Opis:
In this paper, a novel fuel-injection mechatronic control method and system for direct injection (DI) internal combustion engines (ICE) is proposed. This method and system is based on the energy saving in a capacitance using DC-DC converter, giving a very fast ON state of the fuel injectors’ electro-magnetic fluidical valves without an application of the initial load current. A fuel-injection controller for the DI ICEs that provides a very short rising time of an electromagnet-winding current in an initial ON state of the fuel-injector’s electromagnetic fluidical valves, which improves a fuel-injection controller reliability and simplify its construction, is presented. Due to a number of advantages of afore -mentioned fuel-injection mechatronic control method and system, it may be utilised for the DI ICEs with fuel injectors dedicated to all types of liquid and/or gas fuels, for example, gasoline, diesel-oil, alkohol, LPG and NPG.

Opis:
The storage supply systems of Common Rail type are characterized by high possibilities in shaping the rate of injection. The possibility to implement multi-injection at high pressure, easiness of adapting the system to the engine, relatively easiness of compensation the arrangement of injector parameters resulting from work tolerance, as well as easiness of making changes in the electronic engine controller enabling the production of engines with various performances, cause that type of these solutions currently are widely used injection systems in diesel engines. Injection system should be characterized above all by high precision fuel dosing into engine cylinders, the accuracy in starts controlling of individual phase of injection, repeatability and reliability and durability, as well as the up keep of these parameters for long time during operating duration. Fuel injection system works in difficult conditions resulting from high pressure, vibrations, electromagnetic interference affecting electronic executive systems and high temperatures. Especially the injector and injection pipes are open to high temperatures. The dimensions of used elements are also important. The article presents selected results concerning the effect of the length of high-pressure pipes on injection process parameters such as fuel amount, overflow in injector, and the fuel pressure course in injection pipe in front of electromagnetic injector socket. The study was conducted with test stand with electronic measurement system of fuel amount. The tests were made at different pressures in the rail and for different durations of the injector opening.

Opis:
In recent years the compression ignition engines with direct injection equipped with common rail system are subject to intensive development. Mainly, the reason for it the ecological considerations are. Generally the engines of this type are characterized by relatively low specific fuel consumption, lower noisy and lower emission of toxicity components in relation to DI engines with conventional injection system. Especially the main advantage of common rail system is possibility of easy controlling the injection parameters. Therefore a very important is parameters of control signals of injection system, including injectors, because they have the influence on fuel amount. In the article the effect of CR injector control signal on injection process was presented. The measurements were taken at constant frequency running of injector and set values of rail pressure. The temperature of injected fuel was controlled also. The researches were conducted with test stand equipped with test bench with electronic measuring offuel amount. In the centre of attention was peak current-duration at set values of injector opening signal. The tests were conducted at single injection and for two types of injector.
Intensywny rozwój silników wysokoprężnych z bezpośrednim wtryskiem paliwa, wyposażonych w akumulacyjne układy zasilania typu Common Rail, jest podyktowany głównie względami ekologicznymi. Ogólnie, silniki tego typu charakteryzują się stosunkowo niskim jednostkowym zużyciem paliwa, mniejszą hałaśliwością i mniejszą emisją toksycznych składników spalin w stosunku do silników typu DI z konwencjonalnym układem wtryskowym. Szczególnie ważną zaletą zasobnikowych układów wtryskowych jest możliwość łatwego sterowania parametrami wtrysku. Bardzo istotne są przy tym parametry sygnałów sterujących elementami układu wtryskowego, w tym wtryskiwaczy, gdyż oddziałują one bezpośrednio na wielkość dawki paliwa. W artykule przedstawiono wpływ wybranych parametrów sygnału sterującego wtryskiwacza typu CR na proces wtrysku paliwa. Pomiary realizowano dla stałych wartości częstotliwości pracy wtryskiwacza oraz zadanych wartości ciśnienia w szynie zasilającej wtryskiwacz. Kontroli podlegała także temperatura wtrysku paliwa. W badaniach, które prowadzono na stole probierczym wyposażonym w system elektronicznego pomiaru dawki paliwa, szczególną uwagę zwrócono na czas fazy załączania wtryskiwacza, przy ustalonych długościach sygnału otwarcia wtryskiwacza, w warunkach wtrysku jednofazowego dla dwóch różnych typów wtryskiwacza.

Opis:
In recent years, the compression ignition engines with direct injection equipped with common rail system are subject to intensive development. Mainly, the reason for it the ecological considerations are. Generally, the engines of this type are characterized by relatively low specific fuel consumption, lower noisy and lower emission of toxicity components in relation to DI engines with conventional injection system. Especially the main advantage of common rail system is possibility of easy controlling the injection parameters. Particularly a possibility of splitting the fuel dose into several parts within the one engine cycle permits to influence on combustion process. In the paper, the effect of injection characteristic on NOX formation in DI engine equipped with common rail injection system is presented. In principle, the course of injection by pilot, preinjection and main fuel dose was shaped. The fuel dose quantities were changing by choosing of injector opening duration. The distances between parts of injection were changed too. The researches were conducted at constant rotational speed of engine. Whole researches by using the test engine equipped with common rail injection system were realized. The following parameters were measured during researches: rotational speed, power, hour fuel consumption, rate of air flow into engine and concentration of NOX and HC in exhaust gases. Also high speed parameters were recorded such as pressure in combustion chamber, injector control signals and pressure in inlet manifold.
W ostatnich latach intensywnemu rozwojowi podlegają silniki wysokoprężne z bezpośrednim wtryskiem paliwa wyposażone w akumulacyjne układy zasilania typu Common Rail. Jest to podyktowane głównie względami ekologicznymi. Ogólnie, silniki tego typu charakteryzują się stosunkowo niskim jednostkowym zużyciem paliwa, mniejszą hałaśliwością i mniejszą emisją toksycznych składników spalin w stosunku do silników typu DI z konwencjonalnym układem wtryskowym. Szczególnie ważną zaletą zasobnikowych układów wtryskowych jest możliwość łatwego sterowania parametrami wtrysku. Zwłaszcza możliwość podziału dawki paliwa na kilka części w obrębie jednego cyklu pracy silnika pozwala na istotne oddziaływanie na przebieg procesu spalania. W artykule przedstawiono wpływ charakterystyki wtrysku na powstawanie NOX w silniku typu DI wyposażonym w układ wtryskowy typu Common Rail. Charakterystyka wtrysku zasadniczo ukształtowana była przez dawkę pilotującą, przedwtryskową i zasadniczą. Wielkość tych dawek zmieniana była przez zmianę czasu otwarcia wtryskiwacza. Zmianom podlegały także odległości kątowe pomiędzy składowymi dawki paliwa. Badania prowadzone były przy stałej prędkości obrotowej silnika. Całość badań realizowana była na jednocylindrowym silniku badawczym z zaadoptowanym do niego układem wtryskowym typu Common Rail. Podczas badań pomiarom podlegały między innymi następujące parametry: prędkość obrotowa, moc, godzinowe zużycie paliwa, masowe natężenie przepływu powietrza do silnika oraz stężenie tlenków azotu NOX i węglowodorów HC w spalinach. Rejestrowano także parametry szybkozmienne takie jak: ciśnienie w komorze spalania, sygnały sterujące pracą wtryskiwaczy, ciśnienie w układzie dolotowym.

Opis:
Results presented in the article regard the research on a turbocharged dual-fuel CI engine operating on propane. The research indicated that such engine might operate even if 70% of the standard fuel energy is replaced by propane. The research indicated that at such high share of the gaseous fuel, there is necessary to adjust diesel fuel injection parameters but it is important that there is no need to change the engine structure. Injection parameters may be adjusted in a wide range due to the modern fuelling system of the common rail type. The investigated engine was equipped with such system. Adjustments regarding the fuel charge division, fuel charge quantities, and injection timing enabled to influence combustion in such way to obtain its specific parameters, i.e. maximum combustion pressure, rate of pressure rise, maximum pressure, and the burn out ratio similar to those obtained for diesel fuel operation. The obtained results were presented in form of adjustment characteristics of the injection timing of diesel fuel pilot dose for a few chosen values of the boost pressure as well as injection timing of the main dose. The investigations were carried out for three values of the boost pressure, i.e. 200; 400 and 600 [mbar] but also for the naturally aspirated version. Injection timing of the first dose varied in a broad range and depended on the boost pressure. Injection timing of the second dose varied in a narrower range, mainly due to considerable changes in the combustion process. The obtained results answered a number of questions regarding the strategy of selection of diesel fuel injection parameters taking into consideration engine performances as well as combustion at a high share of the gaseous fuel.

Opis:
Control of diesel fuel injection is very important and has influence not only at engine operating conditions but also at emission of toxic gases as NOx, HC, and Particulate Matter (PM) are effect of combustion process. Directly observing of combustion process is very difficult, but implementation to injection control algorithm procedures based on additional sensors as knock sensor, cylinder pressure sensor and observing of rotational speed course could give enough information to optimize control algorithm. In traditional diffusion-burn diesel combustion start of combustion occurs a cetane-number based time delay after the start of the fuel injection. To fulfill of new emission standards is need to observing not only start of combustion but also whole combustion process. In the paper conception of injection control system applied with combustion process observer based on additional sensors. Closed-loop feedback control of cylinder pressure sensor and advanced control algorithm with high-resolution rotational speed sensor offers the potential to improve controllability of combustion process. Advanced control system based on heat release estimated from cylinder pressure and rotational speed fluctuations enabling improving engine exhaust emissions, engine performance and reduced noise emission. Introducing into control system a low cost glow plug integrated cylinder pressure sensor allow to achieve complete injection control system with advanced functions which could be very effective also in aspect of fuel consumption reduction.

Opis:
The basic aim in controlling the diesel engine is to obtain a maximal effective torque for a given fuel dose with keeping at minimum toxic exhaust compounds. This postulate can be realized by matching the appropriate fuel injection timing. In this paper the research results of the control system are presented, which allow for the constant matching of the injection advance in the CI engine to the varying characteristics of the controlled object, that is the engine. Quality factor of the working process which is defined as an effective engine torque, is estimated on the base of the instantaneous crankshaft torsion measurement. This concept, unlike the currently used systems, suggest the use of efficient torque (Me) measurement to generate control quantities, which control the work process of an engine. Realization of such measurements leads to the treatment of the control system as an extreme control unit (maximizing quantitative parameters) as well as an adaptive control system (possibility of unit's reaction on high changes of the parameters influencing the work process of an engine). Combining the idea of the crankshaft torsion measurement with the idea of extreme control, a system can be designed, which makes use of torsion measurement for the adaptive control of the injection timing. The object of the research was a Diesel engine ISUZU Y17DT with electronically controlled injection pump and engine diagnostic system. Realization of the research aim required design and construction of the measurement system of the crankshaft torsion.

Opis:
With the continuous increase of output power ratings, multi-phase (multichannel) interleaved power factor corrector (IPFC) is gradually employed in domestic and commercial inverter air-conditioners. IPFC can solve several main problems, such as power rating increase, power device selection, input current ripple reduction as well as inductor on-board mounting. But for a multi-phase IPFC, the key problem is that it should show rapid dynamic responds and good current sharing capability, so in this paper the aim is to improve the dynamic performance and current sharing capability by means of passivity control theory. Considering the power circuit topology of a four-phase IPFC, an EL (Euler-Lagrange) mathematical model is established when the IPFC operates in continuous conduction mode (CCM). Then the passivity of the four-phase IPFC is proved, and the passivity-based controller using the state variables feedback and damping injection method is designed. The proposed control scheme, which is easy to control and needs no proportion integral controller, has strong robustness on disturbance from singlephase AC input voltage, the load as well as the parameters of the employed devices. Even in wide-range load condition, the mains current has a fast dynamic response and the average output voltage almost keep unchanged. As a result, the main functions of the four-phase IPFC are implemented including nearly unitary power factor and constant DC output voltage. Meanwhile, the four-phase IPFC acquires an excellent current sparing effect after using passivity-based controller. The above analysis has been proved with simulated results by means of MATLAB/SIMULINK and experimental results, showing that the passivity-based IPFC controller has superior performances and feasibility.

Opis:
This paper proposes a methodology based on installation cost for locating the optimal position of interline power flow controller (IPFC) in a power system network. Here both conventional and non conventional optimization tools such as LR and ABC are applied. This methodology is formulated mathematically based on installation cost of the FACTS device and active power generation cost. The capability of IPFC to control the real and reactive power simultaneously in multiple transmission lines is exploited here. Apart from locating the optimal position of IPFC, this algorithm is used to find the optimal dispatch of the generating units and the optimal value of IPFC parameters. IPFC is modeled using Power Injection (PI) model and incorporated into the problem formulation. This proposed method is compared with that of conventional LR method by validating on standard test systems like 5-bus, IEEE 30-bus and IEEE 118-bus systems. A detailed discussion on power flow and voltage profile improvement is carried out which reveals that incorporating IPFC into power system network in its optimal location significantly enhance the load margin as well as the reliability of the system.

Opis:
There is currently a significant focus on using boundary layer control (BLC) approach for controlling the flow around bodies, especially the foil sections. In marine engineering this is done with the hope of increasing the lift – to – drag ratio and efficiency of the hydrofoils. In this paper, effects of the method on hydrodynamic characteristics and tip vortex formation of a hydrofoil are studied. Steady water injection at the tip of the hydrofoil is simulated in different conditions by using ANSYS-CFX commercial software. Validity of the proposed simulations is verified by comparing the obtained results against available experimental data. Effects of the injection on the lift, drag, and lift – to – drag ratio are studied and the ranges within which the injection has the most positive or negative effects, are determined. Furthermore, flow pattern and pressure variation are studied upon the water injection to determine the most positive and negative case and to ascertain the main reasons triggering these phenomena.
