From my related question, it seems that an engine suddenly shut off would suffer from dangerous differential cooling from the airflow. This differential cooling would cause the engine to warp.

From my related question, it seems that an engine suddenly shut off would suffer from dangerous differential cooling from the airflow. This differential cooling would cause the engine to warp.
How does the engine handle a huge amount of sudden rain ingestion? To me it seems like the sudden cooling on one side of the engine would cause thermal contraction, causing all sorts of problems.
So we've established that jet engines are good at expanding and contracting due to thermal changes. We've also established that relatively speaking we're actually not talking about a ton of water here, just a few grams per cubic meter of air, which would take a small percent of the engine power to evaporate (
So, we told you how to tell if the chip in your key is bad. Now, how will you identify if the engine immobilizer system has gone bad? Well, go straight to the system and inspect the wiring. There will be visible damage, corrosion, or maybe other wear and tear there. If that is the scenario of your vehicle too, you must know that the immobilizer system has gone wrong. [links]
The result of a lousy key could be the failure of sending proper signals to the immobilizer, hence no adequate car functioning. more
The immobilizer doesn’t let the engine start, in case a proper security token is not provided. You can try starting it, but it won’t start if that is the case. Always check the wiring of the car immobilizer, as there you can find the reason why your engine is not working.
This system, when goes bad, result in malfunctions in different components of the vehicle. It needs an expert’s eye to identify these symptoms and take action to fix it.
Look for a locksmith nearby or get your vehicle towed to some professional to make it work again. more
If you are unable to diagnose the problem yourself, take the vehicle to a mechanic. When your car is jerking while breaking, there are also some specific reasons you may want to investigate.
The vast majority of cars produced after the 1980's use fuel injection engines. These inject fuel into the combustion chamber to mix with air and be ignited by the spark plugs. If the fuel injector in one or more of the cylinders is dirty, it can cause the car to jerk when pressure is placed on the throttle. However, since fuel is continuously being injected into the engine, this is not the only time it might jerk. here
While wear and dirt are common reasons why your car jerks while driving, there are some less common reasons for this occurrence. They include:
The only way of knowing if this is the case is through the use of an Ohm meter. You can purchase them at most mechanic's garages or hardware stores. However, if you are unsure what to look for, it's best you check with a mechanic. They will also be better able to diagnose the problem, in case there is another reason why your car is jerking.
If dirt or grime is the problem, then you may not need to change the spark plugs. Rather, you can clean them to avoid the car jerking. This will likely only be a temporary solution. more
However, if the cable is worn out, then the tension exerted will not be as even. It may even tense, then slacken due to the wear. This is what will lead to the car jerking. Apart from the jerking, there are other signs your accelerator cable may be worn or in some other way faulty: here
It would appear that by the design of this exhaust/cooling system, gravity prevents water from getting in the engine of a properly working/sealed system, running or not.
As long as we are on this topic with the 787 engine, I had some thoughts. I know traditionally the rule has been, never flow water through the system without the engine running, & stop all water flow before stopping the engine. That makes perfect sense, however I just pulled the pipe off my 787 last night & it would appear that the only water that enters the pipe is well below the exhaust manifold, so unless your exhaust gaskets leak at the manifold, it really can't flow up hill & into the engine. Only thing I could see possible is if the water entering the pipe was under pressure, splashes hard enough within the pipe and causes some droplets to go up the pipe & back down the manifold into the ports.

That being said, If you had manifold gasket that was failing between the water jacket & exhaust ports, your engine might become a swimming pool
When the vehicle’s engine is immediately up and running; the automatic shutdown relay kicks-off too, supplying a switched power of 12+ volts to the ignition coil and fuel injectors; this helps to allow the smooth operation of the engine system.
The Automatic Shutdown (ASD) relay controls the power supplied to the fuel injectors, ignition coil, oxygen sensor heater elements, and other parts of the power module. The ASD relay shuts down the fuel ignition and the fuel pressure immediately after the ignition key is turned off; this is done to prevent problems like fire, dieseling, etc. [links]
But you have to know that if the wires are very old, for instance, about 15 years old, I cannot guarantee their efficiency due to the fact that they might be worn out. So it advisable to change the wiring system at this point. here
