Abstract

Motorna vozila koja za svoje kretanje koriste motore s unutarnjim izgaranjem u cilindre
motora ubrizgavaju gorivo u obliku spreja. Kako bi se ubrizgivanje spreja moglo optimizirati, uslikane su slike spreja goriva koji ulazi u cilindre. Slike su segementirane metodama
dubokog ucenja i analizirane. Analiza uklju ˇ cuje odre ˇ divanje duljine penetracije spreja i kut ¯
raspršenja. Kako bi se slike segmentiranle, korištena je konvolucijska neuronska mreža koja
se sastoji od konvolucijskih slojeva. Mreža je po arhitekturi U-Net i sastoji se od dva dijela
cija je uloga opisana u radu.

Abstract (english)

Motor vehicles that use internal combustion engines inject a spray of fuel into the cylinders of their engine. In order to optimize the spray injection, images of the fuel spray entering the cylinders were taken. Images are segmented using the deep learning methods and
analyzed. The analysis includes determining the spray penetration length and spray angle.
In order for images to be segmented, a convolutional neural network consisting of convolutional layers is used. The network is based on the U-Net architecture and consists of two parts
whose role is described in the paper.
