Perché i Vecchi Motori di Camion Rinascevano all'Infinito — e Oggi Non Più

Why Old Truck Engines Were Reborn Endlessly—and Not Anymore There was a time when a truck engine didn't die: you opened it up, replaced the liners, and it was new again. Dozens of times. Today, that gesture is nearly impossible—and it's not a technical issue, it's a choice. The secret was the replaceable wet liners: the piston never worked on the cast iron of the block, but on a liner that could be removed and replaced. An Iveco 8060 clocked up a million kilometers and, with rings and bushings, was as good as new. Then something changed in the way engines were designed—and the difference between "rebuildable forever" and "to be thrown away" lies in a detail that almost no one knows. With the Euro 7 regulation for heavy-duty vehicles looming, the question becomes even more uncomfortable: are we losing the longest-lasting engines ever built? At Logica Diesel, we delve into the details where others stop. Write in the comments the most mileage-producing engine you've ever seen.
