What is the idle speed of the Changan CS55 engine?
2 Answers
Changan CS55's idle speed is normally between 600 and 850 rpm. Idle speed refers to the operation of the engine without load, only overcoming the frictional resistance of its internal components, without outputting power externally. The minimum speed required to maintain stable engine operation is called idle speed, which is one of the basic operating conditions of the engine. Idle condition refers to the state of the engine running without load. Introduction to Changan CS55: 1. Body dimensions: The body length is 4500mm, width is 1855mm, height is 1690mm, and the wheelbase is 2650mm. 2. Powertrain: Equipped with Changan H-series engine BlueCore 1.5T VVT DOHC all-aluminum engine, with a maximum power of 115kw and a maximum torque of 225nm.
I've been driving the Changan CS55 for two years, and the idle speed generally ranges between 700 to 800 RPM, depending on the engine temperature and environment. During a cold start, the RPM might rise to around 1000, but it stabilizes at slightly over 700 after a minute or two as the engine warms up. If the idle speed is too low, the engine may stall, while too high wastes fuel. So, it's good to keep an eye on the tachometer. If you notice unusual shaking or instability, it might be due to carbon buildup or a dirty throttle body needing cleaning. I recommend asking the mechanic to clean the intake system during each maintenance service to prevent idle issues, making the drive smoother and more fuel-efficient. After all, the engine in this Changan model is quite reliable, offering smooth daily commutes. Even with the AC on, the idle speed doesn’t noticeably rise, reflecting its smart overall design.
