In a direct injection diesel, like what's been sold for at least the last 20 years the fuel burns as soon as it leaves the tip of the injector. There is no point during operation that the fuel should come anywhere near the cylinder wall.
On a direct injection diesel the fuel injects effectively at tip dead center and it injects into a pocket in a piston.
Gasoline hydrogen mixtures in a gasoline engine has already been tested.
It was already testes in this peer reviewed paper.
It took a lot of hydrogen to give even a 3% fuel economy increase. A $100 bottle of hydrogen would last about 4 hours, assuming you owned that bottle and we're just having it filled for $100.
