Collaborative Development with Leading Manufacturers
Mahle Thermal Management's Large Engine Components profit center works closely with top engine manufacturers in marine, rail, industrial, and power generation sectors. Their collaboration results in the development of innovative components and systems for efficient and modern engines. From pistons, piston rings, and piston pins to cylinder liners, valves, valve seat inserts, and guides, Mahle offers a comprehensive range of products that can be customized to meet specific requirements.
Cylinder Liners for Every Engine Need
Mahle's cylinder liners are designed to meet a wide range of engine requirements, catering to piston diameters of up to 460 millimeters. These liners are built to be robust, with minimal wear. Produced through a centrifugal casting process, the liners are supplied as ready-to-assemble components. Mahle also provides tailored liners, including those with cooled flanges and deep-hole bores for special cylinder lubrication. Finite element analyses are used to enhance load capacity, deformation properties, weight, and overall service life.
Premium Quality Piston Pins for Four-Stroke Engines
Mahle's piston pins are utilized in four-stroke engines with diameters of up to 150 millimeters. The range of piston pins offered by Mahle adheres to the highest standards of quality, precision, and versatility in applications. Engineers continually work to reduce the weight and wear of piston pins, ensuring optimal performance and durability in engines.
Optimized Performance with Mahle Piston Rings
Mahle provides a range of piston rings tailored for various engines, including compression rings and oil control rings. These rings are suitable for combustion engines with cylinder diameters of up to 320 millimeters, manufactured from cast iron and steel using advanced technologies. Mahle's piston rings are enhanced through high-quality coating processes, offering improved performance and durability. Coatings like chromium ceramic and chromium nitride PVD exhibit excellent wear resistance and low lubricating oil consumption.
Diverse Material Choices for Aluminum Pistons
Being the largest piston manufacturer globally, Mahle offers a diverse portfolio of aluminum pistons, including cast or electron-beam-welded pistons, and composite options with aluminum, nodular cast iron, and steel skirts. Composite pistons are attached to forged steel crowns for exceptional performance. Steel pistons are available with various connection methods like screwing, friction welding, or high-temperature brazing. Mahle's piston selection for large engines covers diameters of up to 580 millimeters.
Integrated Power Cell Units for Enhanced Efficiency
The power cell unit (PCU) incorporates the piston, piston pin, piston rings, and cylinder liners as a complete module. These units are designed for optimal functionality and efficiency by integrating compatible components. This modular approach results in time and cost savings during development while still allowing customization to meet specific needs. Mahle's PCUs offer flexibility and the advantages of a well-coordinated integrated system.
High-Performance Valves and More
Valves, valve seat inserts, and guides form an interconnected system that needs to withstand extreme conditions. Mahle offers intake and exhaust valves in forged and hot-extruded versions, with various hardening and coating options. Valves exposed to high pressures or temperatures can be manufactured as sodium-filled for added durability. This comprehensive range of components ensures top-notch performance and reliability in engine operations.
