The Functions of the Front Oxygen Sensor and Rear Oxygen Sensor

The functions of the front oxygen sensor and rear oxygen sensor are as follows: 1. The front oxygen sensor detects the oxygen concentration in the engine exhaust and provides this information to the ECU in the form of an electrical signal. The ECU then uses the oxygen concentration data to perform closed-loop control of the fuel injection volume. If the detected oxygen concentration in the exhaust is too high, it indicates that the engine's air-fuel mixture is too lean; conversely, if the oxygen concentration is low, it means the mixture is too rich. The ECU adjusts the fuel injection accordingly to achieve the optimal air-fuel ratio. 2. The rear oxygen sensor primarily measures the oxygen concentration in the exhaust after it has been treated by the three-way catalytic converter. If the data detected by the front and rear oxygen sensors are identical, it indicates that the three-way catalytic converter has failed.

How to Read a Car Speedometer?

For manual transmissions only, shifting around 2500 rpm is more appropriate. If rapid acceleration is needed, shifting above 3000 rpm can be chosen. Generally, the turbocharger operates optimally around 1800 rpm, where the engine power begins to increase significantly, and it hardly functions at low rpm.

What Causes the Squeaking Sound When New Car Wipers Scrape the Windshield?

New car wipers squeaking when scraping the windshield is caused by foreign objects between the wiper blades and the windshield, which create sharp noises due to friction. In this case, you can check and clean any debris on the wiper blades or underneath them to ensure the wiper area is clean. Wiper maintenance tips: 1. Avoid prolonged contact with the windshield: After parking, lift the wipers to prevent them from sticking to the glass for extended periods. Especially in scorching summer temperatures, the rubber blades pressed against the glass can easily deform or lose elasticity due to heat. 2. Repair windshield damage immediately: Road debris like gravel can easily chip the windshield, but minor dents are often overlooked. These not only damage the wipers but may also lead to full windshield cracking. It's best to have a professional auto detailing shop inspect or repair such damage. 3. Use rubber protectant: Rubber protectants available in the market resemble marker pens and are often included as freebies with cleaning products. Applying them to wipers enhances lubrication and extends the elasticity of the blades.

How to Turn Off the Cruise Control in the Mazda6 Atenza?

The Mazda6 Atenza's cruise control can be turned off by pressing the brake or clutch pedal, switching the control to the OFF position, or turning off the ignition when the car is stationary. More details about the Mazda6 Atenza's cruise control are as follows: 1. The cruise control system, also known as speed control or auto-drive system, maintains the vehicle's speed at the driver's set speed without the need to press the accelerator pedal, allowing the car to travel at a constant speed. Using cruise control on highways reduces driver fatigue by eliminating the need to control the accelerator pedal for long periods and helps maintain a steady speed, which can save fuel. 2. The cruise control can also be turned off by pulling the handbrake or shifting gears: Pulling the handbrake will reduce the vehicle's speed, thereby deactivating the cruise control, but it should be done slowly to avoid losing control of the vehicle. When the cruise control is active and the gear is in D, shifting to N will also turn off the cruise control.

Does BMW i mean imported?

BMW i does not mean imported. BMW's 3, 5, and 7 series are divided into two versions: standard wheelbase and extended wheelbase. The standard version is labeled with 'i', while the extended version is labeled with 'Li'. The imported 7 series models are all extended wheelbase versions, hence the 'Li' suffix. Methods to distinguish between imported and domestically produced cars: For the same model, check the rear of the car. If there are Chinese characters, it is domestically produced; if it is in English, it is imported. Alternatively, check the Vehicle Identification Number (VIN), a 17-digit code. If the first letter is not 'L', it is an imported car. Differences between domestically produced and imported cars: Some car models from certain brands are not available as domestically produced. Domestically produced cars refer to vehicles designed and manufactured by Chinese people, with independent intellectual property rights and Chinese brands. Imported cars refer to vehicles entirely manufactured abroad and then shipped to China for sale, with no Chinese involvement in the entire process, whether in terms of technology or materials.
