The maximum pressure diesel common rail system 250MPa

The world's top auto parts maker Denso (DENSO) recently announced that it has successfully developed simultaneously electrically controlled high pressure common rail system energy efficiency and exhaust gas purification .seat leon cupra turbocharger The system of 200MPa compared with the conventional common rail system , through the improvement of the structure of members , increasing the fuel injection pressure , to achieve the world's highest injection pressure of 250MPa , and a maximum of 3% fuel savings . Meanwhile , the system can also be harmful exhaust substances PM ( particulate matter ) produce the greatest reduction in the rate of 50%, NOx ( nitrogen oxides ) of the maximum production rate decreased by 8 % to achieve a truly effective exhaust gas purification .( turbo chra cartridge)

Diesel Common Rail System Features

Conventional diesel injection system and fuel injection quantity generated pressure contact with the cam and plunger together with increasing injection pressure and injection quantity of the engine speed increases . This diesel system has been unable to meet increasingly stringent emissions regulations and reduce fuel consumption desires.( camber plate)

Common-rail system (Common Rail Systems, referred CRS) will be stored at high pressure in the fuel pressure accumulator ( high-pressure fuel rail ) , and overcomes the shortcomings of traditional diesel injection system, essentially ,Leon cupra 1.8 turbocharger the characteristics are:

1, the injection pressure is generated does not depend on the engine speed and the amount of fuel injection systems , according to the different engine operating conditions and fuel flexible control of injection pressure to achieve low- speed and high injection pressure , reaching a low speed high torque , low emissions and optimization fuel economy purposes.( camber plates)

2 , the electronic control unit calculates the desired fuel injection quantity and injection timing , injection and then precisely by the injectors, and even multiple injection .

3 , a higher system pressure , the discharge capacity and better ,http://www.maxspeedingrods.co.uk/k04-022-turbo-turbocharger-for-audi-s3-tt-quattro-seat-leon-cupra-r-1-8-l.html lower fuel consumption.

Diesel common rail system components

Common-rail diesel injection system consists of the hydraulic system and the electronic control system. Which the hydraulic system and hydraulic system of low pressure and high pressure hydraulic systems.( turbo cartridge)

Low pressure hydraulic system components have included tank ,audi tt 1.8 turbocharger fuel pump , fuel filter and low pressure tubing. High-pressure hydraulic system includes fuel pump, high-pressure fuel rail , injectors and high pressure tubing . The electronic control system from sensors , electronic control unit , the actuator ( including the fuel injector with a solenoid valve , the pressure control valve , the glow plug control unit , the boost pressure regulator, the exhaust gas recirculation regulator, throttle, etc. ) and harness components.( turbocharger cartridge)

Among them, the injectors, fuel pump, high-pressure fuel rail , the electronic control unit for the four core components of diesel common rail systems.( turbo chra)

Denso improvement

Denso newly developed common rail system, through the injectors,seat leon turbocharger fuel pump and common rail structure improvements, can return 90% reduction in the amount of fuel in the tank , thereby significantly reducing the burden on the fuel pump. In addition, after the adjustment member is configured and the improvement of the material to achieve the pressurization, thereby further improving the degree of atomization of injected fuel , the combustion state of the combustible and thereby to reduce fuel consumption and exhaust gas purification effect. By reducing the burden of the fuel pump, both to achieve increased injection pressure, fuel pump and can keep the original size.

Environmentally friendly diesel common rail is largely determined by the combustion process, the fuel injection system and is one of the most important technologies. Currently, many countries are enhanced emissions normalized, and how to accurately control the fuel injection quantity, injection timing, injection pressure is a critical factor.

Denso in 1995 after the successful implementation of the common rail system commercialization, 2002 to achieve a 180Mpa (at that time the world's highest) injection pressure, 2008 to achieve a common rail system products of 200MPa. 2012, once again leading the world, developed the i-ART (intelligent-Accuracy Refinement Technology, the system built- in real-time monitoring of fuel injector pressure sensor, which is implemented by the injector injection quantity control , injection period ) , and to achieve a product of .

The development of 250MPa common rail system, applications worldwide passenger cars, commercial vehicles and agricultural construction machines. Meanwhile, Denso also is promoting the development of 300MPa common rail system .
