There is no spark between the high pressure and the spark plug

What does it mean to graft a high-pressure cap with a spark plug? If the spark plug is inserted into the high-voltage cap to test the fire, the metal part of the spark plug should be placed on the unpainted metal of the engine shell or frame, if the high-voltage spark is scattered or scraped at this time, it may be caused by the leakage of the spark plug, high-voltage cap or high-voltage wire.

Hello, happy to answer your <>

Spark plug flashover fault diagnosis process 1, check whether the electrical accessories such as instruments and wipers are blocked from normal operation 2, check the working power supply of the ignition coil, and screw the ignition switch to the past" off ", disconnect the ignition coil wire right connector EN19 (EN20), and screw the ignition switch to" on "Position, ignition coil 3, measure the primary resistance value of the ignition coil, turn the ignition switch to the "off" position, the ignition coil harness connector EN19 (EN20) The standard value between the No. 1 terminal and the No. 2 terminal of the ignition coil is normal 4, measure the secondary resistance value of the ignition coil, rotate the ignition switch to the "off" position, disconnect the ignition coil harness connector EN19 (EN20), measure the resistance value between the secondary terminals of the ignition coil, The standard value is the reason why the resistance is not splashed by the spark plug.

In this case, it is best to go to a professional place for repair, which is the best solution, so as not to have a more serious failure or danger, you can check whether there is a flashover, so that you can also judge which place is the cause.

At this time, you should check the spark plug in time, and be sure to pull out the high-voltage line, and then determine the condition of the engine, you can also go directly to the 4S shop or a professional repair shop for overhaul and maintenance.

Unplug a high-voltage wire away from the spark plug. At this time, the accelerator, if the engine shakes, after plugging in the high-voltage line, the engine does not shake, indicating that the cylinder is working normally. On the contrary, there is no change in the engine sound when refueling, indicating that the cylinder is not working.

The high-voltage line should be checked for flashover, spark plug clearance, damp, oily or excessive carbon deposit.

You can go to the repair shop to solve it, and you can also use the elimination method, and you should pay attention to judging the root cause of the problem, and you should also pay attention to the carbon deposit problem, and also pay attention to regular inspection and maintenance.

Hello subject, the spark plug is ignited all the time, and the part that only works when it starts is the starter. Gasoline engines require spark plugs for each cylinder mixture to ignite. That is to say, at different speeds, the car engine needs a spark plug to ignite the mixture every time it does work.

If the engine speed of a car is 1,000 rpm, then each spark plug needs to do work 500 times a minute.

The working principle of the spark plug is to ignite the mixture in the gas cylinder through the arc generated by the voltage between the electrodes to maintain the normal operation of the engine. Generally speaking, the ignition system of most gasoline engines needs to provide high voltage to the spark plug to ignite the mixture at regular intervals when the engine is doing work.

There are also some cars that do not need spark plug ignition, and these cars are diesel cars, because diesel cars use compression-ignition engines, which rely on the high temperature and high pressure of the cylinder charge at the end of compression to cause spontaneous combustion of the mixture. Compression-ignition engines are widely used in cars, trucks, locomotives, ships and generators, and are mostly turbocharged, so the size and mass of the engine's output per unit time are relatively small. Please adopt thank you!

The ignition coil will release a high-pressure fire, which will release a spark through the spark plug to ignite the compressed atomized gasoline and air mixture in the combustion chamber of the engine cylinder, and push the engine piston to do work.

The spark plug is not igniting all the time, the crankshaft of the four-stroke engine rotates twice to do work, and the work is ignited once.

Whether the spark plug of the car starts to ignite once and turns off immediately, or does it keep igniting.

Summary. In the case of spark plug ignition, the ignition is carried out inside the combustion chamber, when the upper fulcrum of the cylinder is compressed.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

In the case of spark plug ignition, the ignition is carried out inside the combustion chamber, when the upper fulcrum of the cylinder is compressed.

The low-voltage circuit and the high-voltage circuit in the ignition system can share part of the circuit. True or false.

Spark plug ignition occurs at () moment.

a. The low-voltage circuit is turned on.

b. Breaker contact opens.

c. The ignition switch is disconnected.

d. Breaker contacts are closed.

Master, are you still there?

It should be that when the breaker contacts are opened, the spark plug starts to ignite.

This involves the internal working state of the computer board.,You should be a theory exam.。
