What is the reason for the SVS light on the Shidai Yuling?

[DeTimothy]

The reasons for the SVS light on the Shidai Yuling are as follows: 1. Poor combustion state: To ensure the engine is in good working condition and has a normal working lifespan, an oxygen sensor is installed on the engine to monitor the combustion state. If the engine's combustion state is poor, it not only pollutes the environment but also leads to fuel waste and excessive engine wear. Poor fuel quality: The engine has specific requirements for fuel quality, especially as regulations increasingly demand higher performance from engines, which in turn raises the standards for fuel quality. In reality, some gas stations may not fully comply with these standards to provide fuel suitable for high-performance engines, leading to frequent occurrences of the engine warning light. Dirty engine cylinders or carbon buildup: After a certain period of use, the engine will inevitably accumulate carbon deposits, which are unstable and retain heat. This retained heat can cause uncontrolled ignition in the engine, leading to engine knocking. In such cases, the engine warning light will also illuminate.
