Oil is controlled by electromagnetic valve to avoid in the high pressure oil bubble and residual pressure

Oil is controlled by electromagnetic valve to avoid bubbles in high pressure oil and residual pressure solenoid valve used in diesel engine jiaodong online XiaoDeng times ssangyong in close cooperation with mercedes-benz nearly years hone to ascend out of the world's leading technology of diesel engine. Diesel engine itself represents the internal combustion engine field of high technology content, the same rate of output, and emissions of diesel engine generally are lower than those of gasoline engine oil consumption, and ssangyong eXDi used by direct injection with high pressure common rail diesel engine electronic control technology, especially with strong torque at low speed torque output, within the scope of a gasoline engine is bigger, ssangyong is equipped with a new type of diesel engine by using lower emissions, of CDPF technology to achieve the CDPF is short for catalytic diesel particulate filter, it is because of CDPF application of this technology, the new international models up to the euro 5 emissions standard, using the ssangyong that diesel engines, in order to. T he more diesel engine oil consumption, for example, km combined only litres of fuel. Diesel suvs on the market at present in China is not many, but not too less, mostly concentrated in low-end SUV, outdated technology, no will even adopted common rail technology, acme play out of the common rail technology, power has been hovering in kW. Basic wrong in China's domestic market and high-end SUV diesel version, because the high-end technology and equipment are unable to adapt to China's domestic bad quality of diesel. But as the world's largest automaker's sales pace is accelerated, the focus of the transfer to China with advanced technology of diesel engine in high-grade diesel SUV will quickly into China. And in this, by contrast, ssangyong diesel engines in terms of technology and adaptability have reached a good balance, is the leader of the domestic diesel SUV models. At the same time, I believe that with the rapid development of technology and the continuous improvement of energy saving, environmental protection consciousness, more and more diesel SUV will enter our daily life. Due to the high pressure oil pump adopt independent, ssangyong XDI diesel engine can provide high injection pressure, maximum of MPa, even short connecting the injector of high-pressure tubing also won't appear abnormal injection situation of uncontrolled system USES is the time pressure measurement principle of ECU according to the working condition, the oil temperature, air temperature, such as signal by oil pressure sensors to measure pressure value and transmission to the ECU, and make the measured pressure is given to the operation condition of the engine oil pressure pulse spectra comparison, again by ECU given signal control electromagnetic diesel pump control valve ( PCV) The opening and closing, to adjust the high pressure oil pump oil, to change the oil pressure in common rail oil canal, the oil pressure as the best value. Because of this, XDI engine oil pressure has nothing to do with the engine speed and load. Compared with the traditional injection system, electronic control common rail diesel fuel injection system of main characteristics. Flexible injection pressure is adjustable. For different working conditions using the optimal injection pressure, so as to optimize the comprehensive performance of diesel engine, due to the injection pressure does not change with speed, completely solve the traditional injection system because of the low injection pressure drop due to the low speed torque and the problem of low smoke. 。 High injection pressure. High injection pressure nitrogen oxides and particulate emissions can be controlled within a certain range. 。 The flexible control of fuel injection law. Such as pre injection, injection, 'boot' injection, etc. , as well as the use of the exhaust stroke exhaust aftertreatment injection, so as to ensure the excellent performance and fuel economy. 。 High control precision. Injection is controlled by electromagnetic valve, thus avoiding the bubbles in the high pressure oil and residual pressure is zero, so within the scope of the diesel engine operation, fuel injection quantity changes little, uneven pressure of each cylinder can be improved, and to reduce the vibration of the diesel engine and harmful emissions, and improve the driving performance. With electronically controlled common rail injection system, coupled with knowing the use in the turbocharger, driving ssangyong diesel and diesel cars without ever feeling, on the contrary power enough, little vibration, and the fuel consumption at a very low level, also let everybody enjoy off-road fun at the same time, also won't because of high fuel consumption and swept off-road.
