How to Adjust Car Mirrors for the Driving Test?

What are the reasons for the persistent illumination of the engine light on the Leoncino 500?

The reasons for the persistent illumination of the engine light on the Leoncino 500 include oxygen sensor failure and air flow sensor failure. Oxygen sensor failure: Generally, there are two oxygen sensors installed in a car, one before and one after the three-way catalytic converter. The front oxygen sensor is used to detect the air-fuel ratio of the engine under different working conditions, while the ECU adjusts the fuel injection amount and calculates the ignition timing based on this signal. The rear oxygen sensor primarily checks the working condition of the three-way catalytic converter. If the oxygen sensor is damaged or the sensor connector is damaged or loose, it can cause the mixture to be too lean or too rich, thereby triggering the fault light. It is necessary to visit a repair shop for troubleshooting or directly replace the sensor. Air flow sensor failure: The air flow meter converts the detected amount of inhaled air into an electrical signal and transmits it to the engine computer. Based on the optimal air-fuel ratio, the ECU indirectly determines the amount of fuel. If the air flow sensor or its circuit fails, the engine computer will not receive the correct intake air signal, making it unable to control the fuel amount properly. This can result in a mixture that is too lean or too rich, causing the engine to malfunction and sometimes accompanied by the illumination of the engine fault light. Replacing the air flow sensor with a new one will resolve the issue.

What are the requirements of China VI emission standards?

The China VI emission standards require a 50% reduction in carbon monoxide emissions for gasoline vehicles, a 50% decrease in the emission limits for total hydrocarbons and non-methane hydrocarbons, and a 42% stricter limit on nitrogen oxide emissions. The 'China VI' standard is an upgrade from the China V standard, imposing more stringent controls on pollutant emission limits. According to the plan, the 'China VI' standard will be implemented in two phases: 6A and 6B. The two phases are as follows: 1. Starting from July 1, 2020, vehicles that do not meet the 6A emission standard cannot be sold, registered, or licensed; 2. Starting from July 1, 2023, vehicles that do not meet the 6B emission standard cannot be sold, registered, or licensed.
