Help us out: Engine Designer Demo - Scenarios

[Killrob]

The second world war has ended, but the cold war has just started. Your company has been assigned the task of designing and building a powerful, compact, and reliable engine for the newest light, 12-tonne APC. Your contractors deem it necessary to cut the engine to about half of the size of the current equivalent tank engine in service, which is a 1100ci / 18.0L V8 pulling a 30-tonne vehicle.

Your boss has been brainwashed by the marketing department, and suddenly it is imperative to have a sports car with more than the "magical" 1000 horsepower in the company's line-up. You pointing out that the car it's being put into weighs so much that not even those 1000 horses would soundly win a drag-race against a single biological original is met by angry stares and a hand pointing to the drawing board.

You lost that bet, and you lost it to someone who is smarter than you would have thought. Too much fuel in your blood made you forget to state "existing production" when you said he would get an engine of his choice for his lawnmower tractor. Also, you never said that the requirements need to be reasonable. Your lead engine designer looks at you in shock, but with a wry smile on his face.

OK. Your boss is an eccentric. He has been designing crazy cars all the time. You remember the last time, when he wanted you to design a pickup. With quad-turbo V16. This time, he wants you to design absolutely sensible compact car... With a race V8 under it's bonnet! Can you make sure, that engine generates enough power, while fitting into small engine bay?

Next year is 2019 and the MX-5 is reaching its 30th year in production, Mazda want the MX-5 to continue to be the best-selling two-seat convertible sports car in history (and reduce the stigma that it is a girls car) and have decided to do something "special" with the new NE model.

That something special is to squeeze/shove/cram/crowbar a x.xL V8 into this great car but the MX-5 is know to be a light and nimble car so it cant be to heavy and needs to have more power than the 167 bhp (125 kW) and 140 ft·lbf (190 N·m) of the old 2005 2L.

Size must be smaller than W/H/L

Weight < A (30%)

Responsiveness D > (10%)
Econ/emissions E < (10%)
