What causes a Detroit Diesel to run away?
What causes a Detroit Diesel to run away?
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.
Why is the series 60 Detroit Diesel engine still running?
In a bid to save fuel, the engineers at Detroit designed the 60 to idle at very low speed. However, it took Detroit about 10 years to realize that the engine’s idle speed was not fast enough to operate the oil pump. As such, many older (pre-1997) engines have had lower engine bearings replaced more than once due to oil starvation.
Why does my Detroit Diesel engine not start?
While the 4-gauge wires the engine came with were sufficient from the factory, time can reduce the cable’s ability to transfer current to the starter. This lack of power leads to a no-start condition that closely mimics a dying battery, and can be recognized by battery cables that run much warmer while starting the truck than they should.

What causes a diesel engine to run out of fuel?
Oil supply into the intake. This creates an excess oil mist, which is then drawn from the crankcase into the air intake via the breather. A diesel engine will readily burn this oil mist as fuel, since engine oil has similar energy content and combustion properties as diesel fuel. The extra fuel causes the engine revolutions to increase,…
