smog The bones are hard to be smashed, and the Chinese horse power is successfully ignited.
At the same time, in order to reduce pollution, there will be corresponding motor vehicle restrictions, but this is only a way to cure the symptoms. To really eradicate the winter smog "strickenness", one of the methods is to "install the purifier on the truck." ", that is, reduce the pollutant emissions in the car exhaust. However, reducing vehicle pollutant emissions is not a simple matter, especially for heavy-duty diesel vehicles. Of course, the bones are hard to be smashed. Looking at the upcoming six-emission standard for heavy-duty diesel vehicles, the major engine manufacturers are also happy. As for the Sixth Engine, there are already car companies that have come to the forefront. It is the Hanma Power of Hualing Xingma.
Hanma Power CM6D30 13-liter National Six diesel engine successfully ignited
As early as the end of 2016, Hanma Power's 12-liter National Sixth engine was successfully ignited. From 2017 to 2018, Hanma Power's 10-liter, 13-liter and 11-liter National Sixth emission standard engines were also successfully ignited. Moreover, the Valin heavy truck equipped with the Hanma Power Six engine is undergoing real vehicle testing in all parts of the country. I believe that in the near future we will be able to see the Hualing heavy truck country six models. So before you see the real car, Xiaobian will first take you to see what the magic of the Hanma Power Six Engine.
EGR exhaust gas circulation system
Mixed combustion reduces nitrogen oxides EGR exhaust gas cycle has a trick
At present, there are two main technical routes for mainstream engine manufacturers to develop the national six engine, namely EGR+DOC+DPF+SCR (referred to as EGR) and DOC+DPF+Hi-SCR (referred to as SCR) technical route. On April 13, 2018, the new generation CM6D30 13L engine with successful Hanma power ignition uses the EGR technology route, which uses 1800bar Bosch electronically controlled fuel injection + dual-channel EGR+D0C+DPF+SCR technology. The principle of action is that when the engine is running to generate exhaust gas, part of the engine exhaust gas enters the cylinder through the EGR valve to mix with the mixed gas.
EGR work start process
Since the inert gas of the mixed gas can delay the combustion process, that is, the burning speed will be slowed down, which causes the pressure forming process in the combustion chamber to slow down, which is also the main reason for the decrease of nitrogen oxides. Moreover, the exhaust gas can also reduce the oxygen concentration of the mixed gas after entering the mixed gas, so that the combustion temperature of the cylinder is lowered due to the decrease of the oxygen concentration during combustion, and NOx (nitrogen oxide) is generated under the condition of high temperature rich oxygen. Therefore, in general, the use of EGR technology can suppress the formation of NOx (nitrogen oxides).
Powerful and reliable 560 horsepower + B10 life of 1.6 million kilometers
Some people may be worried about reading this, will the performance of Hanma Power's 13-liter engine with EGR technology be affected? This is reassuring that the Hanma Power CM6D30 13L National Six diesel engine uses advanced turbocharger and High-voltage controlled injection and calibration technology delivers the most powerful power output with minimal fuel consumption. Its maximum power is 560 hp and the maximum torque is 2550 N.m. And the engine can reach a torque output of 1900N.m at 800rpm, meeting the power demand of the vehicle at low speed.
Hanma Power Engine
Performance is there, then what about reliability and security? On this point, Hanma Power actually thinks about it. The CM6D30 13-liter National Sixth diesel engine has optimized the process structure and structural structure at the beginning of the design, and has re-arranged the cooling and lubrication system. Together with the application of wear-resistant and high-temperature resistant materials, the reliability of the whole machine is greatly improved. Upgraded, the B10 has a lifespan of 1.6 million kilometers and is lighter in weight. In terms of safety, Hanma Power's 13-liter National Six diesel engine integrates the latest high-pressure HPD in-cylinder brake technology. The final result is that the engine's braking power is increased by more than 50% in the low- and medium-speed range, and driving safety is greatly improved. .
It can also be seen from the above introduction that as a pioneer of independent brand engine manufacturing enterprises, Hanma Power is always pursuing more efficient and environmentally friendly machine technology, because only in this way can it not be eliminated. This also confirms the statement of Liu Hanru, chairman of Hualing Xingma Automobile (Group) Co., Ltd. at the 2018 Business Conference: "If you want to develop in the heavy-duty truck market environment, Hualing must Master the core technology, especially for the heart of the truck - the engine."
