How to Check the Working Condition of a Used Car Engine?

[ErinLynn]

To inspect the working condition of a used car engine, first start the engine and carefully listen for any noises or irregularities. Then, take the car for a drive to feel whether the engine's power output is smooth and if the power response is quick. Finally, if possible, read the engine's fault codes to check for any issues. More details are as follows: 1. The definition of engine working condition refers to the operating state of the equipment under conditions directly related to its operation. The engine's operating state with the lowest fuel consumption rate is called the economic condition; the operating state when the load exceeds the rated value is called the overload condition. 2. Engine working condition, or the engine's operating state, is mainly characterized by the engine's output power and torque at different speeds. The engine can be divided into eight basic working conditions: starting, post-start, warm-up, idle, partial load, full load, transition, and dragging.
