Fuel economy is the real test. The most significant difference between the State III engine and the State II engine lies in the switch from a mechanical pump to an electronic fuel injection (EFI) system. This change allows for more precise matching of fuel supply with air intake, leading to more complete combustion and better energy efficiency. As a result, it achieves both fuel savings and lower emissions. This means that the advanced performance and integration of the EFI system play a crucial role in determining the overall effectiveness of the State III engine. For example, the Iveco Light Bus equipped with the Sofim III engine demonstrates this advantage. The engine is imported as a whole from Italy and uses the advanced German Bosch high-pressure common-rail system, which ensures excellent compatibility. As a result, its fuel consumption is about 10% lower than that of the Sofim II engines. Industry data shows that diesel vehicles are typically 20% more fuel-efficient than gasoline ones. Compared to some other diesel models, the Iveco III product is about 10% more efficient. In practical terms, this translates to nearly a 30% reduction in fuel costs. Reliability is the real key. Currently, there are three main technologies used to meet the National III emission standards in commercial vehicle engines: electronically controlled high-pressure common rail systems, electronically controlled single-pump systems, and electronically controlled EGR systems. Among these, the high-pressure common rail technology is widely regarded as one of the most mature and reliable solutions for diesel engines under National III standards. Many well-known commercial vehicle manufacturers have adopted this technology. Since it's a well-established European technology, domestic joint ventures with European partners have been using it for years. For instance, Nanjing Iveco introduced National III products to the Chinese market as early as 2004. After extensive road testing and user feedback, both oil adaptability and vehicle stability have gained strong market recognition. Additionally, its unique filtration self-detection alarm system helps prevent damage from substandard fuel. It is reported that since Beijing implemented the National III emission standards in 2005, sales of the Iveco Light Bus in the city have consistently increased by an average of 30% annually. Service is the final word. It is known that some commercial vehicle companies lack core technologies for National III engines and have to upgrade their engines on short notice to meet the standards. Lin Wei, Secretary-General of the China Light Vehicle United Analysis Association, mentioned that after full implementation of National III, after-sales service becomes a critical challenge. This includes whether spare parts are available, whether professional diagnostic equipment is in place, and whether maintenance staff are properly trained. “The National III engine uses EFI technology, which requires higher standards for both equipment and personnel. Many companies had very little time to prepare, making it difficult to ensure proper diagnostics and maintenance.” According to reports, after the launch of National III products in 2004, Nanjing Iveco began equipping its national service network with professional engine diagnostic computers. “Because the Iveco III products were launched early and had large inventory, our after-sales team has accumulated extensive experience, ensuring that customers receive timely and professional support,” said Shuai Guowang, Vice Minister of After-sales Service at Nanjing Iveco. Three Key Factors for Choosing Commercial Vehicles in the National III Era After a six-month grace period, China’s National III emission standards were fully implemented starting in July. People are now paying close attention to which manufacturers can deliver top-tier National III products. As everyone knows, the engine is the decisive factor in a vehicle’s emission level and performance. Therefore, economic efficiency, reliability, and after-sales service are the three most important reasons people choose National III commercial vehicles.
