How to start a motorcycle in winter

1. Some factors that are unfavorable to engine starting and running due to cold, rainy and snowy weather in winter: 1. When the weather is cold, the air contraction density becomes larger, which leads to insufficient fuel supply for the carburetor adjusted in summer. It needs to be readjusted and more fuel should be added to meet the ignition concentration. When the weather is cold, gasoline volatilizes slowly. Even if the enrichment on the carburetor is turned on, the fuel flowing into the cylinder will flood the spark plug, and the oil concentration in the combustion steam may not be enough. 3. The cold winter rain and snow weather has a great influence on the electronic ignition system of the engine, and it will be difficult to dry if it gets wet for a while, which is very unfavorable for starting. 4. In cold weather, the starting voltage of electronic components becomes larger, and some igniters that can be started normally in summer may not ignite at this time, and the spark plug also needs higher flashover voltage. Ordinary batteries can't be discharged in a cold environment. Even if they are fully charged the night before, people who are used to starting with electricity are often confused at this time. 6. Conventional lubricating oil is viscous in cold environment, and it has great damping in cold state in cold morning. Even if the ignition is on, it may not be possible to continue idling. 7. Most belts of four-stroke scooters are connected with the engine. In the cold state in the morning, the belt is particularly stiff, which has a great damping effect on engine starting. 8. At present, the enrichment device on the general carburetor can only give more fuel when the cold car starts, and there is no special atomization structure, which has limited effect on the cold car starting. 9. The locomotive is too cold in winter, the engine and belt have not been heated in place, and the electric thickening (electronic damper) has been closed. It is difficult to start again when you stop at this time. 10. In the cold outdoor environment, the infiltration of rain and snow will cause the engine, carburetor and muffler-water inlet failure, and the throttle pipe, brake pipe and belt-will be frozen. Second, the starting operation method for the above unfavorable factors is 1. Every time the weather is cold, finish the seasonal adjustment of the carburetor in advance, raise the main oil needle by one grid, thicken the idle oil for half a turn, and adjust the throttle in advance. 2. First, step on the starting lever a few times with your feet and coat the lubricating oil on the cylinder wall, which can improve the sealing performance of the piston and the temperature in the ignition cylinder. 3. In cold winter and rainy and snowy days, special attention should be paid to the protection of the engine electronic ignition system, and the place where it can be bandaged should be bandaged as much as possible to prevent rainwater from infiltrating. 4. Improve the starting speed of the pedal, change a charging coil with more turns when necessary, keep the spark plug clean and reduce the flashover gap of the spark plug electrode. 5. Try to put the car indoors and use the charging plug of AC power supply if possible; The practice of starting only by electricity is too uncertain, so you must learn to start with your feet. 6. In cold winter, change to thinner lubricating oil. Before starting the cooler, step on the pedal lever several times with your feet to make the lubricating oil stir. 7. The belt stiffness of the cooler is difficult to solve, so it will be better to put the car indoors; If thickening is not enough to maintain idle speed, we have to hold the throttle by hand to warm the car. 8. Traditional locomotives start the lever by stepping on the pedal until the engine can be started by friction and heat. Adding vortex storage containers can promote the vaporization of fuel. 9. The holes for adding concentrated oil are often blocked and ineffective. For an isobaric vacuum membrane carburetor with an acceleration pump, it is also helpful to start the carburetor by quickly turning the throttle to accelerate the oil discharge. 10. In the freezing rain and snow environment, waterproof measures should be strengthened for the engine, carburetor and muffler, and the valve pipeline and brake pipeline should be lubricated frequently. 3. Some suggestions on starting and using cold cars in particularly cold winter environment: 1. Never pour with hot water: when the parts are cold, pouring with hot water is equivalent to the destructive effect of pouring cold water with a heat engine, not to mention the possibility of freezing and leakage. 2. Try to put the locomotive indoors: even if it is not easy to start; Let the temperature of the engine not be too low when starting, that is, the anti-wear maintenance of the engine. If possible, you can add a charging socket to the locomotive. When the vehicle stays downstairs for the night, there is a micro power supply to charge and alarm, and it can be started by electricity the next morning. 4. If there are no conditions, more efforts should be made. Exercise the engine with the pedal rod for hundreds of times, and the engine cylinder will start naturally if it is not cold. If possible, you can connect a hair dryer downstairs to blow hot air into the air inlet of the engine when it is started. Under the action of hot air, the engine will be easier to start. 6. It is best to change the "electronic damper" on the carburetor to manual if you have DIY ability, and you can decide the switch according to the situation at that time to avoid the pain of not starting. 7. There is a secondary atomizing storage container specially used for cold start. If you can't do DIY, you can directly spray gasoline at the air inlet of the air cleaner with a pocket perfume bottle. 8. Another way is to add an air compression capsule to press the fuel in the carburetor onto the air-filtered foam plastic, which has a super thickening effect. 9. It is common that it is difficult to restart after shutdown due to the lag of the electrothermal thickening switch. If you don't have the patience to wait for it to recover slowly and naturally, try accelerating the oil pump. 10. In the cold rainy and snowy days, try the throttle line and brake line before starting, and be sure not to be short of water and oil, otherwise the pipeline will be frozen by rain and cannot stop.
