The Japanese company has filed new patents that reveal the development of a small-displacement two-cylinder engine equipped with a variable valve timing (VVT) system. Let's see what it's about
March 28, 2024
Suzuki is reportedly working on a new two-cylinder engine featuring an innovative and advanced variable valve timing (VVT) system. Variable valve timing technology is now becoming a must to increase performance while limiting consumption and almost all the important brands are adopting it. This system allows engine performance to be optimized based on different driving conditions, improving both efficiency and emissions.

Suzuki's patent filing reveals an ingenious approach to variable valve timing. The use of a single camshaft with three lobes for each cylinder, one for the exhaust valve and two for the intake valves, allows precise regulation of the gas distribution within the engine. A two-part system in the intake valve rocker allows selection of the desired profile based on the dynamic needs of the engine. This sophisticated system was designed specifically for the 248cc twin-cylinder engine used on models such as the GW250 Inazuma, V-Strom 250 and GSX250R. The 298cc version of this engine, produced in collaboration with Chinese partner Haojue, would further expand the potential of this technology. The introduction of variable valve timing in Suzuki engines represents a significant step towards optimizing performance and adhering to increasingly stringent environmental regulations. This innovation could bridge the gap in the Suzuki motorcycle range between small-displacement and medium-displacement models, offering motorcyclists a more complete and efficient range.
