshaft:
- Crank nose for pulley
- Crank nose for pulley.
- Mount for the camshaft drive sprocket
- Main bearing journal
- Main journal oil way to lube crankpin journal
There is a need bearing in the engine where there are rolling parts. The bearing can works easily to moving parts of the engine.
The crankshaft is supported by bearing. The large part of the connecting rod is attached to the bearing by the crank pin. The crankshaft can turn into the bearing. The main functions of bearings to reduce friction in these moving parts. Sliding and rolling types are used in the engine. The sliding-type bearing is called bush. The sliding-type bearing is used to attach the connecting rod to the crankshaft and piston. The rolling and ball bearing are used for support crankshaft and it can rotate freely. Generally, the typical bearing is made of steel or bronze Metal. See Full Description See our other posts for more details.,/p>
