MAHLE Powertrain is the Engineering Services division of MAHLE GmbH. We offer the whole spectrum of engine design and development capabilities starting from initial concepts, through benchmarking and simulation, detailed 1D and 3D analysis and prototyping to engine build, testing, calibration, performance development, package studies and installation into demonstrator vehicles. The key steps in this process are illustrated in this video based on our own in-house design for a state-of-the-art, 4 cylinder downsizing engine. For more information visit: The 1.2-liter unit, a three-cylinder gasoline engine, can appropriately power a mid-class passenger car with a power output per liter of up to 120 kilowatts (163 hp). Compared to typical gasoline engines in this vehicle class, this is a downsizing by half—with up to 30 percent less fuel consumption. The technology demonstrator uses cutting-edge technology: forged pistons, two overhead composite camshafts with double camshaft adjustment, four valves per cylinder, direct injection, air-water charge air cooling, cooled exhaust gas recirculation, and cooled lightweight valves. A further technical highlight is the completely integrated intake module, in which the air filter, charge air cooling, noise suppression, three individual throttle flaps, and introduction of exhaust gas recirculation are accommodated. To consistently minimize fuel consumption, frictional loss was also drastically reduced: with the use of innovative coatings on piston pins, piston rings, and cylinder running surfaces.
