Air pressure boosting devices include the following types:

1. 涡轮增压器（Turbocharger）：通过废气的能量驱动轴向涡轮，使压缩空气进一步增压，然后送入发动机燃烧室。涡轮增压器主要用于内燃机，通过提高气缸充气效果，以增加输出功率和扭矩。

1. Turbocharger: The axial turbine is driven by the energy of exhaust gas, which further pressurizes the compressed air and then sends it into the engine combustion chamber. Turbochargers are mainly used in internal combustion engines to increase output power and torque by improving the cylinder inflation effect.

2. 机械增压器（Supercharger）：机械增压器是通过由发动机驱动的离心或螺杆等压缩器来提供更多的进气，从而增加气缸内燃烧室的空气密度和气压。与涡轮增压器不同的是，机械增压器不利用废气能量，而是靠发动机直接驱动。

2. Supercharger: Supercharger provides more intake air through compressors such as centrifugal or screw driven by the engine, so as to increase the Density of air and pressure of combustion chamber in the cylinder. Different from the turbocharger, the Supercharger does not use exhaust gas energy, but is directly driven by the engine.

3. 电动增压器（Electric Supercharger）：电动增压器是一种通过电机驱动的压缩器，通常与传统的涡轮增压器或机械增压器结合使用。它能够在低转速时快速为发动机提供额外的压缩空气，以减少涡轮增压器的涡轮滞后和机械增压器的惯性效应。

3. Electric supercharger: electric supercharger is a compressor driven by a motor, which is usually used in combination with traditional turbocharger or Supercharger. It can quickly provide additional compressed air for the engine at low speed to reduce the turbine lag of the turbocharger and the inertia effect of the Supercharger.

4. 液体增压器（Liquid Charger）：液体增压器通过水或其他液体的喷射来提供额外的气流增压。液体增压器可以使用水喷嘴将水喷入空气中，利用水蒸气的膨胀作用来增压。

4. Liquid Charger: A liquid supercharger provides additional airflow pressure through the injection of water or other liquids. A liquid booster can use a water nozzle to spray water into the air, utilizing the expansion effect of water vapor to boost pressure.

以上是常见的几种气压增压装置，它们在汽车、柴油发电机组等内燃机系统中得到广泛应用，以提高燃烧效率和动力输出。

The above are several common air pressure turbocharging devices, which are widely used in internal combustion engine systems such as automobiles and diesel generator sets to improve combustion efficiency and power output.
