Perché il Motore di un Camion Dura 1.500.000 km e Quello dell'Auto No

Why a Truck Engine Lasts 1,500,000 Miles While a Car's Doesn't Your car's engine starts having serious problems around 250,000 miles. A diesel truck engine easily gets to 1.5 million before a major overhaul—six times as many. It's not magic, it's design. The difference comes from three things. It revs slowly: a heavy diesel engine operates at around 1,300–1,600 rpm compared to a car's 2,500–3,500 rpm, so for the same mileage, it consumes much less fuel. It starts rarely: cold starts are the time of maximum wear, and a truck might start once or twice a day while your car does dozens. And it's built big: thicker block, enormous crankshaft, tolerances designed to withstand pressures a gasoline engine never experiences. Same job, different philosophy.
