If the same spot gets hit over and over, seems like it would weaken that part of the cylinder wall or piston top.
As far as burning leaner fuel producing less NOx, well, yes it's true, but I believe you will also have less power produced? So you need more fuel to produce the same horsepower output hence the same NOx totals?
As per the article, the laser(s) can be focused to specific points within
the combustion chamber. So the bulk of their energy would be focused on igniting the air/fuel mixture, not on the cylinder wall.
The scheme also claims to produce a more efficient and complete combustion, therefore producing fewer NOx compounds. More efficient combustion also means a leaner mix can produce equal HP.
