Seven problems occur about common rail diesel engine nozzle during use

Seven common rail diesel engine nozzle problems in the course of the most common reasons :
♦ Wear : spray nozzle and the surface of the material within the flow channel is gradually falling, thereby affecting the flow rate, pressure and spray pattern .
♦ Corrosion: Spray liquid or environmental effects due to chemical corrosion damage references nozzle material.
♦ Obstruction : dirt or other impurities blocking the nozzle inside the mouth, thus limiting traffic and interference spray pattern .
♦ Bonding: nozzle inside the mouth or on the outside edge of the material, splash, mist or chemical effect due to the accumulation of liquid evaporation and condensation caused by a layer of dry solidified layer, hindering the nozzle orifice or the flow channel.
♦ Temperature damage: a harmful influence caused by the heat of the nozzle material for the design of non- use of the high temperature produced .
♦ Error Installation: When installing the axis deviation, excessive tightening or change the installation location, these problems can lead to the generation of leakage, and adversely affect spray performance .
♦ Accidental injury : the installation and cleaning due to the incorrect application of tools and a nozzle causing unintended damage.
