The piston in the car - what is worth knowing about it? The engine piston is undoubtedly the most important element and part of the cylinder-piston system, in all internal combustion engines, it is made on the basis of a special alloy based on aluminum and silicon, connected by a pin, i.e. a joint and crank. It is the piston that receives the mechanical energy generated during the combustion of the mixed fuel and air mixture. So it participates in setting the crankshaft in motion by pushing it, in addition to the engine piston, it is also to take care of:

The sealing of the working chamber, which is located in the cylinder, allows for a high compression parameter and compression ratio, which translates into a much higher efficiency of the drive unit. The engine piston is also supposed to help cool the cooking chamber, especially if the temperature in the cylinder rises above 2,000 degrees, so it provides warm oil and a sufficiently fresh mixture of fuel and air. As you can see, the piston in internal combustion engines plays a very important role, but often it breaks down in various ways and damages that require immediate repair.

In what situations can the piston be damaged?

Usually, when mention is made of a piston failure, it is a broken timing belt, the pistons collide with the valves, with a consequent deflection of the valves themselves. During such a phenomenon, the piston is also damaged, just like when inside the cylinder there was a sudden increase in temperature and pressure. The effect of overheating of the piston appears, i.e. seizure of its side surfaces, it is no different when we do not have the right amount of oil, or it is simply used up in the world. So if we want to take care of the work of the piston or other parts in our engine, this is another of many situations that requires us to systematically replace not only the oil, but also the air filters. So let's not only remember but also follow such recommendations, tips or suggestions.

The engine piston is an essential component of the cylinder-piston system in all internal combustion engines. Typically made from a specialized alloy composed of aluminum and silicon, the piston is connected to the connecting rod and crankshaft by a wrist pin. Its primary function is to convert the mechanical energy generated during the combustion of the fuel-air mixture into reciprocating motion. Apart from its role in moving the crankshaft, the piston is responsible for:

  1. Sealing the working chamber: The piston ensures a high compression ratio and compression parameter, which contributes to the engine's overall efficiency. It forms a tight seal within the cylinder, allowing for optimal combustion.

  2. Cooling the combustion chamber: The piston assists in cooling the combustion chamber, particularly when temperatures exceed 2,000 degrees. It helps distribute warm oil and maintains a fresh mixture of fuel and air to regulate temperature and prevent overheating.

As evident, the piston plays a crucial role in the operation of internal combustion engines. However, it is prone to various failures and damages that require immediate attention and repair.

The piston engine

There are several situations in which the piston can be damaged. One common scenario is a broken timing belt, which leads to the collision of the pistons with the valves, causing valve deflection and piston damage. Sudden increases in temperature and pressure within the cylinder can also result in piston damage. Overheating of the piston manifests as seizure on its side surfaces. Additionally, insufficient oil or oil depletion can cause piston problems. Therefore, to ensure the longevity and performance of the piston and other engine components, it is essential to regularly replace oil and air filters as recommended.

Taking care of the piston and following maintenance recommendations is crucial for the smooth operation of the engine. Regular oil changes, proper lubrication, and the use of high-quality filters help maintain optimal conditions for the piston and other engine parts. If any issues arise with the piston, such as damage or malfunction, it is advisable to seek immediate professional assistance to avoid further complications and ensure the proper functioning of the engine.

In conclusion, the engine piston is a critical component of internal combustion engines, converting energy from the fuel-air mixture into motion. It serves vital functions such as sealing the working chamber and assisting in cooling the combustion chamber. Understanding potential causes of piston damage and following maintenance guidelines are essential to protect the piston and maintain the engine's efficiency and performance.
