That's like asking, "what's the difference between the f22 and its sales brochure?" Not trying to be mean, but I don't understand the comparison. They are wholly different in nature.
Engineering takes a desired outcome in the physical or virtual world and, using principals of math(computer science), physics and chemistry, reduced to reliable functional mechanisms aggregated in a logical fashion, constructs a device that produces on demand the desired outcome.
Marketing, on the other hand, takes a desired outcome in sales and, using the powers of persuasion, produces the desired outcome of greater sales ( I suppose).
