Effect of Injector cone angle and NTP on performance and emissions of CRDe engine for BS6 compliance 2019-28-0108

The quality of combustion is affected by factors like engine components design, combustion chamber design, EGR, after treatments systems, engine operating parameters etc. The role of fuel injector is crucial on achieving the desired engine performance and emissions. Efficient combustion depends on the quantity of fuel injected, penetration, atomization and optimum injection timing. The nozzle through flow, cone angle, no of sprays and nozzle tip penetration are the factors which decide the selection of perfect injector for an engine. This paper focuses on the selection of the best fit injector suiting the BS6 application on evaluating the performance and emission characteristics. Injectors used were with varying cone angles and NTP which was varied by changing the sealing washer thickness. With all the above injector configuration, the performance and emission were thoroughly analysed at each level. Final configuration was selected based on the Power & Torque, Fuel consumption, smoke, exhaust temperatures.
