Why is the engine warning light on in the Baojun 730?

[MacLucy]

Here are the reasons why the engine warning light is on in the Baojun 730: 1. Lack of regular maintenance: About 50% of engine failures are caused by poor maintenance. 2. Incomplete combustion: Poor engine combustion is the main reason for the engine warning light to illuminate. In automotive design, an oxygen sensor is installed to monitor the engine's combustion state, ensuring the engine operates efficiently and maintains a normal lifespan. If the combustion state is poor—such as high levels of hydrocarbons, carbon monoxide, or nitrogen oxides—it not only pollutes the environment but also leads to fuel waste and excessive engine wear. 3. Engine knocking: The engine is equipped with a dedicated knock sensor to monitor knocking. Engine knocking can indicate potential severe mechanical damage or significant power loss. Knocking is generally categorized as noticeable or unnoticeable. In unnoticeable cases, the engine control unit adjusts parameters to mitigate adverse effects. However, if the knocking exceeds the unit's adjustment range, the engine warning light will illuminate as an alert.
