Mann+Hummel Automotive Inc. has begun producing what it says is the industry's first composite oil filter module for a European auto maker.
Europe is migrating away from screw-on aluminum canister oil filters, which have been the norm for decades, replacing them with a module that bolts on to the engine and incorporates other components, such as the oil-pressure sensor.
The modular approach allows the filter to be a simple, metal-free paper cartridge easily removed for replacement. Optimally, the engine is designed to allow the filter to stand upright, so the oil can drain out for easy recycling.
Conventional filters can hold more than 7 oz. (0.2 L) of waste oil as they are carted off to landfills, says Thomas Petschl, business development manager. Paper filters removed from Mann-Hummel's latest oil module will hold about one-tenth of an ounce (.003 L) of waste oil, he says. The 5.4L supercharged V-8 for Ford Motor Co.'s upcoming GT supercar will be fitted with a metal-free filter element from the company.
Mann+Hummel had used aluminum for the housing of bolt-on oil modules. The new system will be plastic, providing a 20% weight savings. And it will integrate crankcase ventilation, oil cooler, oil pressure sensor and pressure regulator valve. Individually, those items required 11 screws to attach them to the engine.
