Exploring an Engine Factory: From Raw Materials to Finished Engines

The presenter visits the HORSE engine factory in Valladolid, Spain, for the first time, explaining HORSE's significance and its joint venture between Renault and Geely.

The tour begins with a look at how 3D printing is used to create spare parts, followed by an explanation of the pressure casting process of aluminum cylinder blocks.

Details on the machining process, including the innovative bore spray coating technique that eliminates the need for traditional friction lines, ensuring better lubrication.

The process includes high-pressure cleaning to remove excess material, and honing machines that create a mirror finish for internal engine components.

The assembly of engine components is described, including an explanation of quality control measures like the helium leak test to ensure precision.

The final stage includes engine testing on a dyno to validate performance. Reflection on the experience and the complexity and precision involved in engine manufacturing.
