Help us out: Engine Designer Demo - Scenarios

[Vain]

Scenario description:
The year is 1993 and you are an engineer in a large European car company. For marketing purposes the company is planning a new prestige-car that combines uniqueness, desirability and quickness on the racetrack. Therefor the engine will need to be lightweight and powerful, but also easy to handle. You work in the engine design department and your boss has tasked you with the development of the initial design for what will hopefully be the heart and the muscle of the new car.

Limitations:
V8
Naturally aspirated
Premium Unleaded 95
Manufacture year 1997

Specifications:
Power more than x (30%)
Torque at 2500 rpm more than y (25%)
Width smaller than z (20%) (Is the v-angle even adjustable?)
Smoothness better than u (15%)
MTTF larger than v (10%)

Good stuff guys! Keep rolling with the V8 scenarios as they will be useful soon

[Vain]

Description:
The oil crisis has never happened and all peak oil scenarios were unfounded. Gasoline is available everywhere for cheap and so is money. Construct the most powerful engine possible based off a 5 litre V8 without using a turbocharger.

Limitations:
V8
Capacity 5 litre
Naturally aspirated
Manufacture year 2012
Premium Unleaded 95

Specifications:
Power more than x (100%)

(This is perhaps more of an introductory scenario. )

A harder challenge:

Challenge description:
One of your best friends, Oliver Petrolbucks, wants to start his own LeMans Prototype car (LMP2 regulations). He entrusted your company with the delicate task of building the winning engine. First of all you must make sure that it meets the harsh regulations imposed by FIA for this race series, and then you have to go the extra mile to get that small edge that allows him to obtain success.

Limitations:
V8
Manufacture year 2013
Max displacement for N/A: 5000cm
VVT is banned
Titanium conrods are banned
445hp < Power < 455 hp
Noise < y (0%) (it's 110 dB in the official regulations)
Price < z (0%) (it's 75000 euros in the official regulations)

Specifications:
Max weight < x (15%) - (as the car has to weigh 900kg at most, you should make it as light as possible)
Smoothness > u (30%)
Responsiveness > s (30%) - (smoothness and responsiveness are essential for the long races in the LeMans Series )
Torque > v (15%)
Economy > t (10%) - (with a maximum fuel tank capacity of 75l, better fuel economy means less pit-stops, which would be the difference between 1st place and 7th place)

Just downloaded the demo, had a quick play on it.

Why not a small capacity bike engine challange?

Description:
You have been tasked with making a bike engine for the new 47 bhp class, and must be smooth and responsive, with good economy. Due to the way the licence works, you are allow to develop two versions, one with up to 94 bhp, and one with 47 bhp.


Limitations:
47bhp max
other thingies.
2013 onwards for tech level.


It should probably be an easy one - I've got a 397cc to develop 74 bhp.

Now running 83.4 bhp.

The year is 1969. Chevrolet has just released their Camaro muscle car. Dodge has called you up to make a V8 engine for their car called the Challenger.
Specs:
More power than X (45%)
Cheaper than Y (40%)
Lifespan longer than Z (15%)
Limitations:
1970 tech level

[Daffyflyer]

Good stuff! More V8s folks, we'll be needing them soon!

Scenario description:
It's year 2003. An american sports car company has been producing their lightweight coupe powered with I4 engine for 8 years. While they gained customers and escaped the verge of bancrupcy, they feel that their cars lost souls they used to have. They plan to return to making V8 muscle cars, now powerful, high revving yet eco-friendly. Fortunately, they now HAVE enough money for clean slate design. And they have approached you to design the new V8 engine, as they were satisfied with the engine you designed for them back in 1995.

Technical limitations:
Must run on Regular Unleaded
Must be V8
4000-8000cc of capacity
Manufacture year: 2003

Technical specifications:
Total Costs less than x (25%)
Power more than y (30%)
Emissions less than z (10%)
Lifespan more than a (25%)
Loudness less than b (10%)

+1 for this one, a continuation of "spinning faster"

[Vain]

Description:
Your company has been contacted by members of a club of glider pilots. They want to update the winch they use to launch their airplanes from the ground. The winch needs a new sturdy but beefy engine to propel the airplanes as high as possible. The engine must however fit on the same truck they used for the old engine so you'll have to use a naturally aspirated V8 engine. The group is operating on a tight budget thus financial efficiency is very important.

Limitations:
Naturally aspirated V8
Regular unleaded
Manufacture year 1995

Specifications:
Total cost lower than z (35%)
Maintenance cost lower than y (25%)
Power higher than z (25%)
MTTF higher than w (15%)

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.

Year 1947 (Techyear 1945-1949)
6-12L capacity
92 Leaded

power > X (30%)
MTTF > Y (30%)
Econ < Z (30%)
Size < Q (0%)
loudness < W (10%)

[Killrob]

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.

Year 2005 (Techyear 2002-2007)

power > 1000hp (0%)
MTTF > X (30%)
Response > Y (25%)
Smooth > Z (25%)
weight < W (20%)

[Killrob]

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.

Year 1989 (Techyear 1985-1992)
Capacity < 1000cc
Unleaded 95

power > X (10%)
econ < Y (30%)
MTTF > Z (30%)
weight < W (20%)
Smoothness < Q (10%)

[Kubboz]

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?

Year 1982
width < x
height < y
lenght < z
Must use race intake

Power > A (40%)
Lifespan > B (20%)
Weight < C (20%)
Responsiveness > D (20%)

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%)
Power > B (30%)
MTTF > C (20%)
Responsiveness D > (10%)
Econ/emissions E < (10%)
