This effect is called dieseling and occurs when you have a buildup of leaking oil and sludge in the piston chambers. This buildup is red-hot during ignition, and is slow to cool down. While still red-hot after shutdown, it continues to ignite gas fumes being drawn into the engine.
Thus the motor continues to run for a short time.

Why does the fan keep running on a 1983 caprice classic when engine is off?
If the fan keeps running it's because it is electric and wired through a temperature switch not the ignition. Electric Fan running is independent of engine running. When the temperature is high enough to start the fan, it goes on. when the temp drops the fan goes off. Temp does not drop right away when the car is turned off. It can actually rise several degrees when the engine is turned off. The fan running after engine shut off is actually a good thing that may prevent radiator overflow

Check for a main vacuum leak. Do you feel a loss of power at idle? The A/C and defrost (which uses the A/C) require power from the engine. If it can handle the accessories (A/C, Defrost) it will shut off. Also the power steering strains the engine, does it shut off when you turn the wheel all the way? If so check for a vacuum leak. If the engine is idling rough, get it fixed.

84 Mercedes 300D turbo diesel problems with engine it's running after ignition switch is turned off?
Technically, a diesel engine does not need any outside electrical source to keep it running. Injectors are mechanical and keep running until they are forced off, usually by a solenoid. Check the shutoff mechanism to make sure it isn't sticking. This diesel shuts off using vacuum. If your vacuum is low or leaking, the vehicle will not shut off using the key. You have to open the hood and push the SHUT OFF plate near the top of the engine in the fuel linkage. Vacuum leaks are common and will keep the door locks, climate control, and engine shut off from working. The shut off valve, located on the back of the injection pump, can fail. It is vacuum operated and the diaphragm can tear. Vacuum test this valve. If it holds vacuum keep looking for other vacuum leaks, if it leaks replace it.
