SWIRL DIRECT COMMON RAIL INJECTION SYSTEM: REMARKABLE DIMENSION IN DIESEL FUEL TECHNOLOGY (Pages : 39 - 44)

With the increasing demand of diesel internal combustion engine worldwide, the need for fuel economy resulted in the development of diesel fuel injection system take place in modern research. The latest common rail injection (CRI) mechanisms are making a combination of the high performance of the petrol engines and superior fuel economy characteristics of diesel engines. A lot of studies have been conducted on the improved technology, and it is now definite that the advantages of CRI systems are undeniable. Its outstanding advantages in technical, economical, and environmental fields, Swirl direct CRI systems are superior to previous engine technologies. This system is a modern variant of direct fuel injection system for internal combustion engines. In diesel engines, a high pressure fuel rail feeding individual solenoid valves is featured. As opposed to low pressure fuel pump feeding unit injectors or high pressure fuel line to mechanical valves controlled by cams on the camshaft; this system is efficient due to variant of direct fuel injection system. The key component of the system is the solenoid valve controlled injector and the development of the injector nozzle with several mechanical modifications (especially helical gear type swirl spray unit and injector cap) results to deliver the outstanding idle quality, unparalleled flow consistency and unrivaled durability essential for high performance fuel injection. The technology ensures the injection spray patterns and mixing of fuels with the intake air at a good ratio which results good combustion inside the engine that leads to improvement in engine efficiency, fuel economy etc. The result shows, at high pressure the swirl nozzle refers to maximum volume of fuel consumption, which is important for burning inside the engine that ensures improvement of driving performance and higher fuel economy which is important for efficient common rail injection technology.Download
