The strengths of Cummins high pressure common rail engine

    The article reads: 1. Admits the ancestors of the electronic control device, making the injection history control is very convenient, and more controllable parameters, is conducive to the entire process of diesel combustion optimization, electronic control of the piezoelectric implementation of the high switching valve frequency, to achieve The quick oil-breaking capability has very high control accuracy. There are no signs of bubbles and residual pressure in the high-pressure oil circuit. Therefore, in the diesel engine operation range, the change in the injection quantity per cycle is small and the oil supply to each cylinder is uneven. Improve. 2. Admitting high-pressure common rail method for oil supply, the pressure of the fuel injection system is small, the mutual influence between the injectors is small, the pressure size is independent of the engine speed, the injection pressure control accuracy is high, the injection quantity control is correct, and the pressure is high. Common rail

    1. Admitting the ancestor's electronic control device, making the injection history control very convenient, and more controllable parameters, is conducive to the full optimization of the diesel combustion process, electronic control of the piezoelectric implementation of high switching valve frequency, to achieve a quick break Oil control, the control accuracy is very high, there will be no signs of air bubbles and residual pressure in the high-pressure oil circuit, so in the diesel engine operation range, the change of fuel injection volume per cycle is small, and the uneven oil supply of each cylinder is improved.

    2. Admitting high-pressure common rail method for oil supply, the pressure of the fuel injection system is small, the mutual influence between the injectors is small, the pressure size is independent of the engine speed, the injection pressure control accuracy is high, the injection quantity control is correct, and the pressure is high. The fuel injection pressure in the common rail system is flexible, and the optimum injection pressure can be determined for differential operating conditions to optimize the comprehensiveness of the diesel fuel.

    3.Adoption of electronically controlled high pressure common rail technology comprehensively optimizes the injection discipline of the diesel engine (close to aspiration, easy to achieve pre-injection and multi-injection, can independently control the injection timing flexibly, with full high injection pressure, can be controlled The smaller values ​​of nitrogen oxides and particulates meet the requirements for satisfactory emissions, while at the same time ensuring excellent dynamics and properties.

    Low Pressure Screw Air Compreessor

    At present,some industries that need low pressure air compressor are using conventional air compressors plus pressure reducing valves in work, whose production process is a waste of resources. In this case, we have developed Hongwuhuan LF series low pressure screw air compressors to directly output the working pressure you need to reduce waste and save you money. Choose the right working pressure can save you more than 30% of electricity bill. We often use 3 bar air compressor or 5 bar air compressor to save energy.
