FIELD: engines and pumps.
SUBSTANCE: system of fuel spray to combustion chamber includes the first and the second fuel injectors. The first injector is located in the centre of the spray system with possibility of spraying the first fuel cloud. The second injector encloses the first injector with possibility of spraying the second fuel cloud of common ring shape around the first fuel cloud. The first and the second inlet air channels connected to the first and the second injectors respectively with possibility of forming the first and the second fuel-and-air mixtures. In addition, fuel spray system includes inlet air pipe with outlet holes between the first and the second injectors with possibility of forming a separating air film between combustion zones of the first and the second fuel-and-air mixtures.
EFFECT: reduction of environmental pollution.
