If you're wondering about the most important tool in car engines, the crankshaft is the answer. This essential part is indispensable in internal combustion engines, and it can be said that it is the true engine of the vehicle.
Many people are aware of its existence, but few of them know about its function and importance. Therefore, in this article, we will get to know the crankshaft better.
What is a crankshaft?
CrankshaftIt is a crucial part in internal combustion engines, responsible for converting linear motion into rotational motion, enabling the engine to operate smoothly. It is installed parallel to the engine's main axis, consisting of a main rod and a set of primary arms linked to it. These arms are mounted in a way that allows them to continuously rotate.
How does the crankshaft work?
When combustion occurs inside the engine cylinder, the energy is transferred to the piston. The piston then moves downward, causing the main arms of the crankshaft to move downward as well, and then the piston returns to its original position, leading the arms to move upward. This continuous rotational movement is maintained thanks to the main arms of the crankshaft.
The Importance of the Crankshaft
The crankshaft is one of the main components in internal combustion engines, as it converts linear motion into rotational motion, allowing the car to move smoothly, safely, and efficiently. Furthermore, the crankshaft affects the engine’s torque as it helps provide the necessary power to move the vehicle. Therefore, any defect in the crankshaft can lead to a decline in engine performance, an increase in fuel consumption, and increased environmental pollution.

Types of Crankshaft
The Separated Shaft
An essential part in car engines and other vehicles, it consists of a rotating shaft mounted in bearings, which converts the combustion motion inside the cylinders into a rotational movement.For the movement of the wheelsThis type is used in four or six-cylinder car engines. The shaft consists of four main sections.
Part One: This part is connected to the engine and moves in sync with the movement of the cylinders.
Part Two: This part is connected to the first part and revolves around it, along with the movement of the cylinders.
Part Three: This part connects to the second part and converts rotational motion into linear motion, allowing the car to move forward or backward.
Part Four: This part connects to the third part and can be relied upon to produce the required power for motion.
Steel Crankshaft
The crankshaft is a part of the car engine that consists of a solid rod connected to the pistons in the cylinders. It converts the linear motion of the pistons into rotational movement, generating the necessary force to drive the car.
It is characterized by its high durability and is used in engines that require a large torque.
Dual Crankshaft
The dual crankshaft is a part of the car engine that contains two cranks on the axis, instead of the regular crankshaft that contains one crank. This type of shaft is characterized by improving the overall performance of the car, increasing power, and enhancing the vehicle's response, therefore, it is a common choice for sports car engines.
It is characterized by the presence of dual arms, which leads to increased strength and stability.
What are the causes of crankshaft damage?
Sometimes, damage occurs to the crankshaft, which functions as the heart of the engine. If you are experiencing this problem, it is essential to understand the causes that led to the damage of the crankshaft, which are:
Wear and tear significantly affect the shaft due to the continuous friction between different parts in the engine, which increases the rate of wear and tear over time.
Regular maintenance for oil change and oil filter replacement should be done routinely to maintain oil cleanliness and reduce the chances of corrosion.
Avoid running the engine aggressively and quickly at the start of the car.
Avoid driving at high speeds in harsh conditions such as hot or extremely cold weather.
Do not leave the car in extreme heat or severe cold.
Maintaining your car regularly is the most effective way to avoid axle damage. Periodic maintenance, oil changes, and the installation of high-quality spare parts are necessary to keep it in good condition.
Maintenance and Repair
Every car owner must ensure regular maintenance of the crankshaft, as it can wear and get damaged due to daily vehicle use. Negligence in maintenance can cause problems with the main rods, which can affect the overall engine performance.
In the event of any problem with the crankshaft, repairs should be made quickly to avoid exacerbating the issue. Technicians specializing in service centers can carry out the necessary repair and replacement operations, and ensure that the shaft is operating efficiently and smoothly.
The Conclusion
The crankshaft is one of the key components in internal combustion engines, as it facilitates the conversion of linear motion to rotational motion and provides the necessary force to move the vehicle. Given the variety of crankshaft types, every car owner should make sure to maintain it regularly to avoid problems that affect the engine's performance.
