The paper presents the results of research on the fuel injection and atomization process in a PERKINS 1104C-44 engine operating according to external speed characteristics, fueled with: mixtures of low-sulfur diesel and biobutanol, and, for comparison, EKODIESEL ULTRA B fuel. Measurements were performed on a dynamometer test bench equipped with a high-speed data acquisition system. It was demonstrated that the type of fuel with different physicochemical properties has a significant impact on the fuel injection and atomization process. Analysis of experimentally generated fuel pressure charts in the injection line and injector needle lift enabled the determination of: fuel discharge velocity from the nozzle, as well as the length and disintegration of the fuel spray into droplets.INFLUENCE OF FEEDING OF THE AGRICULTURAL ENGINE WITH THE ADDITION BIOBUTANOL TO THE DIESEL FUEL TO CHOSEN PARAMETERS OF THE PROCESS OF THE FUEL INJECTION
In the paper research findings of the course of the process of injection and spraying fuel to drops in the PERKINS-1104C-44 engine working according to outside characteristics were introduced, powered: with mixtures of low-sulphuric diesel with biobutanol and comparatively fuel EKODIESEL ULTRA B. Measurements were made on the post equipped with the system of measurements of fast-changeable sizes. They demonstrated, that kind of fuel about different properties physicochemical an essential influence on the process of injection and spraying fuel has. Analysis of graphs experimentally made out of the pressure of fuel in the injection wire and enabled the growth of the netting needle of the injector outlining: speeds of the leakage of fuel out of the sprayer and the length and the disintegration of the stream of fuel to drops.
