What do pistons do in an engine, and what should you pay attention to?

Whatever the engine type, pistons are the "beating heart. With the crankshaft and connecting rods, pistons form the core of the rotating part of an engine. They eventually provide the power for a vehicle in the engine room. At first, this is still a "linear" movement, which is converted into a rotational movement thanks to the connecting rod. Under an enormous load, especially at higher speeds. In short, everything starts with good pistons you can build on.

An important consideration with pistons is making sure that there is as little friction as possible with the inner wall of the cylinder. This is more likely to result in wear and tear. Too much leeway is unacceptable, as it reduces the piston's adequate power. Piston rings ensure a good seal so as not to unnecessarily lose compression in the cylinder. Every good manufacturer of OE-quality pistons also considers that pistons must be light in weight. After all, the mass of the rotating parts must be contained. That's why most pistons are made of aluminum or magnesium alloy. Other specifications apply to heavy-duty and performance applications (sometimes custom-made). The latest generation of pistons has been significantly improved by contemporary coatings that make the piston stronger and smoother, better performance, and less friction.

About the benefits of Wilmink Private Label pistons

Why Private Label? These pistons are not only attractive thanks to the excellent price-quality ratio; there is also more possible for the buyer than just the standard sizes that are made in large numbers by well-known brands. Oversize pistons are used when the block needs to be drilled. But there are also forged pistons, special pistons with a bowl, or pistons with an oil gallery. In such a case, Private Label is also an option. It means not only OE quality, but also extra personal service. During the final quality check, the finish and coating are also important points of attention. A good example is the WPC treatment, a surface treatment that reduces friction and improves the material.
