Audi Integrating 4 Cylinder

Audi is integrating their remodeled 4-cylinder engine into 6 and 8 cylinder executive cars. This is a concerted effort to downsize engine size to meet consumer demands for fuel efficient cars.

According to the patent application, Audi’s all-new four-banger is an “internal combustion engine with multi joint crank drive and additional masses on articulated connecting rods for damping free inertia forces.” In this new configuration, the pistons and conrods are offset to one side of the crank and are connected to it through a rocker-style link. In a conventional four-cylinder motor, the conrods and pistons are running in line with the crankshaft.
