Optimal intercooler layout arrangement for Formula 1 racing engines

This paper demonstrates that efficiency and torque output of the actual Formula 1 power units depends mostly on the turbocharger (TC) efficiency. Compressor and turbine off-design efficiency and turbine energy recovery capability should be maximized to maximize the torque to fuel ratio. Since larger TCs increase turbolag, a new layout for the intercooler is proposed in this paper. This solution reduces turbolag and make it possible to focus on the TC efficiency as a thermal machine. In fact, not only the TC design choices can radically alter the efficiency of the TC itself, but also influence the efficiency of the ICE and of the MGU (Motor Generator Units). Energy evaluation of the TC readily exploits the concept. © 2006-2016 Asian Research Publishing Network (ARPN). All rights reserved.
