2-stroke engine

In the 2-stroke engine industry, sealing segments play a key role in ensuring reliable and optimal sealing between different parts of the engine. Among the different slices used, the R -slice, the NH e-slice and the NE-slice are among the most commonly used.

The R -cut refers to a straight cut folded on the sealing segment. This simple, straight cut ensures a flat and even contact surface between the segment and the sides of the cylinder, thus guaranteeing effective sealing and minimising gas leakage. The R-cut is used in 2-stroke engines to ensure proper compression of the air-fuel mixture and efficient combustion.

The NH cut, also known as the inner notch, has a diagonal shape on the sealing segment. This cut optimizes sealing by providing uniform pressure on the cylinder walls, thus reducing the risk of leakage and avoiding the rotation of the segment in its housing. The NH e cut is often used in 2-stroke engines to improve engine performance and overall efficiency.

The NE cut, also known as the Side Notch, has a trapezoid or bevel section on the sealing segment. This cut is designed to avoid rotation of the segment in its housing and to facilitate insertion and removal of the segment in the cylinder, reducing the risk of damage during assembly or maintenance. NE is commonly used in 2-stroke engines for easy installation and adjustment of the sealing segment.

In the 2-stroke engine sector, the sealing segments with R -cuts, NH and NE are used in various applications, from small motors to bigger and more powerful motors. These segments ensure reliable sealing, minimize compression losses and contribute to the optimal performance of the 2-stroke engine.
