1, the concept of
refers to a high pressure common rail technology is a closed loop system by the fuel supply means in a high-pressure pump, pressure sensor and the ECU consisting of the injection process and the injection pressure is generated entirely separated from each other , by the high pressure pump to delivery high-pressure fuel to a common supply pipe, to achieve precise control of the oil pressure within the common rail, the high-pressure rail pressure irrespective of the size of the engine speed, oil pressure can be greatly reduced with the diesel engine speed It changes and, therefore, reduce the shortcomings of the traditional diesel engine. ECU controls the amount of fuel injection injector, the fuel injection amount depends on the fuel rail (common rail) pressure and length of time the solenoid valve is open.
2, action
High pressure sealing agent into the polyurethane structure concrete cracks and extends until all gaps (including imperceptible to the naked eye) filled, after water (water) accompanying the crosslinking reaction, the release of large amounts of carbon dioxide gas to produce osmotic pressure, high pressure and the secondary thrust osmotic pressed in and the elastomer fills all the gaps, to stanch purpose.
High Pressure filling plugging than conventional prior art, both a qualitative leap in terms of the principles of construction, or the construction speed. High pressure grouting technology is bound to its fast speed of construction, the construction principle of science, the higher the success rate of traditional construction methods section instead.
