Opis:: The experimental study was conducted to investigate the effects of different opening ranges of waste gate of a turbocharged medium displacement spark ignition engine on improving work parameters such as exhaust emission, torque characteristics and fuel consumption. The object of the experimental tests was an engine with modified intake and exhaust manifolds. The intake and exhaust manifold modification included only implementation of turbocharger with the variable geometry turbine. The values of boost pressure were controlled by the system with waste gate valves with a changeable characteristic and a control valve. Work parameters of waste-gate valves have been selected experimentally. Boost pressure had to be reduced to 1.3 and to 1.5 bar in the range of medium values of throttle opening. The system with waste-gate allowed to increase significantly the torque value at low engine speed range as well as to reduce the boost pressure at high engine speed range for throttle opening values above 50%. In total range engine work, emission of particular exhaust gas components did not exceed the values of the emission suitable for normally aspirated engine. It provided the stable engine 's running in all conditions including variable engine speed and in the whole range of throttle opening angle with restricted fuel consumption. The application of changeable characteristics in the waste gate valve which reduces the charging pressure by controlling characteristics variable of the valve depending on the engine work parameters was controlled by electronic system. The controlled system allows improving parameters of engine performance in wide range of engine's rotation speed.

Opis:: The purpose of the investigation was the application of two turbochargers system in spark ignition engine and determining turbochargers' work parameters depending on throttle opening and engine's rotation speed. System with small turbocharger and larger variable geometry turbocharger in parallel connection (three-stage turbocharging) was examined. The engine used during the investigation was 1300 cm displacement SI engine with modified intake and exhaust manifolds. Intake and exhaust manifold modification including only implementation of turbochargers and sensors was done for experimental purposes. Specific values of maximum boost pressure were obtained by introducing a waste gate valve system with appropriate characteristic. Proper choice concerning work parameters of the charging system allows to improve torque characteristic in wide range of engine's rotation speed. The system with additional small turbocharger allowed to increase torque value in low engine's speed range as well as to increase boost pressure in high engine's speed range for throttle opening angle values above 50 %. In medium engine's speed range the best results were given by variable geometry turbocharger. The two turbochargers system and values of maximum boost pressure were controlled by the system with two waste gate valves. Improving total efficiency was obtained in medium engine's speed range. The application of two turbochargers system as modification of naturally aspirated spark ignition engine allows to improve torque flexibility rate. There is a possibility to apply the charging system with two turbochargers, with boost pressure control system, in already existing, naturally aspirated engine without decreasing compression ratio and modifying engine's control system.

Opis:: Synthetic gas (syngas) produced form waste organic matter may be used as a fuel for internal combustion engines. Possibilities of syngas application as an independent IC engine energy carrier are limited. Designed system of energy conversion from waste to electricity is expected to produce gas consists mainly carbon monoxide, methane, hydrogen and carbon dioxide. Based on theoretical study and own research, as the main factors which impact on floating syngas composition the quality of input substance, process temperature and gasifying medium application were identified. The fluctuation of syngas composition contributes important challenge in aspect of energetic efficiency and mechanical durability of generator system. The researches were provided on research test bed, which enables pressure distribution measurement in the combustion chamber (for various mixture of synthetic gases) and correction of ignition timing. The results of the researches indicate that proper correction of the ignition advance allows syngas mixtures combustion in wide range of their composition.

Opis:: Today, more and more attention is paid to search for alternative fuels, which would be not only environmentally friendly, but also cost-competitive to petroleum fuels. In the recent years much attention is paid to investigations at adaptation of combustion engine to run on bio-fuels. Results of the investigations show, that methyl and ethyl alcohols could belong to one from the most promising and future bio-fuels, being a serious alternative to petroleum fuels. Interest in these fuels comprises such areas as exploration of raw materials to production of the alcohols, development of technology of their production, especially 2nd generation of ethyl alcohol, special fuelling and control systems, design changes of the engines fuelled with alcohols. In the present paper are shown test results of Fiat 1.3 Multipoint engine fuelled in dual fuel system with methanol and gasoline. In this engine one assembled prototype fuel supply system with duplex injectors on each cylinder, to injection of methanol and gasoline. Implemented system enables fuelling with gasoline only, with methanol only, or simultaneously with gasoline and methanol with any fraction of the methanol. Change of fuelling system and change of methanol fraction can be accomplished in course of engine operation. Performed investigations showed advantageous effect of the methanol on toxicity of exhaust gases. One confirmed reduction of emissions of hydrocarbons, nitrogen oxide and carbon dioxide. The biggest changes in the concentration occurred in case of fuelling with the methanol only, and amounted to: 2-3 times reduction of the THC, reduction of NOx with 40-60%. Differences in concentration of NOx increased together with growth of engine load, and hence, they concern such areas of engine operation, where the biggest quantities of the NOx are emitted. In case of dual fuel feeding, effect of reduction of concentration of the components discussed here decreases according to reduced fraction of the methanol. Changes in the emissions discussed here are obtained with maintained engine performance and growth of overall efficiency of the engine. Implemented system eliminates problems of stratification of methanol-gasoline mixture in low temperatures and in presence of water. The system can be adapted to any liquid fuels.

Opis:: This paper describes the possibility of controlling injection and ignition parameters of a spark-ignition engine performed with the author's controller. The modification of output signals according to given parameters of the interface is shown in this article. Simulations, supported by oscilloscope graphs, were performed using the controller designed to work with four-cylinder spark-ignition engine. This device allows modifying the ignition and injection parameters depending on the values entered in the author's interface on the PC. This interface enables a serial transmission through a RS 232 serial port and sending data to the microcontroller. The controller allows for a measurement of the values of the sensors and a generation of output signals for the actuators. The simulation done in this work involves the modification of injection and ignition angle parameters: ignition angle of advance (KWZ), injection angle of advance (KWW) and time parameters: time of injection (KW), time of ignition (KZ). Also shown in this article are possibilities of adapting the controller of the spark-ignition engine to a simultaneous, batched and sequential injection mode.

Opis:: This article reports the results of a study into operating parameters of a system consisting of an SI engine and a powertrain in a Fiat Panda passenger car in the conditions of a variable load. The analysis was primarily concerned with the variability of fuel consumption resulting of the changing load applied to the driving wheels in the conditions of a test performed on chassis dynamometer for manual and automatic controlled transmission gear change The test bench included a dedicated driving cycle, which was developed as cycle with periodically changed constant linear speed of the car every 10 km/h. According to the vehicle set speed, the load on its wheels was determined by the basic resistance as rolling resistance, air resistance and resistance corresponding to road inclination. Each period of a drive cycle corresponding to steady state driving gave the average instantaneous values of drive system performance indicators. The waveforms of these indicators were recorded and then averaged and presented as representative points of the powertrain system that were analysed. The focus of the study involved the identification of the points characterized with the minimum specific fuel consumption and impact of type of powertrain control on emission of CO2 from passenger car SI engines.

Opis:: Przedstawiono wyniki własnych badań silnikowych nad zastosowaniem komponentów depolimerowych jako paliwa do silnika o ZI. W wyniku przeprowadzonych badań stwierdzono, że ze względów eksploatacyjnych najlepszym komponentem paliwowym jest dodatek 10% benzyny X i 20% benzyny Y z DTS (depolimeryzacji tworzyw sztucznych). Stwierdzono, że 20% dodatek benzyn X i Y z DTS jest wielkością graniczną, powyżej której efekty w ograniczaniu emisji CO i HC nie rekompensują wzrostu emisji NOx i wyraźnego pogorszenia parametrów eksploatacyjnych pracy silnika.
Research results of the application of depolymerization components as a fuel to the spark ignition engine are presented. The research determined that the best fuel components for the operational conditions are the 10% gasoline X additive and the 20% gasoline Y additive with PD (Plastics Depolymerization). The 20% value gasoline X and Y additives with PD is the limiting value. Below this value, the effects in reducing CO and HC did not compensate for the increase NOx emissions and there was a clear deterioration in the operational performance of the engine.

End Gas Region
Opis:: It is important to increase thermal efficiency in a spark-ignition engine for reducing carbon dioxide gas in exhaust emissions. One of the solutions is to increase the compression ratio of the engine. Then, knock is a barrier in increasing in compression ratio because of higher pressure and unburned gas temperature in the end gas region. Therefore, there have been many studies on knock. However, there was an interesting phenomenon under some conditions in a gas engine. There is no pressure oscillation in the end stage of combustion and rate of heat release increased. It is considered that the auto-ignition in the end gas region occurs without knock. In this study, the combustion behavior in the end gas region was visualized with an ultra-high-speed camera. In normal combustion case, the flame propagates in the end gas region. In the knock case, the auto-ignited part burns suddenly and leads pressure oscillation. Under the critical conditions, some shows knock and some shows normal flame propagation. However, in some cases, even if auto-ignition occurs, pressure wave is not produced. Then there is no pressure oscillation, that is, mild auto-ignition without knock can be confirmed. And the rate of heat release shows two peaks. The first peak is due to flame propagation and the second peak is due to auto-ignition in the end gas region. The combustion near the end stage become short and thermal efficiency is expected to be increased because of increase in degree of constant-volume.

Opis:: Different optical techniques were applied to describe the thermal and chemical processes that occur in a SI small engine from the ported fuel injection and in-cylinder mixture formation to the combustion process and the exhaust emission. In PFI SI engines, the atomized fuel is sprayed towards the intake valves, where it may evaporate, puddle or rebound. Furthermore, a portion of the fuel may flow directly into the cylinder or impinge upon the port walls. These phenomena occur in varying degrees and depend upon the engine design, injector location and engine operation. Potentially the fuel can enter the cylinder in a poorly atomized state, leading to an increased unburned hydrocarbon emissions. This is particularly true during cold operation, when evaporation is low. In the small-motorcycle and scooter engines the fuel injection occurs in smaller intake manifold than light-duty vehicle engines, increasing the criticism of the fuel-wall interaction. The experimental investigations were performed in a single cylinder engine constituted by an elongated optically accessible piston and equipped with the head and injection system of a reference 4-stroke engine for small vehicles. High spatial resolution imaging was used to characterize the fuel injection phase. The cycle resolved visualization was performed to follow the flame propagation from the intake spark ignition to the exhaust phase. Natural emission spectroscopy measurements were applied in the ultraviolet-visible wavelength range to identify the chemical species that are markers of the combustion process and to follow the formation of pollutants.

Opis:: In the paper are presented comparative tests of combustion of gasoline and combustion of methanol in spark ignition engine of the Fiat 1100 MPI type. The engine was equipped with a prototype suction manifold with duplex injectors on each cylinder. Implemented system enabled dual fuel operation of the engine with any fraction of the alcohol. Engine performance and start-up capabilities were the same like in case of the operation on gasoline only. Type and parameters of the fuel supply can be changed in any time during operation of the engine. The study dealt with comparison of a selected parameters used to assessment of combustion of the fuels: pressure of the working medium p, rate of pressure rise dp/d, heat release rate dQ/d, temperature of the working medium, and combustion angle. The investigations pointed at considerable differences in run of combustion of the gasoline and combustion of the methanol, as autonomous fuels. Moreover, addition of methanol to gasoline results in considerable differences in combustion process, comparing to combustion of gasoline mixtures. The combustion goes on more dynamically, especially during initial phase of the process, while total time of the combustion is shorter. Effects of these changes are: higher maximal pressures, faster rates of pressure growth and heat release. Extent of change of combustion parameters depends on methanol fraction in total dose of the fuel supplied to the engine. Addition of the methanol effects in growth of general efficiency of the engine, which increases together with growth of methanol fraction and engine load. Absolute growth of the efficiency amounted to 2-5%, while relative growth amounted to 6-16%. Such significant growth of the efficiency should lead to reduction of energy consumption during engine operation.

Opis:: The theoretical analysis of the SI engine load adjustment has been presented. The load especially in SI engine is highly dependent on the process of charge exchange. This process has significant impact on the effectiveness of an engine work because it is connected with the necessity of overcoming the flow resistance, then with the necessity of doing a work, so-called the charge exchange work. The flow resistance caused by throttling valve is especially high during part load operation. The open theoretical cycle has been assumed as a model of processes proceeding in the engine. Using fully variable inlet and exhaust valves timing the cycle can be realized e.g. according to two systems: system with early inlet valve closing (EIVC) and system with early exhaust valve closing (EEVC). Both systems have been analysed individually and comparatively with the open Seiliger-Sabathe cycle, which is theoretical cycle for the classical throttle governing of an engine load. Benefits resulting from application of the systems with independent inlet and exhaust valves control have been assessed on the basis of the selected parameters: a fuel dose, a cycle work, a charge exchange work and a cycle efficiency. The use of the analysed systems to governing of the SI engine load will enable to eliminate a throttling valve from inlet system and reduce the charge exchange work, especially within the range of part load operation. Decrease of the charge exchange work leads to increase of the internal and effective works, which results in increase of the effective efficiency of the spark ignition engine. Additionally, the EEVC enables realization of the internal EGR.
