For the CNG engine, VW primarily focused on the fuel induction system of the unit as well as pushing the turbocharger to the limit in terms of stable temperature. 的天然氣發(fā)動(dòng)機，大眾汽車(chē)主要集中在燃料感應系統的單位，以及推動(dòng)渦輪增壓器的極限在穩定的溫度。
The high helix rotor design both improves the supercharger thermodynamic efficiency and improves noise quality to the point where the unit is virtually inaudible. 高螺旋轉子設計既提高了增壓器熱力學(xué)效率和質(zhì)量，以提高噪聲的地步單位幾乎是聽(tīng)不見(jiàn)的。
