Video: Watch someone blow up a diesel engine, because he can
Catches it all on video, as well as the aftermath
One of the first jobs I ever had was working on diesel engines. The big industrial ones, not those tiny things in cars.
There of course several advantages to having a diesel engine in a say a truck, or in my case, a boat. There are fewer moving parts, and diesel engines are much sturdier than gasoline powerplants. One of the disadvantages, however, is that if not properly taken care of a diesel engine can do something called “run away.” This is a phenomenon that sees the engine speed up and keep going until it blows up.
During my time as a mechanic, we were always taught this could happen, but I never saw it for myself.
Youtuber KT3406E setup a 1970 something GMC truck with a Detroit-Diesel 8-cylinder engine under the hood and stuck the injector racks wide open. The engine lasted eight minutes before the engine failed in spectacular fashion. The Youtuber not only videoed the disaster, but he also produced a video of the teardown, which to an old mechanic such as me, was just as interesting.
