Abstract

A fuel reforming system for a vehicle intake and exhaust line that reforms fuel in a vehicle intake and exhaust line including an exhaust gas recirculation (EGR) apparatus that recirculates a portion of an exhaust gas of an engine and a recirculation line that transfers an exhaust gas that is recirculated by the exhaust gas recirculation apparatus to supply as an intake gas of the engine, may include a fuel reformer that mixes an exhaust gas that passes through the recirculation line with fuel and that reforms fuel that is mixed in the exhaust gas, wherein an insulation material is coated at a wall surface of the fuel reformer.

First claim

What is claimed is:

1. A fuel reforming system for a vehicle intake and exhaust line that reforms fuel in the vehicle intake and exhaust line having an exhaust gas recirculation (EGR) apparatus that recirculates a portion of an exhaust gas of an engine and a recirculation line that transfers the exhaust gas that is recirculated by the exhaust gas recirculation apparatus to supply as an intake gas of the engine, the fuel reforming system comprising:
a fuel reformer that mixes an exhaust gas that passes through the recirculation line with fuel and that reforms fuel that is mixed in the exhaust gas,
wherein an insulation material is coated at a wall surface of the fuel reformer, and
wherein a thickness of the coated insulation material is 100 μm to 300 μm,
wherein the fuel reformer includes:
an inlet that receives an exhaust gas that passes through the recirculation line;
a mixing portion that mixes an exhaust gas that is entered into the inlet with fuel;
a reforming portion that reforms fuel that is mixed with an exhaust gas in the mixing portion; and
an outlet that discharges an exhaust gas that passes through the reforming portion to the recirculation line, and

wherein the insulation material is coated at an internal surface of the inlet, the outlet, the mixing portion, and the reforming portion, and
wherein in the recirculation line, the insulation material is coated.

2. The fuel reforming system of claim 1 , wherein the insulation material contains aerogel of 15 wt. % or more.

3. The fuel reforming system of claim 1 , wherein in the mixing portion, a mixing chamber, which is a region that is communicated with the inlet to mix an exhaust gas and fuel is formed, and in the mixing chamber, an injector that ejects fuel is provided.

4. The fuel reforming system of claim 1 , wherein a disposition region of a catalyst that reforms fuel is formed within the reforming portion.

5. The fuel reforming system of claim 4 , wherein the catalyst reforms fuel to have a high hydrogen content.

6. The fuel reforming system of claim 1 , wherein the insulation material is coated on an internal surface of the recirculation line.
