What brand is Torch spark plug?

Torch spark plug is a product of the Torch brand, a domestic brand under Zhuzhou Torch Spark Plug Co., Ltd. Where is the spark plug located: The spark plug is installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. Over the past decade, most car engines have been updated to connect the ignition coil directly to the spark plug. What are the effects of a faulty spark plug: If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug, such as scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plug is damaged and should be replaced. Steps to replace a spark plug: Open the hood and remove the engine's plastic cover. Disconnect the high-voltage ignition wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one, ensuring to check for and clean any external debris like leaves or dust. Insert the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and reattach the cover.

Why is there no traffic violation record found online three days after running a red light?

After running a red light, the notification message for illegal photo capture is usually received within 3 to 7 days, with the latest being around 13 days. However, some cities now offer "instant electronic police capture alerts," where you can receive an SMS notification within 5-10 minutes of being captured. But this notification does not equate to a traffic violation; it merely serves as a capture alert. The final determination of whether it constitutes a violation takes 3-7 days. If it is indeed a violation, you will receive another SMS notification. For violations captured by surveillance cameras, vehicle owners generally do not receive violation messages immediately. There is a delay, and the duration varies. After an electronic camera captures a violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center, where it is compiled and then verified by the relevant traffic police personnel. If confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via SMS. After receiving the violation SMS, the vehicle owner must go to the traffic police department where the violation occurred within one month before the annual vehicle inspection to address the violation. Generally, if a vehicle owner suspects a violation, they can use 15 days as a benchmark. If no violation SMS is received after 15 days, it is likely that no violation was recorded. Traffic violation query methods: Traffic violation queries refer to checking motor vehicle violations of traffic management through online platforms or query terminals. Methods include website queries, phone queries, SMS queries, and mobile app queries. Website query: You can search for "vehicle violation query" and input your vehicle information to check. Phone query: You can call local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be processed at the location where they occurred or at the vehicle's license plate issuance location. For on-the-spot violations, such as those caught directly by a traffic officer, they must be handled at the violation location. SMS query: Open your phone's SMS interface, enter "WZ" followed by your license plate number and color, and send it to 1062650001. Mobile app query: Open the "Traffic Management 12123" app, select "violation query," and address any unresolved violations.

Should You Use P Gear or N Gear for Warming Up the Car?

If the intended direction is reverse, use P gear for warming up the car, as no gear change is needed from warming up to driving; if the direction is forward, you can use either N gear or P gear. Below are detailed introductions to car gears: 1. P gear is the parking gear: When the gear lever is in P gear, the transmission is in neutral, but the output shaft is mechanically locked. The car will remain stationary even without pressing the brake, typically used for long-term parking. When engaging P gear, the car must be completely stationary. Do not engage P gear before the car has fully stopped, and always apply the handbrake. On slopes, engage the handbrake before shifting to P gear. 2. R gear is the reverse gear: When the gear lever is in R gear, the transmission output shaft rotates opposite to the engine's direction, allowing the car to move backward. The car must be completely stationary before engaging R gear. 3. N gear is neutral: When the gear lever is in N gear, the transmission gears are idling, the clutch is disengaged, and the transmission load is minimal. N gear is generally used for short stops. Additionally, use N gear when towing the car. 4. D gear is the drive gear: When the gear lever is in D gear, the transmission gears automatically shift between the lowest and highest gears based on factors like speed and throttle opening, following preset shifting patterns. D gear can be used for driving in most situations.

Common Brake Pad Faults?

Common brake pad faults are as follows: 1. Brake pedal not returning: After pressing the brake pedal, the pedal does not return to its original position or returns slowly. This phenomenon is mostly caused by dirt on the wheel cylinder piston. Simply clean the wheel cylinder piston, and ensure that the air in the brake lines and brake fluid is completely bled afterward. 2. Soft brake pedal: A soft brake pedal is very common. Causes include insufficient brake fluid, thinning brake discs and pads, air in the brake lines, or deteriorated brake fluid. The most common issues are deteriorated or insufficient brake fluid. 3. Brake noise: Brake noise mainly occurs when pressing the brake while driving, producing a sharp metal friction sound (very harsh). This may be due to thin brake pads, low-quality brake pads, foreign objects in the brake pads, or rust on the brake discs. Usually, pressing the brake a few more times can alleviate the noise. 4. Brake failure: Brake failure is a very serious issue. Normally, brake failure does not occur unless there are quality issues with the car or faults in the brake system. Brake failure is often related to car quality. When brake failure occurs, first control the direction based on the car's speed, gradually downshift to utilize engine braking, and slowly reduce the speed. When the speed is below 60km/h, consider using the handbrake to slow down (using it at high speeds can cause accidents). 5. Pedal feedback: There are two types of pedal feedback. One is feeling a slight bounce when pressing the brake hard, which is normal. The other is abnormal wear on the brake discs, such as uneven lines. This can cause pedal feedback and reduced braking force. The solution is to replace the brake discs and pads as soon as possible. 6. Hard brake pedal: A hard brake pedal is usually due to a failed vacuum brake booster. The vacuum brake booster has two chambers: one connected to the intake manifold and the other to the external atmosphere. When the engine is running, the intake manifold draws air, creating a fast flow and negative pressure in the negative pressure chamber. The other chamber is connected to the atmosphere. When braking is needed, the pressure difference between the two chambers generates assistance, applying pressure to the brake fluid to create friction between the brake pads and discs, producing braking force. 7. Brake pull: When braking, the steering wheel turns, and the car deviates from its straight path. This fault is caused by uneven braking force on the left and right sides.

Can the ECO Mode Be Kept On for a Long Time?

It is acceptable to frequently activate the ECO mode in a car. ECO mode, also known as Economy Mode, is particularly effective in saving fuel when driving in congested urban traffic conditions. Under ECO mode, the amount of carbon deposits produced by the engine is roughly the same as in normal operating mode, so the ECO mode can be kept on continuously. The primary principle of ECO mode is not overly complex. It involves a comprehensive analysis and judgment of factors affecting fuel consumption during vehicle movement, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal amount of fuel to supply the engine for operation, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine's speed with appropriate gear selection to minimize unnecessary fuel consumption. ECO is an abbreviation, with its Chinese translation representing Ecology (environmental protection), Conservation (energy saving), and Optimization (power). ECO modes are further divided into active ECO driving mode and non-active ECO driving mode. When the ECO indicator light on the dashboard illuminates, it signifies that the vehicle's economy mode is activated. ECO modes are categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the ECO mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active ECO mode does not have a dedicated button; when the dashboard ECO indicator light turns on, it merely serves as a reminder function. ECO automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most vehicles employ the active ECO driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the ECO mode. However, it is unnecessary to enable ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of ECO but also compromise the vehicle's power performance. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed considerations, causing the ECO mode to deactivate automatically. During idle parking or when in N/P gear or manual mode, ECO may also become ineffective. When high torque output is required, such as during hill climbing, the engine's computer prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not function in such scenarios.

What does the EPC light on a car mean?

The EPC indicator light can illuminate in two states: during the power-on self-test and under other circumstances. The power-on self-test is an indication that the vehicle is checking the status of all sensors before driving. Generally, if the engine is not started after powering on, the light will turn off by itself after about 3 seconds. If the EPC light remains on after the vehicle starts or illuminates under other conditions, the main causes may include faults in the engine intake system, throttle issues, fuel system malfunctions, engine problems, ECU control unit failures, or brake light defects. Below is a detailed explanation of the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will alert when the engine intake is obstructed or insufficient. Throttle fault: Carbon buildup is a common issue with the throttle. Additionally, dirt accumulation can affect intake and trigger the indicator light. Fuel system fault: Examples include substandard fuel, deteriorated fuel, or poor fuel atomization. Engine fault: Insufficient engine pressure or issues with the intake valves and other power system components can also activate the EPC light. ECU control unit fault: This may involve interference with the vehicle computer signals or false alarms from the computer. Brake light fault: Situations such as non-functioning brake lights, faulty brake switches, or brake circuit issues. Solutions for when the EPC light illuminates: Troubleshoot intake system issues, use fuel with the appropriate octane rating, clean the throttle, etc. Remove carbon deposits from relevant components. Re-flash ECU-related data. If the EPC light comes on, the owner can first try turning off the engine and restarting it to see if the light remains on. If it does not, there may be no issue, and the EPC light might have been affected temporarily. If the light stays on or frequently illuminates, the vehicle should be taken to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the power system. When sensor data in the system is abnormal, the EPC system will take predefined actions to address the power system issues. Common EPC indicator lights are typically two colors: yellow and red. A yellow EPC fault light indicates the vehicle can still be driven, but it should proceed slowly to a repair point. A red EPC fault light signifies a more serious issue, and the vehicle should be pulled over immediately, with professional repair services contacted. Continuing to drive under such conditions may directly affect the vehicle's core components or driving safety.
