I had a truck repair facility acquire and install a used 8V71T in my MCI-7 conversion. As I live in CA and they are in GA, the project ran mostly by phone calls. Last month, it was being ferried to me, an injector stuck, creating an engine (and coach) runaway). It turns out the shop never migrated the air shutoff valve from the old engine to their new one, so it ran until it failed. Does anyone know of a NTSB or DOT, etc. requirement for road going vehicles to have these shutoff valves on these, or any diesel engine? |

far as I know,Detroit is the only one that has them,BUT,unless you are REAL alert,and get it snapped REAL quick,they don't work,if you wait a couple seconds too long,it just sucks the seals out of your blower and continues to run away...did they not turn the key off ? |

The driver turned the key off but it just kept on running (and running). The emergency shutoff switch was on the dash and it was turned off too, but later, we found it wasn't connected to anything. |

most industrial equipment...generators. fire pump engines have some sort of shut-down systems...most deck engines.. the 1's halliburton and schlumberger have.... most drilling rig engines have them... "rig savers"...NO marine propulsion engines have shutdown..only alarms...as far as i know DD only used the flap-type shutoffs on 2-strokes, mainly automotive engines 71 and 92 series....every 149 and 53 series in an indusrtial application has them....my 8v71 in my mci9 does not have a shutoff.. but i am planning on installing 1.... |

Jim...maybe you can explain it to me...when you turn the key off,you are shuting the fuel off to a diesel,on a car.you are shuting off elec.to the engine....if the driver shut off the key(the fuel),why did he still have a runaway... |

TWO DOGS 2cycles are konwn to run away cause they run on engine oil from the blower seals which fail. I've seen 4 cycle runaway cause turbo seals failed an it's not nice,big holes an sometimes fire. |

Two Dogs, when an injector on one of these two strokes sticks, it can jam the rack. If it does, the shutoff lever on the governor housing will not shut the fuel off because it can't move the rack.
If fuel (or oil) continues to get into the cylinders, the engine keeps running. That's why the air valve for an emergency shutoff.
If I were confronted with this situation and the engine wouldn't stop, and it was an automatic, I would try to keep it in gear and hold it with the brakes, then have someone get to the air intake grills and throw pillowcases or towels over them.
If it was a stick, I would use the clutch and the highest gear I thought that I could get to and just stall the engine.
Most times, I would think that the rack would be jammed at something less than full rack. If that was the case, a person might have a little time to deal with the problem. Breaking a fuel line or pinching it might be an option, too.
I like having a working air valve, so if that's possible, that's what I will do.
For what it's worth.

Tom is right, in the sence that a stuck rack may not move when the air cylinder for the engine shut-off is activated.
Also, when there is no air pressure at start-up, the air shutoff is ineffectual.
Buddy of mine was working on the rack of an 8-71 when he started it and it ran away on him, fortunately the air intake hoses were off.
He reached over to his tool tray picked up his aluminum clipboard and smacked it over the intake horn, and killed it!
My own coach has an electric emergency solenoid, something I've seen on several 8-71's.
I don't think I've seen an air operated emergency cutoff valve.
Just as the regular air shut-off is ineffectual with no air pressure at start-up so too an emergency air shut-off would be...
Consequently, the engine would be completely unprotected in the event that it ran away at start up with no air pressure.
While it is only a relatively short period of time until the coach has air, the majority of runaways I have seen and heard...thankfully not to me, were at start-up.
If I had an air cylinder on my emergency shut-off, I'd replace it with the heavy duty solenoid type.

The emergency air flap shut down isn't always effective, the best upgrade you can make to your engine is to install the newer spring loaded racks. That way if an injectors sticks you can still shut off the other injectors and shut down the engine. 92's and later models 71's don't have an emergency shut down because they have spring loaded racks.
As far as Robert's problem goes, I think the shop that installed the engine should have transfered and installed the air shut down flap. But they were probably not familiar with 2-stroke Detroits, so they didn't worry about it.

Hello all.
The fuel racks all have return springs.
One of the failures is the breaking of a return spring, which may leave the rack in a fueling position, allowing for a runaway.
Another reason to have reputable establishments do your major repairs. Fresh springs installed during any major engine work greatly reduces the chance for failure. Returning the old springs to duty is folly.
Once we reach the DDEC years, if the injector is electrically commanded, the mechanical parts are not there to fail, hence no need for the emergency shut down.
DDC was rather unique in giving us a way to stop their motors if there was a fuel system failure, or internal breakdown that allowed the engine to inhale its own oil. It is rare to hear of any other engine type being so equipped.
As noted, one of the most popular times for a runaway, is the first start after the mechanic has reassembled the engine....
We must also remember the panic factor in the stories we hear about these horrible occurances. Humans don't make good witnesses when they are freaked, especially if their egos or self worth may be impacted by the outcome.
happy coaching!

The newer rack controls have individual springs on each injector, vrs. the old style with solid adjusters. I believe you are talking about the tube return spring-- both new and old style still have those. |

Wonder if there would be a way to have a CO2 extinguisher piped into the air intake to stop the engine? Set up with an electric solenoid and activation switch on dash and in engine compartment. Any thoughts?Yeah,I know...the factory setup has worked well for millions of years on billions of Detroits...just an idea to discuss. A runaway engine will scare the H out of you and leaves a permanent mark in your memory...let alone underwear! |

Gary: When a DD 2 stroke runs away it accelerates very rapidly until it reaches the point where it flies apart. Unless you are standing beside it when the run away starts, I don't think you would want to be sticking any part of your body close to the engine with a fire extinguisher in your hands. |

I'm familiar with what happens during a runaway.
this is common practice to have a CO2 extinguisher at hand in diesel Enginerooms. Particularly, in the case of a DD, where the airboxes would make it hard to totally block out the air intake with rags, etc.
Please consider the chain of events that would occur if you were offshore and a DD grenaded.
I'll take my chances getting it shutdown.

The best thing to do if a Detroit takes off and the air shutdown doesn't work (I think they will only rev up to 2800 or so: full fuel, no load, no governor) is to pinch off the inlet fuel line with a pair of vicegrips. No vicegrips, break off a fuel fitting. You can try to cover up the air cleaner but that is not usually easy. If you fill your engine up with C02 it sounds like it will need a total rebuild when you get it stopped. |

Sorry, that's not the case.
The problem with DD's, as Two Dogs mentioned, is that the engine will scavenge crankcase oil through the blower seals.
The only thing you can do is to stop the air.
In marine applications, especially in salt water environments, the trapdoors can sieze (one of mine did) and you have no emergency stop.
If you go look around a bunch of workboats powered by DD's you'll find a CO2 bottle in virtually every engine compartment (Mine has two).

But in this instance, he is right, and I think a twin bottle CO2 setup sounds wunderbar.
One bottle for runaways... one bottle for engine bay fire supression.

The company I work for moved out of San Jose, transferring all kinds of stuff to our manufacturing plant in Mexicali. They sent a Forklift down there. When they got to customs and there was still a Propane bottle on the lift, they practically bullwhipped the guy that sent the lift down on the truck.
One day I came in and there were about 30 fire extinguishers. I asked the guy what was going to happen to them and he almost turned white (He's Japanese). He said he was going to throw them in the dumpster. I offered to take them and I thought he was going to kiss me or something.
I also mentioned a few weeks ago that I had a bunch of forklift bottles. You can guess how I got them.
Anyway, about half-a-dozen of the bottles were CO2.
I sure didn't go out and buy them.

The only time I have ever heard of a Detroit running off sucking oil is AFTER it had been running for an extended time from a stuck injector or rack. I have had a few Detroits take off on me, and I was able to shut them down. After all, I have been working on them for 30 years. |

I question if CO2 would hurt an engine or not Geoff, after all, it is just air that won't support combustion, right? I also question if you could get enough of it injected into the intake to stop a runaway, since it would still be sucking in enormous amounts of combustible air along with the CO2. Has anybody ever actually shut down a runaway with a CO2 bottle? Maybe the CO2 bottles Gary are just for engine compartment fires. I don't know much about boats, but it seems you would be in a world of hurt if everything in the boat burned except the engine. (I think that is why Jim bought a tin boat.) |

Hey Don--
I've never had the misfortune of having to do this, but some of my friends have. When you uncork a CO2 bottle A whoppin load of gas comes out. I'm sure enough to choke a DD.
The bottles are for both--Also, CO2 is not messy. That's all I want to do after a fire is to clean up a bunch of Soda in every nook and cranny of my dngine room.
Jim's got a real nice little tin boat. It's the smaller cousin of the two I have.

I am replating my 56'boat, 3/16" steel. Most of the time spent is cutting away the old steel with zip discs.
I think the Plasma cutter will greatly improve my productivity.
Once all the cutaway work is done, welding in the new steel is a snap.
Plasma will make fabrication of replacement pieces quicker too, but not enought to justify the unit.

Bad news is that it is in Topeka Kansas!
I think the day will come Gary that you will think yourself foolish for not going ahead and getting the plasma cutter, that was my first thought of needs when I saw Jims' tin boat. Mine is a 1/2 inch thickness rated one and sure seems adequate to me.

My uncle once stopped a runaway 8V71 (jammed rack) in a GMC Brigadier tractor by emptying a CO2 extinguisher into the airbox. He replaced all injectors, springs, essentially the entire injection system (the boss's exact words were "take absolutely no chances this will happen again"), swapped the blower, & ran it another 300,000 or so miles before the next in-frame. So, in summary, it seems that yes, it will stop it (as long as the bottle is big enough), and no, it shouldn't hurt anything--though a prompt oil & filter change couldn't hurt.
He was never a big Detroit fan (something about having as much oil ON the engine as IN it), but certainly didn't knock their durability. |
