Guided by the organic integration theory and combined with the changes in the purchase motivation of new energy vehicle consumers, the process of transformation from external motivation to internal motivation is deconstructed from policy guidance, marketing and cognitive formation, concept establishment and cognitive internalization. The analysis finds that the purchase motivation is dominated by external regulation, the main regulation process and motivation are to obtain policy subsidies. Secondly, the internalization and regulation of purchase motivation are blocked in the process from outside to inside, consumers’ cognition and acceptance of new energy vehicles are at a low level. Relevant suggestions are proposed based on the aspects involved in external regulation.

EU and some other developed countries will implement Carbon Border Adjustment Mechanism (CBAM) upon the commodities imported from the developing countries. In order to distinguish the impacts of CBAM on Chinese automotive industry and to design the countermeasures, this paper comprehensively analyzes the related rules of EU CBAM, current status of Chinese automobile exports to Europe, domestic carbon pricing policies and carbon accounting mechanisms. It is found that, although there is little impact on Chinese automotive industry in the short term. However, in the long run, CBAM will cover the life cycle carbon footprint of the products, this policy has shown that it is urgent for China to gear its carbon governance institutions to the international conventions. To meet the challenges imposed via CBAM, the automotive enterprises should improve carbon accounting, management capacity and green supply chain management as well as explore internal carbon pricing if the conditions permit. The government should guide and help the enterprises to adapt to the stricter carbon rules of the developed countries, as the significant part of the exporters service system.

Industrial reform and innovation make China's automobile industry face more difficulties and challenges, but also pregnant with greater opportunities. On the whole, China's automobile industry has achieved remarkable development achievements and has become the most important part of the global automobile industry, continues to lead the global automobile industry to electrification, intelligence, networking and service.

The Intelligent Vehicle Cyber-Physical System (IVCPS) can control the operation trajectory of vehicles based on road and vehicle information resources in real time, which has great potential in reducing vehicle energy consumption. However, the current studies on Cloud-Based Predictive Cruise Control (CPCC) architecture ignore the feasibility of architecture implementation and application, without verifing the rationality of the architecture. To establish the links among architecture, application and verification, promote multi-domain and multi-disciplinary collaborative design, joint simulation as well as system integration in IVCPS, this paper proposes the modeling method of IVCPS based on Model-Based Systems Engineering (MBSE). Firstly, the overall layered architecture of IVCPS is constructed and the elements of each layer of the architecture are clarified. Then Systems Modeling Language (SysML) is utilized as the modeling tool and the Requirement analysis-Functional analysis-Logical analysis-Parametric calibration (RFLP) modeling framework is constructed. Finally, a typical scenario of CPCC system within IVCPS is taken as an example. The RFLP framework is utilized to model and analyze the requirements, functions, logics and parametric calibration of the CPCC system. The modeling results prove that MBSE can realize the unified modeling of the requirement analysis, function decomposition, logical architecture design and system parameter calibration of the CPCC system, promote simulation verification of the theoretical architecture of the CPCC system and be able to test and analyze the effectiveness of the CPCC architecture in optimizing the running trajectory and reducing fuel consumption of intelligent connected vehicles. This study lays a foundation for improving the interactivity, reusability and compatibility of IVCPS system modeling.

In order to meet the goal of carbon neutrality, diversified development is required. In addition to adopting electrification and fuel cell technology, it is also necessary to develop zero-carbon or low-carbon fuel Internal Combustion Engine (ICE) to meet the needs of different application scenarios. Ammonia, as a zero-carbon fuel and hydrogen carrier, has received increasing attention in the era of carbon neutrality. Many research institutions and universities have carried out research on ammonia as a fuel for ICE in the past 20 years. This review analyzes the feasible methods of ammonia application in ICEs based on a brief summary of the combustion characteristics and combustion mechanisms of ammonia and mixed fuels with other fuels, proposes new characteristics of ammonia ICEs compared to fossil fuel ICE and the key technologies that need to be addressed in future applications. The existing research shows that using high active fuels to ignite ammonia fuel is a feasible technical solution for ICEs. For Spark Ignition Internal Combustion Engine (SI-ICE), gasoline, natural gas and hydrogen can be used for ignition. Compared with traditional gasoline engines, gaseous ammonia reduces the power performance of the SI-ICE without changing the engine structure, while increasing the emissions of NO_x and unburned NH₃. For Compression Ignition Internal Combustion Engines (CI-ICE), low auto-ignition temperature fuels such as diesel and Dimethyl Ether (DME) can be used for ignition. Compared with pure diesel or DME ICE, the power performance of ammonia ICE decreases and emissions are related to the fuel mixture ratio. Among all ignition fuels, hydrogen fuel has the greatest potential for improving combustion and is zero-carbon emissions. Therefore, ammonia-hydrogen fusion engines are very competitive zero-carbon power in the era of carbon neutrality. Finally, there are some problems that need to be solved for the future application of ammonia-hydrogen mixed fuel, including the development of dedicated ammonia injection systems, suitable post-treatment systems and on-board ammonia cracking systems.

At present, the main New Energy Vehicles (NEV) on the market are electric vehicles, the popularity of electric vehicles is inseparable from complete basic charging facilities. The construction of NEV charging facilities has problems such as narrow coverage, single profit model and long return period. Based on a comprehensive analysis of the charging facilities considered by domestic and foreign users when purchasing electric vehicles, the relationship between parking and charging, the management and service relationship of charging facilities and the application of Public Private Partnership (PPP) mode in the construction of NEV charging facilities, suggestions are proposed from policy orientation, enterprise operation autonomy and the construction of NEV service platforms.
