Ltd. and authorized authorized distributor of Cummins diesel engine: 18766824749Q Li Chang Q: 3247181663 common faults of engine and eliminate the mechanical failure series of common faults including mechanical fault and fault circuit. Mechanical fault injector including spool, injector clogging and leakage, when the injector appeared after the above failures will cause the failure of mechanical action, thus affecting the normal operation of the engine, the engine will sometimes appear serious fault. Injector needle valve clip injector is the signal sent by the engine control unit, solenoid injector electricity generated to drive the injector needle suction action. Because the adhesive clearance of needle valve and valve seat are remnants of the obstruction, resulting in the needle valve astringent does not open properly, thus affecting the normal fuel injection quantity. Injector needle valve clip after a fault occurs, the engine will be difficult to start, idle instability, poor acceleration and other symptoms. Main reasons of injector seizure is the use of inferior gasoline, because of poor in gasoline paraffin and pectin, which leads to the injector needle valve clip. Injector block fault can be divided into injector internal obstruction and injector head external blocking. Causes of injector internal blocking produced is clearance in gasoline mixed with impurities and dirt blocking the internal needle injector, the injector abnormal mechanical action. When the plug fault injector, the engine will be difficult to start, idle instability, poor acceleration and other symptoms, severe cases may even cause serious engine jitter, and caused the occurrence of abnormal wear of mechanical components. Injector leakage of fuel injector leakage is generally divided into two kinds of internal leakage and external leakage. Internal leakage of the fuel injector is mostly due to the early wear and tear in the use, resulting in the role of the system under the pressure of the continuous flow of fuel into the intake manifold. Injector external leakage occurred in the fuel injector and the oil rail connection, the sealing surface is sealed. If the gasoline leak in the intake manifold, the oil droplets in the cylinder body, the heat will be in the engine room after evaporation, once the occurrence of electrical sparks, at any time can cause fire, the consequences are very serious. When the injector internal leakage, will cause the fuel atomization spray injector is not good, the engine does not run smoothly, the mixed gas incomplete combustion, the phenomenon of black smoke exhaust pipe, and will lead to a significant increase in the amount of vehicle fuel consumption. When the injector external leakage fault, will cause difficulties, start the engine idling flameout, the loss of power, fuel consumption increase, operation surge and accelerated harmful fault. In addition, when the injector is connected with the air inlet pipe of the sealing surface is damaged, will cause the intake system leakage, resulting in additional air into the combustion chamber of the engine, causing the mixture too thin, causing abnormal engine running. 9 removal method of 1  injection; little or no spraying oil (1)   fuel oil air system; out of high or low pressure air in an oil pipe (2) the injector by grinding or replacement of (3) fuel pump oil is not normal according to the fuel injection pump fault troubleshooting method to find out the reasons with (4) high-pressure oil pipe leakage, tighten the nut tubing cracks should be replaced (5) injector wear replacement or grinding 2 fuel injection pressure is low (1  ); the pressure regulating screw loosening according to the provisions to adjust to the specified pressure and, the fastening nut (2) the pressure adjusting spring deformation adjust or replace (3)   needle stuck; cleaning or polishing (4) the spring seat and the top rod wear   repair or replacement parts; 3 injection pressure is too high (1  ); the pressure adjusting spring High elastic according to the provisions to adjust to the specified pressure, and tighten the lock nut (2)   needle stick; cleaning or polishing (3)   plug nozzle; nozzle cleaning or replacement nozzle (4  injector nozzle); oil spill: (1) the pressure adjusting spring fracture   the replacement of the new spring (2); a needle valve seat surface is damaged, replace (3) needle kill clean grinding or replacement (4) variable tight cap line (5) the replacement of the injector body surface wear grinding or replacement of 5 atomization adverse (1): injection pressure low pressure adjustment to the specified (2) nozzle seat is damaged or burnt grinding or replacement (3  ); the injector with surface cleaned waste 6 fuel injection line: (1)   nozzle plug with a diameter of 0.2-0.3MM; Steel wire dredge hole (2) &nb
