Different types of Motor Engine Structure


Hello readers, welcome to carlistbd.com. 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 Different types of Motor Engine Structure that helpful for all.The complex part that combines everything from the various mechanisms in the motor vehicle to the engine body is divided into two parts.

1) Automotive Chassis - Chassis is the lower part of the automobile - which is attached to the engine, all kinds of the driving system, and all the wheels attached below it.  This chassis is the main part of the car. It is self-propelled - this is the source of the car's speed.

2) The upper part of the car or body (Body) - It contains the upper outer cover of the car, the door, the seat, etc. Nowadays everyone lights the inside of the car by connecting the power connection with the body. Many also add transistors, wireless sets, electric fans, etc.


The next figure has a picture of a frame. The wheel engine and various parts were not attached to this frame. This is the beginning of the chassis.

There is no need to talk about the body of the car. The reason is that the speed of the car has nothing to do with the body. If you want to learn how to repair a car, you need to know more about the chassis - especially the engine and its operating system.


The first requirement for the construction of the chassis is the car frame (with which the various parts of the engine and wheels, etc. are attached to form the complete chassis).


The wheels, however, are not directly attached to the vehicle but are fitted through the springs.

The passengers inside do not feel it for this spring.

The next picture shows the complete chassis of a car with an internal combustion engine. If the engine, shaft, wheels, etc. are attached to it and the body is attached to it, then it is a complete motor vehicle.

If you don't store knowledge about different parts of the engine, you will not be able to understand the working method. So before the different parts of the engine and its work is being explained.



The hypodermic syringes that doctors inject are shaped like pistons, the cylinders, and pistons of automobiles. The cylinder is shaped like a large round tube made of metal. The head of the modern cylinder is fastened with nut-bolts and packing - the head can be detached if necessary.


In that cylinder, the side of the head is closed and a funnel is made to be airtight - it is called a piston.

The body of the cylinder is usually made of cast iron. At the top of it are placed two paths or ports - one with engine gas entering through the port and the other with exhaust gas. Two ports, controlled by two valves.

In L type cylinders, the port stays with the Oval cylinder. There are no single cylinders - a car sometimes has four, six, or even eight cylinders.

The number of cylinders in a modern car is made by welding at the same time. As a result, all the cylinders are made by welding at the same time. As a result, the balance of all the cylinders is correct.

The balance of the cylinder or eight cylinders is correct.

These combined cylinders are called blocks together. Usually, four-cylinder, six-cylinder, and eight-cylinder blocks are made.


Different types of cylinders and their blocks are made in different processes - this is fully explained here.

Cylinder block

Just as the cylinder is made as a block, its piston and its contact with the cylinder are also made together, regulating properly. This is because the number of cylinders that are present at the same time keeps the communication system in order, and the number of pistons is kept at the same time.

The piston and connecting rods of the cylinder blocks that are connected are all connected by a single crankshaft.

This connection system works well, so even if the number of cylinders is large, they do not need to be enlarged. The higher the number of cylinders in the cylinder block, the lower the weight of the flywheel.


The cylinder block will be made in such a way that in four-cylinder blocks when two cylinders are compressed, the remaining four will exhaust.


Compression and exhaustion work in a Cycleway.




Monoblock type

Monoblock systems are made by simultaneously placing cylinders side by side. It has a water cooling system in each cylinder. Nowadays it is used in all modern cars. The advantage of this is-

1. The length is short; 2. The weight is light; 3. The shaft and bearing are less angry. Exhaust etc. are easily 5. The engine can be kept completely cool.


Parallel or single block type

It is not usually found in automobiles - it is mostly used in airplanes or tanks. It has an air cooling system.


1- Gas inlet pipe. 2- Gas outlet pipe. I - entry; E-emissions.


Cylinder valve:

Here's a thing - it's about cylinder bulbs. The cylinders have two ports on top and two valves as described earlier.

The function of the two bulbs in each cylinder is to get the gas in and out. When more than one cylinder is in the cylinder block, his valve will also be more.

There are 6 valves in 4 cylinder block;

The 4 cylinder block has 12 valves;

There are 16 valves in 4 cylinder blocks etc.

There is no complication in installing the valves - because when compression and exhaustion are carried out in a dotted manner, the valves will also work properly.

Again the gas of all the valves is combined to make a way out. The valve that has this combined path is called the overhead valve. 

V type engine:

For large engines, 12 or 16 cylinders are used together.

In these cases, 6 or 8 cakes are made, which are placed on the angle crankshaft like the English letter V. That is why this type of engine is called V type engine. Of course, all the other systems of these engines are the same as normal engines.

Cylinder metal:

Most of the cylinders that are cooled by air are made with large types of Castiron.

Some types of cylinders are made by a special type of ‘Aluminum Alloy’. The cylinders that need to be made lightly are made of aluminum alloy. The cylinders used in airplanes are also made of this metal. If the alloy is good, then it is hard and strong enough.

Cylinder liner:

Usually made of cast iron or aluminum cylinders. After casting, the inside of the cylinder is thoroughly cleaned, separated and a mixed metal tube is cast and placed as a liner in the cylinder. The name of the alloy is ‘Clomidium centered’.

Most cylinders nowadays have good liners. This increases the power of the cylinder on the one hand, and on the other hand, the piston can travel easily. Liners with lubricating oil are more effective. If the liner is worn out, a new liner has to be used - so there is no need to replace the cylinder or piston. This makes the cylinder block long-lasting.

Liners that are cooled with water are called waste liners. And liners that do not require water to cool are called dry liners. What kind of liner is made by mixing aluminum and chromium is called a nitro cast iron liner. It is a very low erosion.

Aluminum cylinder:

The cost of making a cylinder with aluminum alloy is high but it has high heat-expansion capacity. This results in higher compression of the engine. The cylinder whose head can be opened is called ‘Detachable Head Cylinder’. The inside is well carved and the liner can be easily fitted and the cylinder can be repaired easily. The inside can be cleaned only by opening the heads without opening the cylinder block. Thank you all for reading this article.
