APPARATUS FOR INJECTING FUEL INTO THE COMBUSTION CHAMBERS OF INTERNAL-COMBUSTION ENGINES OF THE SELF-IGNITING KIND

摘要

The fuel injection nozzle (10) for a Diesel engine has a glow plug (20) which forms a hood over the nozzle end (24). The glow plug has a hole (28) in its hemispherical end through which the jet of fuel (18) flows. In the wall of the glow plug there are a number of radial holes (32) in the plane of the nozzle end face. The local zone of low pressure created by the jet issuing from the nozzle draws in air from the combustion chamber. This air mixes with the fuel and results in more complete combustion.
