Fuel injection device for use in diesel particle filter regeneration installation of motor vehicle, has heat conductive porous material provided in pre-injection chamber for homogeneous heating of fuel to be injected into exhaust line

摘要

The device (10) has a fuel admission inlet (12) connected to a fuel tank, and a fuel receiving chamber i.e. cylindrical pre-injection chamber (14), providing gas to cause overheating by catalytic oxidation of exhaust gas. Heating element (16) heats the fuel in the pre-injection chamber. Heat conductive porous material (18) is provided in the pre-injection chamber for homogeneous heating of the fuel to be injected into an exhaust line. The material has a structure chosen among one of elements e.g. membranes, foams, strips, powders, granules and fibers. An independent claim is also included for a particle filter regeneration installation for motor vehicle, comprising a fuel tank.
