1. Reasons for the high fuel consumption of scooters
After a motorcycle is used for a period of time, the fuel consumption rate will increase and the power will decrease. Problematic performance. For riders who have a little basic knowledge of motorcycles, they can find out the problem of rising fuel consumption through several simple self-checking methods.
1. During the trip, it is found that the sliding distance of the car is significantly reduced, the sliding effect of the downhill road is weakened, and the empty car is more laborious than before. At this time, the owner of the car should check whether the tire pressure is up to standard. If the tires are under-inflated, the fuel consumption will increase a lot.
2. If the front or rear wheels are found to swing on the road, you should immediately check the air pressure and wear of the tires, and whether the wheels and cantilevers are loose. If the tires are badly worn or underinflated, they will often wobble, especially if the road has longitudinal grooves.
3. If abnormal noise is found on the axle during driving or when starting, check the bearing and braking system for faults in time. If the wheels turn abnormally, the brake pads = the rim heats up, which will affect the speed and stability of the vehicle and increase the fuel consumption.
4. The slippage of the clutch block of the scooter will affect the maximum speed and the moment of going uphill, and will also cause the nearby components to overheat. When it is found that the engine speed increases rapidly, but the vehicle speed increases very slowly, it can be determined that the clutch is slipping.
5. When the scooter travels for 20,000 kilometers, usually the piston ring will wear and leak, and the cylinder pressure will be insufficient. Cold start feels easier, but it is not easy to ignite successfully. The tightness of the cylinder is not good, and the fuel consumption will increase significantly.
6. The starting feeling is relatively easy, but the cold engine is not easy to start, the engine is not very powerful after starting, and the fuel consumption rate is high. For a four-stroke engine, it is a common thing that the valve is not closed tightly, which affects the starting and work, and it can be adjusted.
7. When the exhaust pipe often emits black smoke, the fuel consumption increases, and the spark plug has serious carbon deposition, it is necessary to check the air filter and adjust the carburetor. If the carburetor cannot be disassembled and cleaned, you can spray the cleaning agent directly to the air inlet of the carburetor several times when the machine is idling. The foam core of the air filter is easy to be blocked by dust, and it has to be disassembled and cleaned within six months at most; if the paper core cannot be washed, replace it. After cleaning the air filter and carburetor, if there is no effect, it may be that the oil level is too high, and the carburetor must be disassembled for cleaning and adjustment.
8. The scooter is difficult to start, and the fuel consumption rate is always high; it is necessary to check the electric heating enrichment valve on the carburetor. Check if it gets hot after booting up! If it doesn’t heat up, it’s usually because the wiring is broken and no electricity = the enrichment has been on. There are also some cars with plunger carburetors, which are usually adjusted to be very rich in order to accelerate quickly and powerfully.
9. If the vacuum membrane carburetor on the scooter is used to a certain extent, its starting oil outlet will be blocked, which will affect the starting. That section of the oil circuit is a dead end. Even if it is disassembled, it is difficult for ordinary people to clean it in place. It is the dead hole in the structure of this carburetor. The usual practice is to increase the main oil and idle oil, and use the high and low speed ends to be rich in oil to drive the vehicle to drag through this oil-poor area. This has a bit of an effect and is common on many scooters; it’s just that the fuel consumption rate of the whole vehicle is not very low. The complete solution is to use a plunger carburetor, but many rookies’ refueling methods have been ruined and cannot be used to.
10. It is difficult to start overnight, and the vehicle body smells of gasoline; should check the carburetor and fuel system for slight oil leakage? Some carburetor bottom casings are not tightened tightly, or the oil pipes are cracked. This kind of chronic oil leakage will waste a lot of oil unconsciously. The most hateful thing is that there are some tiny cracks, and the oil leaks only when the driving is bumpy, and the gasoline volatilizes on the spot when it is heated, which is very dangerous!
11. When the fuel consumption rate of the scooter is getting higher and higher, it is necessary to check whether the belt, pulley and pulley are worn out? Especially those that feel that the engine is more laborious, the fuel consumption rate is relatively high, and the speed of the vehicle is not high, which is usually related to the wear of the belt pulley. When the loose pulley is running, there is a kind of “entrainment” phenomenon on the belt; this kind of clenching of the belt will double the fuel consumption.
12. After the spark plug is used for one year, the electrode is ablated by the electric spark = the electrode flashover gap is too large, and it is not easy to ignite when starting. There is also improper adjustment of the carburetor, long-term rich oil will lead to carbon deposition on the spark plug, and it is not easy to catch fire when the cold engine is started. Maintenance method: Remove the spark plug, manually scrape off the carbon deposits, adjust the electrode gap, and test the ignition energy to a few millimeters.
Second, small ways to save fuel for scooters
1. What types of “scooters” are we often talking about?
I have a scooter with a displacement of 125. Many of my friends ride Wu~yang~ben~tian, which has a displacement of 100. Scooters with other displacements are rare, mainly 125 and 100.
2. Buy a motorcycle with good engine performance
There is no doubt that a scooter with good engine performance (such as EFI type) is very good. Fuel-efficient, although the price is more expensive, but in the long run, it is still very cost-effective. Some low-quality scooters, or mopeds are cheap, but they are the “ancestors” of drinking oil.
3. Pay attention to daily maintenance (change oil, air filter frequently)
According to some friends who are engaged in motorcycle maintenance, the daily life of scooters In maintenance, it is very important to change the oil and air filter frequently. The oil should be changed every 1,500 kilometers (good quality engine oil), and the air filter should be changed every 2,000 kilometers. Also, remember to check your tires for flat air, and remember to refill your tires frequently.
4. Choose high-quality tires
Tires with better wear resistance are a good choice, and the scooter chassis is low and the tires are very durable. The essential. When choosing tires, look at the brand and quality, and it is recommended to follow the recommendation of the maintenance master.
5. Pay attention to speed and strength when driving a scooter
That is to say, do not stop and accelerate frequently when riding, and keep a Relatively stable speed is very important. It is recommended that you set the speed between 40-60 yards. In addition, pay attention to the grasp of the degree of attention when the accelerator is on, and do not slam it too hard, it will hurt the engine.
6. Try not to run long distances and roads with poor road conditions as much as possible
If you want to run long distances (more than 50 kilometers), try not to use scooters , that is very fuel-intensive, because the road is too long, the engine is prone to overheating, resulting in increased fuel consumption. In addition, unless it is a road with better hardening conditions, it is best not to run on other gravel roads, potholes and dirt roads with poor road conditions. On the one hand, it is uncomfortable for people to ride. Increased fuel volume (inadequate combustion of gasoline).
