The government's role in emission control has become a critical topic as China begins to align with international standards like Euro IV. Ni Hongjie, chairman of the China Internal Combustion Engine Industry Association, highlighted that heavy-duty diesel engines must meet these stricter emissions requirements. Two main technologies are available globally: Selective Catalytic Reduction (SCR), which involves post-processing to reduce nitrogen oxides, and Exhaust Gas Recirculation (EGR) combined with particulate traps, which reduces pollutants before combustion. While both have their pros and cons, SCR is considered more straightforward and easier to implement on existing Euro III models without strict oil quality demands.
However, implementing SCR requires nationwide infrastructure changes, such as ammonia injection at gas stations. This involves coordination across multiple sectors, not just petroleum companies. The National Development and Reform Commission plays a crucial role in ensuring a systematic approach to meet future emission standards, including comprehensive planning and regulation.
In contrast, countries like the U.S., Europe, and Japan focus on long-term compliance rather than just new vehicle standards. If vehicles fail to meet emission requirements after several years, manufacturers face hefty fines, pushing them to ensure durability throughout the vehicle’s lifespan. Dr. Zhan Rijing from the Southwest Research Institute emphasized the need for proper detection methods, enforcement, and incentives to support China’s transition to higher emission standards.
Yan Hui from Mann’s Commercial Vehicle Management pointed out that Chinese automakers should align with global standards to compete effectively. He stressed the importance of policy consistency and fairness, noting that the government must guide consumption while setting reasonable rules. With proper strategies, he believes China could surpass Western automakers within 10 to 15 years.
Gasoline engines still lag behind diesel engines in terms of technology and performance. Many domestic manufacturers lack the resources to develop advanced systems, relying instead on foreign partnerships or copying designs. However, companies like Chery and Geely show promise in independent development, drawing parallels to Hyundai’s rise in the U.S. market.
Talent migration is also playing a key role. Professionals returning from abroad are contributing to the growth of China’s automotive industry, especially in areas like engine control systems. Companies like Delphi and others are investing in local talent, helping bridge the technological gap. As more expertise flows into China, the country is gradually closing the distance with Western counterparts, and the day when it leads the global automotive industry may not be far off.
