FCA combines turbo & cylinder head into one piece; files patent

Like many other patent filings, it remains to be seen if the new turbocharging assembly actually makes it into production.

According to media reports, FCA has filed for a patent with the United States Patent & Trademark Office (USPTO) which showcases the turbocharger and the cylinder head combined into a single piece.

FCA’s idea is that with the turbocharger cast as part of the cylinder head, the company would save on the material used to make components such as the manifold, bolts, studs and gaskets. Also, combining the turbocharger and the cylinder head would also make the entire assembly more simple as it could effectively delete the exhaust manifold and the additional oil lines.

Reports state that the design integrates the cylinder head with both the compressor and turbine housing of the turbo, while a cartridge would add the wheels and shaft at a later stage. The patent design includes an internal oil channel for the turbo and a single heat shield for the entire turbocharger and wastegate assembly. An Oldham coupling would control the wastegate operation, which will be complemented by a wear washer to improve its longevity.

While the exact details of the turbocharger-cylinder head combination are scarce, doing away with many of the gaskets and seals could potentially improve the part’s life.

Having said that, like many other patent filings, it remains to be seen if the new turbocharging assembly actually makes it into production.
