Bosch has been leading the way in promoting emission upgrades and creating a diesel common rail system that is more in line with the Chinese market. With the gradual improvement of the state's control of tail gas emissions, the improvement of tail gas emission standards has become a general trend. Bosch is playing an increasingly important role in the Chinese diesel engine market.

Recently, Weichai has announced that it plans to launch its "Euro 6" product in phases in 2016. As the main partner of Weichai's common rail system, Bosch will also become the main force for the listing of the "Euro 6" products of the Chairui Power Co., Ltd. As a supporter of major components for emission upgrades, Bosch will adopt what attitude it will use to protect the “Euro 6” products in the face of higher standards of emission policies.

Bosch CRS1-16 Provides Fourth and Fifth Emission Standard Solutions

Through communication with the Bosch Technical Center, China Trucking knows that Bosch is fully equipped with common rail system technology to meet higher emission standards. Weichai's five products will match Bosch CRS1-16+Denox6-5 or CRS1-18+ DPF, while Europe 6 products will use CRS1-18+Denox6-5+DPF, higher levels of common rail system will enable greater fuel efficiency, power will be greatly improved.

The CRS1-16 common rail system of Bosch is now widely used in China's National 4th Light Engine. It is a small, lightweight system designed specifically for the needs of the Chinese market. The high-pressure pump and injector used in the system have all been domestically produced. Chemicals, quality and price are all very competitive. It consists of four major components, common rail fuel injectors, high pressure rails, high pressure pumps and electronic control units. The working principle is that the high pressure pump provides the high pressure rail with pressure independently of the engine speed and fuel injection. The fuel is directly injected into the combustion chamber under the maximum injection pressure of 1600 bar. The whole process is monitored through the electronic control unit and completes one Work cycle.

Bosch's national five-emissions standard solution is based on the design of the National IV emission system, optimizing the CRS1-16 common-rail system, and combining Bosch's efficient SCR urea injection system, Denoxtronic 6-5, to pass urea through pyrolysis. In the SCR catalytic converter, the nitrogen oxides, which are the main pollutants in the exhaust gas, are reduced to harmless water and ammonia in the SCR catalytic converter. This method can not only greatly reduce the nitrogen oxides in the exhaust gas. It can effectively save about 5% of fuel, and the problem faced by this method is that the light diesel vehicles of the State Five will also need to use vehicle urea like the medium and heavy diesel vehicles of the National IV.

Another Five-Emission Standard for Bosch CRS1-18 and the "Euro 6" Emission Standard Solution

If the Bosch CRS1-16 common rail system is defined as the light engine common rail system best suited to the country's four emissions, then the Bosch CRS1-18 must be the most common rail system in line with the national five standard because it solves the CRS1-16 common rail. The system needs to consume vehicle urea to meet the emission standards. In design, the CRS1-18 uses a new, economical ball valve structure injector with a maximum injection pressure of up to 1800 bar. By combining it with an electronic control unit, five injections per injection stroke can be achieved. Reduced noise and fuel consumption, and then through the DPF filter, easily meet the country's five emission requirements.

There have been exaggerated assessments of the "Euro 6" emission standards, saying that the human body that meets the "Euro 6" emissions can directly breathe to describe the strict "Euro 6" emissions. In response to such stringent emission standards, Bosch is well-prepared to be a global leader in components and giants, common rail systems and aftertreatment systems, through the more efficient Bosch CRS1-18 common rail system combined with SCR urea injection. System, and then the last line of defense by the DPF, the cooperation of the three will be the perfect solution to this problem. There is reason to believe that a light engine that meets Euro 6 emission standards will not only provide good protection to the environment, but also provide the driver with a better driving experience—quietness, comfort, low fuel consumption, and good power. Of course, the price will also be the biggest challenge.

The Department of Science and Technology Standards Division of the Ministry of Environmental Protection, Xiao-Fei Fei, recently said publicly: “At present, China is developing a six-phase standard that is expected to be completed by the end of 2016.” Then, “State VI” is sure to come not far, and Bosch is ready .
