How is the durability of Changan engines?
3 Answers
Generally, it is guaranteed to last for 10 years, after which it becomes extremely difficult to find replacement parts. Below is relevant information: 1. Background: Changan Automobile's engines are self-developed by the brand. In the early stages, the H-series engines were primarily used. The H-series engines are inline 4-cylinder, 16-valve, all-aluminum engines, representing Changan's latest achievements in independent R&D by integrating international advanced technologies. They possess complete independent intellectual property rights and embody Changan's outstanding performance in energy efficiency, power, environmental protection, safety, and comfort, offering consumers a higher quality experience. 2. H-series engines: The H-series engines were planned to be installed in Changan's main self-branded sedan models, with production starting in 2010, designed to meet market competition from 2010 to 2025. This series of engines features prominent advantages such as 'high power, high torque, low emissions, and low fuel consumption.' The Jiangling brand engines produced by Jiangling Machinery Factory, a subsidiary of Changan Group, and the engines used in Changan minivans are imitations of Japanese models. Jiangling engines are as renowned as Dong'an engines, and they are likely among China's earliest manufacturers of small-displacement engines.
I've been driving a Changan CS75 for almost two years now, mainly for city commuting and weekend road trips. The engine has proven quite reliable with no major breakdowns. The Blue Whale series engine delivers smooth power output and strong acceleration, while maintaining relatively low fuel consumption at around 8 liters per 100 kilometers. However, I've noticed that for long-term durability, regular maintenance is essential - like changing the engine oil every 5,000 kilometers, preferably with full synthetic oil. Also, there's slightly more noise during cold starts in winter, but it disappears after the engine warms up. Overall, it's quite good among domestic vehicles. With careful driving, it can easily last 100,000 kilometers without major issues.
From a technical perspective, the durability design of Changan engines is quite pragmatic. They use materials like aluminum alloy cylinder blocks that reduce weight and improve heat dissipation, which benefits longevity. In my experience in the automotive industry, cases like the Blue Core 1.5T engine with over 130kW maximum power output demonstrate simple structures with fewer failure points, making them reliable for 5-10 years of use. However, it's important to avoid frequent overloading or prolonged high-RPM driving, as this accelerates wear. Compared to Japanese brands, some details like sealing gaskets may be slightly weaker, but replacement parts are affordable. Overall, with proper maintenance, they are a reliable choice.
