DIESEL ENGINE

Japanese Patent JP2007051580

A

To provide a diesel engine which can relax the restriction of filter regeneration.

A control means 13 regulates the opening of an air quantity regulation valve 8 based on predetermined target temperature corresponding to fuel supply quantity. Feedback control to make detected temperature close to target temperature by reducing air supply quantity when detected temperature is higher than target temperature and increasing air supply quantity when detected temperature is lower than target temperature is performed. Yield of combustible gas 11 is made predetermined value or higher by the feedback control. A combustible gas supply passage 14 led out from an outlet side of a fuel reformer 3 is connected to an exhaust gas route 1 in an upstream of the filter 2, and combustible gas 11 is supplied to the exhaust gas route 1. Consequently, exhaust particulate matter accumulated in a filter 2 can be burned by combustion heat of combustible gas 11 burned by heat of exhaust gas 15.
