why High fuel consumption

- Apr 09, 2018-

The level of fuel consumption is an important performance indicator that motorcycle users are most concerned about. It is also an important performance indicator for motorcycles. The carburetor is a key component of the motorcycle fuel supply system. Whether the carburetor is in good condition or not is critical to the fuel consumption of the vehicle. Reducing fuel consumption is also a constant pursuit of carburetor manufacturers.

How to judge the high fuel consumption of motorcycles? The general actual fuel consumption law is: two strokes are higher than four strokes, large displacements are higher than small displacements, and automatic clutching is higher than manual clutching. In addition, the structure of the engine is different, and the level of fuel consumption is also different. The specific value should be based on the specific model. For the current domestic models, two-stroke 50 vehicle fuel consumption is about 3l/100km, four-stroke 70 to 100 vehicle fuel consumption is less than 2l/100km, four-stroke 125 vehicle fuel consumption is about 2l/100km, and four-stroke 70 to 125. Scooter fuel consumption is about 3.0l/100km. Based on this, the user can roughly determine whether his car has high fuel consumption.

Reasons for high fuel consumption and how to eliminate it:

1: carburetor leak

The causes of oil leakage and how to eliminate it are listed before.

2: The air volume of the oil is partially blocked

Cause: Partial plugging of the oil air holes in the oil system will cause the carburetor fuel supply to be concentrated, resulting in increased fuel consumption.

Exclusion method: According to the above carburetor cleaning method can be cleaned.

3: Poor startup and enrichment device shut down

The reasons for the lack of start-up and enrichment device shutdown and exclusion methods see before.

4: The main oil needle has a reduced wear outer diameter, and the main nozzle hole is worn through

Cause: The above components wear out due to long-term high-speed erosion of impurities contained in gasoline during use, which causes the main oil needle diameter to decrease and the main nozzle hole to increase, resulting in increased oil supply and increased oil consumption.
