What are the classifications of oxygen sensors?

Here is an introduction to the classifications of oxygen sensors: 1. Conventional oxygen sensors: There are mainly two types of oxygen sensors used in automobiles - zirconia type and titania type. Both types of oxygen sensors can be further divided into heated and unheated versions, with heated versions being more commonly used in vehicles. 2. Air-fuel ratio sensor: The air-fuel ratio sensor can continuously detect the air-fuel ratio across the entire range from rich to lean mixtures. Compared to conventional oxygen sensors, this type of sensor enables feedback control of the air-fuel ratio throughout the entire operating range of the engine, achieving optimal fuel consumption, emissions, and performance in all operating regions. In the air-fuel ratio feedback control systems for lean-burn engines, lean-burn sensors are employed. These sensors can continuously measure the air-fuel ratio in extremely lean mixture conditions, enabling feedback control in lean-burn conditions. 3. Nitrogen oxide sensor: The nitrogen oxide sensor is used to identify and verify the proper functioning of the three-way catalytic converter.

I've previously researched that oxygen sensors are primarily categorized by location into two types: upstream and downstream. The upstream sensor is located at the front of the exhaust pipe, responsible for detecting the oxygen level in the exhaust gas and feeding it back to the ECU to adjust the air-fuel ratio, ensuring cleaner combustion in the engine. The downstream sensor, positioned after the catalytic converter, monitors whether the converter is efficiently filtering emissions. Further subdividing the types, there are narrowband sensors that measure the basic air-fuel ratio—cost-effective but less accurate—and wideband sensors, which are more modern, capable of precisely measuring lean or rich mixtures, making them ideal for newer vehicles to aid in fuel efficiency. If a sensor fails, the most common issues are carbon buildup or aging heating elements, leading to excessive emissions and affecting fuel consumption, necessitating regular cleaning or replacement. I personally tried switching to a wideband sensor in my car and noticed smoother power delivery, with maintenance being less complicated.

What engine does the Shuailing e have?

Shuailing e is equipped with the 4DA1 series engine. Engine: If the vehicle has not stalled or has not been started after water ingress, it is necessary to replace the engine oil and oil filter, air filter, and the sealing rings during the process of draining water from disassembled engine components. If stalling or a second start occurs, in addition to the aforementioned components that need replacement, the engine connecting rods may also need to be replaced based on the situation, requiring an engine overhaul. Transmission: Transmission fluid and transmission filter. Vehicle fluids: All vehicle fluids, including engine oil, coolant, power steering fluid, brake fluid, etc., should be completely replaced if the water immersion is severe. Bearing components: If the water level reaches the engine hood and the immersion time is relatively long, it is advisable to replace components with bearings to prevent future noise and damage due to rust, such as the generator, air conditioning compressor, and four-wheel vehicle bearings. Electrical circuits: Depending on the extent of water ingress, it may be necessary to replace burnt or damaged electrical components and wiring.

Are Motorcycles Subject to Mandatory Scrapping??

Motorcycles that have reached the scrapping age limit must be mandatorily scrapped. The scrapping period for standard three-wheeled motorcycles is 7-9 years, while light two-wheeled motorcycles, light three-wheeled motorcycles, two-wheeled motorcycles, and sidecar motorcycles have a scrapping period of 8-10 years. The difference between recommended scrapping and mandatory scrapping: Recommended scrapping suggests scrapping, but if the vehicle still meets the requirements for continued use, it does not have to be scrapped. Mandatory scrapping means the vehicle must, without exception, be scrapped. There are four criteria for mandatory scrapping: Having reached the stipulated service life; After repair and adjustment, still failing to meet the national standards for motor vehicle safety technical requirements for in-use vehicles; After repair and adjustment or the adoption of control technology, still failing to meet the national standards for in-use vehicles regarding atmospheric pollutant emissions or noise; Failing to obtain the motor vehicle inspection compliance mark for three consecutive inspection cycles after the expiration of the inspection validity period.

Where is the keyhole of Geely?

Geely's keyhole is located on the door handle of the driver's seat. Reminder for unclosed car doors, triggering conditions: When the other three doors except the driver's seat are not locked properly, the secondary lock on the driver's side cannot be locked properly. Each time the secondary lock is pressed, it will automatically bounce back immediately to remind the owner that there is still a door not locked properly. Emergency switch for the tailgate, opening method: There is an emergency switch on the tailgate of the Baojun 560, which is a square slot with a side length of 8mm. In an emergency, a wider key or other hard object can be inserted and twisted to open it, thus escaping. Emergency ignition/shutdown function, activation method: At this time, pressing the start button for 12 seconds can still perform an emergency ignition. In addition, if an emergency shutdown is needed, pressing the start button for 2 seconds or pressing it three times within 3 seconds can force the engine to shut down.
