What engine does SAIC Maxus use?
1 Answers
SAIC Maxus engines are branded under SAIC Maxus itself. Here are some introductions to other aspects: 1. The engine valve drive mechanism adopts a hydraulic support roller 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. 2. To effectively reduce the overall vehicle weight, the 1.4-liter gasoline engine uses an aluminum alloy cylinder block, achieving a very significant lightweight effect. 3. Special materials and specially processed plastic intake manifolds are used to replace traditional metal intake manifolds, not only achieving a lightweight effect but also effectively reducing intake manifold wall resistance, improving intake efficiency, and increasing engine power. 4. Advanced processing technology is used for the fracture-split connecting rod. Special fracture-split equipment is used to split the large end hole of the processed connecting rod, instead of the traditional sawing and grinding process. This allows the use of the jagged "halves" 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. 5. A hot-sleeve camshaft is used. Compared with the original camshaft, it not only reduces the weight of the camshaft but also achieves higher cam profile accuracy and more precise valve timing.
