Rheinmetall develops low-friction crankcase for diesel engine

Rheinmetall announced that KS HUAYU AluTech GmbH is producing its first all-aluminum four-cylinder diesel engine parts for a passenger car diesel engine series of a major German OEM. This is the transverse version of the engine series that is now in regular production. For the engines developed with a displacement of two liters, die-cast housings are used on the lower-performance models. The manufacturing process for a second more powerful unit is low-pressure die casting. This uses inorganic cores and a special cooling technique to meet the complex geometry of the component as well as mechanical requirements and operating specifications. Production for both started in autumn 2018 and is planned to run until 2027. On both models, the cylinders feature a special lining, applied by the OEM to deliver significant advantages in terms of friction and thus consumption and emissions.
