Abstract

The design of injector nozzles providing improvement of the fuel injection and atomization processes quality in diesel engines is suggested. This is achieved by making grooves on the injector nozzle, each of which forms an expansion of the output channel of the corresponding spray hole. Experiments have been carried out for the D-245.12S diesel engine, alternately equipped with experimental and serial injector nozzles, and operated on diesel fuel, and on 80% diesel fuel and 20% rapeseed oil mixture. The possibility is demonstrated in terms of improving the exhaust gases toxic characteristics using the diesel engine equipped with the experimental injector nozzles and operated on 80% diesel fuel and 20% rapeseed oil mixture. The combination of the experimental nozzles and composite biofuel, containing 80% of diesel fuel and 20% of rapeseed oil, resulted in lower emissions of nitrogen oxides by 8.1%, of carbon monoxide—by 12.4%, and of unburned hydrocarbons—by 15.9%.
