stopping a Diesel engine.
Quote: I remember seeing a similar solenoid on a p22 last year which was very efficient, it stopped the engine dead in seconds, in fact, so quickly we removed it because we thought it may damage the engine !
This is the most efficient way of stopping a diesel as you have no electrics to instantly kill it..
I used to drive buses for a living & occasionally you would get a 'runaway' engine. This is where the engine gets too hot & the the diesel then ignites in the head causing a loop that causes the engine to run flat out!!!!
You may have seen a bus do this !
Into neutral, slam the brakes on, handbrake on, engine now screaming on the limiter, get out & turn the fuel off & wait for it to die. Then wait for the engine to cool down with the engine flap up (about 1/2hour). Then try again!
Makes an exciting day!
An air flap will do the job QUICKER & damage is less likely to occur.
