Document Type and Number:
Japanese Patent JP5376048
Kind Code:
B2
Abstract:
An exhaust purification system of an internal combustion engine, having an exhaust purification catalyst in the exhaust passage of the engine of a vehicle, a fuel supply device provided in the exhaust passage upstream the exhaust purification catalyst and supplies fuel to an exhaust gas flowing into the catalyst, a heating device which heats the fuel supplied from the fuel supply device, and a controller which controls the heating device. The controller controls the heating device, when a first processing request based on a state of the exhaust purification catalyst is standing and a second processing request based on an operating state of the vehicle is not standing (t2), to a pre-heating temperature lower than an ignition threshold capable of igniting the fuel and, when the first processing request and the second processing request are standing (t3), to an ignition temperature higher than the ignition threshold.
