Hope those pistons stay lined up as the gears wear...

its a scam trying to lure some investors. it would never work. 5 years r&d and they don't even show a working prototype, because it would not work.

i'm no mechanic but i understand the basics of engine operation,the first thoughts that popped into my mind were-

how does the fuel get into the chamber?
wouldn't the incoming air and exhaust gases be all mixed together?

...my thoughts exactly...on both counts.

The only viable new diesel engine (which is actually very old technology) is the ecomotors opposed piston diesel.

What about aligning the pistons with the cylinders at 1000 rpm of higher?
