How many spark plugs are used in a typical six cylinder car engine?

That is true. Normally, a six-cylinder engine has six cylinders, six cylinders have 24 valves, and then only six spark plugs are used.

But there are also cars like Honda.

A cylinder will have two spark plugs for ignition, so it is uncertain.

In general, a six-cylinder car engine usually uses more than 4 spark plugs.

A spark plug is made by passing a slender metal plate through an insulating ceramic. Except for a few models such as the Honda Fit, the rest of the models generally have a few spark plugs in a few cylinders of the engine.

The function of the spark plug is to introduce the high-voltage electricity generated by the ignition coil into the cylinder of the engine, and generate sparks between the gaps between the electrodes to ignite the mixture, so that the engine can work. For this reason, the spark plug is also known as the "heart" of the engine.

How can I tell if I need a replacement?

The first thing is to observe whether the car can start normally when it is cold, and the shaking of the engine. If there is difficulty in starting or abnormal shaking and sound, it is necessary to check and replace it in time.

The second is to remove the spark plug and observe whether there is melting, oil stains or serious carbon deposits on the electrode. If these problems occur, they also need to be replaced.

How often should the spark plugs be changed?

When it comes to replacement cycles, it is necessary to first understand the types of spark plugs. Common spark plugs are divided into six types: copper core spark plugs, platinum spark plugs, iridium spark plugs, iridium platinum spark plugs and double iridium spark plugs.

Among them, copper core spark plugs are the most widely used, and the general replacement cycle is 2-30,000 kilometers.

In general, gasoline cars have several spark plugs in several cylinders, but there are also individual cases, such as the Nissan Bluebird U11 and Honda Fit, which have two spark plugs per cylinder, that is, this four-cylinder engine has 8 spark plugs.

The spark plug is commonly known as the nozzle, and its function is to send the pulse high-voltage electrical discharge from the high-voltage wire (nozzle wire), break through the air between the two electrodes of the spark plug, and generate an electric spark to induce the mixed gas in the gas cylinder.

Types of spark plugs

1. Quasi-type spark plug.

The skirt of the insulator is slightly retracted into the end face of the shell, and the side electrode is outside the end face of the shell, which is the most widely used.

2. Spark plug with protruding edge.

The insulator skirt is long and protrudes beyond the end face of the housing. It has the advantages of large heat absorption, good anti-fouling ability, etc., and can be directly cooled by the intake air to reduce the temperature, so it is not easy to cause hot spot fire, so the thermal adaptation range is wide.

3. Electrode spark plug.

Its electrodes are very thin, characterized by strong sparks, good ignition ability, and can ensure that the engine can start quickly and reliably in the severe cold season, with a wide thermal range, which can meet a variety of purposes.

4. Seat type spark plug.

The housing and screw-in threads are tapered so that they are well sealed without gaskets, reducing the spark plug volume and making it more beneficial to the design of the engine.

5. Polar spark plug.

The side electrodes are generally two or more than two, and the advantage is that the ignition is reliable, and the gap does not need to be adjusted frequently, so it is often used in some gasoline engines where the electrode is easy to ablation and the spark plug gap cannot be adjusted frequently.

6. Surface skip type spark plug: that is, along the surface gap type, it is the coldest type of spark plug, and the gap between the central electrode and the end face of the shell is concentric.

General models follow a cylinder and a spark plug, generally depending on the number of cylinders of the car, individual models also have a cylinder and two spark plugs (for example, the Fit four cylinders have a total of 8).

It depends on the number of cylinders in the engine, one spark plug per cylinder.

The average car has four cylinders and a few spark plugs.

There are several spark plugs in a few cylinders.

Common three-cylinder, four-cylinder, six-cylinder.

There are also eight cylinders, 12 cylinders.

Now the ignition coil of the car is independent, whether it is a four-cylinder or a six-cylinder, the ignition is controlled by the ECU, and there is no difference in terms of the coil.

Four-cylinder cars are four, six-cylinders are six, but there are also four-cylinders that appear eight, for example: Nissan Bluebird U11 and Honda Fit are both four-cylinder, but each cylinder will have two spark plugs. Originally, the service life of the spark plug was very short, and it must be checked or replaced in 6 months, but with the improvement of the spark plug and the ignition device, coupled with some measures for exhaust gas purification, the service life of the spark plug can be greatly improved.

In addition, the performance of the spark plug is also very good, e.g. the wide gap spark plug can improve the exhaust gas purification.

Generally, gasoline cars have several spark plugs in several cylinders, but there are individual cases, such as Nissan Bluebird U11 and Honda Fit have two spark plugs per cylinder, that is, this four-cylinder engine has 8 spark plugs.

Hello: Generally, the four-cylinder car is four, and the six-cylinder is six.

The gasoline car will be written in the book to indicate how many cylinders the car has, and under normal circumstances, the car has as many spark plugs as there are fewer cylinders.

In the ignition system of a spark plug gasoline engine, a high-voltage electric current is introduced into the cylinder to produce an electric spark to ignite the components of the combustible gas mixture. It is mainly composed of a wiring nut, an insulator, a wiring screw, a central electrode, a side electrode and a shell, and the side electrode is welded to the shell.

The performance of the spark plug is also constantly being improved to improve the working quality of the gasoline engine, for example, in order to improve the exhaust purification effect, the use of wide-gap spark plugs (clearance 1 0 1 2 mm); In order to limit the noise of automobile radio waves, anti-interference spark plugs have been developed.

In the past, spark plugs had a very short service life, and car manufacturers required that the car had to be inspected or replaced after 3 000 km (or six months). With the improvement of the spark plug and the ignition device, coupled with some measures for exhaust purification, the service life of the spark plug has been greatly improved.

It is generally stipulated that after 10 000 km of the car has been driven (or every 1 year), the spark plugs must be checked or replaced. The spark plugs of the platinum electrode have a longer service life and generally do not need to be checked and replaced within 100 000 km of the car.

Hope it helps:

Generally, gasoline cars have several spark plugs in several cylinders, but there are also individual cases, such as Nissan Bluebird U11 and Honda Fit have two spark plugs per cylinder, that is, this four-cylinder engine has 8 spark plugs.

The spark plug (Sparkplug), commonly known as the nozzle, is used to send a pulse high-voltage electrical discharge from the high-voltage wire (nozzle wire) to break through the air between the two electrodes of the spark plug and generate an electric spark to induce the mixed gas in the cylinder.

The spark plug is mainly composed of a wiring nut, an insulator, a wiring screw, a central electrode, a side electrode, and a shell, and the side electrodes are welded to the housing.

In short, the engine of the car needs to burn fuel, and the electric spark that ignites the fuel is generated by the spark plug, so the quality of the spark plug affects the working effect of the engine.

Normally, a car has as many spark plugs as there are cylinders, following the principle of one spark plug per cylinder. But there are also special circumstances, some models have two spark plugs in one cylinder, such as Nissan Blue Bird U11 and Honda Fit, these two cars belong to the four-cylinder Bu Yuan, but there are always a total of eight spark plugs. The relevant information about spark plugs in automobiles is as follows:

1. The main function of the spark plug is ignition, the spark plug produces an electric spark to ignite the mixed gas in the gas cylinder, the engine runs the work, and the vehicle also gets enough power. 2. The spark plug parts are small but very important, and Zheng Xian needs to pay attention to maintenance, and regular maintenance can prolong the service life of the spark plug and reduce fuel consumption.

Generally, there are as many spark plugs as there are cylinders in a car, following a spark plug for one cylinder, but there are special circumstances, some models have two spark plugs for one cylinder, such as Nissan Bluebird U11 and Honda Fit, these two cars belong to four cylinders, but there are a total of eight spark plugs.

The work of the gasoline engine is to need a spark plug, the main function of the spark plug is ignition, the spark plug produces an electric spark to ignite the mixed gas in the gas cylinder, the engine runs the work, and the vehicle also gets enough power.

Although the spark plug part is small but very important, it is also necessary to pay attention to maintenance, and regular maintenance can prolong the service life of the spark plug and reduce fuel consumption. Maintenance of spark plugs generally requires regular inspection, regular replacement, and regular cleaning. When the spark plug is found to have carbon deposits, it can be soaked in kerosene for a period of time, gently brushed with a thin steel brush, and the carbon deposits can be removed and dried with compressed air before use.

There are several spark plugs in the car that are not fixed, there are 4 spark plugs in normal conditions, and there are also 8 spark plugs in some models. When replacing the spark plugs, it should be replaced according to the number of spark plugs, and it is not possible to replace only one spark plug.

What should I pay attention to when replacing spark plugs in automobiles? 1. In addition to replacing all the spark plugs, you should also replace the same model and the same brand. If the replacement model is different for different brands of grinding and shaking, it is easy to make the spark plug discharge gap different, and the resistance value of the spark plug will be different, which will cause the car to accelerate difficult, fuel consumption rise, and even cause problems such as jitter.

2. When replacing, you should use a special spark plug socket wrench, you don't need to tighten it when you are in place, as long as the pipeline of the high-pressure ignition cylinder is installed in place, if you press hard, it is easy to cause the reed of the buckle to loosen.

3. When replacing, you must avoid other things falling into the cylinder, even fine dust.

4. The spark plug should also be replaced in the state of cold driving.

Four cylinders are four, six cylinders are six, and there are several cylinders.
