    摘要： A fuel reforming system is provided. The system includes an engine combusting reformed gas to generate mechanical power and an intake line connected with the engine to supply the reformed gas and air to the engine. An exhaust line is connected with the engine to circulate exhaust gas and a fuel reformer disposed at an exhaust gas recirculation (EGR) line diverging from the exhaust line mixes the exhaust gas passing through the EGR line with fuel and reforms the mixed fuel. An exhaust gas purifying catalyst disposed at the exhaust line purifies nitrogen oxide in the exhaust gas. A temperature sensor at the exhaust line of the exhaust gas purifying catalyst measures temperature of the exhaust gas purifying catalyst. A bypass controller then operates a bypass valve to supply or cut off the exhaust gas into the fuel reformer according to temperature of the exhaust gas purifying catalyst.

    摘要： A 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.

    摘要： A continuously variable valve timing device is provided and includes a cam sprocket connected with a camshaft having a plurality of cams to rotate the camshaft and an electric variable valve timing mechanism connected with the cam sprocket, and driven by an electric motor. A chain cover protects the cam sprocket and a chain system from foreign substances and an electric variable valve timing mechanism cover protects the electric variable valve timing mechanism from foreign substances. A seal ring partitions an internal space between the electric variable valve timing mechanism and the electric variable valve timing mechanism cover. In addition, a pressure maintaining device is mounted within the electric variable valve timing mechanism cover to maintain pressure formed within the internal space of the electric variable valve timing mechanism cover at about atmospheric pressure.
