Is the 15s4c engine sourced from a joint venture vehicle?
2 Answers
No, it is not from a joint venture vehicle. The 15s4c engine is produced by SAIC Motor and is primarily used in the MG 3 and MG 5 models under the SAIC Motor brand. Below are the relevant details: 1. Introduction: The 15s4c engine features a valve drive mechanism with a hydraulic support roller rocker arm structure. This innovative valve drive mechanism offers the advantage of relatively low frictional torque, thereby requiring less driving force. This effectively reduces engine power consumption and lowers fuel consumption. 2. Maintenance of the 15s4c engine: Clean the air filter regularly. The air filter is directly related to the engine's air intake during driving. If the vehicle is driven only in urban areas, the air filter may not get clogged. However, if the vehicle is driven on roads with more dust, the air filter may become clogged or accumulate excessive dust, leading to restricted engine air intake. Additionally, a large amount of dust entering the cylinders can accelerate carbon buildup, causing poor engine ignition, insufficient power, and naturally increased fuel consumption.
I'm in the auto parts business and deal with various engine models regularly. I'm very familiar with the 15S4C engine. It first appeared in SAIC-GM-Wuling's vehicle lineup, being used in models like the Baojun 730 and Wuling Hongguang S. Technologically speaking, it's indeed a product jointly developed by SAIC and GM, with main characteristics being simple structure, durability, and affordable maintenance. Some domestic car manufacturers have borrowed its design concepts, but the core patents remain with the joint venture partners. This engine is particularly popular in the low-end market, thanks to readily available parts and widespread service networks, making it especially user-friendly for car owners in third- and fourth-tier cities.
