The article presents the results of empirical research and their analysis regarding the impact of diesel oil and diesel oil mixture with bioethanol on coking the test injector nozzles of the XUD9 engine from PSA. The research included three fuel deals: diesel fuel as the base fuel and diesel oil mix with ONE10 bioethanol (10% bioethanol plus diesel oil (V/V)), ONE20 (20% bioethanol plus diesel oil (V/V)). They were conducted on the basis of CEC PF-023 developed by CEC (Coordinating European Council). Each of the abovementioned fuels was tested using a new set of injectors. The propensity of the fuel for coking the injector tips was expressed as a percentage reduction in the air flow through the nozzles of each injector for the given sheer increments. The test result was the average percentage of airflow reduction for all nozzles at 0.1 mm spike increments and was measured according to ISO 4010 "Diesel engines. Calibrating nozzle, delay pintle type”. The test results for individual atomizers of the above-mentioned test engine in the area of sediment formation from flowing fuel shown a lower tendency to coke the injectors using diesel fuel-bioethanol in comparison to the use of pure diesel oil. Based on the CEC PF-023 test, it can be noticed that the level of contamination of the tested injectors for ONE10 fuel is about 3% lower, and for ONE20 fuel is about 4% lower than the level of pollution for diesel fuel.

The article presents the results of the influence of injection of mineral fuels and biodiesel on the injectors coking in compression ignition engine type XUD9 manufactured PSA. During the test, the engine worked in accordance with the procedures of ISO 15550-1. The study included five fuels: diesel oil (base fuel), the pure esters from Camelina L100, and a mixture of the diesel fuel and Camelina: L10 (10% L100 plus diesel oil), L20 (20% L100 plus diesel), L30 (30% L100 plus diesel). The tests were performed on the basis of the CEC PF-023 developed and introduced by the CEC (Coordinating European Council). For each tested fuel was used the new injector set. Results of flow concentration the fuel was presented on the diagrams.

Artykuł przedstawia rezultaty wpływu wtrysku paliw mineralnych oraz biopaliw na koksowanie końcówek wtryskiwaczy silnika XUD9 firmy PSA. Podczas testu silnik pracował według procedury ISO 15550-1. Badania obejmowały pięć typów paliwa: olej napędowy jako paliwo bazowe, czysty ester oleju lniankowego L100, oraz mieszaniny oleju i estru: L10 (10% L100 reszta olej napędowy), L20% (20% L100 reszta olej napędowy), L30 (30% L100 reszta olej napędowy). Testy były prowadzone na podstawie CEC PF-023 opracowane przez CEC (Coordinating European Council). Każde paliwo było badane przy użyciu nowego zestawu wtryskiwaczy. Wyniki zostały zaprezentowane na wykresach przedstawiających przepływ paliwa przez wtryskiwacze.

Bardzo często zdarza się, że silniki rolnicze podczas prac rolnych pracują pod różnymi obciążeniami i ma to duży wpływ na operacyjne wskaźniki ich pracy. Zamierzeniem autorów było przeprowadzenie badań eksperymentalnych, dotyczących zastosowania do zasilania silników rolniczych o zapłonie samoczynnym paliw pochodzenia roślinnego, bez dokonywania kosztownych modernizacji konstrukcyjnych silników. Celem badań była ocena wpływu zasilania silnika PERKINS 1104C-E44T estrem metylowym kwasów oleju rydzowego ESTLN (100%) oraz porównawczo olejem napędowym ON (EkoDiesel ULTRA - B) na efektywne i ekonomiczne wskaźniki jego pracy. Badania prowadzone były na bazie charakterystyk obciążeniowych z wykorzystaniem stanowiska badawczego wyposażonego w system pomiarowy wielkości wolno i szybkozmiennych. Zastosowanie paliw o różnych właściwościach fizykochemicznych do silników o zapłonie samoczynnym wymaga dużych dokładności pomiarów celem poznania występujących różnic w procesach wtrysku i spalania silników zasilanych tymi paliwami mających później odzwierciedlenie w wskaźnikach operacyjnych pracy silnika.

Very often it happens that agricultural engines work during agricultural work under various loads and has a great impact on the working indicators of their work. The intention of the authors was to conduct experimental studies on the use of agricultural engines to power the ignition of fuels of vegetable origin, without expensive structural modernization of engines . The aim of the study was to check the impact of power PERKINS 1104C- E44TA ester of camelina EST -LN (100 %) and comparatively diesel oil ON (Ekodiesel - ULTRA -B) for efficient and economic indicators of his work. Tests were carried out on the basis of load characteristics using a bench with a system of measuring the size of slow and fast-changing. The use of fuels with different physicochemical properties for compression-ignition engines need high accuracy measurement objective knowledge of the existing differences in the processes of injection and combustion of these fuels for engines fueled with later reflected in the operating ratios of engine operation.

This paper presents the results of comparative research on basic physical and chemical properties of pure diesel fuel and two types’ mixtures of Camelina oil ester (Camelina oil ester content of the mixture was 10% and 15%) and diesel fuel. Application of these mixtures has different physicochemical properties to power supply diesel engine, made it possible to detect existing differences in the injection process (pumping and spraying). The analysis of the injection process has been defined through experimental graphs of the fuel pressure in injection line and registered height of the needle injector. With the knowledge of these two fast-changing engine parameters and load􀀐velocity conditions, there were calculated: fuel flow speed from nozzle, range and fuel spray disintegration time and the average critical diameter of the droplets. In the final part of the article it was shown, that the fuel with different physicochemical properties has a significant impact on the injection process. There were also made a comparative assessment of the suitability test compounds for use in service.
