Reduction of Nozzle Tip Breakage in Heavy Duty Diesel Vehicles using Problem Solving Approach

Abstract

On field sustainability of Engine components determines the efficiency and performance characteristics of the vehicles. Problem is injector nozzle tip breakage at lower load cycles in case of heavy duty diesel engines. Application of Injectors being Trucks, Tractor Trailers, Tippers, Buses etc. Project is carried out at Bosch Ltd. Bangalore. Bosch Production System?s (BPS) Problem Solving Approach is used to find out the root cause of the problem. Moving parts of the injector mainly influences the injection timing, and hence the combustion and emission characteristics.
