Can combustor on piston engine?

  1. Jul 10, 2011 #1
    I found this engine amoung the many on the web from inventors out there. Essentially this person adapted a can combustor onto an inline cylinder engine with turbos. Below I pasted the description from the site. What are your thoughts on this one?

    Description:
    This is a 2 stroke inline cylinder internal combustion engine. The combustion takes place in the intake runner as opposed to the cylinder like that in a traditional ICE. A wall of high pressure air generated by the turbos and enhanced by the counter-rotating radial and axial swirl vanes force the combustion gases in the direction of the piston. Thus forcing it down which exposes the exhaust ports in the cylinder walls where the exhaust gases exit into the turbos. Note there are no obstructions such as valves in the way of either the intake or exhaust track. This engine can produce flow numbers OHV engines can never achieve. The ring package on the piston is below the exhaust ports which minimizes oil loss and harmful emissions common in 2 strokes. At no point do the rings pass over the exhaust port. Since the combustion takes place in the intake runner there is no concern of leakage of the raw fuel into the exhaust port. The piston is not used to draw in the fuel/air charge but serves as a valve sealing off the exhaust port. This engine performs the exhaust and intake step at the same time. Which is when the piston is at BDC to TDC. The compression and combustion take place simultaneously as well which is when the piston is TDC through BDC. This makes the engine far more powerful and efficient than a 4 stroke engine common in most automobile.

    First, that's a horrible animation. It jumps frame to frame so quickly I can't follow the flow path.
    Second, the basic premise just sounds implausible to me. Would not the pressure up-stream of combustion (the "wall of high pressure air generated by the turbos and enhanced by the counter-rotating radial and axial swirl vanes") have to be greater than the combustion pressure?

    Also: "The ring package on the piston is below the exhaust ports." If so, then what contains the pressure for moving the piston?
