Is it a problem that the ignition line of the motorcycle does not catch fire?

To strangle the closure (also known as the choke) should be pressed to the end in the normal state, the winter cool car should be dialed to the top, about 15 seconds after the car is put in the middle, when the car completes the preheating, return to the normal state to press to the end. This process takes about three to five minutes.

In winter, the weather is cold, so it is easy to catch fire. The climate in the south is warm, and there will be no failure to catch fire, except for the failure of the motorcycle itself. At the beginning of spring in the Northeast, or the beginning of autumn is about to enter the winter season, the temperature is cool and below 0 degrees Celsius in the morning, and the engine oil is condensed, resulting in no fire.

Usually, it is caused by the lack of cylinder pressure due to the decline in oil performance due to cold weather.

Precautions: 1. Do not go to the car wash shop or let others help wash the car, the car wash shop seems to have complete tools and operation specifications, but the problem of poor efficiency in its pursuit of efficiency also exists, and it will also cause the cremation plug and various lines to fail.

2. Be sure to cool down the hot car before washing. Suddenly washing the engine, exhaust pipe and other parts with cold water, the principle of thermal expansion and cold contraction is clear to everyone, which will destroy the oil seal of each part and cause oil leakage in the engine. It will also cause the chrome plating layer at the junction between the exhaust pipe and the engine to peel off and rust oxidized.

3. Headlights, left and right handrails, electric doors, exhaust pipe exhaust ports (it is best to plug them with something), horns, cremation plugs, air filters, batteries and other parts are best not to be washed directly with water, these parts have circuits, which will cause short circuit or leakage after wetting, and the lights are not lit, the horns are not sounding, they are not on fire, and they are weak to drive, so it is best to scrub them with a rag.

It is the ignition in front of the high-voltage packet, that is, the electricity sent by the magneto first enters the igniter, calculates the ignition time, and then provides the low-voltage weak current at this time, and then provides the high-voltage package in a timely manner, and the coil in the high-voltage package induces a high-voltage electricity of about 20,000 volts, so that the spark plug and electrodes jump over. The task of the igniter is to supply power to the high-voltage package at the specified time, the role of the high-voltage package is to induce the low-voltage electricity into high-voltage electricity, and the role of the spark plug is to ignite. The ignition can not withstand high-voltage electricity, high-voltage electricity can only be directly supplied to the spark plug, the order you say is exactly the opposite, look at the circuit diagram or the wiring sequence on the car to know.

1. The battery voltage is lower than 10V, resulting in insufficient starting energy. You can try to start with the wire.

2. The starting motor is seriously worn and the motor is bored.

If the instrument light is normal after the key is opened, the manual transmission car can try to start the cart. Don't rule out the automatic car yourself, if the insurance is complete, call the accident-free rescue tow to the repair shop for another check.

The automotive electronic ignition system is completely different from the mechanical ignition system, it has an electronic control device for ignition, and there are ignition control curves (maps) required by the engine under various operating conditions. The working status of the engine is judged by a series of sensors such as engine speed sensor, intake pipe vacuum sensor (engine load sensor), throttle position sensor, crankshaft position sensor, etc.

Find out the ignition advance angle required by the engine in this working state on the map, and carry out ignition according to this requirement. Then the above ignition requirements are corrected according to the knock sensor signal, so that the engine works at the best ignition time.

The current popular Atkinson engine changes the compression ratio by adjusting the intake time and ignition time to achieve the purpose of fuel saving.

Common reasons why a motorcycle engine has electricity but is difficult to start are:

1.The mixture is too thin. The mixture is too thin when starting the cold car is one of the reasons for the difficulty of starting, in this case, the concentration valve should be opened or the carburetor mixture concentration should be readjusted, and the starting automatic adding device should be checked for LK80T to see if it is working normally.

There is a slight air leakage, which generally occurs at the carburetor and the intake pipe head or at the junction of the left and right crankcases. Apply some soapy water to the joint or joint seam and start it with a few clicks.

2.The spark plug was badly "drowned" by carbon deposits. Both of these conditions weaken the strength of the spark and make it difficult to start. Serious carbon deposits in spark plugs are mainly caused by poor combustion or excessive oil, while "flooding" is caused by excessive mixture.

3.The spark plug electrode gap is too large or too small, which affects the spark strength.

4.Electronic ignition malfunction. It can be judged by comparing it with a peer model electronic point in good working condition.

5.There may be poor contact or leakage in the wiring of the rest of the ignition system.

6.The magneto ignition coil is not working properly.

7.If the ignition system is working fine, but it is still difficult to start, then it is most likely that there is a problem with the oil supply system. In addition to checking whether the oil in the oil tank is mixed with water and whether the oil pipe is smooth, the oil supply system mainly checks the carburetor, and the carburetor often has too many impurities in the float chamber and blocks the main measuring hole, resulting in poor oil supply.

8.Too much carbon deposits in the exhaust port and exhaust pipe, and the inside of the muffler is too dirty, which is also easy to cause difficulty in starting.

Usually the reason why the motorcycle does not catch fire is because the weather is cold, the oil performance decreases, and the cylinder pressure is insufficient.

1. Before starting, check whether the switch of the motorcycle is turned on and whether there is gasoline in the fuel tank.

2. A spark 5 8 mm long can be generated between the spark plug and the cylinder block, and the discharge sound can be heard. At the same time, sparks can also be generated in the millimeter gap between the center and side electrodes of the spark plug.

3. A spark of 5 8 mm can be generated between the spark plug and the cylinder block, but there is no spark between the center electrode and the side electrode of the spark plug, but there is a spark inside the center electrode. Then it is necessary to replace a new spark plug 4, and the length of the spark generated between the spark plug and the cylinder block is only 2 3 mm. At this time, it is necessary to check the gap of the platinum contacts of the broken electric first, and then polish the contacts with a fine abrasive cloth dozens of times, and then wipe the contact surface with a clean rag dipped in gasoline.

Then start the engine several times, and carefully observe the size of the sparks between the contacts of the breaker while starting. If the spark is large, there is a problem with the capacitor that is connected in parallel with the contacts. Replace the capacitor with a new capacitor and it can be started; If the spark is small, it indicates that the high-voltage coil or high-voltage lead-out wire has been broken down.

5. There is no spark between the spark plug and the cylinder block, you need to see if there is a spark between the contacts of the interrupter when starting, if there is a spark, you can deal with it according to step 3. If there is no spark, it indicates that there is a problem with the ignition circuit primary (the low-voltage part).

Hello, it is an honor to answer this question for you, there are three situations when this motorcycle spark plug does not ignite 1. The motorcycle generator flywheel magnet loses magnetism; 2. The voltage of the motorcycle spark plug is unstable; 3. The ignition wire of the motorcycle is in poor contact with the generator. You try to see what kind of situation yours falls into.

I don't know what you said about "ignition coil" refers to the high-voltage package, or the ignition coil in the magneto, if the high-voltage package does not have high-voltage electricity, in addition to its own damage, there may be ignition, magneto stator coil failure, or poor wiring between them, if it is an AC ignition car, it may also be a failure of the flame-out line or the electric door lock, flame-out switch flame-out line short circuit. If the ignition coil of the magneto stator is broken, then it is a problem with the coil itself, and the coil or stator assembly can be replaced.

The ignition coil is composed of the main coil, the secondary coil, the magnetic core, the switching triode and other auxiliary components, the main coil is charged by the battery, the secondary coil is discharged and the spark plug is ignited, and the triode is responsible for switching. The charging time is controlled by the battery voltage and engine speed to ensure that the energy of each charge is consistent, the ignition coil has two kinds: 3 wires and 4 wires, 3 wires are positive and negative for the power supply, and the switch controls the ECU instruction, and the 4 wires have an additional ignition detection line, which can detect whether the spark plug is ignited and whether there is a discharge current in the secondary coil.

To put it simply, the ignition coil is a transformer, that is, the voltage of tens of volts is raised to tens of thousands of volts, but the voltage input to the primary coil is provided by the electronic ignition.

2: The reason why the ignition coil burns out.

Mainly the aging breakdown of the insulation layer or the damage of the switching triode, the large spark plug gap will lead to the main coil load, large heating, fast aging of the insulation layer, small spark plug gap leads to large discharge current of the secondary coil, fast heating, fast aging of the insulation layer, the assembled ignition coil may have poor durability of insulating materials, large internal resistance of the coil and fast heating, and the life of the transistor will be shorter if the quality is not high.

If it is always burned out, and it burns out soon after replacement, and why?

Let's take a look at the problem of the generator first, if the power generation is too high, the load of the ignition coil is too heavy, it is easy to burn out, but if the power generation is too high, then the body electrical appliances, such as light bulbs, will often be damaged; Of course, the quality of the accessories is not ruled out, so it is best to measure the power generation first.

If the spark plug gap is too large, adjust the gap or replace the spark plug.

The quality of gasoline is not good, try to change to high-grade gasoline.

If the compression ratio of the cylinder is wrong, adjust the compression ratio.

If there is a program failure in the computer version, you can go to the repair shop and use the computer to test the car and clear the wrong information. If it doesn't work, it may be that there is a problem with your car's transmission.

The power supply voltage is unstable.

The resistance of the high voltage is abnormal, replace the high voltage line.

There is a short circuit in the secondary.

The ignition coil is overheated due to the high primary current of the ignition controller.

It does not work well when subjected to high temperature and high pressure waves.

There is a small chance that it is a problem with the coil itself, so you can try a different brand.

The ignitor manifold does not work well.

Motorcycles are a very convenient means of transportation, but they will inevitably encounter various failures after long-term driving. One of the problems that often arises is that the ignition is not ignited, which is very troublesome for people who need to use a motorcycle for daily travel. Motorcycle ignition failure can be caused by a variety of reasons, here are a few possible causes and solutions.

1. It may be a leak of the cylinder barrel piston door or valve. If there is a leak in these critical areas, the motorcycle will exhibit unstable idling, making it difficult to start the vehicle. The solution to this problem is to replace it with a new piston ring to enhance the tightness between the parts.

2. The carburetor adjustment ratio is out of balance, which will also lead to ignition difficulties. If the carburetor adjustment ratio is too small, resulting in insufficient oil output, the energy released cannot start the engine. In this case, the owner can increase the proportion of gasoline in the mixture by turning the carburetor nut through the thick pants, and check the color of the central electrode of the fire plug and adjust it appropriately.

3. Excessive spark plug clearance will also reduce the ignition ability, resulting in difficulty in starting. At this time, you can take out the spark plug and use small pliers to adjust the spark plug gap slightly to make the flame easier to focus and increase the success rate of ignition.

Most owners now use EFI motorcycles, which use a microcomputer to control the fuel injection device to inject fuel into the cylinder according to the engine load. Compared with traditional carburetor motorcycles, EFI motorcycles are more mature and less prone to failure. If the ignition difficulty of the EFI motorcycle, it may be due to insufficient fuel, power, problems with the electronic control system, spark plug stuffy oil and carbon deposits, etc.

Car owners need to check the oil circuit, lines, etc. step by step to understand the specific situation and carry out timely maintenance.

There are many reasons why the motorcycle ignition cannot be ignited, if the electric start and foot start are not ignited, you can find the passport reason from the three necessary conditions for the motorcycle engine to start, these three basic conditions are:

1.combustible mixtures of appropriate concentrations;

2.Accurate and strong high-voltage electrical sparks;

3.Good cylinder compression.

As long as these three basic conditions are present, the motorcycle engine can be started, and these three basic conditions involve multiple parts and a variety of possibilities, which need to be checked in combination with symptoms.

Check whether the gasoline and fuel supply are normal, and whether there are any blockages or other problems with the air filter, carburetor or throttle nozzle, exhaust pipe, etc.

Check whether there is enough gasoline in the fuel tank, whether the quality of the gasoline oil is not good, and whether there are problems with the fuel pump or tank switch, gasoline filter, etc. Check whether the air filter, carburetor or throttle nozzle, exhaust pipe is blocked, clean or replace the air cleaner, clean the carburetor or throttle nozzle, if it is a carburetor, also check whether there is a problem with the carburetor's mixing ratio, oil level, oil needle, damper, etc. In the case of EFI, also check whether the sensors related to the ignition system and their wiring are faulty.

Check that the spark plug is normal and that the electrode clearance of the spark plug is correct. If there is no high-voltage electricity or the high-voltage electricity is obviously broken or the fire is weak, it is necessary to check whether the spark plug, high-voltage bag, igniter or ECU, magneto, ignition switch, electric door lock, flame-out switch (if any), etc. are damaged, and whether the circuit between these parts is open or short-circuited, and whether the plug is loose and virtual. Check whether the parts of the ignition system are damaged, or if there is a problem with the parts of the gas distribution system, the ignition time is incorrect.

Check whether the cylinder compression is good, and whether there is any air leakage in the valves and intake pipes.

Check whether the cylinder block, piston and piston rings are worn, or the cylinder pressure is low due to air leakage such as cylinder gasket and spark plug, whether the valve clearance is too small, or the valve is not closed tightly due to carbon deposit, wear, ablation and other reasons. The intake pipe between the carburetor or throttle and the engine, as well as other hoses related to the engine, carburetor or throttle, secondary make-up system, and negative pressure tank switch (if any), etc., may also cause the motorcycle to fail to ignite.
