Within the quarter century for the reason that launch of the primary Toyota Prius hybrid vehicles have turn into commonplace, however the identical mixture of combustion engine and electrical energy has but to make an influence on two wheels. There have been makes an attempt at hybrid bikes previously and Kawasaki’s upcoming 2024 Ninja hybrid guarantees to up the ante additional, however a number of new patent purposes from Honda present a way more complicated and superior tackle the thought.
Honda has a repute for taking the troublesome route in the case of creating new concepts. That is, in spite of everything, the identical firm that developed oval pistons with twin con-rods and eight valves per cylinder when race rules mentioned it couldn’t use a V-8. So whereas it’s “comparatively” easy to easily bolt an electrical motor to an present combustion engine and transmission to create a hybrid bike—as Piaggio did again in 2008 to create the MP3 plug-in hybrid—Honda is taking a really completely different path.
Kawasaki’s upcoming Ninja HEV hybrid, due in manufacturing in 2024, already guarantees a number of using modes. It might probably work in electric-only mode in cities, as a gas-powered bike whereas cruising, and with each energy items working collectively if you want most efficiency. It’s additionally received a push-button-operated, semi-auto transmission to assist create a seamless transition between energy sources. Intelligent stuff, however not a patch on what Honda seems to be planning.
The brand new Honda patents present varied layouts for a hybrid that mixes a combustion engine with not one however two electrical motor/generator items, together with a planetary gearbox and a multi-ratio guide transmission. The designs present the outlines of two doable combustion engines: one which seems just like the 750cc twin used within the X-ADV and NC750 vary, the opposite a smaller unit, probably a single. Additionally they illustrate quite a lot of doable layouts for the positions of the 2 electrical motors, however whichever model is chosen the fundamentals of the operation would be the similar.

Honda connects the 2 electrical motors and the combustion engine collectively through an epicyclic or “planetary” gearset in a format that’s similar to the transmission that was the killer characteristic of the Prius when it was launched 1 / 4 of a century in the past. There’s no clutch between the engine and transmission, however the planetary gears means the bike could be ridden in pure electrical mode with the engine stopped or in pure ICE mode, and in quite a lot of methods in between.
The primary electrical motor/generator, labeled MG1 within the drawings, is linked to the ring gear of the planetary gearset. The second motor/generator, labeled MG2, is linked to the solar gear within the center, and likewise instantly linked to the discount gearset that drives the entrance sprocket, so it at all times turns when the rear wheel is transferring, appearing both as a generator to replenish the batteries or as a motor to drive the wheel. The combustion engine drives the planet provider that holds the planetary gears in place between.
By itself, the system creates a repeatedly variable transmission—the combustion engine can preserve its most effective pace and the transmission’s output pace is altered by adjusting the pace of the principle motor/generator (MG1). On this state, known as “eCVT” mode, MG1 is appearing as a generator and MG2 and the combustion engine are working collectively to drive the rear wheel.

In Honda’s patents, the system is proven in varied layouts, all inside the silhouette of an X-ADV 750. The layouts additionally present how the batteries could possibly be organized, however don’t learn an excessive amount of into the usage of the X-ADV’s form. If this design reaches manufacturing, it is going to be in a motorcycle that’s purpose-made to deal with it. Given the possible bulk and complexity of the setup, it’s extra more likely to be suited to a tourer, offering an extended vary and loads of energy from {a partially} electrified design, than a smaller, sportier bike. It’s additionally nonetheless clearly a venture that’s a good distance from manufacturing, but when Honda is to hit its self-imposed goal of creating its bike enterprise carbon-neutral by 2040, it’s the form of machine the corporate must be making.
