These models represent Shengkunda's latest achievements in high-power output, durability, and emissions compliance, and have been widely applied in global heavy truck logistics and engineering transportation scenarios.

Comprehensive Review of the Inspection Activities: From Production Lines to Research Frontiers in Full Interaction

At the outset of the inspection, the American client team, personally accompanied by Mr. Luo, General Manager of Shengkunda, formally entered the modern production park located in Huaiyin District, Jinan. The facility spans over 50,000 square meters and is equipped with a full industrial chain production line from raw material processing to finished assembly. The team first visited the precision casting workshop for heavy truck engines, where German-imported automated casting equipment and advanced Japanese heat treatment furnaces are used to ensure uniformity and high-strength performance of key components such as cylinder blocks and crankshafts. The clients were impressed by the production line's digital management system, which integrates Internet of Things (IoT) technology for real-time monitoring and data traceability, significantly reducing production error rates to below 0.1%. One American procurement supervisor commented on-site: "Shengkunda's manufacturing processes embody Industry 4.0 standards, which will provide reliable power assurance for our North American logistics fleet."

In the casting workshop, Shengkunda specifically showcased the Truck 371 Engine Assembly. The client team handled sample parts firsthand, marveling at their surface finish and weight optimization, which demonstrate Shengkunda's expertise in lightweight design.

Subsequently, the inspection group proceeded to the assembly workshop, where they witnessed the dynamic assembly process of the Heavy-duty truck WP10 engine assembly. Company engineers provided a detailed demonstration of the integration and installation of the turbocharger and electronic control unit (ECU), utilizing high-precision laser welding technology to ensure stable operation under extreme temperatures (-40°C to 150°C). Team members also participated in an interactive session, experiencing the engine's performance under simulated heavy-load road conditions via a virtual reality (VR) simulator. Data indicated that Shengkunda products maintain a power attenuation rate of less than 3% over a 100,000-kilometer test cycle, far superior to industry averages.

During the assembly demonstration, the truck equipped with the WP10.380E32 diesel engine emerged as another highlight. This model features a 9.726L displacement with a 6-cylinder water-cooled 4-stroke configuration, rated power of 280 kW (380 HP) at 2200 rpm, and an efficient EGR (exhaust gas recirculation) system combined with DOC+SCR after-treatment devices, meeting Euro V emissions requirements. Its maximum torque is suitable for urban-suburban mixed logistics and heavy engineering vehicles, such as Shacman and Beiben trucks, with idle stability reaching 99.5%, significantly reducing maintenance costs. Engineers demonstrated the ECU's remote diagnostic function on the actual machine, and the clients noted that this technology could seamlessly integrate with their fleet management systems, improving operational efficiency by 15%.

On the second day, the technical exchange session focused on Shengkunda's R&D center. This center is equipped with a testing platform valued at 50 million yuan, including engine test benches and emissions analyzers. Experts systematically explained the fuel optimization strategies for the Truck with WP10.380E32 diesel engine: through multi-point injection systems and variable valve timing (VVT) technology, fuel efficiency is improved by over 15%, while complying with Euro VI and EPA Tier 4 emissions standards. These innovations stem from the company's joint laboratory project with Tsinghua University's Automotive Engineering Department and have resulted in multiple national patents. During the session, the American team shared challenges in long-haul freight, such as power loss in high-altitude hypoxic environments. Shengkunda engineers promptly proposed customized solutions—an in-cylinder direct injection system integrated with a high-altitude compensation module—expected to increase torque output by 10%. The two parties engaged in in-depth discussions on potential collaboration models, including joint development of hybrid power-compatible engines, ultimately reaching a preliminary framework agreement. The initial trial order will involve the supply of 5,000 sets of core components, scheduled for delivery in the first quarter of 2026. Throughout the discussions, the heavy truck WP10 engine assembly, WP10.380E32 diesel engine, and 371 horsepower engine assembly were frequently referenced as potential customization bases, with the clients expressing interest in bulk procurement

Additionally, the exchange session particularly introduced the 371 horsepower engine assembly (WD615.47 model), which is dedicated to the Sinotruk Howo series. It features a 9.726L displacement with a 6-cylinder inline water-cooled turbocharged design, rated power of 273 kW (371 HP) at 2200 rpm, and maximum torque of 1500 Nm at 1100-1600 rpm, complying with Euro II emissions standards. It is suitable for dump trucks and tractor-trailers. Its compression ratio of 17:1 and 4-stroke direct injection technology ensure exceptional low-speed torque output. Engineers emphasized its reliability in high-temperature environments in Africa and the Middle East, with cumulative exports exceeding 100,000 units.
