In this study, the effect of sintering temperature on the physical, chemical and tribological effects of sintered automotive friction materials was investigated. Using the powder metallurgy method, 3 different samples were produced with the codes A1, A6 and A11. Mixing, pressing and sintering processes were applied respectively as production steps. Mixing time is 90 minutes, speed is 15 rpm. The pressing pressure is 250 MPa and the duration is 1 min. The sintering temperature was 800 °C and the sintering time was 1, 6 and 11 hours, respectively. The sintering process was carried out in the sintering mold using Argon gas. As the sintering time increased, it was observed that there was an increase in the time-dependent friction coefficients of the samples. Increasing the sintering time also increased the density of the samples. As the sintering time increased, the gap in the sample decreased, as it provided better bonding of the dustsers.

This paper presents a parametric study and comparison of turbocompound gasoline engine with diesel engine based on analysis done in previous papers. Turbocompounding is an important technique to recover waste heat from engine exhaust and reduce CO_2 emission, improving fuel economy. By the time detected one of the biggest problems for IC engines is pollution. Downsizing studies are popular at the industry for the moments to get emission and fuel consumption decreased. Even if the racing industry gets involved in this trend having more efficient and more green racing vehicles is quite important for saving environment. Powertrain works with supercharged internal combustion engine by co-operation of two electric motors MGU-H (Motor-Generator Unit-Heat) and MGU-K (Motor-Generator Unit-Kinetic). It is also seen in passenger, light and heavy commercial vehicles with diesel engines using turbocompounding technology to decrease the pollution. The present paper compares the outcomes which were shown in previous papers and demonstrate the better performance in terms of greenhouse effect and pollution as well as engine power generation performance.

Scientists continue to work in order to obtain clean and efficient energy in a sustainable and economical way. Biodiesel is an important research topic not only because it is a renewable energy source, but also because it is an environmentally friendly fuel that can be produced as efficiently as petroleum-derived fuels. The raw materials used are as important as the production parameters in the production of biodiesel fuels. Hemp is not a widely cultivated plant because its cultivation is subject to government control. However, by breeding, the production of species containing low amount of stimulant and high amount of seed and fiber can be realized. In case of an efficient fuel production in compliance with the determined standards, the hemp plant can be accepted as a raw material that can also be evaluated in the field of energy. In order to guide the studies to be carried out for this purpose, in this study, the conformity of the fuel obtained by producing biodiesel from hemp seed oil to the standards was examined. As a result of the fuel analysis, it has been seen that the fuel properties of the produced hemp biodiesel are largely compatible with the TS EN 14214 standards. The results obtained provided a sufficient starting point for the development of the study.
科学家们继续努力，以便以可持续和经济的方式获得清洁和高效的能源。生物柴油是一个重要的研究课题，不仅因为它是一种可再生能源，而且因为它是一种环境友好的燃料，可以像石油衍生燃料一样高效地生产。在生物柴油的生产中，原料的选择与生产参数一样重要。大麻不是一种广泛种植的植物，因为它的种植受到政府的控制。然而，通过育种，可以生产出含有少量兴奋剂和大量种子和纤维的品种。在符合确定标准的高效燃料生产的情况下，大麻植物可以被接受为原材料，也可以在能源领域进行评估。为了指导今后开展的相关研究，本研究对用大麻籽油生产生物柴油所得燃料的符合性进行了检验。燃料分析的结果表明，生产的大麻生物柴油的燃料性能在很大程度上符合TS EN 14214标准。所得结果为研究的开展提供了充分的出发点。

In this study, the long-term endurance tests were carried out in a diesel engine that used diesel and 90% diesel + 10% bioethanol fuels. The spray and temperature distributions of two different fuels in the AVL FIRE program also were examined. Tribological and morphological analysis of piston rings were investigated in a single-cylinder direct injection diesel engine using two different fuel types. The test engine used two different fuel types and was operated for approximately 110 hours under part engine load. Renewed rings in each fuelled engine operation were analyzed at Energy Dispersive X-ray Spectroscopy (EDX) and Scanning Electron Microscope (SEM). Results were also compared with the non-worked piston ring. Analysis results saw that abrasive wear was more intense on the first rings at both fuel types. Examining the effect of biofuels on engine wears, short wear lines were found at engine rings using diesel/bioethanol blend fuel compared to diesel fuel. It was being determined that this situation was a result of combustion parameters (such as pressure, and temperature) created with the different fuels used in diesel engines. As a result, that bioethanol has a content of low carbon (C) compared to diesel fuel, making a positive contribution to the reduction of ring wear.

Traffic accidents continue to be a significant issue in modern society. Accidents usually happen on dark, mountainous, narrow, steep and curved roadways. One of the primary causes of such accidents is the drivers’ weak sight brought on by the headlights of moving vehicles. In this study, a dynamic headlight model was designed using camera supported machine learning algorithms to improve the drivers’ vision during night drive. In this design, the issues of enabling a lighting field supported by image processing programmed with machine learning, dynamic adjustment of the high beam headlights’ LED cells in response to the vehicle approaching from the opposite direction, traffic-sign recognition system, lane-keeping system, and automatic adjustment of headlight angles were addressed. In this direction, a novel dynamic headlight model that will reduce the risk of accidents caused by lighting was presented, and its analyses were performed.

Today, backhoe loader machines are widely used in different areas such as the construction industry, mining industry, arrangement of agricultural areas, maintenance and repair activities in settlements. One of the most important reasons why the usage areas of these machines are so wide is that they have a design that includes both excavation and loading capabilities. With different attachments attached to both the backhoe and loader mechanisms, backhoe loader machines can have a wide variety of operating capabilities. In this study, weight reduction of the backhoe arm of a backhoe loader is carried out. The results obtained from the analyzes made on the existing design gave direction to the weight reduction process. While creating alternative models within the scope of the weight reduction process, the structures of the connection points of the mechanisms, their positions and the distances between these connection points were kept constant, allowing all alternative designs to be mounted on the machine without the need to make any changes on the existing machine. With this weight reduction study, it is aimed to reduce the weight and fuel consumption of the machine as well as to increase the operating efficiency of the machine. Structural analyzes were made on the optimum structure obtained, and it was examined whether the new model was suitable for working conditions in terms of strength. The current design and the optimized design are compared in terms of strength and operating performance.

Direct injection on the Wankel engines has been practiced since the 1970’s. By applying direct injection in the Wankel engine, the specific fuel consumption and HC emissions, which are seen as disadvantages for this engine, might be reduced and the mixture formation is improved. In order to obtain a better mixture formation, the fuel injector must be located in a proper place and a correct direction. In addition, the most suitable injector for the engine structure should be selected. In this study, direct injection was applied for the RENESIS 13B Wankel engine and injector selection for the engine and the location of the injector on the housing were examined. In addition, the diameter of orifice and flow rate characteristics of the injector were investigated. According to the results, two types of injectors were selected. These injectors were called as low speed and high speed. An injector with a narrow nozzle angle (<30°) was used to deliver the fuel to the leading of the chamber, and the fuel injected after the intake ports closed. The orifice diameters of low-speed and high- speed injectors were measured 0.33 and 0.45 mm, respectively. In addition, both injectors have low speed rates when injection duration was below 2 ms. This flow rate was increased by providing high voltage.

An emission reduction method has been analyzed for Liquid Hydrogen (LH2) powered Fuel Cell Vehicles (FCVs) using GREET software in this study. In the analysis, cooling rates and Coefficient of Performance (COP) values of the proposed system have been calculated for FCVs that considered. Average reductions of the years 2010, 2020, 2030, 2040, and 2050 in emissions for the use of Auxiliary Air Condition (AAC) system in the FCVs are analyzed in g/year for Volatile Organic Compounds (VOC), Carbon Monoxide (CO), Nitrogen Oxides (NOx), Particulate Matters (PM10 & PM2.5), and Sulfur Oxides (SOx). Average reduction in Carbon Dioxide (CO2) emission is calculated and given in kg/year. All the emissions decrease in significant proportions due to the reduction in fuel consumption by less usage of the main AC system of the vehicles.

Measuring the level and accurate transmission of the amount of fuel in vehicle fuel tanks are important in many ways. In vehicle warehouse designs, very different geometric shapes are encountered. Vehicle geometry and equipment placement cause warehouses to be produced in very different geometries. It is very important that information about the amount of fuel is transmitted to the driver in the most accurate way so that the driving safety and the car can travel safe distances. Shaking the fuel in the tank on a flat road, slope or off-road conditions may affect the display of the correct amount of fuel. In the study, the maximum and minimum production tolerance and geometry of the vehicle tanks, known as the mathematical model, the turbulence caused by acceleration of the float fuel measurement system in contact with the liquid placed in the tank, as well as the accuracy of the Up/Down movement of the level measurement float and the measurement of the fuel level as a result of the turbulence, were examined. The study focused on the oscillation of the measuring part on the float and the preventive geometries.
