What are the classifications of oxygen sensors?

Oxygen sensors can be classified into: standard oxygen sensors, air-fuel ratio sensors, and nitrogen oxide sensors. The automotive oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system, playing a key role in controlling vehicle exhaust emissions, reducing environmental pollution, and improving the fuel combustion quality of the engine. Below is an introduction to these three types of oxygen sensors: 1. Standard Oxygen Sensor: Automotive oxygen sensors mainly include zirconia and titanium dioxide types. Both types can be further divided into heated and unheated versions, with most vehicles using the heated type. 2. Air-Fuel Ratio Sensor: The air-fuel ratio sensor can continuously measure the air-fuel ratio across the entire range from rich to lean mixtures. Compared to standard oxygen sensors, this type of sensor enables feedback control of the air-fuel ratio throughout the engine's operating range, achieving optimal fuel consumption, emissions, and performance in all conditions. 3. Nitrogen Oxide Sensor: The nitrogen oxide sensor is used to identify and check whether the function of the three-way catalytic converter is normal.

How to Replace the Air Conditioning Filter in Emgrand GL?

Replacing the air conditioning filter in the Geely Emgrand GL involves the following steps: 1. Open the glove box and release the clips on both sides by pulling them with your fingers. 2. Lift the glove box upwards to remove the clips. 3. After lowering the glove box, you will see a black cover plate; press the clips on both sides to remove the cover and expose the air conditioning filter. 4. Take out the old air conditioning filter and replace it with a new one. Below are the functions of the air conditioning filter in the Geely Emgrand GL: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, providing strong and long-lasting moisture adsorption.

Can I Ignore the Engine Malfunction Light?

It is temporarily acceptable to ignore the illuminated engine malfunction light. This commonly referred to yellow engine malfunction light is also known as the fuel injection system fault light. As long as there are no noticeable abnormalities in engine power or sound, you can continue driving. This is because the ECU (Engine Control Unit) has a fault substitution program. Engine malfunction signal: The engine malfunction signal is issued by the ECU, which controls all electronic components of the engine, including electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems such as intake, exhaust, fuel, ignition, and timing. If the engine malfunction light comes on, you must visit a nearby repair shop for inspection. Coolant temperature gauge: First, check the coolant temperature gauge and oil pressure warning light. If these indicators show no warnings, the vehicle can still be driven, but you must pay attention to controlling the speed and promptly drive to a repair station for inspection.

Does the 6th Year Vehicle Inspection Require a Physical Test?

The sixth-year vehicle inspection requires a physical test. Assuming the vehicle meets the exemption conditions and the driving license inspection period is 2014, then during the six years from 2014 to 2019, it can enjoy two exemptions from physical testing, only needing to apply for an annual inspection sticker every two years. By the 6th year (i.e., 2019), the vehicle is no longer within the exemption range and will require a physical test, along with applying for the annual inspection sticker. Below are the vehicle inspection cycle regulations: 1. Operational passenger vehicles must be inspected once a year within 5 years; after 5 years, every 6 months. 2. Trucks and large or medium-sized non-operational passenger vehicles must be inspected once a year within 10 years; after 10 years, every 6 months. 3. Small and mini non-operational passenger vehicles must be inspected once every 2 years within 6 years; after 6 years, once a year; after 15 years, every 6 months.

How Does an Oxygen Sensor Work?

The basic working principle of an oxygen sensor is: under certain conditions, it utilizes the oxygen concentration difference between the inside and outside of the zirconia element to generate a potential difference. The greater the concentration difference, the larger the potential difference. The oxygen content in the atmosphere is 21%, while the exhaust gas from rich mixture combustion contains virtually no oxygen. The exhaust gas produced by lean mixture combustion or misfires contains more oxygen, but still significantly less than the oxygen content in the atmosphere. Additional information about oxygen sensors is as follows: 1. Under high temperature and the catalysis of platinum, the oxygen attached to the oxygen sensor is completely consumed, thus creating a voltage difference. A rich mixture outputs a voltage close to 1V, while a lean mixture outputs a voltage close to 0V. 2. Based on the voltage signal from the oxygen sensor, the air-fuel ratio is controlled to adjust the fuel injection pulse width. Therefore, the oxygen sensor is a key sensor for electronic fuel metering control.

What is the reason for the cancellation of the small car lottery application result?

The reasons for the cancellation of the small car lottery application result include: errors in the application information, changes in circumstances, or the desire to reapply after withdrawing the application, which requires submitting a new application. Applicants can log into the system, enter the user center, click on the "Application Form" in the configuration indicator function area, and then click on "Reapply" on the application form page, following the system prompts step by step. Alternatively, they can bring their valid ID card and a copy to the nearest district office for external services. Validity period of the lottery: After winning the lottery, the validity period is 6 months. If the indicator is not used within the validity period, it will become invalid. In such cases, the applicant will not be able to participate in the lottery for two years and must wait until after this period to reapply. Definition of the lottery: The lottery is a regulatory policy introduced by the state to curb excessive growth in car numbers and environmental pollution. It is a form of purchase restriction policy, where only eligible citizens can participate in the lottery.
