K58-New Launched Engine
I believe that many people have learned about SDEC’s 12KTA58-G3 series engines, but they have only a limited understanding of the detailed data and parameters. Coincidentally, this article is related to the 12KTA58-G3 series. If you are interested, please watch it. After watching it, it will definitely bring you a lot of gains.
The new domestically developed high-end high-horsepower power station power was unveiled at the 21st China International Power Equipment and Generator Sets Exhibition in Nanjing. The power model is the 12VK series 12V170 electronically controlled high-voltage common rail power station engine; its model has been officially named 12KTA58 -G3 series, then let’s understand first:
SDEC 12KTA58-G3 series engine 12KTA58-G3 series engine details: SDEC 12KTA58-G3 series engine is a new high-end diesel engine independently developed by Shanghai New Power Automotive Technology Co., Ltd. (formerly SDEC Engine Co., Ltd.) in April 2022. The successful ignition of a diesel engine for a horsepower power station also marks the beginning of a new chapter for domestically produced high-end high-horsepower diesel engines. At the same time, SDEC K series engines have evolved from the in-line six-cylinder SC25K series to the development of multi-cylinder high-horsepower. SDEC 12KTA58-G3 Series engine final assembly 12KTA58-G3 engine is started in the test room and the test staff is debugging and testing the engine. SDEC 12KTA58-G3 series engine model meaning SDEC 12KTA58-G3 series engine model meaning, where 12 represents the engine gas quantity, which is a 12V type arrangement, K Represents the engine series code; TA represents pressurized water and air cooling, G represents power generation, and the number 3 represents the engine emission limit that complies with China’s Phase III emission standards for non-road mobile machinery diesel engine exhaust pollutants (non-road National III emissions).
SDEC 12KTA58-G3 series engine rear SDEC 12KTA58-G3 series engine body structure, fuel system, lubrication system intake and exhaust system arrangement The gear chamber structure, while the SDEC 6KTAA25-G3 series engine adopts the rear gear chamber structure, the cooling water spring adopts the gear drive mode, and the air chaos cover adopts the structure of one cylinder, one head and four valves, which is more convenient to use and maintain. It has more sufficient air intake, adopts an overall high-strength forged crankshaft, and tooth-shaped high-strength connecting rods with higher strength and good reliability.
The oil cooler is installed at the front and top of the engine. Six oil filters are installed on the left side of the oil cooler. The integrated oil filter seat has an oil tray underneath, which can not only effectively filter impurities in the oil and reduce engine failure. wear and tear.
At the same time, when disassembling and replacing the oil filter, the oil pan can collect the oil overflowing from the oil filter to reduce pollution. The oil cooler, oil filter assembly, supercharger, high-pressure common rail high-pressure oil pump, fuel fine filter, fuel filter, and intercooler fuel injection system are equipped with the CRS11.2 independently developed by the German Liebherr Group. The electronically controlled high-pressure common rail fuel injection system includes one LP11.2 high-pressure fuel pump, four common rail pipes, 12 L2 common rail injectors, two fine fuel filters and a coarse fuel filter.
Liebherr CRS11.2 electronically controlled high-pressure common rail system has up to 5 injection times, the system pressure is 2502200 bar (bar), and the maximum injection pressure can reach 2500 bar (bar); at the same time, 12KTA58-G3 series engines are equipped with SDEC The air intake system of the self-developed ECU electronic control unit adopts a four-turbocharger arrangement, and two turbochargers are installed on the left and right cylinders respectively, so that the air intake is more efficient and sufficient, the structure is more compact, and the appearance is beautiful. 12KTA58-G3 engine right side 12KTA58-G3 series engine technical parameters discharge SDEC 12KTA58-G3 series engine is 12V water-cooled, four-stroke, direct injection supercharged water-air cooling and four valves, using wet cylinder liner; the number of cylinders is 12 , the cylinder diameter is 170 mm, the piston stroke is 210 mm, the displacement is 57.2 liters, the normal power is 1986 kW, the standby power is 2185 kW, the rated speed is 1500 rpm; the noise is 102 decibels, and in terms of dimensions, SDEC 12KTA58- The G3 series engine is 2762m long, 1600m wide, 2195m high, and weighs 8100kg. Its emissions meet GB20891-2014 China’s third-stage emission standards for diesel engine exhaust pollutants for non-mobile road machinery.
In Terms of Power Common power: For variable load applications, no usage hour restrictions throughout the year. The average permissible power output for 24 hours of continuous operation shall not exceed 80% of the usual power rating.
Standby power: It is used when the power grid is out of power, or used under test conditions. The annual use time is no more than 200 hours. Continuous operation for 24 hours
The allowable output power shall not exceed 80% of the standby rated power.
12KTA58-G3 Engine Technical Parameters SDEC 12KTA58-G3 series engines are suitable for generator set power range and application. SDEC 12KTA58-G3 series engines are suitable for generator set power ranges from 1200 to 2000 kilowatts, and are widely used in large data centers, radio and television, hospitals, communications , petrochemical, oil field, aerospace thermal power, nuclear power, water supply mines and other emergency power supply purposes.
12KTA58-G3 cool set generator set 3D shows more conclusions SDEC12KTA58-G3 series engines were unveiled at the Nanjing Power Exhibition, marking the rise of high-end high-horsepower power station models of national independent brands. SDEC 12KTA58-G3 series engines will enter the market at the end of this year In the power station market, the K series will start to develop 16-cylinder and 20-cylinder V-type electronically controlled high-voltage common rail power in the next few years. It is also expected that SDEC12KTA58-G3 series power station models can enter the power station market as soon as possible.
