Power Stroke or Powerstroke?
Technically, International’s line of Power Stroke diesel engines is 2 words; “Power Stroke”, not “Powerstroke”. However, the name is commony written “Powerstroke”, most likely because it is easier to type one word than two. It does not make a difference, really, since we are all talking about the same thing. A Power Stroke is a Powerstroke and vica versa.
