The Mitchell mechanical Variable Valve Timing (VVT) system is described. The way in which it exploits variable angular velocity to change valve timing is explained. The system was used in a programme ...

Every aspect of an engine is a compromise: torque for horsepower, efficiency for emissions, performance for fuel economy, compression for octane tolerance. During the evolution of the internal ...

We’ve just heard that Piaggio Group, parent company to Aprilia, is working on a mechanical variable valve timing (VVT) system – and the first to reap the benefits of the tech will be none other than ...

Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in ...

Variable valve timing isn’t necessarily a new idea, but it is new to BMW motorcycles. With a freshly designed 1,254 cc two-cylinder flat engine, VVT is arriving in BMW bikes for the first time with an ...

Honda did not invent variable valve timing or variable valve lift. In fact, Cadillac had a driver-operated variable valve timing system in production in 1903, three years before Soichiro Honda was ...

The fifth generation of BMW's four-valve boxer engine will make its debut in the new R 1250 GS and RT. The latest evolution of its liquid-cooled boxer features increased capacity, more power and ...

The problem is as old as the internal combustion engine itself: Static valve timing is always a compromise. Figures that produce good power at lower engine speeds aren't ideal for higher-rpm operation ...

Pune, India, Feb. 03, 2022 (GLOBE NEWSWIRE) -- The global Variable Valve Timing (VVT) Market size is expected to reach USD 48.82 billion by 2028 from USD 35.20 billion in 2021, exhibiting a CAGR of ...

Variable Valve Timing isn’t a new concept in motorcycle engines. The likes of BMW and Yamaha have been using this setup in their motorcycles for a while now. Even Suzuki itself implemented it on the ...
