Lenawee Co Michigan | This is Canadian National locomotive number 2699. It is a 212 ton, 6 axle machine powered by a 4400 hp V16 4 stroke Diesel.
The engine & train were passing the town of Independence, Louisiana when she threw a piston.

Northeast Arkansas | Oh crap! Bet them people didnt know what hit them! |

Princeton, In | Wow ! When you said threw a piston, you meant it REALLY THREW a piston !! |

| It's hard to tell the approximate size of that piston from the pictures. I was thinking it looked like the size of a 5 gal bucket. Now I'm thinking it looks like the complete piston might be closer to the dimensions of a 15 gallon drum and probably weighs 100 lbs. Looks like only about half of the piston made it to be embedded in the wall.

streator illinois | how far did it go from the tracks to the house |

south central IOWA | Is that the same engine John Deere puts in some of it's tractors? |
|

|
Lenawee Co Michigan | Dunno. The pitchers came in a email.
At 4400 hp, the 16 pistons would have to put out 275 hp each. On a 4 stroke Diesel that would be about (guessing) 600 in³ displacement per cylinder. |

Lapel, In | GEVO
Bore - 9.8 Inches
Stroke - 12.6 Inches
Max RPM - 1050
Compression Ratio - 17.5:1
Turbo - 7S1712
Source - ES44AC operators manual.
Someone earlier mentioned something about the it using the same turbo as other GE locomotives, this however isn't true, the 7FDL16 found in the Dash 8's an Dash 9 uses the 1716 turbo. The HDL's used a pair of the 1408 turbo.
7FDL16 (as found in the AC4400CW)
Bore - 9 inches
Stroke - 10.5 Inches
Max RPM - 1050
Compression Ratio - 12.7-1
Turbo - 7S1716
7HDL16 (as found in the AC6000CW)
Bore - 9.85 Inch
Stroke - 12.61 Inch
Max RPM - 1050
Compression Ratio - 15.2:1
Turbo - (2) 7S1408D
The HDL was NOT a Copper Bessemer design, the HDL was derived from the Duetz MWM632 which was a large stationary spark ignited natural gas/LNG powered engine. GE/Duetz made significant changes to design to make it diesel/suitable for rail. The failure on Duetz's part to meet reliability standards and deadlines resulted in a large lawsuit by GE against Duetz (which they later won).
The GEVO is derived from the HDL, but share little in common with it.
The FDL shares nothing in common with the GEVO/HDL
Doesn't sound big enough to me.bob

Lenawee Co Michigan | Now cut that out  |

Burlington, KS | Thanks, I have to take cylinder pressure traces and vibrations on a couple 8600 BHP V14's in the next couple weeks. I connect to the Kiene valve coming off the head and get pressure traces timed to crank position, as well as vibration traces to tell the timing of valve movement and fuel injection, leading to knowing the overall health of the engine. That requires pretty intimate contact with the running engine, I don't wish for it to embrace me back. Always was concerned of the rapid intrusion of engine parts in the people space, that was impressive. |

NEMO | Wow!!! Now that would be a freak accident!! |

NW PA | 7FDL16 engine. Piston more like a 3-gallon bucket (not 15 gallon!). Power assembly came off because service shop forgot to torque the hold-down bolts. These pictures have been around for awhile. |

Ohio | Justin -I don't believe your explanation blaming a worker for this failure. I think some one got an award for slashing the rebuild costs in the maintenance department. That same person has been trying to decipher the Chinese warranty papers that came with his applauded purchase. |

|
| NOW, that right there was just outright FUNNY!!!!!!!!!! ROTFLMAOOOOOOO!!!!!!!! |
|
| |
|
Texas/New Mexico Stateline | Aluminum or steel piston?
|
|
| |
|
NW PA | I'm stating facts.
Look at the second picture. That is the power assembly, which is the cylinder head and liner combined. The power assembly came off because the hold-down bolts broke. Once the head/liner comes out, the piston has no guidance, beats around inside the engine until it flies off the connecting rod and then goes thru the guy's roof and he's lucky he wasn't killed.
There are thousands of these engines running and power assemblies don't just fly off because someone put a Chinese part in it. While I agree there are way too many Chinese parts in ALL engines these days, in this case the simple fact is the hold down bolts broke because they were left loose.

Ohio | I believe your analogy Justin , just my attempt of a little sarcastic humor. |

Cleveland, MS. Own small farm near Booneville, MS | Haven't read all the posts so I don't know all that has been said. I used to haul the cylinders for the GE locomotives out of Golden Casting in Columbus, IN to the GE plant in Erie, PA. The cylinders were cast individually rather than in a solid engine block. They put four cylinders on a pallet and about 20 pallets was a FULL load for a semi. I never did measure the bore and stroke on one of those things, but the cylinders were approximately 2 feet tall and the bore was at least 9 or 10 inches. Using six of those things for an engine in a semi would have put the steer axle overweight. |

| Although, the incident was happened almost 4 years ago, but reading this thread totally blank my mind. A train threw a piston. Just curious, what was its velocity! If it hit a man then i cannot imagine what would happen! I normally use multimeter to check my car electric problem which I already get some explanation here https://bestmultimeterreviews.org/ .But, what is the procedure to check train problem like this? Although, I have found some other explanation in theeffectiveguide.com but those are not enough. After a few hour research, I have found some accurate answer why engine piston blown. Causes of broken rings, Mechanical damage, Broken Oil control ring and Broken Compression Rings. These are the main reason why automotive engine piston fails or blown. Although, we cannot control mechanical failure like this, but we should minimize this kind problem. Because it could lead big accident.
