Maximum Pressure in Diesel Injection Systems with New Materials

Pressures in diesel injection systems are continuing to increase. Higher injection pressures are required due to finer atomization of the fuel during injection, an increasing number of partial injections during the entire injection cycle as well as other aspects relating to injection technology. Fuel-carrying components demonstrate maximum stresses at the bore intersections. Materials are required here which can withstand the high pulsating loads. Hirschvogel parts are represented in at least three projects in which a 2,500 bar nominal injection pressure is being used in series. Through new material developments as well as the possibility of carrying out analyses using two scanning electron microscopes (one of which is a field emitter), and on the basis of long-standing experience in large series production, we are able to offer our customers new solutions and the necessary support in selecting materials to bring even more sophisticated components onto the road.
