On June 18, 2011, FAW Jiefang Company Wuxi Diesel Engine Factory held the “ National IV Product Promotion and Press Conference â€. Qian Hengrong said: “According to the most advanced diesel engine development process in the world, With the design concept, design method and design structure, and the development goal of designing the most competitive engine, the IV product launched by Xichai has achieved “four leadâ€.â€
According to Qian Hengrong, FAW Xichai State IV products have achieved “four leading†technology routes, proprietary technologies, cost-effectiveness, and platform series. Xicai IV series diesel engines have introduced products designed and developed for high performance and emission, high burst pressure and high heat load. Their self-developed low-emission combustion chambers have fully ensured efficient and clean combustion in cylinders. The intelligent motor-driven hot-end EGR system solves the technical problems of the hot-end EGR valve system in medium and heavy commercial diesel engines. The unique double water cylinder head design can fully meet the needs of 180-200bar burst pressure and high heat load. Independently developed engine braking technology achieves higher braking power. The use of full-floating plastic cylinder head cover technology achieves lower overall machine noise. The National IV product launched by Xichai has lower fuel consumption, higher reliability and safety on the basis of State III. Under the premise of ensuring that the overall performance, reliability, and durability are in the leading position in the industry, the Xichai IV engine ensures a competitive advantage in terms of cost performance. In particular, the design of the Xichai IV engine is based on the principle of “standardization, universalization, and serializationâ€, which strictly enforces the national mandatory standards, minimizes the use of special parts, and maintains the external dimensions and interface positions as much as possible. State III models are the same, making the xicai match versatility and inheritance.
