Abstract
A glow member, preferably in the shape of a ring, assists ignition and combustion of a fuel used in an internal combustion engine. A fuel injection valve injects a plurality of fuel jets directly into a combustion chamber during operation of the engine so that the fuel jets are aimed to the proximity of the glow member such that ignition of fuel in each fuel jet is assisted by the glow member. The glow member is made from high temperature materials and can include catalytic materials to further promote combustion. The glow member can be actively heated, for example by an electric current, in addition to being passively heated by the heat generated within the combustion chamber by the combustion of the fuel therein.
