Renault Trucks | Engine Parts Produced Additively
Renault Trucks has produced the prototype of a four-cylinder engine using an additive manufacturing process. The company used metal 3-D printing to build the DTI5 engine. The design engineers actually leveraged the additive manufacturing process to produce the rocker arms and camshaft bearing caps, which were then subject to 600 h on the test bench. The company achieved a weight saving of 120 kg for the four-cylinder engine, equating to 25 % of its original mass. In addition, the process saved 200 parts – also reducing the weight by a quarter. Renault intends to use the new manufacturing process to build lighter and more compact engines. According to Renault Trucks, it could be used in the near future for highly specific applications or for small runs. Following the tests, the company's engineers will continue to refine this manufacturing process to further enhance component performance and functionality.
