Detroit Diesel (DD671N) Questions

Are your 671s turboed or normally aspirated? Naturally aspirated. It's funny when you get to know how the various engines sound. I can identify the sound of those 671s anytime I hear them start up. You and all of my neighbors. :-) It's like having a pair of Greyhound busses idling in your backyard. A friend has a pair of normally aspirated 671s in a 1972 Hat 38 - actually a conversion from original gas engines. They have over close to 10,000 hours on them and run like a top. Great engines. They have a reputation of lasting almost forever and can be totally rebuilt in place with new cylinder sleeves, bearings, pistons, etc. It's my understanding that in commercial generator service they frequently go 20,000 hours between overhauls although 4 or 5,000 hours is more typical for marine service. |
