PURPOSE:To prevent the temperature rise of fuel, by extending a heat radiating plate consisting of a material having a good heat conductivity into the interior of a delivery pipe from the base end of a cylindrical housing on the end of which a nozzle is opened, and positioning it in fuel. CONSTITUTION:When a plurality of electromagnetic fuel injection valves are provided for each cylinder, they are commonly connected to a delivery pipe D. Herein, in the cylindrical housing 1 having a nozzle opening 111 at the end, the upper end part of the cylindrical fixed core 13 at the base end part thereof is sufficiently extended into the delivery pipe D as a heat radiating part 134, on which a large number of through holes 135 are formed. Since the fixed core 13 including this heat radiating part 134 is made up of an electromagnetic stainless steel having a good magnetic characteristic and heat conductivity, the heat from an intake manifold M is efficiently radiated into the fuel in the delivery pipe D. Thus, the vaporization of fuel remaining inside the housing can be prevented, enabling a fuel injection good in accuracy to be carried out. |
