it only took then 3 years and $45,000 of college to figure out that this design wouldn't work.
I on the other hand am a JR. in high school and just but looking at the schematics and the overall layout knew that this wouldnt last very long if they figured out the right adjustments.

So lets use an air compressor (supercharger) instead of the piston to force air into the combustion chamber, and then throw a poppet valve in (replacing the reed valve) to prevent backflow. Congrats on redesigning the wheel, while throwing some more parasitic losses into the mix and letting some more unburnt fuel escape the exhaust port. Result: Heavier, more moving parts, more friction, less efficiency, etc etc. Why not turbo, direct inject, and throw a variable lift hydraulic valve in?

@1sk8trboy1 Keep in mind it was a proof of concept. Of course if something like this was implemented into a production engine, it would use a supercharger. There was much extra complexity built into this unit in order to accurately monitor the inputs and outputs of the system. The real conceptual result was the fact that we could utilize a passively controlled poppet valve - NO CAM! We wanted to direct inject the fuel but with the timeframe and limited budget we had, we had to go carburetor.

I can say this engine may produce more horse power and torque at very low rpm than 4 stroke and may have a rebuild time of a particular 4 stroke engine, it means that it did have greater reliability since it doesn't required lubricant to be mixed with petrol, lubricated in a same way as 4 stroke as its diesel counterpart

I did say that it is possible to develop this engine into multi-fuel engine if added fuel injector, did this things burn lubricant or just using lubricant for lubricating like 4 stroke engine?

Nice job!! I'm sure you're glad to have it all done now, though! Very impressive.
