System and method for removing condensate water of an intercooler for a hybrid vehicle

Abstract

A system and method for removing condensate water of an intercooler for a hybrid vehicle are configured to improve combustion efficiency of an engine by supercharging intake air to a combustion chamber of the engine using an electronic compressor instead of an existing turbocharger and configured to backward drive the electronic compressor to distribute and capture the condensate water generated in the intercooler, especially, when the engine is turned off.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims under 35 U.S.C. § 119(a) the benefit of priority to Korean Patent Application No. 10-2021-0059702 filed on May 10, 2021, the entire contents of which are incorporated herein by reference.BACKGROUND(a) Technical Field[0002]The present disclosure relates to a system and method for removing condensate water produced by an intercooler for a hybrid vehicle, and more particularly, to such a system and method which are configured to distribute and capture the condensate water generated in the intercooler using backward driving of an electronic compressor.(b) Background Art[0003]As is well-known, a hybrid vehicle that is a kind of eco-friendly vehicle refers to a vehicle in which a motor and an engine are both used as a driving source.[0004]For the purpose of reducing exhaust gas and improving engine efficiency, a turbocharger made up of a turbine, a compressor, an exhaust gas recirculation (EGR) valve for recirculating the...

AI Technical Summary

Benefits of technology

The solution effectively eliminates turbo lag, prevents engine misfires and intercooler breakage, and maximizes fuel efficiency by capturing and managing condensate water, ensuring efficient engine operation and reduced emissions.

Problems solved by technology

However, when fresh air is supercharged to the combustion chamber of the engine by driving the turbine and the compressor of the turbocharger and is cooled in the intercooler, a lot of condensate water is generated, and thus the following problems are caused.

First, there is a problem in that the condensate water generated in the intercooler after the engine is turned off flows into the combustion chamber in a moment when the engine is turned on, and thus causes engine misfire.

Second, there is a problem in that, due to freezing of the condensate water accumulated in the intercooler in the winter, a breakage phenomenon of the intercooler is caused, or pieces of ice flow into the combustion chamber, which causes engine misfire.

Third, deterioration of fuel efficiency resulting from a reduction in operating range of the turbocharger and the EGR may be caused under a low-temperature high-humidity condition under which the condensate water is excessively generated.
