Cooling to be biggest challenge in 2014
Caterham technical director Mark Smith says the biggest single challenge with the 2014 power units will be cooling the engine.
Next year sees a major change in engine regulations with the switch to 1.6-litre V6 turbo units with a large Energy Recovery System (ERS) which can generate power from waste heat from the turbocharger as well as under braking.
Speaking to the official Formula One website, Smith said that the physical changes would have a major effect when it comes to installing the engines, but that cooling would be causing the biggest headaches.
"Bigger than all of that is the cooling challenge," Smith said. "That's probably the thing that, I imagine, has most people up and down the pit lane scratching their heads. It's reasonably easy to come up with a solution that will cool, but to come up with a solution that will cool and give you the optimum aerodynamic performance is the challenge.
"The charged air cooler, for cooling the air from the turbo before it goes into the engine, will, on all of the installations, be quite significant. Physically, the size of the thing will dictate the packaging of everybody's cooling systems. That's the biggest single thing, I think, that's presented itself as a challenge in terms of the overall car architecture."
