Diesel engine runaway occurs when a diesel engine ingests a hydrocarbon vapor, or flammable vapor, through the air intake system and uses it as an external fuel source. As the engine begins to run off these vapors, the governor will release less diesel fuel until, eventually, the vapors become its only fuel source.

Can a runaway diesel explode?
A runaway diesel engine, depending on the richness of the vapor cloud, can explode within seconds. There is no time to take any corrective action and it is dangerous to approach a runaway engine to try to shut it down.
What happens with a runaway diesel?
Diesel engine runaway occurs when a diesel engine ingests a hydrocarbon vapor, or flammable vapor, through the air intake system and uses it as an external fuel source. As the engine begins to run off these vapors, the governor will release less diesel fuel until, eventually, the vapors become its only fuel source.
How do you stop a diesel runaway?
The operator cannot stop the engine because it is now running on motor oil and will be destroyed by mechanical failure or bearing seizure unless the air intake is blocked or the air is displaced with CO2. The safest method to stop a runaway diesel engine is by directing a CO2 fire extinguisher into the air intake.
Why Do Diesel Engines Runaway? What Is A Diesel Engine Runaway?
Will a fire extinguisher stop a runaway diesel?
The safest method to stop a runaway diesel engine is by directing a CO2 fire extinguisher into the air intake. Just like we learned in the fire academy, take away one part of the fire triangle and the fire will go out.
Can too much oil cause diesel runaway?
A massively overfilled engine oil will harm the engine. Massive overfilling in diesel engines can cause runaway that will ultimately destroy the engine.
What happens if you run a diesel with too much oil?
Diesel engine runaway – the biggest risk of oil overfill Experiencing a feedback loop means that you will not be able to stop your engine until it burns out all of the fuel. Burning all the fuel and oil together will is destroy the engine. Feedback loops most commonly occur in turbocharged engines.
Ask The Expert: What Is Diesel Engine Runaway?
Can diesel engines explode?
The numerous potential ignition sources found on diesel engines could all cause an explosion, but it is possible to manage the risk with explosion protection.
How common is diesel runaway?
Diesel engine runaway is a rare condition affecting diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

What happens if oil level is above Max?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
Can too much engine oil damage a turbo?
If there is too much oil in the pan or if the turbocharger in your car is relatively lower, then oil can get through the seals and begin to blow out. Oil Pressure Too Low– If the oil pressure is too low, it can cause the internal parts of the turbo to wear out such as the seals.
