An Electric Vehicle Conceptual Design Of The Chassis And Powertrain

Bu çalışmada, bilgisayar ortamında üç boyutlu olarak elektrikli bir aracın şasi ve aktarma organları tasarımı gerçekleştirilmiştir. Tasarım yapılırken günümüz elektrikli araçlarında kullanılan parçaların ve sistemlerinin konumları incelenerek ve yer tespiti yapılarak, tasarım bu tespitlere göre şekillendirilmiştir. Günümüzde gemi inşa, havacılık ve otomotiv sektöründe yaygın şekilde kullanılan profesyonel yazılımlar mevcuttur. Bunlar arasından seçilen uygun tasarım programı ile elektrikli aracın tasarımı gerçekleştirilirken günümüz koşullarında uygulanabilirliği düşünülmüş, daha basit ve kolay bir şekilde üretimi amaçlanmıştır. Bu maksatla yapılan çalışmada tasarlanan elektrikli bir aracın şasi, karoseri ve aktarma organları tertibatının yerleşimi ve konumlandırılması yapılmıştır. Bu tasarım bağlı olarak bir örnek analiz yapılmıştır. Bu konumlama ve örnek analiz bir sonraki araştırmalarda detaylandırılarak parçaların yapım resimleri çizilecek, analizleri yapılacak aşamaya getirilebilecektir.In this study, the chassis and power train design of electric vehicle was performed via three-dimensional computer program. During the design process, the system and components used in today's electric vehicle are observed and this design is formed according to this knowledge. Today, there are available professional software which is widely used in the aircraft industry, shipbuilding and automotive industry. Appropriate design program which is selected from these programs, in today's conditions performing the electric vehicle design considered applicability. İn the meantime the design was aimed to performed as easier producer. İn this search for a electric vehicle which made design chassis, body and components of powertrain arrangements was made. Case study of analysis is performed depends on design. This positioning and analysis of sample parts made in details in the next survey will be drawn pictures; analysis can support to next stages

An investigation of engine and fuel system performance in a diesel engine operating on waste cooking oil

Waste cooking oil (WCO) was experimentally examined to determine whether it can be used as an alternative fuel in a 3-cylinder, 4-stroke, direct injection, 48 kW power tractor engine. The test engine was operated under full load conditions using diesel fuel and waste vegetable oil from the 2400 to 1100 rpm and performance values were recorded. Tests were performed in two stages to evaluate the effect of the waste oils on the engine life cycle. When the test engine was operated with diesel fuel and waste cooking oil; engine torque decreased between at ratio of 0.09 % and 3% according to the engine speed. While no significant difference occurs in the diesel fuel tests at the end of 100 hours of operation, an important reduction was observed in the engine torque of the WCO engine between 4.21% and 14.48% according to the engine speed, and an increase in average smoke opacity ratio was also observed. In accordance with the results obtained from the studies, it was determined that the engine performance values of waste cooking oil show similar properties with diesel fuel, but in long-term usage, performance losses increased. In the SEM analysis performed on the fuel system, there were dark deposits at the nozzle tip and stem. According to an EDX analysis at the nozzle tips, the detected elements point to engine oil ash in the combustion chamber and show coking products (C and O). The other elements (Na, S, Ca, P, Cl, and K) point to used WCO.BOSCH Bursa Dizel Sistemle
