BMW N20 Engine For Sale

This engine, introduced in March 2011, is part of the BMW EfficientDynamics program, wanted by the Bavarian company and started a few years earlier in order to build engines and adopt other technical solutions in order to reduce consumption and polluting emissions, while safeguarding the performance of the cars. Among the directives of this program there is obviously also the so-called “downsizing” process, which means replacing the engines in use with others, newer and with a displacementmore contained, but with similar performance and designed to reduce fuel consumption and toxic emissions. This is the context of the birth of the N20 engine, a 2-liter four-cylinder engine supercharged by a twin-scroll turbocharger, that is, with a split duct turbine.
