Can an engine run without a spark plug?

There are experimental gasoline engines which are ignited by compression. (Homogeneous charge compression ignition ). But no your ordinary engine needs spark plugs to ignite. Bigger gas or petrol engine use sparkplugs but small engines used in model planes/trains or boats can run without a spark.

What does it sound like when a spark plug goes out?

How the Spark Plug Works Fire requires three components: oxygen (O2), fuel, and heat. In your engine, every time a cylinder pulls an intake stroke, it pulls in air (≈21% O2). Port-injection engines inject fuel during the intake stroke, while direct-injection engines, gasoline or diesel, might wait until the compression stroke.
