What to do if it is difficult to ignite an EFI motorcycle in winter

The following three aspects should be paid attention to when motor vehicles are difficult to start in winter:

1. Check the status of the battery.

Generally, the difficulty of starting the car in winter is mostly caused by the loss of battery power or the expiration of the battery service life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out.

Do not park the vehicle for a long time in winter, generally park the vehicle for a week to drive out for a circle, so that the battery power can be effectively replenished.

2. Change the appropriate engine oil.

In winter, as the temperature drops, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. If it is difficult to start, check whether the oil label is incorrect.

The oil label consists of two parts: grading and viscosity specification. At present, most of the engine oils on the market use SAE and other grades to mark the viscosity, SAE is the abbreviation of the English "American Society of Automotive Engineers". For example, in 5W-40, "W" means winter, which refers to the low temperature viscosity grade of the engine oil, and the higher the number in front of it, the better the low temperature fluidity of the engine oil, which means that the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start.

3. Replace the spark plug in time.

After a few years of use, spark plugs are prone to cause problems such as carbon deposition, leakage, excessive clearance, and ablation, which will cause difficulties in car ignition, cold start, and even hot engine start, and often need to be ignited multiple times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, weak, shaking, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it in time.

Not only is the motorcycle not good in winter, all motor vehicles have this problem The temperature difference in the season is illuminated, change to a higher number of antifreeze engine oil, to buy a special antifreeze engine oil for motorcycles, the effect must be better, if possible, push the motorcycle into a heated house to keep the preheating state.

1.Placing the motorcycle in a warm place and in a heated room can solve this problem very well.

2.If there is no condition to put it in a place with high temperature, then, the motorcycle must be equipped with a starting lever to help start, if there is no starting lever, it can only be pushed by manpower to solve this problem.

3.Using high-quality antifreeze engine oil can also ensure the viscosity of the engine oil, which is very convenient to use.

In winter, the temperature is cooler, and the engine is more viscous. The battery is insufficient (the temperature of the lead-acid battery drops by 1% for every one degree of decrease), at this time, the starter needs to pay considerable force to drive the crankshaft to run, that is to say, the battery should be discharged in large quantities, when the power is not enough, the voltage drop relay releases the power off to produce a sound, and the voltage rises after the power is off, and the relay is engaged in such repeated actions to produce a sound, and it is difficult to start the fire at this time. The solution is to change the antifreeze oil, still close the choke to thicken the mixture, and it will start smoothly (but make sure that the power is sufficient).

Whether it's EFI or carburetor, the motorcycle is not easy to start in winter. 1. It is difficult for the motorcycle battery to be discharged in cold weather, and the available power is greatly reduced; 2. In winter, the temperature is low, and the oil is thick, which affects the rotation of the engine; 3. If it is belt driven. In winter, the belt will freeze and stiffen, which will also affect the starting effect.

The solution to the problem that the EFI motorcycle does not catch fire in winter is:

1. Observe the fault warning light of the electronic control system: if there is an alarm, it means that the electronic control system is faulty.

2. Pay attention to the fuel gauge or fuel level warning light: if it is not enough, fill up the fuel before starting the engine.

3. Check the ignition system: pull out the high-voltage lead at the end so that it is 5-7mm away from the cylinder block, press the start button, turn the engine and the starting device together, and make the spark plug jump into the fire.

The impact of EFI motorcycles parked at minus 20 degrees for a month.

According to the characteristics of the better starting performance of the EFI motorcycle at low temperature, the motorcycle at minus 20 degrees can be completely touched and ignited smoothly, so this situation does not have much impact on the EFI motorcycle.

However, there will be great uncertainty about whether it can be started normally after a month of parking. Because this is no longer a single performance of EFI motorcycles, but more depends on the normal maintenance and parking skills of the motorcycle.

The reason why the EFI motorcycle can be triggered at a touch is not only its own excellent performance, but also from the strong current driving force of the battery. According to the current specifications of motorcycle batteries, they are lead-acid batteries, the biggest advantage of this battery is that the cost is relatively low, but the external ambient temperature will have a greater impact on its working state.

In winter, EFI motorcycles are generally better started than carburetor motorcycles, as long as the car is kept in good condition, it can generally start smoothly. Before entering the winter, you can check the condition of the oil, if the local winter temperature is very low, you can change the oil suitable for winter use, such as 50W W-40 or 0W W-40, etc., such oil has better low temperature resistance, and it is not easy to be too viscous at low temperature, and it is not easy to increase the resistance of engine operation. In addition, keep the battery power sufficient, the spark plug is in normal condition, the high-voltage electric spark is strong, and the cylinder pressure is not low, so that it can generally be used normally in winter.

Of course, if the temperature is too low in winter, no matter how good the condition of the car is, it will always increase the difficulty of starting, which cannot be completely avoided.

The temperature of about minus 15 degrees or even lower, you can choose indoor storage (the advantage of garages in cold areas), at this temperature, including gasoline vehicles (including EFI motorcycles), there are cold start difficulties, and the battery has nothing to do with whether the EFI has nothing to do with it, and the oil has nothing to do with it, except for some low-temperature resistant brand cars and motorcycles, even if the temperature is lower, this part of the car is not affected,

As long as the EFI motorcycle has normal performance, it is easy to start in winter and summer, and the various sensors on the car will adjust the concentration of the mixture appropriately through the temperature, and if it is not easy to start in winter, it is a fault.

Motorcycles may not catch fire in winter for the following reasons

The battery is aging and out of powerIn winter, the temperature is relatively low, and the engine has not been warmed up; Spark plug failure, spark plug so long time caused by performance degradation; There may be no gasoline in the tank, etc.

The scooter can not be ignited in winter, mostly because the temperature is too low, at this time the motorcycle can be supported, the rear wheel is in a suspended state, try to use the key to ignite, if the fire is not ignited, the key will be screwed to the position of the power on, the wheel can rotate freely after hanging the neutral gear, and then hang on the first gear, at this time with your hand on the rear wheel of the motorcycle to dial back, pull a few more times to ignite.

Be sure to pay attention to safety when using this method, and if you don't pay attention to the rear wheel when you pluck it with your hand, you will get your hand stuck in it. Due to the very cold winter, the viscosity of the oil in the motorcycle is relatively large, and when the temperature is low, it will cause the oil to condense into lumps, so it is difficult to start the motorcycle.

Kick the pedal of the motorcycle a few times before starting, and do so by mixing the viscous oil inside with external force, and the starting key will be on fire.

Pay attention to the maintenance of EFI motorcycles in winter.

1. It should be maintained in accordance with the provisions of the manufacturer's instruction manual. For example, regularly change the engine oil (generally 1000 km), gear oil (5000 km), clean or change the air (5000 km), check the brakes regularly, or replace the brake pads, replace the spark plugs regularly, check the battery capacity regularly, etc.

3. Try to flush as little as possible, and pay attention to the wiring harness when flushing, otherwise it will not start due to moisture short circuit. Do not rinse without cooling.

Damage to the oil pump of the oil supply system or failure of the injector; Exclusion method: When opening the car key, if there is no sound of the oil pump running, check whether the fuse of the EFI system is blown and whether the oil pump relay is damaged, and replace the fuse or relay if necessary. If there is a running sound, remove the injector (keep the connector connected), press the start button, see if the injection condition is well atomized, and replace the injector if necessary.

EFI motorcycles can't catch fire in winter because the temperature of the engine is too low, and the temperature of the nozzle is also very low, and the electric ignition can't reach the ignition point of the fire, so it's difficult for the EFI motorcycle to catch fire in this winter.

When the weather is cold, the cold starting performance of the motorcycle will inevitably be adversely affected, when the temperature is low, the mixed air atomization is not good and it is not easy to ignite, and the cylinder pressure is easy to be lower, which is not conducive to the starting performance of the cold car.

Before entering the winter, the car should be maintained, such as changing the winter oil, and check whether the valve clearance is too small or the closure is not strict due to carbon deposits, wear, ablation, etc., whether the cylinder pressure is low due to wear and tear of the cylinder block, piston and piston ring, whether the spark plug is bad, whether the intake pipe and other hoses are aging and slight air leakage, etc., most of the bad starts when it is cold are related to these conditions.

In addition, when the cold car starts, the damper should be pulled directly, and the damper should be pulled directly to the end, not only half, nor wait for many times to start and then pull the damper, which may be more difficult to start. Generally, do not tighten the accelerator when starting a cold car, but it is not absolute, and it should be flexibly mastered according to the actual situation, and there are differences between cars. Before the cold start, you can also not open the key, pull the damper and start with your feet to step on a few, and then open the key to start, which will also help with cold start.

Summary. The hot car of the air-cooled EFI vehicle is not good to catch fire, which is caused by the leakage of the EFI injector of the throttle, and the mixer is too thick.

What is the reason why the EFI motorcycle does not catch fire at high temperatures?

Dear, hello, I have seen your question, it takes time to organize the answer and type, please wait patiently for a while, I am giving you the best answer and advice according to your question, please understand, I will reply to you within three minutes, thank you very much for <>

The EFI motorcycle can't catch fire at high temperature, it's because your vehicle's water temperature sensor is broken, and the signal to the computer is the high temperature of the vehicle, so the computer limits the ignition, in fact, the sensor is broken, and the signal given is too high. Unplug the water temperature sensor and it will ignite normally. Once the fault is identified, it is OK to replace the sensor.

Clean the throttle and fuel injector, pay special attention to the leakage of the fuel injector, which will cause the mixture to be thick when the car is hot, and it will not be able to ignite normally. If the injector is leaking. It's time to replace the injector.

Hello, where is the water temperature sensor.

The water temperature sensor is screwed on the cylinder block of your vehicle, a sensor with a wire. The head is inserted into the waterway of the cylinder head of the vehicle. Kiss.

Hello, this one is air-cooled.

The hot car of the air-cooled EFI vehicle is not good to catch fire, which is caused by the leakage of the EFI injector of the throttle, and the mixer is too thick.

The ignition is normal when the car is cool, because the mixer is thick, which is just enough to meet the start of the cool car, but when the car is hot, the mixture is thick, and it cannot be ignited normally. It won't be noticed.

Therefore, remove the fuel injector, that is, the throttle, and clean it if there is a leak, and after cleaning, it is still leaking, and it needs to be replaced.

Summary. The reasons why the EFI motorcycle cannot catch fire are: 1. The anti-theft system is locked; 2. The oil pump of the oil supply system is damaged; 3. Injector failure.

Exclusion method: 1. If there is no sound of oil pump running when opening the car key, check whether the fuse of the EFI system is blown and whether the oil pump relay is damaged, and replace the fuse or relay if necessary; 2. If there is a running sound, remove the injector, press the start button to see if the fuel injection condition is well atomized, and replace the injector if necessary. EFI motorcycle is a new type of motorcycle, which is to control the fuel injector to inject fuel to the cylinder that needs to work according to the load of the engine through the microcomputer, and the cylinder that does not work does not give oil.

Hello dear, I am happy to answer your <>

I have an EFI motorcycle that doesn't fire after changing the assembly line.

To check it out, there are many reasons.

What if it's an anti-theft system lock?

I can't read the fault even if I use the horse to solve the gas.

Are you there? In friends.

Hold on. There are three ways to solve the locking of the anti-theft system: 1. Repeat Sun Maodong three times to power on the vehicle, and then turn it off; 2. Disconnect the vehicle battery line for 15 seconds; 3. Wait for the engine fault light to appear on the dashboard, and wait for a few minutes before ignition.

If you can't deal with the anti-theft unlocking lock, you can only seek the help of the 4S shop, drag the vehicle to the 4 store by towing the car, and then check the specific anti-theft locking reason, and solve the anti-theft unlocking according to the relevant reasons and failures, which is the safest way.

What is the reason why you turn off the power and turn on the power of my car two or three times and then use a section of fire?

This situation should be that the vehicle has been discharged for too long, causing the battery to be discharged slowly and the battery is discharged. Then the vehicle started and drove for a while, and then suddenly turned off and was in a mess. This may be due to the relatively low amount of electricity dissipated by the battery.

It is recommended to take the battery to the garage for charging first. Then go and get the vehicle moving.

I see that the battery is enough.

That's still going to have to be checked.

You've been using the battery for a few years.
