Development of Rotary Diesel Fuel Injection System for a Tractor Engine to Meet Tier-I Emission Norms 2003-26-0007
This paper deals with the development of rotary fuel injection pump for a direct injection tractor engine to meet US Tier - I emission norms. The development involves optimisation of injection parameters such as injection rate, timing, injection pressures, nozzle hole geometry and use of in-built features provided by rotary pump technology. The influence of above injection parameters on engine performance and results obtained are discussed in this paper. The optimised rotary fuel injection system meets comfortably the US Tier - I emission norms.
