Suzuki files patent for unconventional engine design

Suzuki has filed a patent for what’s a singular means of putting in an engine in a bike. Whereas the concept is a radical one, Suzuki shouldn’t be the primary producer to attempt to, actually, flip the tables on typical engine design and set up. Italian bike constructing agency, Nembo, designed a motorbike known as the 32, which sported an upside-down engine. The primary prototype of this bike was operational means again in 2011. Nonetheless, owing to lack of funding, a production-ready Nembo 32 by no means noticed the sunshine of day.

Nembo experimented with an upside-down structure in an effort to assist mass centralisation – the mass of the rider together with the crankshaft (now positioned on the high of the motor), scale back the radius round which a lot of the mass is distributed. This ends in a motorbike that’s theoretically far more nimble.

In Suzuki’s case, the patent design doesn’t present a totally inverted motor, however one which has been angled ahead and now carries the gearbox within the entrance (underneath the cylinder) somewhat than on the rear of the motor. This design appears relevant to engines with single- or inline cylinder layouts. The advantages of doing so come within the type of a shorter wheelbase whereas making room for an extended swingarm. This, once more, improves the dealing with of a bike.

From the patent picture, it may be seen that the cylinder now runs virtually horizontally, with the cylinder head perpendicular to the highest of the fork. This creates extra space within the entrance, permitting the engineers to maneuver the entrance wheel backwards, ensuing within the shorter wheelbase. The structure additionally permits for the swingarm pivot level to sit down additional forward than on a standard bike, for the reason that crankshaft is now on the upper-half of the bike.

Whereas the design will probably bear a number of modifications earlier than it makes its option to a production-ready mannequin, it raises the query as as to whether will probably be attainable for engines with a number of cylinders. For this specific structure, a bigger engine would require a a lot wider body, which might get in the way in which of steering motion. Nembo had managed to squeeze in an enormous 1,814cc inline three-cylinder motor throughout the 32’s body, however the Italian firm had turned its engine upside-down, whereas the Suzuki design isn’t a whole 180-degree rotation of the motor. Suzuki’s patent picture additionally doesn’t embrace the positions of parts just like the radiator and air filter field.

That mentioned, Suzuki does have the technological and monetary backing to make this design a actuality and will probably be intriguing to see if this ever makes it to a manufacturing bike.
