Is the spark plug of a car hitting, what is the engine, what can hit it?

The spark plug is said to be the spark plug ignition pole penetrated, resulting in a bad ignition

The main function of the spark plug is to point into the mixture in the cylinder, if the spark plug is damaged and does not work, the mixture in the cylinder will not be able to burn, then the cylinder will not work, and the engine will have a jitter fault phenomenon. The vehicle will have a lack of power and increase fuel consumption. In severe cases, the engine will stall, and the vehicle will break down and cannot drive normally.

Therefore, the spark plugs need to be checked and replaced regularly. Generally, the pole gap of the spark plug is checked, and if the pole gap is less than 1mm, the spark plug needs to be replaced. Because the pole clearance of the spark plug is too large, the ignition amount will be insufficient, the vehicle will also have jitter and insufficient power, and the carbon deposit in the engine cylinder will also increase.

Hope, thank you!

The spark plug is a component with a high failure rate, which has a great impact on the normal working condition of the engine, and the saving and waste of fuel. Therefore, it is common to see that the car after replacing the spark plug is easier and more powerful than before, the fuel consumption is reduced, the smoke exhaust is clean, and there is no black smoke.

There are a few reasons why a car needs to have its spark plugs replaced:

a. Oil accumulation appears in the spark plug. Touching (or looking closely at) the spark plug by hand will reveal oil stains. Most of the reasons for this failure are that the engine has been started for a long time without ignition, that is, the spark plug has been injected with oil but the oil has not burned.

In this way, the oil layer covers the spark plug electrode and it is more difficult to start. Therefore, experienced drivers should not step on the accelerator too much when starting to prevent the engine from starting with stuffiness.

b. A layer of deposited black carbon appears in the spark plug. Most of the causes of failure are caused by the high concentration of the engine's oil supply mixture or the combustion of the internal lubricating oil. The occurrence of carbon deposits can easily cause the engine to intermittently fail and make it run ineffectively.

The engine sometimes feels weak, often due to this.

cThe spark gap is too large, resulting in a high breakdown voltage and a long time. Therefore, when running at high speed, it is easy to have individual cylinders that are out of fire. This fault is easy to solve, but it is required to adjust the gap at high speed and measure it with a special tool.

Based on the above four reasons, we are required to reasonably adjust the electrode clearance of the spark plug in the engine ignition system, clean the spark plug on time, and do a good job of maintenance

Remove the spark plug from the engine, soak it in acetone (a chemical solvent) or kerosene for a period of time, and then gently scrub it with a fine steel brush until the carbon deposit is clear, then dry it with compressed air and put it back in use.

Fault example: Fault phenomenon: the spark plug works poorly, and the high-pressure spark is weak.

Solution: Remove the spark plug and soak it in gasoline for a while, use a paper clip or pin as a self-made special scraping tool, scrape off the carbon deposits in the spark four hot chambers, re-wash it and try it out, and the fault is eliminated.

Simple analysis of the cause of the fault: too much carbon deposition leads to different degrees of conductivity between the central electrode and the spark plug housing, resulting in a shunt current, which conducts part of the ignition energy and weakens the ignition spark. If the contamination is severe, ignition sparks may not occur.

The ignition of a gasoline engine is not only a spark plug, it is a non-argumentative or often accurate ignition system. Typically, the system consists of a crankshaft position sensor, an igniter, a high-voltage ignition coil, and a spark plug, which in a very different sense ignites according to the crankshaft position. Taking motorcycle Pinai engine as an example, the crankshaft position is determined by using the convex sleeve on the magneto stator and the trigger coil (crankshaft position sensor), when the engine rotates every time, the trigger coil provides an ignition signal for the igniter, and the igniter can generate an ignition signal.

<> ignition signal is transmitted to the ignition coil (high-voltage ignition coil), which is then pressurized by the high-pressure bag and sent to the spark plug to generate a spark, which starts the engine smoothly under the mixed action of combustible gas and high pressure in the cylinder. The ignition sequence on the car takes the four-cylinder engine as an example, it is 13-24 alternate ignition, and the current model is mainly controlled by the computer version of the distributor that alternately ignition between the cylinders, the general principle is: the intake and exhaust of the crankshaft drive the camshaft through the timing chain, and the ignition coil is completed by the spark plug during the compression process.

The spark plug controls the time and ignition distributor through the computer version, which is considered to be the nemesis of the engine crankshaft, and the power transmitted by the main bearing for the spark plug is high voltage, which is raised from the low voltage electricity of the ignition coil (transformer) to the high voltage of about 20,000 volts, and then transmitted to them on demand through the distributor. The job of the spark plug is **. When the piston moves to the TDC, the intake valve and exhaust valve of the cylinder are closed at the same time, and the spark plug emits a high-pressure spark in time to ignite the compressed mixture in the cylinder, and the mixture immediately deteriorates and expands, pushing the piston to drop rapidly to do work.

The piston drives the engine crankshaft through the connecting rod to generate power. The top of the spark plug has positive and negative poles, through which high voltage emits sparks. The gap between them is generally required to be about two millimeters.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

When the spark plug is working, as long as the engine is started, the engine will ignite the spark plug, and the spark plug is an important part of the engine ignition system, so we must pay attention to the problem of vertical surface in this side. First of all.

It is the ignition coil that ignites the engine spark plug, and the ignition coil can release high pressure, and at this time you can give enough energy to the spark plug.

It is the ignition system that ignites the spark plug of the engine when the car starts.

A combustion system that ignites the spark plug of the engine when the car is starting.

The spark plug is a component in the braking system of the car, if the spark plug is broken, it will also affect the braking effect of the car, and it will also affect the normal driving of the car.

The spark plug is a component in the engine that plays the role of transmission. If it breaks, it can cause difficulty in starting, low power, excessive exhaust gas, increased fuel consumption, and frequent short circuits.

The spark plug is a ** point in the car, that is, it can start normally only when it has the power of the spark plug when it starts. If the spark plug is broken, then it will consume fuel and will not be easy to start. High consumption of gasoline. The motivation will also be weakened.

The spark plug is the ignition component of the car, and it is also the control ignition system, which will not start the car after it is broken, and there will also be excessive carbon deposits, exhaust gas exceeding the standard, affecting the emission of the car.

In fact, it is a part that controls the gasoline spraying of the car, and if this part is broken, the car should leak oil, and even affect the power operation of the car.

It's just an important part of the car. If the spark plug is broken, the car will go into idle state after starting, and the temperature will suddenly become high, and the car will shake particularly violently.

The spark plug is an important part of the ignition system in the gasoline engine. If the spark plug is broken, the car will not catch fire and will not work.

The spark plug is an important part in the car, and the impact on the car is great, if it is broken, the car will not be able to operate.

The spark plug in the car is a very critical part of the car starting. If the spark plug is broken, the car will not start.

The function of the automobile spark plug is to break down the air between the two electrodes of the spark plug with the pulse high-voltage electric discharge sent by the high-voltage line, and generate an electric spark to induce the mixed gas in the gas cylinder. Today, let's take a look at how the spark plug of a car works.

There are many types of spark plugs, such as quasi-type spark plugs, edge protruding spark plugs, electrode type spark plugs, seat type spark plugs, deformed spark plugs, and surface jump fire type spark plugs.

A car's spark plug is made from a long, thin metal plate that passes through an insulating ceramic material. The lower part of the insulator beam is surrounded by a metal shell, which is screwed on the cylinder head. At the bottom of this metal shell, a welding electrode is used to form a grounding effect with the car body.

Then the high-voltage current from the distributor will pass through the ** electrode and be discharged at the end discharge gap. At this point, the spark plug uses the vertical spark to burn the mixture, and the engine gets the energy and outputs the power.

The working environment of the spark plug is extremely harsh. In the process of work, the alternating frequency of quenching and heating will occur, which is not something that ordinary materials can cope with, and it is necessary to ensure absolute insulation performance. Therefore, the material requirements for spark plugs are very strict.

Next, let's talk about the contraindications for the use of spark plugs. In the process of using the spark plug, avoid long-term unclean carbon deposits, you can use Yu Jianmin for a long time, and each spark plug has its own life. Do not descale at will.

If descaling is not done properly, it can cause spark plug damage. Do not distinguish between hot and cold, and the selection of spark plugs should tend to be medium or cold to improve the ability of spark plugs to resist oil pollution. Do not install too tightly.

If the installation is too tight, it will cause the engine to work abnormally.

We should develop the awareness of regular maintenance of spark plugs. If there are gray stripes on the tip of the insulator, the spark plug with this stripe mark has leaked air and should be replaced with a new one in time. If the tip of the insulator is shattered, it may cause the engine to knock and burn, and the spark plug should be replaced immediately.

If the spark plug has oily deposits, the air filter and ventilation should be checked for blockages, and if there is black deposits, the engine speed should be increased.

That's all for me.

The spark plug of the car is an electric current generated after the electricity is applied, which causes the spark to ignite it instantly, and then the engine starts.

The spark plug of the car should be after the car brigade is dismantled or ignited, the spark plug can control the position of the engine and some voltage of the engine. It can also compress gasoline to a certain extent.

It is the use of high-voltage wires, release electric shock, and use the motor through the spark plug to generate a spark to attract mixed gas, so that the spark plug works.

This is discharged using pulsed high pressure, and then the work is carried out, ignition is carried out, and the gas cylinder is ignited.

The working principle of the spark plug is: the electric plate of the spark plug ignites the mixture in the cylinder through repeated and continuous power generation ignition, and at this time, the other parts of the ignition system generate a timing of high-voltage electrical pulses to form a spark and produce the energy required to provide the power output of the engine.

Spark plugs play a vital role as the end component of the engine ignition system. The calorific value of the spark plug refers to an index of the heating and heat dissipation capacity of the spark plug, and the amount of heat emitted by itself is called the calorific value.

The calorific value of the spark plug includes nine numbers of 1 9, of which 1--3 is the calorific value of low and medium nuclear sales, 4--6 is the medium calorific value, and 7--9 is the high calorific value. The original spare parts spark plug calorific value is generally three kinds, can dissipate a large amount of heat is called cold spark plug, that is, high calorific value spark plug, cold spark plug (high calorific value) insulator skirt is relatively short, because the heat dissipation path is relatively short, heat dissipation is relatively more, so it is not easy to cause the temperature of the central electrode to rise. The relatively small heat dissipation is called a thermal spark plug, that is, a spark plug with a low calorific value.

The insulator skirt of the thermal spark plug (low calorific value) is longer, and when the temperature in the cylinder is evenly arranged, the longer the skirt, the larger the heating area, and the longer the distance of heat conduction, so there is less heat dissipation and the temperature rise of the center electrode is higher. Generally speaking, spark plugs with low calorific value are more suitable for low-power engines with low speed and low compression ratio, while spark plugs with high calorific value are suitable for high-power engines with high speed and high compression ratio. The higher this value, the more "cold" it is, and the smaller this value, the smaller the heat dissipation of the spark plug, and the more "hot" it is, depending on the mixing temperature in the cylinder and the design of the spark plug.

No. It is ignited by a power generation that is repeated by an electric board.

Basic structure of a spark plug:

The insulator must have good insulation and thermal conductivity, high mechanical strength, and be able to withstand high temperature thermal shock and chemical corrosion. The housing is made of steel. The dimensions of the hexagonal threads of the housing have been incorporated into the ISO international standard.

The spark plug electrode consists of a center electrode and a side electrode, and the spark gap between the two is the spark gap. The size of the clearance directly affects the starting, power, working stability and economy of the engine. A reasonable gap is related to the ignition voltage.

The electrode material must have good resistance to electrical erosion (spark ablation) and corrosion (chemical-thermal corrosion), and should have good thermal conductivity. Between the central electrode and the wiring screw is a conductor glass sealant, which must be able to conduct electricity and withstand the high pressure of the combustion of the mixture, while ensuring its tightness.

The role of the spark plug is to create an electric spark that is used to ignite the gasoline in the engine cylinder. Spark plugs are divided according to the electrode material, including nickel alloy, silver alloy and platinum alloy.

The structure of the spark plug is made of a slender metal electric plate through a ceramic material with insulating function, and there is a metal shell around the lower part of the insulator, which is screwed on the cylinder head in a screw way, and an electrode is welded at the bottom of the metal shell to form a grounding effect with the automobile body. In addition, the ends of the electrodes** must be separated by a small discharge gap. The high-voltage current from the distributor will pass through this ** electrode to conduct electricity, and then discharge in the discharge gap at the bottom end, at this time the spark plug plays a role to generate an electric spark and ignite the mixture, and the engine will get power and output power.

It can be seen that the spark plug is used to ignite the gasoline mixture gas in the engine cylinder, and works under the bad bar of high temperature and high pressure, and is one of the wearing parts of the gasoline engine, which plays a very important role in the operation of the engine, and whether the car is fuel-efficient or not, whether the engine runs smoothly or not, has a great relationship.
