Goetze has established itself as one of the global leaders in piston ring innovation. As part of DRiV and Tenneco, the Goetze brand continues to deliver reliable solutions that meet the demands of modern engine performance, emissions, and durability. In this first part of our Goetze series, we focus on the importance of piston rings and highlight what makes Goetze a trusted name among engine professionals.

The Critical Role of Piston Rings

Piston rings are essential for maintaining optimal combustion, transferring heat, and preserving compression in an engine. When these rings fail or wear out, the consequences can be significant: ranging from poor fuel economy to total engine breakdown. 

In addition to the compression springs, the oil scraper spring also plays an essential role in controlling oil consumption. This ring removes excess lubricating oil from the cylinder wall so that it does not enter the combustion chamber. Wear or contamination of this ring can cause oil consumption to increase dramatically, resulting in smoke formation and increased emissions. Goetze also pays close attention to this component, using high-quality materials with unique running-face profiles (LKZ) and precise tolerances to ensure a reliable seal and minimal oil loss.

For engine rebuilders and mechanics, choosing the right piston rings is vital, and Goetze offers some of the most advanced solutions available today.

Coatings That Set the Standard

Goetze's piston ring technologies include highly engineered coatings designed for superior performance under extreme conditions:

• CarboGlide: A diamond-like carbon coating that reduces friction and wear, enhancing engine life and efficiency.
• DuroGlide®: Known for its exceptional wear resistance and ultra-low friction properties, ideal for Euro 6 diesel engines.
• GDC®:  Coats the surface of the rings with nano-sized diamond particles and improves the strenght against wear & scuff resistance & provides the possibility to develop more efficient engines with higher cylinder pressures.

These coatings help reduce oil consumption, improve fuel economy, and ensure long-lasting engine performance.
