Estimating the term…
An exhaust gas purification system includes the DPF to purify particulate matters in the exhaust gas of a diesel engine, comprising a regeneration control device to judge a condition of an engine operation to be an idle operation or not at the time of starting the control operation for regenerating the diesel particulate filter and during the regeneration control operation, when the engine operation is judged to be an idle operation, an idle engine speed is controlled and raised to the predetermined engine speed. Since the system includes such structure, in an operation of the DPF regenerate control, an adequate exhaust gas flow rate can be kept even in an idle operation and a raise of the DPF temperature due to a reduction of the exhaust gas flow rate can be avoided so as to prevent a damage of the DPF from melting and a deterioration of the catalyst.
An exhaust gas purification system comprising:
A method for controlling a regeneration of an exhaust purification system including a diesel particulate filter to purify particulate matters in an exhaust gas of a diesel engine, comprising:
A method for controlling regeneration of an exhaust purification system, including a particulate filter, comprising:
