一种废气涡轮增压器及方法

Exhaust gas turbocharger and method

Abstract

The invention discloses an exhaust gas turbocharger and a method and relates to the field of automobile power devices. The exhaust gas turbocharger comprises a compressor used for compressing air and delivering a part of compressed air into a cylinder from an air outlet of the compressor through an engine inlet manifold, a turbine chamber utilizing rotation of a turbine to drive a coaxial impeller to compress the air, an air storage device used for receiving and storing the other part of compressed air produced by the air compressor and discharging the compressed air to the turbine chamber, a first electromagnetic valve used for controlling the on-off state of a pipe between the compressor and the air storage device and a second electromagnetic valve used for controlling the on-off state of a pipe between the air storage device and the turbine chamber and a controller determining the on-off state of the first electromagnetic valve and the second electromagnetic valve. By means of the turbocharger and the method, the relevant problem that a traditional exhaust gas turbocharger responds at low speed, a venting valve generates noise and the like can be solved.
本发明公开了一种废气涡轮增压器及方法,涉及汽车动力设备领域。所述废气涡轮增压器包括:用于压缩空气并通过压缩机的出气口将压缩后的一部分空气通过发动机进气歧管送入气缸的压缩机;通过涡轮的转动带动同轴的叶轮对空气进行压缩的涡轮室;接收并存储压缩机产生的另一部分压缩空气、排出压缩空气到涡轮室的储气装置;控制压缩机和储气装置间管道通断的第一电磁阀和控制储气装置和涡轮室间管道通断的第二电磁阀;决定第一、第二电磁阀的通断的控制器。此设计能改善传统废气涡轮增压器低速响应、泄流阀产生噪音等相关问题。
