TEMPERATURE RAISING SYSTEM FOR AN EXHAUST GAS PURIFICATION CATALYST |
摘要 |
<p>A technique is provided which is capable of reducing an amount of smoke generated in a temperature raising system in which fuel added to an exhaust gas flowing through an exhaust passage is caused to combust at the time of requesting a temperature rise in an exhaust gas purification catalyst. When a request for raising the temperature of an exhaust gas purification catalyst (4) is made, bypass control is carried out in which the exhaust gas having bypassed a turbine (6b) is caused to flow into the exhaust gas purification catalyst (4) through a bypass passage (7), and fuel ignition control is carried out in which a fuel addition valve (9) is caused to add fuel to the exhaust gas which has flowed out of the turbine (6b), and a glow plug (10) is caused to ignite the added fuel.</p> |
