Help us out: Engine Designer Demo - Scenarios

[porph]

Scenario:

It's 1965, your company has been approached by a new, upstart Formula 1 team. They want you to design a 1.5 Liter Inline 4 cylinder engine to go in their new race car. Performance is the #1 priority, for budgetary reasons the engine must be able to run two races within it's useful lifespan.

Technical limitations:

Must be 1.5L, running on appropriate racing fuel, must use lightest materials possible. Anything else, appropriate for the 1965 period, goes.

Technical Specifications:

Must make no less than x HP (40%)
Must attain y MTTF (5%)
Minimum responsiveness of z (25%)
Must weigh less than a (30%)

This is a really good one!

[Killrob]

That scenario is in basically, look at my second post in this thread different year but almost the same otherwise. It's fun! So good idea indeed

[Q_res]

Well, crap, that's what I get for replying a day after reading the thread. In my defense, whilst they are very similar the technical base and specifications would be more challenging. Think of my suggestion as the 'Hard' difficulty level version.

Better yet, I'll tweak it a bit...

Scenario:

It's 1967, your company has been approached by a new, upstart Formula 1 team. They want you to design a 3.0 Liter Inline 4 cylinder engine to go in their new race car. Performance is the #1 priority, for budgetary reasons the engine must be able to run two races within it's useful lifespan.

Technical limitations:

Must be 3.0L, running on appropriate racing fuel, must use lightest materials possible. Anything else, appropriate for the 1967 period, goes.

Technical Specifications:

Must make no less than x HP (40%)
Must attain y MTTF (5%)
Minimum responsiveness of z (25%)

People should probably start pondering V8 scenarios. It's probably a few months off, but we will need some!

[Q_res]

Scenario:

It's 1996, your companies legendary OHV small-block V8 can no longer meet emissions or fuel economy standards. You have been tasked with creating its replacement for use in trucks . You have to live up to the reputation of the legend.

Technical limitations :
Must be a V8 with displacement of 5.0L - 6.0L, Cast-Iron block, internals are open so long as you keep costs low, must be long-lasting, and have good low-rpm torque, OHC can be used but no VVT or VVL

Technical Specifications :
Minimum MTTF of X (40%)
Must make at least Y torque (35%)
Must cost less than Z (25%)

Scenario:
It is 1998 and your company is looking to replace its luxury sedan's current engine, a 3.0L forced induction I6, with an N/A V8 in order to eliminate lag and stress the engine less, thus increasing smoothness and reliability - both vital to your comfortable riding, easy driving, dependable image.

Technical Limitations:
Internals are open, but the block and head are all aluminum so as to avoid major weight increases and thus create vehicle imbalances. Fuel is restricted to Premium Unleaded. Must be reliable, smooth, and relatively light-weight. It should also not be remarkably less fuel-efficient than the engine it replaces.

Technical Specifications:
Minimum Smoothness of X (40%)
Minimum MTTF of Y (30%)
Maximum Weight of Z (20%)
Minimum Economy of A (10%)
