ターボと自然吸気は何が違うのか？あの加速を生み出す仕組みと、技術者たちが挑んだ弱点との戦い【自動車工学】

Which do you prefer: a turbo engine or a naturally aspirated (NA) engine? The sensual feeling of oneness between driver and machine with an NA engine that responds precisely to your commands is wonderful, but the "warp-like acceleration" of a turbo engine, with its strong torque rising from low RPMs and powerfully propelling the car forward, is also hard to resist. But putting that aside, why does simply having a different way of drawing in and feeding air create such a decisive difference in the driving experience? And how did the turbo, once criticized in the Showa era as "guzzling, fuel-inefficient, and difficult to handle," transform into a "savior of fuel-efficient eco-cars" in modern times? Let's discuss this at a leisurely pace.
