The diesel engine is limited by mean piston speed since there is only a specific time frame when the valves are closed and the right crank angle degree is available for fuel injection once the combustion chamber has been filled. So the limiting factor is the injection event itself. Top mean piston speed is around 13-15 meters per second or 5,000 or so rpms.
However, a gasoline engine already has the fuel in the combustion chamber so can reach much higher piston speeds over 22 meters per second and 18,000 rpms.
Which one do you think wears out first......?
