The engine features chain-driven double-overhead cams, and it is evident that a part is attached to the intake camshaft's sprocket. Although this aspect of the design is not mentioned in the ...

replacing the stock camshafts in single and double overhead cam (SOHC and DOHC) engines is a simpler task than with the centrally-located camshafts in pushrod engines. An engine's camshaft has egg ...

leading to the invention of the 4-valve per cylinder double overhead cam. Past four-valve-per-cylinder engines had issues with their low-end torque being traded for high-end power and vice versa.

engines that are "fuel agnostic," and is a clean-sheet design with a new block. The Octane will lead to future diesel and hydrogen derivatives that share its architecture (double overhead cam with ...

A key design feature of the new platform is a Double-Overhead-Camshaft (DOHC) realizing significant advances in combustion and thermal efficiency. Friction losses across the engine design have ...
