Abstract
To provide an exhaust gas purifying system capable of forcibly regenerating DPF by efficiently raising the temperature of exhaust gas even when an exhaust gas temperature is very low at the time of low load and low engine speed such as an idling operation. In an exhaust purifying system () having an exhaust throttling valve () and a DPF () in an exhaust passage and having regeneration control means (P) for regenerating the DPF (), the regeneration control means (P) is provided with an exhaust gas temperature detection means (P), a fuel injection control means (P), and an exhaust throttling control means (P) and includes regeneration control for performing the exhaust gas temperature raising control through the multistage delay injection by the fuel injection control means (P) and through the exhaust throttling of the exhaust throttling valve ().
