Yang Guangwan oxygen sensor failure.

Yang Guang Bender's couple's fuel consumption is about 2.2-3 liters per 100 kilometers.

In fact, most of the fuel consumption problems of motorcycles are caused by hidden dangers of vehicles.

1. Tire depression: If the tire working pressure is too low, the amount of subsidence will increase, the tread edge load will increase, the tire shoulder will wear prematurely, and the rolling resistance will increase, which is unfavorable for fuel saving and tire saving. Considering the safety and fuel economy, it is necessary to check the tire pressure regularly. Different types of motorcycles have different tire pressures. When driving alone or in pairs, the tire pressures required by the front and rear wheels are also different. However, it is generally impossible to adjust the tire pressure every time when driving alone or in pairs. Professionally, it can be judged according to the barometer and the tire pressure above the tire. Bian Xiao used a family motorcycle as an example. The front tire and rear tire of the straddle bent beam with a displacement of about 125 are about 2.25, 2.75, 2.00 and 2.50 respectively.

2. High viscosity of engine oil: The engine oil with high viscosity will increase the internal running resistance of the engine, and the flow speed of the engine oil will be slow, resulting in an increase in fuel consumption. Choosing the right viscosity engine oil can also effectively control fuel consumption.

3. Long-term non-replacement of air filter: If the air filter is not cleaned or replaced for a long time, it will seriously affect the air intake of the engine, resulting in insufficient engine power and increased fuel consumption. Car owners are advised to clean or replace the air filter on time.

4. The spark plug is in poor condition: after the spark plug is used for a long time, the carbon deposit increases and the spark plug gap increases, which may lead to poor ignition performance, decreased engine power and increased fuel consumption.

5. Oxygen sensor failure: When the oxygen sensor fails, the oil-gas mixture ratio will be affected, which not only leads to obvious oil consumption, but also may lead to the deepening of tail gas color, the emission is not up to standard, and the carbon deposition increases sharply during driving.

6. Engine products: As long as the carbon car runs, it will naturally produce carbon deposit, and it is still everywhere. The most fundamental solution is to give your car a comprehensive engine carbon cleaning regularly. However, there seems to be no professional place for cleaning carbon deposits in motorcycle engines. Even with this service, the price is quite expensive. It is suggested to add genuine maintenance or clean fuel additives to the automobile fuel tank regularly and appropriately to avoid riding at low speed for a long time and occasionally pulling up the speed, which can effectively reduce carbon deposition.
