Cost Effective Designing?

"Ford's 1.0-liter, turbocharged, three-cylinder EcoBoost engine" - "is the product of five million development hours logged by more than 200 Ford engineers."

That calculates out to 25,000 hours per engineer.  At 8 hours per day that's 3,125 days or about 10 years.   Is that something to brag about?

The engines in the article are truly impressive. I think the amount of small, high-tech engines has been made possible largely through the use of CAD, extremely rigorous computational tools and motivated engineers. There was an article about a year ago regarding the introduction of a compeltely new engine by one of the manufacturers. The development time of this engine was right around one year from concept to prototype. Now with 3D printing and prototyping, I expect the development time for future engines to be further reduced. Good article. It does seem strange though that an engine that is small enough to fit in an overhead luggage compartment of a commercial aircraft still can't be shoe-horned into an engine compartment of an automobile and leave enough free-air around it to permit a dropped nut, bolt or wrench to actually reach the ground.

I think Bob has pretty much described what's going on in Engines.

CFD allows a computational understanding of the combustion process so you can

try to maximize combustion efficiency and fluid flow through the valves and manifolds

and eliminate dead spaces.

Thermal modeling codes and NASTRAN let you understand the mechanical stresses and heat stress so you can make the engine lighter and work to the forces.

Physics based modeling lets you develope control algorithms for the valve timing

and spark timing, so you can  then program computer controlled lifters and ignition.

You can use less material, get more out of the fuel, maximize power and

minimize pollution.

 

Better alloys let you work in aluminum,  higher strength steels, better temperature

resistance steels. Tighter tolerances in the design and manufacturing process means you can have less leakage in the seals.

 

Cars int he 50s to 70's leaked oil like mad. Now they barely drip after 5 years.


Lets not even get into the benefits of better rubber and soft goods.
