How to identify spark plugs: Popular topics and shopping guides on the entire network
Recently, car maintenance and accessories purchase have become hot topics, especially spark plugs, as the core component of the engine, and their identification and replacement methods have attracted much attention. This article will combine the hot contents of the entire network for the past 10 days to analyze the identification methods, purchase points and common problems of spark plugs in detail, helping you to easily cope with vehicle maintenance needs.
1. Basic functions and importance of spark plugs
Spark plugs are key components of the ignition system of gasoline engines and are responsible for igniting the mixture, which directly affects the engine's power, fuel economy and emission performance. If the spark plug is aging or damaged, it may lead to difficulty in starting, increased fuel consumption or even engine failure.
2. How to identify the model and specifications of the spark plug?
The model of the spark plug is usually composed of letters and numbers, and the encoding rules of different brands vary slightly. The following are the common brand model identification methods:
| brand | Model example | Meaning Analysis |
|---|---|---|
| NGK | BKR6E-11 | B=thread diameter 14mm, K=hexagonal side length 16mm, R=with resistance, 6=heat value, E=thread length 19mm, 11=gap 1.1mm |
| Bosch | FR7DC+ | F=thread diameter 14mm, R=with resistance, 7=heat value, D=thread length 19mm, C+=platinum electrode |
| Electric installation | IK20 | I=iridium electrode, K=thread diameter 14mm, 20=heat value |
3. Comparison of material and performance of spark plugs
The lifespan and ignition performance of spark plugs of different materials are significantly different. The following is a comparison of mainstream materials:
| Material Type | Lifespan (km) | Ignition performance | Applicable car models |
|---|---|---|---|
| Nickel alloy | 20,000-30,000 | generally | Economy car |
| Platinum | 40,000-60,000 | excellent | Mid-to-high-end cars |
| Iridium | 60,000-100,000 | Excellent | High-performance car |
4. Quickly determine whether the spark plug needs to be replaced
If the following symptoms occur, it is recommended to check or replace the spark plug immediately:
1. Difficulty in starting the vehicle or jitter at idle speed;
2. Acceleration weakness and fuel consumption increase significantly;
3. The engine fault light is on;
4. The spark plug electrode has severe carbon deposits (black or oily stains can be seen by the naked eye).
5. Things to note when purchasing spark plugs
1.Match original parameters: Refer to the vehicle manual or original spark plug model first.
2.Pay attention to calorie value: Too high calorific value can easily accumulate carbon, and too low can easily lead to knocking.
3.Choose a regular channel: Avoid buying counterfeit and shoddy products, recommend official flagship stores or authorized dealers.
6. Frequently discussed issues across the Internet
1.Can the spark plug be replaced by yourself?Basic tools and operation knowledge are required, otherwise professional technicians are advised to operate.
2.Can spark plugs be mixed with different brands?Not recommended, performance may be affected by parameter differences.
3.Do I need to match the computer after replacement?Most models do not need it, but some high-end cars need to reset the ECU.
With the above structured analysis, you can easily identify the spark plug model and make reasonable choices. Regular inspection and replacement of spark plugs is a key step to ensure the healthy operation of your car!
