Latest Patents

One of Nakayama's latest patents is an innovative exhaust system for a saddle-ride type vehicle. This system provides sufficient volume in a chamber while avoiding interference with other parts. It effectively lowers the vehicle's center of gravity and reduces differences in exhaust pipe length. The exhaust pipes are connected to the combustion chambers of the front and rear cylinder banks of a V-type engine. Additionally, a chamber is connected to the exhaust pipes, with mufflers linked to the chamber. The design includes an exhaust pipe connection wall and opposing muffler connection walls, ensuring optimal performance.

Another significant patent involves a balancer shaft arrangement for an engine. This design features a balancer shaft supported at both ends by bearings within the engine crankcase. The balancer shaft runs parallel to the crankshaft and includes balancer weights at its ends. Notably, at least one of the balancer weights consists of first and second weight portions, which are positioned on opposite sides of the corresponding bearing. This arrangement reduces the bending moment on the shaft, allowing for a smaller diameter and consequently a more compact crankcase.
