Why hasn't anyone tried to make a 2 stroke gas job using diesel style techniques? Gas direct-injection is starting to become a thing now and that was really the only difference between gas 2-stroke and Diesel 2 stroke, how the fuel and Air get in and out of the cylinder. Of course this wouldn't make sense from an economical standpoint for shit boxes, but having double the power output for performance Vehicles especially with smaller engines certainly would be more appealing than having to boost them to the Moon or have cylinders that can displace more air than the size of the fuel tank.

You wouldn't need a cone exhaust with a diesel style 2 stroke because it doesn't rely on backpressure to keep thr charge in the cylinder. Each one would sound exactly like a 4 stroke except like the rpm is 2x higher. Listen to a 2 stroke diesel; at 3 grand it sounds like it's screaming at 6k

Yeah actually I love when the cement guys come around because they use those 2-stroke Detroit Diesels that sound like sex even at half mast. Sounds way different from a 4-stroke.
I presume there's more work to be done with emissions and regulations and public perception and supply chain and everything else before it would be viable for mas market cars.

They have realy bad emissions because the oilfilm is always ripped apart on the intake ports.

That's... no.
It's their nature to push a little more fuel/air mixture out the exhaust than a 4-stroke. More unburned hydrocarbons in the exhaust. That's why resonant exhausts are a thing on loop scavenged 2-stroke gas engines.
