Five New Technical Points of Cummins Generator Set

Cummins generator set, as an emergency power generation equipment, after years of development, various technologies catch up with the international advanced level and can achieve self-sufficiency of Chinese people. The development of its technology specifically involves electromechanics, electromagnetics and mechanics.

1. Various mechanisms have been continuously improved and new technologies such as turbocharging and air intercooling have been adopted. Most diesel generator sets produced at home and abroad in the 1960s are four stroke water-cooled, and most diesel generator sets are naturally aspirated, while only a few are supercharged. They are characterized by large volume, small capacity and large fuel consumption. In order to reduce the size of the diesel generator set and increase the power, manufacturers of Cummins generators reduce the fuel consumption ratio. At the same time, in order to reduce production costs, turbocharging technology and air intercooling technology are widely used on diesel generator sets above 40kW. A few manufacturers also use multi valve technology to further strengthen the specific capacity of diesel generator sets. The materials of intake system, fuel supply mechanism, piston set, crankshaft and connecting rod components of diesel generator set have been continuously improved, and the production process has also been greatly improved.

2. In order to further improve the utilization rate of fuel, reduce the environmental pollution caused by the emissions and noise of the Mince generator set, and improve the power supply quality of the diesel generator set, electronic speed governing plate, electronic hydraulic speed governing plate and electronic injection technology are used. In addition, electronic injection technology, electronic speed governing technology or electronic hydraulic speed governing technology are added to the structural components of the fuel mechanism of the diesel generator set.

3. High pressure common rail fuel supply system is adopted. Precise electronic control fuel injection mechanism is used to automatically control the time, quantity and pressure of fuel injection, so as to reduce the noise of diesel generator set and effectively control the emission of harmful gases.

4. Single bearing composition and noise reduction technology are adopted. In order to reduce the volume of the AC synchronous generator and reduce the noise and vibration of the unit, diesel generator set manufacturers often adopt single bearing structure and noise reduction technology. In order to improve the overall performance of the AC synchronous generator, many manufacturers have changed from producing brush synchronous generator sets to producing more advanced brushless AC synchronous generator sets.

5. Micro processor and digital display technology are used in the power distribution and control system. Some diesel generator sets also have the function of remote control interface. In this way, the operation data of Cummins generator set, such as oil pressure, oil temperature, water temperature, speed, fuel oil and the voltage and frequency of Cummins generator set, can be monitored and automatically protected.

The above five points are the new technologies obtained by Cummins generator set industry in China through years of research and development, which make the comprehensive performance of diesel generator set more and more perfect and use more and more convenient, and bring certain advantages to people's lives. The future development direction is also clear, that is, energy conservation and emission reduction. Although such models have emerged in the market, the pursuit is endless. The diesel generator set industry still needs to continue the pace of research and development.
