Problems solved by technology

In addition, the EGR gas must be sufficiently heated to obtain a sufficient fuel reforming activation temperature, however, it is difficult to obtain the activation temperature depending on the driving conditions and the supply amount of EGR gas
We have found that there is a problem of a drop in reforming efficiency due to a significant drop in the temperature of the mixed gas during the mixing of fuel and EGR gas in the mixing section of the fuel reformer

Abstract

The invention discloses a fuel reforming system. The fuel reforming system includes: an engine combusting reformed gas to generate mechanical power; an intake line connected to the engine to supply the reformed gas and air to the engine; an exhaust line connected to the engine to circulate the exhaust gas discharged from the engine; a fuel reformer provided at an exhaust gas recirculation (EGR) line diverging from the exhaust line; and a catalyst disposed at the exhaust line and purifying nitrogen oxide included in the exhaust gas at a front end of the fuel reformer. In particular, the fuel reformer mixes the fuel with the EGR gas which is a part of the exhaust gas and passes through the EGR line, and reforms the fuel mixed in the EGR gas.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0169865 filed on December 13, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a fuel reforming system. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Generally, an exhaust gas recirculation (EGR) system is a system installed in a vehicle to reduce harmful exhaust gas. [0006] The exhaust gas recirculation system reduces the oxygen content in the mixer, reduces the amount of exhaust gas, and reduces toxic substances in the exhaust gas by circulating a part of the exhaust gas exhausted from the engine. [0007] Also, the temperature of the exhaust gas discharged from the engine is high, so the engine efficiency can be impr...
