The "stale air" problem just as much impacts on non supercharged diesels as it does with non-supercharged gasoline engines. And ofcourse the same solution can be had with gasoline engines.
I know you can turbo/supercharge a gas motor, I'm pushing the Turbo diesel. Which a turbo is pretty much a requirement if you want it to run efficiantly. Look at all the older diesel vehicles, (at least in the U.S.), I wouldn't want to drive one either. Audi has been pounding the 24 hr Le Mans the last few years with a diesel engine mainly on not having to stop for fuel as frequently.
