so, 135 BHP for a 250lb 13b or 40 hp, for a 125 lbs in a ..dual piston-single asplodo thingy. doesn't seem much of an improvement.. over an engine that has been around for 4 decades.
Or 127hp from a 175lb engine (late '90s R1), no rotors needed.
It's all about packaging. You can't fit a normal engine below the rear seat. That said, I'm not holding my breath for this design. It's interesting, though.
It's also an engine + generator in a single package. Keep that in mind when discussing the weight.
Directly comparing the HP or HP/LB between this engine concept and a traditional automotive use engine, is ignorant at best. Specifically note that this engine is being used as a generator. Generators use torque biased engines because they run a high duty cycle and focus on fuel consumption at load. Which is pretty much the exact opposite goals of the automotive engines being referenced.
I'm not sure what's different between this and other opposed piston linear generator ideas I've seen thrown around in the past, but the idea certainly does have some potential.
