Optimizing Engine Lubrication and Cooling
In the realm of passenger cars, ensuring reliable lubrication of moving parts with oil is crucial to reduce mechanical friction and prevent damage in the engine and transmission. A key aspect of this process is the oil circuit, which serves as a mechanism for dissipating heat. MAHLE's oil management solutions focus on enhancing the overall system of engine lubrication and cooling by integrating various functions. These functions include filtration, cooling of the lubricating oil, oil mist separation, pressure and temperature control sensors, oil pressure regulation, crankcase pressure regulation, and the option for a fuel cooler. By utilizing advanced materials, particularly high-performance plastics, MAHLE achieves significant cost and weight savings. Additionally, the incorporation of environmentally friendly filter elements that are easy to replace and dispose of contributes to sustainability. Modern filter media and manufacturing processes used in long-term filter elements extend service intervals, improving overall efficiency and performance.
Oil Management for Alternative Drives
As part of MAHLE's dual strategy, the company continues to innovate solutions for optimizing combustion engines along with advancing e-mobility. The oil management module for alternative drives has been specifically designed to meet the unique requirements of electric powertrains. This module integrates an electric oil pump, filter, and thermal management system into a compact unit that cools and lubricates the transmission and electric motor. Emphasizing weight reduction, space utilization, and NVH qualities, this specialized solution offers efficient and reliable performance for electric vehicles.
Enhanced Heat Exchangers for Efficient Oil Heating and Cooling
MAHLE's oil heating and cooling systems feature heat exchangers with a lamellar design, providing a balanced thermal cycle for lubricating oils in the engine and transmission. These heat exchangers facilitate rapid heating of the lubricant during cold starts, reducing fuel consumption. They also prevent overheating and premature oil aging at high temperatures, allowing for extended oil change intervals. The latest heating and cooling modules from MAHLE not only manage temperature regulation but also channel guidance and filtration of the coolant flow. Optimized channel guidance and coolant distribution ensure efficient cooling for the engine, transmission, and fuel, enhancing overall performance and longevity.
Innovative Oil Pump Technology for Emission Reduction
Addressing the need to minimize emissions from combustion engines, MAHLE introduces the controlled pendulum-slider oil pump. This innovative pump excels in efficiency and offers smart, demand-based supply of oil pressure and volume. By optimizing oil management components, such as the oil pump, significant reductions in CO2 emissions and fuel consumption can be achieved. Compared to conventional oil pumps, MAHLE's controlled pendulum-slider oil pump has the potential to reduce CO2 emissions by up to two percent in the New European Driving Cycle (NEDC). This technology plays a vital role in improving the environmental performance of passenger cars while enhancing overall engine efficiency.
