本文表明，效率和扭矩输出的实际一级方程式动力装置主要取决于涡轮增压器（TC）的效率。压缩机和涡轮机的非设计效率和涡轮机能量回收能力应最大化，以最大化扭矩燃料比。由于较大的TC增加涡轮迟滞，本文提出了一种新的布局的中冷器。该解决方案减少了涡轮增压器，并使其能够专注于作为热机的TC效率。事实上，不仅TC设计选择可以从根本上改变TC本身的效率，而且还影响ICE和MGU（电动发电机组）的效率。TC的能量评估很容易利用这一概念。
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.
