Imagine the situation. Your car has passed the 500,000 km and your engine is about to say enough is enough after many miles of wear. Consumes a lot of oil, has lost some compression and power no longer is the one that was. Tap to rebuild the engine, but the invoice cannot exceed the cost of the car. Ford has just developed a technology that will allow to return to the life of old engines and use their blocks to give them a new life, faster and more efficient than a reconstruction of a traditional one.
This process of reconditioning of used engines is much more efficient than the cast block and the manufacturing of a new engine.
the idea behind The technology PTWA (Plasma-transferred Wire Arc) is soften the rough edges and uneven surfaces features a engine worn out. The wear and tear of an engine block worn is given in the cavities, where they hosted the pistons, whose surfaces can present irregularities or wear, abnormal… including cracks. This technology covers the inside of the cavities of the engine with a thin layer of metal, transferred by a process derived from the welding. This surface is then polished and machined.
The result is an engine block with the same specifications which the block of the factory, reman with micrometer precision. The difference with respect to a reconstruction process traditional is the speed and efficiency of the process, which manually requires many hours of work, with a high cost. At the moment it is unknown the cost of this process newly developed by Ford, but could return to the life of a simple way to engines that are worn, tired. Your sports or your classic could survive decades easily.
This technology was originally designed for the production of the engine block of the beastly Ford Mustang Shelby GT350, whose 5.2 aspirated V8 develops 526 HP and turns at over 8,000 rpm. Ford reports that this process consumes half of resources recycling and production of a new engine block, which passes through industrial processes heavy processing and casting of metal. If they manage to scale the technology and reduce its cost, it could give a new life to a multitude of cars that were thought to be “homeless”.
