I'm not sure a faster burn equates to greater pressure, but perhaps the pressure builds faster (explosion vs rapid burn)? Afterall, diesel has more energy density, so that would imply it generates more pressure, right?
Common-rail diesel engines inject a small amount of fuel just prior to main injection, and this results in a quieter engine. Perhaps something similar can be done with gasoline that would more gradually load the pistons, rods, etc, and reduce the violent forces they encounter.
