Oil management for commercial vehicles

Reliable lubrication is essential for preventing damage to the vehicle. Lubricant flows also cool components that the coolant cannot reach and flush away dirt particles. This is why a reliable oil management system is so critical.

Systems for oil management

Oil filter modules

The development and production of complex oil filter modules has long been one of MAHLE’s core competences. When the overall system of “engine lubrication and cooling” is considered, many other functions can be integrated along with the filtration and cooling of the lubricating oil. These include oil mist separation, sensors for pressure and temperature control, oil pressure and crankcase pressure regulation, and the optional incorporation of a fuel cooler. Thanks to the integration and use of state-of-the-art materials—especially of high-performance plastics—, significant cost and weight savings can be achieved. Completely incinerable ecological filter elements that are easy to replace and dispose of are seeing increased use. Long-term filter elements using modern filter media and manufacturing processes provide an essential contribution to the extension of service intervals.

Oil heating and cooling systems

Current MAHLE heating and cooling modules are able to also handle channel guidance, temperature regulation, and filtering of the coolant flow. An optimized channel guidance and distribution of the coolant flow provides coolant to the heat exchangers of the engine and transmission as well as for fuel as needed.

One innovation in oil management is the controlled pendulum-slider oil pump from MAHLE. Its high efficiency and smart, demand-based supply of oil pressure and volume offer great potential in terms of reducing CO2 emissions and fuel consumption. The use of the controlled pendulum-slider oil pump translates to a potential CO2 reduction in the New European Driving Cycle (NEDC) of up to two percent compared with a conventional oil pump.
