Harley-Davidson has filed patents for a brand new v-twin engine with VVT
Harley-Davidson could also be preparing for its future fashions with new expertise. And this time, it is for a brand new v-twin engine which is able to use variable valve timing (VVT), in addition to a modular engine balancer. Latest patent pictures present how that the brand new v-twin engine will likely be completely different from present Harley-Davidson engines, and the way the VVT system works in tandem with the modular balancer. The new v-twin will possible supply greater revs and extra refinement, together with extra efficiency and higher emissions, to satisfy the most recent laws. While Harley-Davidson might have been within the information currently for all of the mistaken causes, the most recent information is proof sufficient that there is greater than a brand new engine brewing for the long run.

The new engine nonetheless makes use of overhead valves, however with pushrods operating on reverse sides of every cylinder. The drawings additionally present air-cooling fins, with uneven contours curving out and in at completely different spots across the cylinder. The engine additionally has an oil cooler on the entrance, one thing which signifies that Harley-Davidson will follow an air/oil-cooled format for the brand new v-twin, in comparison with the DOHC, liquid-cooled engines that are anticipated to debut on new fashions, together with the Harley-Davidson Pan America and the Streetfighter. The new v-twin with the overhead valve system is anticipated to say greater engine speeds than the present Milwaukee-Eight.

Diagrams filed with the patent present the engine stability module the place the crankshaft is linked to a gear (No. 154 within the determine above), which rotates a cam gear (No. 158). The cam gear is linked to a second, smaller toothed gear (No. 170) which rotates a series (No. 178). The chain in flip spins a balancer sprocket which rotates a stability weight (No. 86) across the crankshaft in the wrong way of the crank’s rotation. The VVT unit (No 98) adjusts the timing of the cams, affecting when the consumption and exhaust valves open and shut, in relation to the crankshaft. The concept is not only to optimise energy and torque supply, but additionally to scale back emissions, to satisfy the most recent and probably, future laws. So far, there is no phrase on when the brand new v-twin engine will likely be launched in manufacturing kind, or what fashions it’s going to energy.
