Valve Train Systems and Components
Valve train systems play a crucial role in controlling the gas exchange process within an engine, offering significant opportunities for optimizing combustion. Components within the valve train system are exposed to high mechanical loads, compounded by increasing combustion pressures and temperatures. MAHLE Thermal Management offers a range of solutions, including intake and exhaust valves in forged and hot-extruded versions for gasoline and diesel engines of varying sizes. These valves are available in a multitude of materials and can be strengthened, hardened, nitrided, or chrome-plated depending on the stress levels.
Camshafts for Enhanced Engine Efficiency
In the pursuit of lightweight construction and low-friction bearings, camshafts remain vital in enhancing engine efficiency. MAHLE provides a diverse selection of camshaft designs for different applications, focusing on variables like service life, cost, weight, noise, and extra functionalities. The company's assembled camshafts, constructed from precision steel pipes with steel cam lobes, offer significant benefits in optimizing the overall valve train, with a weight reduction of up to 45% compared to cast or forged camshafts. These assembled camshafts are flexible and modular, adapting to varying design requirements efficiently.
Quality Production of Cast Camshafts
MAHLE's production of cast camshafts primarily utilizes chilled cast iron, ensuring durability and performance. To meet stringent rolling contact requirements, inductively hardened cam lobes can also be incorporated. The company's advanced, automated production facilities guarantee precision and consistency in producing cast camshafts. By utilizing modern machining centers and fully automated CBN grinders, MAHLE ensures high-quality output while catering to a wide range of standard and specialty materials for specific customer needs.
