Opis:: W pracy porównano elastyczność silników z systemem zasilania Common Rail oraz TDI. Zostało zebranych 10 typów wybranych silników z poszczególnych pojazdów o pojemności skokowej 2 dm³ z każdym z układów. Przeprowadzono analizę statystyczną – badano współczynnik zgodności, a więc zależność między wartościami teoretycznymi a rzeczywistymi, na podstawie dobranej krzywej trendu charakteryzującej się wysoką wartością współczynnika korelacji R² Uzyskano wysoką zgodność tych wyników. Oba typy silników były silnikami wysokoelastycznymi, jednak większą wartością tego parametru (elastyczności), istotnego w warunkach ruchu, charakteryzowały się silniki Common Rail.
At the work an elasticity of engines was compared with the Common Rail power system and TDI. 10 collected types of chosen engines were from individual vehicles about jumping capacity 2 dm³ with each of arrangements. A statistical analysis was conducted - a rate of the agreement, that is a relation were being examined between theoretical but real values, based on the selected curve of the trend being characterized by a maximum value of the coefficient of correlation R². A high unanimity of these results was get. Both types of engines were high-elastic engines, however with considerable value of this parameter (flexibilities), essential in conditions of the movement, Common Rail engines were characterized.

Opis:: Celem przeprowadzonych badań była analiza wpływu jakości paliwa na zużycie wybranych elementów układu Common Rail. Obiektem badań był silnik Fiat 1,3 Multijet z elektromagnetycznymi wtryskiwaczami o numerze katalogowym 0 445 110 083. Silnik pracował na zanieczyszczonym paliwie złej jakości. W celu oceny stanu technicznego wtryskiwaczy zdemontowano, zweryfikowano i wykonano testy wtryskiwaczy paliwa na urządzeniu firmy Bosch EPS 200 A. Badania pokazały, że jakość paliwa ma istotny wpływ na stan wtryskiwaczy.
The goal of the study was to evaluate the effects of the fuel quality on the wear of selected elements of the Common Rail system. The object of the study was the Fiat 1.3l Multijet engine with electromagnetic injection valves, with catalogue number 0 445 110 083. To operate the engine, low quality contaminated fuel was used. In order to assess the condition of the injection valves, they were taken apartand tested using the Bosch EPS 200A system. The study demonstrated that the fuel quality has a significant impact on the condition of the injection valves.

Tytuł:: The effect of pressure in a common rail accumulator on engine operating parameters
Autorzy:: Gołębiewski, W.
Powiązania:: https://bibliotekanauki.pl/articles/247960.pdf
Data publikacji:: 2012
Wydawca:: Instytut Techniczny Wojsk Lotniczych
Tematy:: Common Rail fuel injection system

Opis:: The issues addressed in this paper concern the effect of pressure in the Common Rail accumulator on the engine operating parameters such as its torque, power output, rotational speed as well as its hourly and specific fuel consumption. Here, the research methods were performed by using the engine test bench strictly in accordance with the specific standards but particularly according to the requirements specified by these standards. The research station was the Fiat Multijet 1.3 JTD engine with turbocharging and direct injection, used as a power unit in the motor cars. Additionally, the experimental tests were run by using also (1) the HP-made measuring set for measurements the high pressure (up to 2,500 bars) in the Common Rail system, and (2) the CDIF/2 diagnostic interface. All relationships are presented in the form of graphs, and what is found here is the increasing linear relationship between the p rail pressure and the engine speed: with an increase in speed comes a decrease in the total injection time. The torque and its power output were a function of both the pressure in the Common Rail accumulator and the speed. It was found that the highest total engine efficiency (fuel consumption per unit) was for the rail pressure ranging from 1,000 to 1,100 bars. The findings come up for discussion about the apt choice of pressure in the rail, together with the total injection time and the turbocharger highest efficiency, for the specified speed of a car power unit.

Tytuł:: The impact of air filter on operational properties of engine with the common rail fuel supply system

Opis:: The objective of this research project was to determine the percentage impact of dry-medium air filter being used in Fiat Multijet 1.3 JTD engine on its operational properties (engine flexibility and specific fuel consumption). Experiments were performed according to the requirements of research methods specified in the piston combustion engine standard in force. In order to make comparisons, operational parameters of the power unit (torque, effective power and specific fuel consumption) were measured with dry-medium air filter (with a new filter element) being fitted and with air filter being removed. Each point of respective characteristic curves was determined based on four measurements as their mean value. Also boost pressure, which could be of importance for results, was considered in the experiments. However, the degree of EGR valve lift, the operation of which could also appear to be important, was not taken into account. For each measuring point of respective characteristic curves, the ranges of measurement uncertainties were determined. Expanded standard uncertainties were calculated based on the Guide to the Expression of Uncertainty in Measurement. The experiments being carried out allowed concluding that the engine with air filter was less flexible by approx. 20% when compared to that without air filter, whereas its specific fuel consumption was greater by approx. 9%. The degree of air filter pollution affects its flow resistance and, which is related to this, engine torque and its effective power as well as its flexibility decrease but fuel consumption increases

Opis:: Article describes the operation issues of contemporary injection systems of Diesel engines. Common-rail system has been used since 1997, and since then there has been a significant evolution in its construction. In this aspect, there are changes in generations of high-pressure injection pumps and fuel injectors as well as methods of steering them, but exploitation problems are the same. The most prone to malfunction elements of the system are the fuel injectors. Their task is to distribute and to spray of the fuel in the combustion chamber of engine. Common Rail fuel injectors generate few injection dosages in the one work cycle. The rate of injection is depended on the design of the steering valve. One very important parameter of fuel injector is fuel injection delay time. If the time from control start of fuel injector to begin injection is shorter then it causes generation of greater number of injection dosages. Pollutants in fuel in the form of various amorphous solids of the size an even few microns cause the decrease of operating parameters of injector, which adversely affects the operation of the engine. Article shows contemporary fuel injectors, the methods of their examination, the types of fuel pollutants and their impact on fuel injector work.
