Bearings
In modern engines, the demand for higher operating temperatures, pressures, speeds, and lower emissions has never been greater. This necessitates the use of innovative concepts and materials in cylinder components to enhance performance. One crucial component, bearings, must improve load capacity and reduce wear and friction to meet the evolving requirements for CO2 reduction. The challenge intensifies in stop-start or hybrid systems where the engine frequently switches on and off, subjecting the bearings to high loads during the starting process.
Connecting rods
Connecting rods play a vital role in transmitting forces and motions within an engine. With engines striving for higher performance, connecting rods are facing continuous stress and performance demands. The industry trend leans towards lightweight components, and MAHLE's connecting rods are designed to meet this challenge head-on. With high-strength materials and innovative manufacturing processes, MAHLE can exceed current requirements for connecting rods.
Cylinder liners
Cylinder liners face significant mechanical loads from the piston motion and must endure high ignition pressures and speeds. To minimize wear, the cylinder surface should be smooth, ensuring proper lubrication between moving parts. The quality of the running surface directly impacts oil consumption and component wear, making it crucial to have efficient cylinder liners to enhance engine longevity and performance.
Piston pins
MAHLE's piston pins are crafted with precision and versatility, incorporating high-quality materials and innovative manufacturing techniques. These advanced piston pins are designed to withstand high stress levels and are coated with PVD or DLC for reduced wear and improved friction. The intricate forms achievable through modern manufacturing processes enhance stress resistance, offering superior performance in demanding engine environments.
Piston rings
As engines operate under increasing temperatures, pressures, and speeds, piston rings face escalating loads. To address this, MAHLE continuously develops new coatings and ring designs to improve wear resistance, reduce friction, enhance sealing capabilities, and ensure break resistance. With a wide array of compression rings and oil control rings available in various designs, profiles, and technologies, MAHLE provides tailored solutions for every engine, optimizing performance and efficiency.
