Abstract:
Electrolysis is the most common method used to split H2 from water and currently, 12-15% of hydrogen production globally source is presented by electrolysis. Hydroxy Gas (HHO) is a trademark and comes from the separation of water molecules H-OH that contains (theoretically) 66% H2 and 33% O2. It has high calorific value and 1 kg of HHO, is three times as potent as gasoline and eight times as potent as diesel. Also achieving of HHO gas under water electrolysis, several item affected the end product. This affected the efficiency of the HHO generators. Electrolysis uses an electrical current to split water into hydrogen at the cathode (+) and oxygen at the anode (–). Steam electrolysis uses heat, instead of electricity, to provide some of the energy needed to split water and can make the process more energy efficient. In this study, HHO is mixed with air and gasoline in inlet manifold in a gasoline engine and HHO is mixed with air and natural gas during induction stoke and diesel fuel is injected into the cylinder during injection period in a pilot injection diesel engine to measure engine performance and exhaust emission parameters. HHO gas addition to the fossil fuels (gasoline, diesel fuel and natural gas) improved engine performance parameters (power, torque and specific fuel consumption) and reduced exhaust emission parameters. The average power increment in test engines during experiments is bigger than the electrical power consumed and fuel economy obtained with the aid of HHO system as well. This indicates that HHO system is efficient.

Abstract:
This speech is related to our Joint Research and Development Project (Project No.114M833) signed between 2510-(TÜBÄ°TAK) The Scientific and Technological Research Council of Turkey and (MHESR) The Ministry of Higher Education Scientific Research of Tunisia titled “Investigation of Piston Rings by New Developed Graphene Coating Method for Reducing Wear and Friction in Internal Combustion Engines”. I will talk about some chronological order of my big tribological work since 1999 up to nowadays on crankcase oil additives, lubrication-friction-wear with several coatings (such as zinc phosphate, transferring synthesized method of graphene with support of GrafenBiotech Ltd. i.e.) of piston rings against cylinder liner in reciprocating motion within Tribotest Rigs and I.C. Engine Experiments. Colorful protective additive’s layers formed on the rubbed surfaces under boundary lubrication conditions during experiments where the formal test conditions were applied using real engine material of piston rings and cylinder liner. Wear tracks, protective layers of additives were examined using digital optical, electron microscopy within X-ray diffraction analysis where additive layers were detected in nanoscale dimension.

Title: Effect of cooling gallery on the piston temperature in a gasoline direction injection engine
Time : 14:00-14:30
Biography:
Sangwook Han has completed his PhD from Korea Advanced Institute of Science and Technology. He is a Senior Researcher in the Clean Engine System R&D Center of Korea Automotive Technology Institute, Korea. His research interests are in the engine combustion, vehicle thermal management system and automobile parts development for the improvement of fuel economy.
Abstract:
Significant efforts have been devoted to developing gasoline direct injection (GDI) engine technologies to meet the stringent emission legislation. From the combustion point of view, combustion pressure is getting higher with higher injection pressure and boosting pressure, which enhances the combustion process and thus reduces the emissions. This issue requires reinforcement of the piston as well as improvement of cooling performance in the piston. The objective of this study was to investigate the effect of cooling gallery on the piston temperature in a GDI engine. Prior to the engine experiment, parametric study on the oil jet was performed in the test bench. In addition, oil targeting was optimized for the insurance of sufficient oil flow rate in the cooling gallery. This was realized by optical piston and modified cylinder block. Two types of pistons, which are with and without cooling gallery, were developed by Dongsuh Federal-Mogul in Korea. Furthermore, the research engine was modified to install the oil jet in the cylinder block and inject the oil into the cooling gallery in the piston. The developed pistons were applied and evaluated in a GDI engine. The piston temperature was measured by templug which is screw-type steel and is sensitive to temperature. It was confirmed that the cooling gallery played an important role in determining the piston temperature. The piston with the cooling gallery resulted in significantly lower temperature. It is believed that the optimization for the location and shape of cooling gallery should be needed for better cooling performance.

Abstract:
Structural transfer path analysis describes the total interior sound pressure level as a vector sum of individual contributions from the powertrain force inputs entering the unibody over the engine and exhaust mounts. In this work, a hybrid transfer path analysis method that utilizes computational and experimental studies is proposed. Computational transfer path analysis is important to achieve modification studies, but the frequency response functions obtained do not contain the damping information. On the other hand, complex frequency response functions measured during the experimentation have the damping information embedded in. However, it is possible to separate damping form the frequency response functions measured. These damping free functions are called as normal frequency response functions. Correlation is made between the undamped computational model of the structure and normal frequency response functions derived from experimental transfer path analysis study. The proposed method essentially makes use of the viscous damping identified in the experimental step. Viscous damping data are computed separately and imposed on the final computational model. In this talk, important advantages of the method and a reference application will be presented. Results of the application demonstrate that the method proposed works well with real problems.

Abstract:
The automobile industry significantly contributes to the overall economic performance of the Czech Republic and in the recent years with growing total assets, a number of employees and sales, especially from export, the share of the automobile industry in manufacturing industry further increases. Manufacture of motor vehicles (except motorcycles), trailers and semi-trailers represent the core automotive industry, i.e. vehicle and parts makers in the Czech Republic. It refers particularly to manufacture of motor vehicles; manufacture of bodies for motor vehicles, manufacture of trailers and semi-trailers, and manufacture of parts and accessories for motor vehicles. The survey refers about the Czech automotive industry financial aspects results supported inter alia by financial statements and ratios analyses, and provides an overall assessment of the financial situation and insights into this business. Related important issues as if the Czech automotive industry has been severely hit by the crisis since mid-2008 investigating the car sales, or if the Czech government has been supported the automobile industry by scrapping schemes are considered. Finally, assessment of the current economic importance of the Czech car market, of its size share in the overall size of OECD economies in terms of value added, employment and export and specific features of the Czech automobile industry are presented.
