Automotive sensors are the input devices of a car's computer system. Below is a relevant introduction about automotive sensors: Classification: Air flow sensor, ABS sensor, throttle position sensor, crankshaft position sensor, oxygen sensor, and oil pressure sensor, etc. Function: They convert various operational conditions of the vehicle, such as speed, temperature of various mediums, and engine operating conditions, into electrical signals to be transmitted to the computer, ensuring the car operates in its optimal state. Lifespan: The lifespan of different sensors varies: combustible gas sensors last about 2-3 years, conventional electrochemical ones 2-3 years, and infrared principle ones 3-5 years. The specific lifespan depends on the actual working conditions.

As an average car owner, vehicle sensors are the detection tools inside the car, specifically designed to monitor various conditions to help drive more smoothly and safely. For example, the oxygen sensor in the exhaust pipe detects emissions and tells the engine how much fuel to burn for better fuel efficiency and environmental protection; the temperature sensor keeps an eye on the engine temperature to prevent overheating; and radar probes scan the distance to surrounding objects when reversing, emitting beeps to avoid hitting walls or other cars. All this data is transmitted to the vehicle's computer system, which automatically adjusts operations, making driving much easier. Common issues include sensors getting dirty or damaged, which can trigger warning lights or reduced performance, but regular maintenance and cleaning can prevent these problems. Modern cars are equipped with more and more of these devices, like tire pressure monitoring systems that remind you to inflate your tires—truly convenient and practical, reducing my driving stress and repair worries. Understanding this principle makes me feel more confident behind the wheel.

Where is the horn location of Lavida?

Lavida has two horns, one high-pitched and one low-pitched, located behind the left and right fog lights in the bumper respectively. Legal basis for car horns: When driving on the road, safety is paramount. As a signal source, car horns can not only alert other vehicles and pedestrians but are also legally justified. According to Article 47 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when overtaking, motor vehicles should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. Functions of car horns: To alert pedestrians to avoid sudden entry into the driving path, preventing safety accidents; To remind vehicles ahead and behind to maintain appropriate distance and adjust their driving routes; When turning on sharp curves, honking can alert oncoming vehicles to yield; Taxis, ride-hailing cars, or rural buses can use horns to signal passengers to prepare for boarding.

Where is the power outlet in the BMW X5 trunk?

The power outlet in the BMW X5 trunk is located inside the trunk. Introduction to the trunk power supply: The backup power supply is an automatically driven standby power source that effectively prevents the driving circuit from lacking normal voltage. It can extend the required voltage for the circuit to ensure normal operation. Introduction to the car trunk 12V battery: The car trunk 12V battery is a rechargeable battery that can continue to be used after discharge. Types include lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. The positive electrode of the car trunk 12V lead-acid battery is lead dioxide, and the negative electrode is lead. During normal discharge of the car trunk 12V battery, the positive and negative electrodes react with sulfuric acid to form lead sulfate. When the concentration of the battery's sulfuric acid solution drops to a certain level, the battery must be recharged.

Why is there a rectangular cut made with a knife on the inner lining of the Lavida's trunk?

The rectangular cut made with a knife on the inner lining of the Lavida's trunk is necessary during assembly to allow the installation of the trunk support rods. A car trunk is not a safe: Do not store valuables casually. Remember not to leave cash, valuable digital products, premium liquor, cigarettes, or other valuables in the trunk. Prohibited items in the trunk: Storing lighters, gas cylinders, or adhesive items in the car trunk can easily lead to spontaneous combustion or explosions. For your own safety, never store these hazardous items in the trunk. Avoid long-term storage of food items in the trunk: Due to high temperatures inside the car, food can spoil quickly and produce unpleasant odors. Excessively heavy items: Long-term storage of heavy items can overload the trunk, affecting the suspension and increasing vehicle load and fuel consumption. Make rational use of the spacious trunk: Develop a habit of organizing items systematically.

How to Clean the Three-Way Catalytic Converter?

Three-way catalytic converter cleaning method: 1. Start the engine and turn it off after the water temperature normalizes; 2. Pour the cleaning agent into a dedicated device and connect the device's output connector to the vacuum tube; 3. Start the engine, maintain the speed at around 2000 RPM, open the flow control valve, and slowly drip the cleaning agent into the intake tract for 30 minutes; 4. After cleaning, keep the engine running for 35 minutes to expel residual liquid. Below is the mechanism of cleaning the three-way catalytic converter: The three-way cleaning agent enters the combustion chamber through the intake vacuum tube and burns, creating a high-temperature oxidizing environment around the three-way purifier. Through redox reactions, it converts sulfur and phosphorus chemical complexes adhering to the surface of the three-way catalyst, as well as incomplete combustion products of gasoline, into sulfur dioxide and carbon dioxide gases, which are then expelled. This achieves the purpose of cleaning the three-way catalytic converter and restoring the activity of the three-way catalyst.
