What Happens If You Don't Replace Spark Plugs?

If spark plugs are not replaced for a long time, it can lead to various issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power output, and most importantly, difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug—such as blistering at the top, damage, or melted electrodes—indicates that the spark plug is damaged and should be replaced. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance. The condition of the spark plug can be judged based on its color. A normal spark plug has an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged—showing signs of blistering, black streaks, cracks, or melted electrodes—the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, or there is oil leakage.

How to Deal with Water Vapor Inside the Car?

During winter driving, car windows are prone to forming water vapor, which can obstruct the view of the road ahead. Here are methods to eliminate water vapor inside the car: 1. Air Conditioning Defogging: Turn on the air conditioning and adjust the temperature inside the car to reduce the temperature difference between the inside and outside, thereby eliminating water vapor. 2. Defogging Spray: Use a professional defogging spray to remove water vapor from the car windows. Typically, one application remains effective for about half a month. 3. Wiping the Windows: Before driving, use a soft cloth to wipe the inside of the windows to prevent water vapor from forming while driving. 4. Opening the Windows: Open the car windows to allow air circulation between the inside and outside of the car, which can prevent water vapor from forming on the windows. 5. Dishwashing Liquid: Mix dishwashing liquid with water, soak a soft cloth in the solution, and wipe the inside of the windows to remove water vapor.

What are the common engine sensors?

There are 6 common engine sensors. Here are the detailed introductions: 1. Crankshaft Position Sensor: The crankshaft position sensor is used to detect engine speed and provide crankshaft rotation angle. It is installed near the flywheel. 2. Coolant Temperature Sensor: Used to detect the temperature of the cooling system to ensure the engine operates at an appropriate temperature. It is installed on the engine water passage. 3. Intake Air Temperature Sensor: Used to detect the temperature of air entering the engine, mainly to adjust fuel injection volume. When the external temperature is too low, it increases fuel injection; when too high, it reduces fuel injection. It is installed on the intake bellows. 4. Intake Pressure Sensor: Used to determine the fuel injection pulse width and ignition advance angle of the engine. It is generally installed on the intake manifold. 5. Camshaft Position Sensor: Also known as the phase sensor, it is installed near the camshaft. 6. Oxygen Sensor: To control vehicle emissions, the ECU monitors the concentration of exhaust gases to adjust fuel injection, bringing the actual air-fuel ratio closer to the theoretical air-fuel ratio. The oxygen sensor serves this function and is usually installed on the exhaust manifold.

What are the sidewall markings on Pirelli tires?

Pirelli's run-flat tires are marked with R-F or EUFORI. This means that if you see R-F or EUFORI markings on the sidewall of a tire, it indicates that the tire is a Pirelli run-flat. Here is some related information: EUFORI: EUFORI is a unique MIRS tire produced by Pirelli, representing Pirelli's innovative run-flat technology. Each brand has different markings for run-flat tires. Goodyear's run-flat tires are marked with ROF; Bridgestone's run-flat tires are marked with RFT; Dunlop's run-flat tires are marked with ROF or DSST; Dema brand run-flat tires are marked with SSR; Michelin's run-flat tires are marked with ZP. Additionally, some brands may have a five-pointed star on the sidewall to indicate run-flat tires. Important Notes: It is important to note that the primary purpose of run-flat tires is not to drive long distances after a puncture, but to maintain vehicle stability and prevent accidents. Therefore, even when using run-flat tires, it is essential to replace the tire as soon as possible after a puncture and avoid prolonged driving.
