Ensuring smooth and efficient processes inside the engine
Nozzle needles in diesel engine common rail systems are only a few millimeters in size, but they play a major role in ensuring smooth and efficient engine processes. Vitesco Technologies, the drive division of Continental, has these needles coated with BALINIT DLC. But how do you ensure that the coating quality of these small components is just right when there are several million of them?
Vehicle manufacturers and end customers expect modern engines to burn fuel as efficiently as possible — for performance, cost and environmental reasons. Only 43 mm long and just 4 mm wide, nozzle needles play an essential role in achieving this, as they ensure the correct injection of fuel from the injector into the combustion chamber. Optimal fuel atomization, which is essential for efficient fuel burning, is determined by a combination of the needle’s geometry and precise manufacturing, the nozzle body and accurate spatial positioning.
