Toyota Formula One
Luca Marmorini designed the Ducati like (older generation 4 valve system) desmo for the Toyota Formula one racer. Toyota thought of a V10 desmodromic F1 engine for improving the performances of their engines. In that period (somewhere between 2002 and 2009) all the solutions were tested. They built a single cylinder head for testing and compared its performance with a pneumatic return valve solution. The Desmo showed the same power of the pneumatic solution, but better performance in the mid range, demonstrating the superiority of the desmo system. The desmodromic engine didn’t race due to the risk of a so complex mechanical system. The Toyota race car had already so many problems at that time, so introducing an other uncertain variable was regarded to be a too high risk. Beautiful professional pictures show details like forked (positioned closer in line opposite each other) camfollower fingers and DLC-coated cams and rockers. [Classification = Group 5]
