Abstract

The invention relates to an apparatus for reducing oil leakage in a two-stage turbocharger, the apparatus comprises a transport section which connects a high-pressure turbocharger to a low-pressure turbocharger (200) for allowing clean air to be transported from the high-pressure turbocharger to the low-pressure turbocharger. The apparatus prevents lubricating oil in a bearing box dispersing to the rear surface of a compressor impeller through a piston ring, so that the leakage and consumption of the lubricating oil can be reduced.

Description

technical field [0001] The invention relates to a device for reducing lubricating oil leakage in a two-stage turbocharger of a vehicle, wherein the two-stage turbocharger consists of a high-pressure turbocharger and a low-pressure turbocharger. Background technique [0002] In a vehicle using a turbocharger engine, a two-stage turbocharger system equipped with a high-pressure turbocharger and a low-pressure turbocharger is used to provide optimum pressurized air to cover a wide driving range. The two-stage turbocharger system includes two turbochargers with different flow capacities, which are arranged on the exhaust passage of the exhaust manifold to use the high-pressure turbocharger in the range of low speed and low load, and in the A low-pressure turbocharger is used for high-pressure supercharging in the high-speed and high-load ranges. Furthermore, in a region where the turbocharger operates at a medium speed and a medium load, two-stage supercharging is performed usi...
