摘要： A common rail electronic control injection system which uses a DME or a low-viscosity fuel similar with DME to inject into a combustion engine, includes a fuel container, a common rail tube, a high-pressure tube, an electronic control injector, an electronic control unit, a high-pressure pump, a working medium case, a reversing component, and a pressure convertor, wherein the pressure convertor includes at least two working components, each working component is divided into a fuel chamber and a working medium chamber by an dividing element, the dividing element can freely deform or move between the fuel chamber and the working medium chamber by pressure effect. The invention avoids the sealing and abrasion problem in the plunger matching portions which is caused by the low-viscosity fuel so as to greatly improve the lifetime and reliability of system.

摘要： The present invention relates to a common rail electronic control injector, which belongs to the electronic control fuel injection system technology. The injector includes an oil inlet joint, an oil inlet located at outside the oil inlet joint, an electromagnet device, a nozzle body, a needle valve, a valve seat and spray holes, wherein the electromagnet device includes a static core, an armature and a coil, wherein a working gap between the static core and the armature is H, the armature is moveably connected with the needle valve along an axial direction. The present invention further includes a compression spring applying a force to the needle valve, a force mechanism applying a force to the armature, and a block mechanism providing an axial anti-thrust while the armature is reset. The present invention has advantages of lower manufacturing cost, better reliability and smaller driving energy.
