Method and Apparatus to process Pressure Interactions between Succesive Injections in a Common Rail Fuel Injection System

The process involves decreasing frequency of pressure wave by extending length of a supply pipe (40) connecting a common manifold (50) to every injector (60). The supply pipe is in spiral form and is effectuated by meshing on a bar or internal tube covered by an external tube by tight adjustment. An additional volume to attain a certain effect of emptiness is used for every supply pipe. An independent claim is also included for an injection system with a common manifold of fuel supply for motor vehicle.
