With the progress of the current society, we are using more and more means of transportation, and cars must be mentioned. Not only are they affordable, but they are also fast, so they are very practical. Does the ignition coil have any effect on the fuel consumption of the car? Will the ignition coil get weaker? The symptoms and solutions of the damaged ignition coil package are described in detail by the ignition coil suppliers below.

How does the ignition coil affect the fuel consumption of the car?
The ignition system of a vehicle consists of an ignition coil and a spark plug. Does the ignition coil affect fuel consumption? The truth is so! The ignition coil is responsible for increasing the spark over voltage, and then the high-voltage wire transmits the current to the spark plug to assist the engine to ignite and burn. The ignition coil can also act as a transformer, converting low voltage to high voltage, which is then ignited to power the engine. The ignition coil with good performance provides more energy, the engine burns more fully, and the fuel consumption will naturally be lower when running the same distance. The ignition coil supplier tells you that high fuel consumption is indeed related to the ignition system. If the ignition coil and spark plug are not working properly, it will lead to high fuel consumption and affect the performance of the car, such as car shaking, weak acceleration, rushing, etc., but there are many reasons for the increase in fuel consumption, and we need to analyze specific problems.

Will the ignition coil get weaker?
Ignition coil suppliers tell you that the answer is yes. In the case of weakening, the engine will be difficult to start, the engine speed will rise slowly after stepping on the accelerator, the exhaust pipe will emit black smoke, and the idling will stall. Although the ignition coil is not a wearing part, it will fail if the ignition coil works in a high-temperature environment for a long time. Of course, the ignition coil needs to be replaced after a period of use, otherwise, it will affect the normal operation of the engine. If the spark plug and ignition coil are not replaced for a long time, it will affect the phenomenon of insufficient combustion of the engine, thereby affecting the power of the engine.

Can a bad ignition coil cause transmission problems? What are the symptoms of a damaged ignition coil pack?
If the ignition coil fails, it will also affect fuel consumption. If the ignition coil is faulty or damaged, the engine will lack cylinders. Not to mention the power drop, the fuel consumption will also increase by about 1-2 liters. Once the ignition coil is abnormal, the spark plug will not work, and then the mixture of this cylinder will not detonate. When the vehicle loses a cylinder, the lack of power is natural, and even the car cannot be started in serious cases.

Only one ignition coil is broken, should the other good ones be replaced?
(1) It is best to replace 4 at the same time, because one is broken, and the other 3 are not much better, and they will be damaged one after another, which will affect the driving safety, and even affect the use;
(2) The damage time of the ignition coil is not too long. If there is a problem with one, the others should also fail in a short time. Therefore, the 4s shop recommends that you replace them together to avoid running to the 4s shop many times. waste time;
(3) The ignition coil supplier recommends replacing 4 ignition coils together, and the ignition coils that have not had problems can be reserved for backup.

Is the ignition coil numbered?
some. Depending on the model, the ignition coils have different numbers. According to the provisions of QC/F73-93 "Model Preparation Method of Automobile Electrical Equipment", the model of the ignition coil should be composed of the following parts. Product code: D means ignition Q means coil If there is a letter after DQ, G means dry ignition coil D means ignition coil for the electronic ignition system. Voltage grade code: Use numbers to indicate the rated voltage of the ignition coil, namely 1---12V; 2---24V; 6---6V. Application code: Use numbers to indicate the purpose of the ignition coil, meaning as follows: 1---Single, double-cylinder engine 2---Four, six-cylinder engine 3---Four, six-cylinder engine (with additional resistance) 4--- Six, eight-cylinder engine (with additional resistance) 5---Six, more than eight-cylinder engine 6---More than eight-cylinder engine 7---Non-contact distributor 8---High-energy ignition 9---Other ( Including three, five and seven cylinders) Design serial number: Indicated by numbers Variant code: In the order of A/B/C... For example DQ1244 means the voltage is 12V, used for 4-6 cylinder engines, design Ignition coil with serial number 4

How do I test a 12-volt ignition coil?
(1) Pull out the high-voltage wire at the spark plug, make the high-voltage wire about 1.5 cm away from the car body, and turn on the starter. If there is a blue discharge spark, the ignition coil is good. Otherwise, continue to look down.
(2) Measure the primary current of the ignition coil, adjust the three-meter to DC 10V or 12V, and measure the voltage across the additional resistance. When the distributor is connected, it should be around 4--5V, and the distributor is disconnected. should be 0 volts. If so, keep reading.
(3) Otherwise, check the battery, distributor contacts, capacitors, etc.
(4) Open one end of the two wires of the capacitor in the distributor, and measure the two ends of the capacitor with a three-meter R x1000 resistance gear. The needle should point to infinity after shaking. Swap the positive and negative test leads and measure again. The hands should still point to infinity after shaking. If this is the case, it can be determined that the capacitor is good, and the ignition coil itself is faulty.
(5) In addition, the ignition coil cannot be measured with a shaker, especially for a good ignition coil, it must not be measured with a shaker, because the output voltage of the shaker is very high, and it is easy to break down the insulating layer in the ignition coil. It can be measured with a three-meter, the primary resistance is about 1.1---2.3 ohms, and the secondary resistance is about 4000---11000 ohms. Ignition coil suppliers are kindly reminded that various models are different, the measured values ​​have no reference value, and many interlayer breakdowns and short circuits cannot be measured.

Spark plugs are wearing parts and need to be replaced regularly. If the spark plug is not replaced for a long time, the electrode gap of the spark plug will become larger, which will affect the ignition of the spark plug. If the spark plug is not replaced for a long time, there may be carbon deposits on the electrode of the spark plug, which will also affect the ignition of the spark plug. When using the car, it is necessary to maintain and replace the worn parts on time to keep the car in good condition. When replacing the spark plug, you need to use a professional torque wrench to tighten the spark plug.

Through the above introduction, we have understood the relevant content of the automobile ignition coil. Only by fully understanding the ignition coil can we make the car last longer.
