By Dennis Chung has filed 13 separate patents with the U.S. Patent and Trademark Office related to a motorcycle with a turbocharged engine. The patent illustrations show a parallel-Twin engine resembling the XE7 turbocharged engine Suzuki presented at the 2015 Tokyo Motor Show.
The illustration above shows the engine in a motorcycle that closely resembles the Suzuki Recursion, a turbocharged concept shown at the 2013 Tokyo Motor Show. Though only a faint outline, the motorcycle has a similar fairing and the same trellis license plate holder behind the rear wheel. One big difference is the trellis frame and subframe shown in the patent instead of the Recursion’s twin-spar frame.
Figure 2 shows the engine in the frame with two radiators. Figure 6 shows the engine, with Figure 10 highlighting the components of the forced induction system. The turbocharger (121) is located just below where the header pipes join. The airbox (115) and intercooler (131) form a single unit located above the cylinder heads.
The engine shown in the patents looks very similar to the XE7 engine shown at the 2015 Tokyo Motor Show.
The engine still looks to be a mid-size parallel-Twin. Stacked transmission shafts make for a very short powerplant, and this enables what appears to be a very long swingarm, which would reduce the tendency to wheelie.
A few of the patents describe the engine’s lubrication system, the placement of balancer shafts in front of and below the crankshaft, the twin radiator set-up, and a way to make sure cooling water is supplied to the turbocharger when the motorcycle is parked and leaned …read more
