ABSTRACT:
An apparatus for the injection of fuel into combustion chambers, in particular of self-igniting internal combustion engines, having an injection nozzle (10) and a subsequent glow body (20), which has a conduit (30) surrounded by heatable walls (26) and serving for the passage therethrough of the injected streams. At least one lateral opening (32) discharges into this conduit (30), the opening preferably communicating with a region (46) of the combustion chamber (36) remote from the core region of the ignition. The air aspirated through the lateral opening (32) warms up and enters into the peripheral zone of the injected streams, where the result is an air-fuel ratio and temperature conditions which are very favorable for ignition. Less heat energy is required to initiate the ignition than in the known apparatus of this general type. By eliminating the conventional glow plugs, which interrupt the movement of air in the combustion chambers, increased power is attained and the emission of soot is reduced sharply.
