Massive Yet Tiny

hey you sound unamerican . leave here

Can you imagine how much this guy has invested in this display? Maybe he should have just built a one piston working model?? This thing would simply melt because it cannot dissipate the heat it generates.

maybe it can

if the pistion moves easy less heat is needed to move it (break inertia) . my diesel never gets hot hell all i haul is dog and sack of groceries. now under load it might but i say with agood squirel cage around it no problem for years i couldnt understand why the 1/2" dia. cox airplane motor didnt melt away , same heat tranfer
----to power weight ratio aplies here..

The heat is not from friction but burning fuel. Engines are kept cool by transfer of heat to oil and other to water jacket. The third is to run a richer fuel mixture, thats how the cox motor kept cool, (also type of fuel). Did you ever feel the heat coming off a car in the summer. That same amount for the horsepower would have to coming out of this motor, somehow. It might be able to produce high HP for short periods but would melt down quickly. PS this design has been around a long time.

@Texmurphy51 how come my diesel
in my small tractor doesnt overheat
it has iron block runs slow . and a 18"sq radiator , well it will break 160 deg if i mow plow hard and work it but thats all
i still say he has found a better way to use soybean oil. i agree since he is doing the work of a 850 cu , his (at temp)
operating frictionwill need to be the inverse mathmatically of the 475 cummins to prefome as he says.
If the alloys are there who cares if it runs
at 350 deg. .

It radiates its heat from the block and the small radiator. Your not making 300hp with it either. Ideally the best efficiency would be to run a hot block , insulation around the block, no radiator only heat comes out the exhaust but no materials or lubricans can take that. If the heat is not dissipated the pistons will melt and thats what it boils down to.

@Texmurphy51 may not 300 hp .but the
torque one would think would be high
due to themechanical advantantage.
If this machine will withstand 70 comp
under full heat load it will sell.
gotta be tough alloy,

You know that there have been losts of similar engines to this starting in the 50s. Otto Lutz built one in WWII Germany. Rotoblock looks the same as MYT and Roundengine is a lot simpler and might actually work.

Rather exess energy.
