Short Description of Motor Car Flywheel, Bearing and Engine Valve


Hello readers, welcome to We would like to thank you, those of you who read our blog and visit the site regularly and inspire us to move forward. Today we want to discuss with you all about the motor car Flywheel, Bearing and Engine Valve short description that helpful for all. 


The flywheel is a cast - a heavy wheel made of iron - attached to the rear flange of the crankshaft. The ring gear is mounted on it and the teeth are cut in this ring gear.


From these teeth a Bendex is attached to the self-starter - there is a hole in it called Blind Hole. In it, the clutch is attached by a spindle ball bearing to the shaft. It does about 4 things.

(1) carries a dead stroke; (2) maintains engine speed adjustment; (3) the handle helps to be used if the self-starter is not used; (4) The clutch is operated by.



As mentioned earlier, connecting rod and crankshaft are connected with bearings. The crankshaft at both ends is also connected by two or four bearings. Because without bearings, speed cannot be transmitted to them. The ‘gunmetal bush,’ is used for bearing the ends of the gauge pins of the connecting rod. িন The pin works in some cases firmly attached to the piston. Always keep the dirt away so that the pin does not scratch or cut on the cylinder.


A good bearing always requires a bush in the hole at the small end of the connecting rod - it works well. Big end bearings of connecting rods are extremely necessary. It is made in two parts. These two parts are attached to null-bolts. These bearings are essential for motion, just as the knees, shoulders, and other joints in the human body are needed for movement.


The ‘Big End Bearing’ has an anti-friction or white metal liner. This type of liner is cast directly or individually on bronze metal over the stiffness of the connecting rod and engraved on the lead, the size of the crank pin. At the junction of the two parts, many thin metal sheets are given - they do a lot of spring work. This also helps in tightening the bearings well.


White metal bearings work quite well. But where there is more pressure on the bearing, oil filters are added. The bearing can work easily. In cases where compression is high, these metal bearings are not very effective. In all engines with high compression, the bearing ruptures or breaks as a result of the pressure. That is why it is specially made by mixing the main bearing lead and bronze of the modern engine. It is quite strong and can withstand any high pressure. Kub is a precious metal so the liner is always used in it. Cadmium, nickel, copper, magnesium, and silver have also been mixed to form a very hard and strong metal.

Engine valve

As mentioned earlier, the function of the bulb is to control the pressure of the gas. The engine will always be good enough to be tough enough. This valve cannot withstand pressure unless it is hard. It is easy to assume that the valves have to withstand a lot of pressure. Inlet valves are always made of nickel-chrome steel. Nowadays these valves are also made with chromium steel or stainless steel. Carbon, Helicon, and Manganese are also used with it. Exhaust valve, made of nickel steel.

Valve seating

The valve seating of ordinary cast-iron cylinders does not give bad work. But the special alloy steel site is not durable for long. They are attached to the cylinder by a screw or by pressing. Seating valves of many engines - made of a type of material called stellite. The seats are quite stiff - special cutters are used to cut them.


The sum of the valves

Usually, the valve seat is placed at an angle of 45 degrees to make the valve. This verb often has more than one. If the valve is more than one, its angle is right and its work is better in it. In most cases, the engine valve is made by attaching the valve seat or multiple seats by a special type of screw.


Overhead valve

Earlier, when describing the cylinder, it was said that many times multiple valves of different cylinders are connected by a duct and an overhead valve is placed on top of it. So the pressure falls more on the overhead valve. It needs to be made of special hard metal to withstand high pressure. The more cylinders there are in the block, the greater the number of valves. As a result, the overhead valve needs to be further strengthened.


The size of the overhead valve is larger than the normal valve. The larger its seating, the greater its power. Overheads are usually made of a special type of steel mixed with nickel-chromium. It is also placed at an angle to the mouth of the hole and it is attached by nuts and screws to form a valve. This is seen to be better used in Ford engines. Overhead valves are usually mounted at an angle. There are different types of engines. An image of the overhead valve is given in the figure on the front page.



Its main function is to lift the valves from their position by the cam located in it so that the gas in the cylinder can easily enter or exit. Cams are needed to lift the valves. These are taken down again with the help of a compression spring located in the valve stem.  The force of the springs should be such that the valves can be easily pressed in place. When the spring breaks, the valve is not working properly. As a result, the work of the cylinder is stopped.

The camshaft is now made of chromo-nickel. It is also made of various alloys. These are quite hard metals. The cams are forged together with the shaft.

The engine has exactly twice the number of cylinders in the camshaft. Two cams are required for each cylinder. One for the inlet valve and the other for the exhaust valve.

They are also needed to run the lubricating oil pump, to run the engine oil pump, to turn the ignition distributor, to run the engine oil pump, and to turn the ignition distributor. The shaft is made by forging 3/4 more helical toothed pinion together. The pinions have several teeth and a pinion of the timing chamber at the front end of the camshaft. The engine and its operation cannot be understood without knowing all these parts, in short.


Gas inlet and exhaust pipe

The pipe through which the gas of the cylinder enters is called the inlet pipe. The path that carries gas from the cylinder to the berry is called exhaust pipe. It has already been said that these two pipes usually have valves attached to them. They are called inlet goods and exhaust valves. Usually, both of these are made of steel - because they also have enough gas pressure. The diameter of these two pipes is usually one inch to one and a half inches.
