Why are scooters more and more fuel guzzling?

The gliding performance of a gear car is much higher than that of a scooter.

Due to the belt drive of the scooter and due to the characteristics of the drive train, even when going downhill, due to the anti-drag effect of the engine, it is not easy to slide without oil. The gear car can be forced to use a more fuel-efficient gear ratio under the control of the gear, but the scooter engine is a continuously variable gear, and a relatively low gear ratio will be automatically adopted when the power is insufficient, and due to the slippage of the belt and the pulley, it will cause a loss of power, so the scooter is more fuel-efficient.

Are you satisfied with the above?

Why are scooters more and more fuel guzzling? The real reason is simple! All motorcycles consume more and more fuel during riding, but the scooter consumes more fuel, and the copycat scooter drinks fuel directly. The reasons for this are none other than the following points:

The scooter fuel consumption is getting higher and higher, and the first thing to check is the air filter system. Theoretically, the air filter should be cleaned or replaced every 3,000 km. Since many scooter users do not know how to maintain the vehicle, it is impossible to replace the air filter.

Air filtration not only has an impact on fuel consumption, but also on strength, engine durability, etc.

2.Scooter clutch flicker failure. For scooters, the clutch flicker is also a wearing part, and the damage of the copycat scooter will be aggravated. The pedal drive is all dependent on the clutch flicker, and the clutch flicker is damaged at low speed, which affects the power and then increases fuel consumption.

3.Carburetor aging. Due to the average quality of the carburetor of the cheap scooter itself, coupled with the quality of gasoline and other reasons, the aging and damage of the carburetor is accelerated. The damage of the carburetor directly causes insufficient combustion of gasoline and increases fuel consumption.

4.Sleeve cylinder combination problem. The reciprocating motion of the piston ring, piston and cylinder block will inevitably lead to wear. The combination of inferior sleeves and cylinders will wear out faster. After the sleeve cylinder combination is worn, it is possible that the oil and gasoline will be diverted to each other, which will increase the amount of gasoline loss.

5.Other reasons. Such as tire pressure reasons, spark plug reasons and so on.

3.The engine itself has insufficient combustion, which is generally caused by the air filter not being cleaned in time.

4.Carburetors, scooters because of the particularity of the air filter, the carburetor also needs to be cleaned frequently, the focus should be on checking the electronic damper, which will also affect fuel consumption.

5.If the engine valve clearance is too large, the valve clearance of the engine needs to be adjusted, and if it is too large, it will affect the air change time and volume of the engine.

6.The engine has an oil failure, scooters, especially small displacements, are prone to oil failure, once the vehicle burns oil, then the fuel consumption will rise rapidly, and the engine must be repaired.

The main factors for the high fuel consumption of the scooter itself are as follows:

1. Although the belt stepless speed change is easy to use, the belt drive consumes more energy; Even if it is in a hot state, there is generally a two-percent transmission consumption, and the equivalent of running is almost less than three-percent of the road yards. In the case of cold driving, the belt damping is greater, consuming almost 40% of the engine's output. There is also the "entrainment damping" after the wear of the belt pulley, which usually causes nearly half of the engine's energy to be consumed on the belt drive system; In other words, almost 30% of the scooter fuel is consumed on the belt drive system, otherwise the same amount of fuel can run an additional 40 miles.

2. The belt stepless speed change is based on the engine speed to change the transmission ratio, rather than the manual selection of the transmission ratio according to the driving speed and load like the gear car, and the economic transmission situation of high speed and low speed can not be achieved. This "shifting" makes it difficult for the engine to be optimally fuel-efficient, and as a result, the scooter's fuel consumption rate remains high, often only reaching the 65 of the Curved Beam with the same amount of fuel.

3. Although the isobaric vacuum membrane carburetor can theoretically prevent the negative pressure of the throat from being too low and lean oil caused by the newcomer suddenly tightening the throttle, this kind of carburetor itself is a more complex and oil-consuming and easy-to-fail imitation model. In the oil circuit structure of this type of carburetor, only the idle speed saving and idle oil concentration are usually arranged, and the main oil needle is generally not adjustable; In other words, the main oil system is preset in a very oil-rich state, which is enough to adapt to the ambient temperature of the north and south and the four seasons of summer and winter.

How can such a design not be rich in oil? How can you call a scooter without consuming fuel?

4. Although the shell of the scooter is more streamlined, the tires used in most domestic scooters are relatively thick and short, and the wheels of some cars are almost similar to pumpkins; Compared with the tires of the curved beam car, its off-road ability is much worse, and the driving resistance is also relatively large.

The enrichment of the scooter carburetor is an electronic enrichment, in normal work there will always be wear and tear on the needle valve inside it, which eventually leads to the problem that the enrichment channel is not closed tightly, this process is very slow, when the fuel consumption is too high, I recommend changing the carburetor directly.

The second-hand 125 has been replaced, and the average is about one kilometer of cents, and now the oil price is so expensive, which is normal. Imported "Black Sand" 125, now it is almost 3-4 cents per kilometer. If you want to save, you can only change to an electric car.

The scooter comes to be very fuel guzzling, but the engine of 80 (if the source is really this bai displacement) 5 oil du is too high. The reasons for the excessive fuel consumption of the scooter are blocked air filter, the carburetor mixture is too thick or the oil level of the float chamber is too high, the electronically controlled concentration valve (electric damper) cannot be closed when the car is hot, the vacuum fuel tank switch is not good and cannot be closed after the ignition is turned off or the oil intake cylinder (through the intake pipe) flows from the suction pipe, the belt and pulley slip, the brake is too tight or the tire pressure is too low, the valve is leaking, the intake and exhaust is insufficient, and the gasoline tank is leaking. In addition, it is necessary to pay attention to driving at an economic speed of 40 to 50 km/h, and not to accelerate and brake sharply, etc., which will help to reduce fuel consumption.

In addition to what you said about changing the oil and cleaning the air filter, there is.

Check the tire pressure frequently, check whether the tire pressure is normal, the tire pressure is too low, and the fuel consumption will also be changed, and the oil filter should also be changed, and the oil nozzle should be cleaned when maintenance! Pay attention to driving habits, always a big throttle must be a waste of fuel! In addition, whether the run-in of the new car is good or not will also affect the fuel consumption of the car in the future!!

Check the piston rings and cylinder block head;

Whether there are signs of oil leakage in the aging of the tubing;

carbon deposition in spark plugs;

Wash the carburetor, especially the nozzle and thimble;

Whether the output current of the high-voltage package is strong enough;

Rolling smoothness when the front and rear wheels are pushed (the wheels also consume fuel if they don't turn well).

Let's look at these six aspects first.

The reason why scooter bai consumes a lot of fuel:

Scooters du motorcycles.

ZHI air filter and carburetor blockage; Transmission DAO

The belt and pulley are slippery back; excessive wear of the camshaft and swingarm of the air answering valve; The inlet pipe is leaking, the spark plug electrode has carbon deposit, and the gap is incorrect; Reasons such as low fuel marking often cause scooters to consume too much fuel.

Tip: Go to a professional motorcycle repair shop for a careful inspection and replace parts that are overworn, so as to reduce fuel consumption.

Obviously, the fuel consumption of this car is too high, according to 7 yuan liters, 40 7 liters 100 kilometers. Now the fuel consumption during the run-in period is more, but even if the fuel consumption is out of the run-in period, it is also high. The following modifications can be made:

Change the carburetor, change the 18g pulley beads, change the soft and large springs, change the switch rectifier, and change the iridium spark plug. After the change, there is no problem with the fuel consumption being reduced to the limit.

Clean the carburetor and change the oil on time.

Sell and buy a bicycle.

There are many reasons why a copy scooter consumes a lot of gas. You can go to the place where the car is repaired and let them inspect it, focusing on the carburetor and the oil pipe. The engine oil should be changed regularly, otherwise it will also affect the fuel consumption. The quality of the new car run-in may also cause an increase in fuel consumption.

Pedal 125 general nominal fuel consumption is; This one is standard. But if you want to consider whether you are riding in the city or riding long distances, fuel consumption will fluctuate, but it will not be so bad. I don't know if you are a WhatsMiner model, the Carburetor and the air filter are also the key to a good match.

Generally, with 125 pedals and 4 liters, there is no problem in riding 100km.

Pedal bikes do have slightly larger fuel consumption than straddle bikes and curved beam bikes, which is mainly related to the way the pedal bikes transmit power.

Reason: The clutch does not combine when the engine is idling, increase the throttle when starting, the speed rises, and the clutch thrower overcomes the spring force under the action of centrifugal force to combine and transmit power to the wheels. Since it takes a lot of power to start, the clutch needs to rev higher to ensure that the centrifugal force is large enough to provide enough friction.

Because of the unique transmission and engine structure of the scooter, the straddle bike will definitely cost more fuel than the displacement model. If the fuel consumption level of the scooter is higher than that of other vehicles, this performance is abnormal due to the following reasons: The tire pressure is too low:

If the tire pressure is too low, it will increase the driving resistance of the vehicle, and if the driving resistance of the vehicle is large, the fuel consumption performance will definitely increase. The brake clearance is too small: the brake clearance of the scooter is too small, which will cause the phenomenon of braking on the way, and the phenomenon of braking will also increase driving resistance.

Unreasonable driving habits: The driving habits of riders will directly affect the fuel consumption gauge of the vehicle, because the best fuel consumption performance of the vehicle is based on reasonable operation, and only then will the fuel consumption performance of the vehicle be more optimistic. Yamaha's fuel consumption for the 2021 XMAX250 motorcycle is generally within the range specified in the manual.

Due to improper use, maintenance or adjustment, the fuel consumption often increases exponentially. Here's an extended look at fuel consumption: Ignition too late or too early:

The ignition time is too early, the mixture burns ahead of time, the piston is resisted upward, and part of the effective heat energy is consumed, which leads to a decrease in engine power and an increase in fuel consumption. Fuel labeling is too low: When using gasoline with a low octane number, fuel consumption is likely to increase.

Generally speaking, gasoline with a high octane number has good combustion performance. Therefore, the fuel number should be specified in the instructions and the fuel should be selected correctly.

The high fuel consumption of a motorcycle can be caused by too high idle speed, or it can be caused by low tire pressure causing the tire to rub against the ground too much. If fuel consumption rises, be sure to check the idle speed and tire pressure. If the idle speed is too high, it should be adjusted immediately.

Tires are an important part of motorcycles and automobiles because this part is the only one that touches the ground.

Tires are critical to maneuverability, driving stability and safety.

If the tire pressure is too low, the contact area between the tire and the ground will increase.

The larger contact area between the tire and the ground leads to greater drag when driving, which naturally leads to higher fuel consumption.

The air pressure of the tires should not be too high. If the air pressure is too high, the contact area between the tire and the ground will be smaller, resulting in poor grip.

If the grip is worse, the car's handling and driving stability will also be worse.

Therefore, it is recommended that you always check the tire pressure when using your car.

If the air pressure is not suitable, it needs to be adjusted immediately.

Moreover, tires belong to rubber products, and rubber products need to be replaced regularly, because rubber products will age after long-term use.

Therefore, it is recommended that you change your tires regularly when you usually use the car.

When buying new tires, be sure to look at the production date because tires also have a shelf life.
