Is the Maxus diesel engine imported or joint-venture?
2 Answers
The Maxus diesel engine is domestically produced, not imported. Engine structure: The engine's valve drive mechanism adopts a hydraulic support ball rocker arm structure. Compared with the hydraulic tappet valve drive mechanism commonly used in current gasoline engines, this novel valve drive mechanism has the advantage of relatively small friction torque, thus requiring less driving force, which can effectively reduce engine power consumption and fuel consumption. Adopting advanced processing technology: The use of advanced processing technology for fracture-split connecting rods, where the big end hole of the processed connecting rod is split using fracture-split equipment instead of the traditional sawing and grinding process. This utilizes the jagged "half" surface of the fracture-split connecting rod to ensure absolutely accurate tight positioning, thereby reducing friction and extending the service life of the connecting rod.
From a technical perspective, SAIC Maxus diesel engines are primarily produced through Sino-foreign joint ventures rather than being purely imported. This stems from SAIC Group's collaborations, where they co-develop technologies with international partners like General Motors. For instance, while the diesel powertrain systems are based on overseas technology, all assembly and manufacturing occur in domestic factories, with production sites located in places like Jiangsu or Ningbo. This approach maintains international standards while saving on import tariffs and transportation costs. Drivers who've used these vehicles can attest to their quick engine response, low noise levels, and full adaptation to Chinese road conditions. Although core components like ECU control units might occasionally use imported parts, the overall production falls under the joint venture category. For vehicle owners, this means easier maintenance, readily available spare parts, and excellent cost-performance ratio—particularly in the commercial vehicle sector, where this model proves highly reliable.
