Interface Optimization of Welded Fuel Accumulator of Common Rail System

This master’s thesis is aimed to sphere of injection system for diesel engines. The main task of thesis was to invent new concept for high pressure interface of laser welded fuel accumulator, that would able to endure pressure 2000 bars and higher. Also, it would be applicable to serial production. Thesis includes description of diesel system by Bosch, making of design proposals in ProEngineer program and making of stress analyses for some particular elements in Ansys. Whole the work was passed in conjunction with Bosch Diesel development department
