An automatic is a device that provides gear reduction, with resulting multiplication of torque.

自动变速器是一个提供减速、同时增加扭矩的装置。

Turbocharger engine can not meet all the needs of the operational state, resulting in the part-load torque inadequate and heat load increases.

涡轮增压器不能满足柴油机全工况运行的需要，使部分负荷扭矩不足，热负荷增大。

Torque and power are enhanced in full load resulting from increasing intake gas mass.

全负荷工况增加进气流量，提高了动力性。
