Fuel Spray Characteristics and Performance Analysis of a Swirl Direct Common Rail Injector (SDCRi)

다국어 초록 (Multilingual Abstract)

Common rail injection system is playing an important role in internal combustion engine technology. The technology is technically acceptable, environmentally-friendly and economically viable. This system is efficient due to variant of direct fuel injection system. Common rail fuel injection systems for internal combustion diesel engines are designed to perform the task to secure acceptable fuel spray characteristics during the combustion process at all load conditions. It’s improved driving performance and higher fuel economy results the efficient injection technology as well as it satisfy the clean environment requirement by reducing the emissions and operating engine noise.
Recent advancements and advantages of common rail injection technology are undeniable superior to previous injection technologies. Under these circumstances, the swirl direct common rail injector for internal combustion diesel engine developed. In this regard, the design of the injector nozzle, helical gear type swirl spray unit and injector cap has taken into consideration. Application of these attachments follows to deliver the outstanding idle quality, unparalleled flow consistency and unrivaled durability essential for high performance electronic fuel injection.
The outcome of the swirl direct common rail injection is the swirl spray characteristics that results excellent mixing with the intake air followed by uniform combustion which is finally leads to lower exhaust emission and improvement in engine efficiency. The common rail injection system features high pressure fuel rail feeding individual solenoid valves as opposed to low-pressure fuel pump feeding unit injectors, or high-pressure fuel line to mechanical valves controlled by cams on the camshaft. Therefore, at high pressure the swirl direct common rail injection system results maximum volume of fuel consumption, which is important for burning inside the engine. Moreover, the injection count is take suitable timing which ensures maximum possible spray of injection at a minimum time with respective to required rpm and motor power.
