The code that is required is located at position (X). Record code (X) before the electronic unit injector is installed.\u003cbr\u003eThe fuel injectors contain no serviceable parts apart from the O-ring seal and the combustion washer. The clamp and setscrew are serviced separately. The pressurized fuel from the fuel manifold is injected into the combustion chamber by the electronic unit injector. The desired injection timing, injection quantity and injection pattern are controlled by the ECM depending on engine operating conditions.\u003cbr\u003eThe injection process is controlled using a two-way valve. The supply of electrical current to the solenoid controls the two-way valve. When the two-way valveis not energized the out orifice is closed and there is no fuel leak. In this condition the pressure in the control chamber and the pressure at the nozzle needle are the same. In this condition the spring pressure on the command piston keeps the needle closed.\u003cbr\u003eWhen an injection of fuel is required, the electrical current from the ECM charges the solenoid, which in turn energizes the two-way valve and lifts the valve.\u003cbr\u003eWhen the valve lifts the valve uncovers the out orifice. The fuel starts to flow and reduces the pressure in the control chamber. When the pressure difference at the nozzle needle exceeds the combined pressure of the control chamber pressure and the spring pressure, the nozzle lifts to start the injection process. The fuel coming out of the nozzle is atomized and injected as a very fine spray.\u003cbr\u003eWhen the injection needs to be stopped the electrical current to the solenoid is cut off and the pressure difference in the control chamber starts increasing. The increased pressure difference stops the injection process when the combined pressure exceeds the nozzle pressure.\u003cbr\u003eThe electronic unit injectors can be instructed to inject fuel multiple times during the combustion process.\u003cbr\u003eA close pilot injection occurs before the main injection.\u003cbr\u003eThe close pilot injection helps to reduce NOx and noise. The main injection period helps to increase the torque of the engine. The after injection period helps to reduce the amount of smoke that is produced.\u003cbr\u003eHow to Use The Doosan DX140LC-3 and DX140LC-5 Excavator Guide Manual:\u003cbr\u003eThis manual provides information for servicing the DX140LC-3 and DX140LC-5 Doosan Excavator. All service procedures are broken down into detailed steps, listed in their recommended sequence. The manual uses both photographs and drawings to help locate and itemize components. The table of Contents on the preceding pages is your best tool for finding the service procedure you need. Be certain to observe all Safety information included in these pages.\u003cbr\u003eA schematic of each of the major engine systems is provided at the beginning of the section of the manual devoted to troubleshooting and repairing that particular system.\u003cbr\u003eBasic safety precautions are list in the Safety section of the Doosan DX140LC-3 and DX140LC-5 Excavator Service Manual. Additional safety precautions are list in the Safety section of the owner\/operation\/maintenance publication. Specific safety warnings for all these publications are provided in the description of operations where hazards exist. WARNING labels have also been put on the product to provide instructions and to identify specific hazards.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53593318359371,"sku":null,"price":60.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-34_1cf6eb58-bbb6-4593-9fae-97f5f87bb326.png?v=1760374721","url":"https:\/\/manualbull.com\/products\/doosan-dx140lc-3-and-dx140lc-5-excavator-service-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
