What happens when a motorcycle oxygen sensor fails?

When the oxygen sensor of a motorcycle fails, due to the working environment often being in a state of excessive carbon content, aging and poisoning phenomena will occur. Aging refers to the reduction in working efficiency caused by high temperatures that the sensor cannot withstand, while poisoning occurs when the oxygen sensor fails due to excessive accumulation of carbon monoxide, resulting in a poisoning failure. In addition, if the internal resistance wire burns out or the sensing wire falls off, it can also cause the front oxygen sensor to fail. If the vehicle experiences reduced power, difficulty in acceleration, unstable idle speed during operation, increased fuel consumption, and excessive emission of pollutants, these may all be signs of a faulty front oxygen sensor. Of course, it is also necessary to first check the car's engine and whether it is a spark plug failure or a fuel supply device failure. Additional Information: 1. Low-end motorcycles do not have oxygen sensors; only some motorcycles equipped with electronic fuel injection engines will have oxygen sensors. The oxygen sensor is installed in front of and behind the three-way catalytic converter. The oxygen sensor in front is called the front oxygen sensor, and the one behind is called the rear oxygen sensor. The main function of the front oxygen sensor is to detect the oxygen content in the exhaust, and then the ECU can adjust the air-fuel ratio based on the data transmitted by the front oxygen sensor. The main function of the rear oxygen sensor is to check whether the three-way catalytic converter has failed. 2. If the data transmitted by the front and rear oxygen sensors to the ECU are similar, it indicates that the three-way catalytic converter has failed. If the three-way catalytic converter fails, the fault light on the dashboard will illuminate to alert the driver. It is normal for the three-way catalytic converter to fail after prolonged use. If low-quality gasoline is frequently used, it can reduce the service life of the three-way catalytic converter. Therefore, it is recommended that owners choose gas stations with relatively better fuel quality when refueling.

What does the 'eco' on the car screen mean?

When the eco indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode has been activated. 'Eco' is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active eco driving mode and non-active eco driving mode. When the eco indicator light on the dashboard illuminates, it signifies that the vehicle's economy mode is engaged. Eco mode is categorized into active and non-active types, with the difference being that the active type has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active eco mode does not have a dedicated button. When the dashboard eco indicator light illuminates, it serves merely as a reminder function. The eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most vehicles employ the active eco driving mode, meaning they have a separate switch button. Therefore, during daily driving, we can generally enable eco mode. However, it is unnecessary to activate eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of eco mode but also impair the vehicle's power performance. Additionally, eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will not function in such scenarios.

Should I Shift to N or D Gear When Using Autohold?

When using autohold, simply keep the gear in D. Below are specific details about autohold automatic parking: 1. Autohold is an electronic parking brake, not a mechanical handbrake. Once the vehicle comes to a stop, the autohold light will turn on, and you can release the brake pedal. 2. There is no need to shift to N gear. When autohold is activated, it is equivalent to shifting to N gear and pulling the handbrake. The car will only idle and will not cause any damage. 3. After enabling this function, when stopping at a red light, pressing the brake pedal firmly will automatically engage the parking state, eliminating the hassle of pulling the handbrake. 4. This function is particularly useful on slopes and during frequent stops and starts, preventing the car from rolling easily.

What does ODO mean on a car?

ODO on a car represents the vehicle's total mileage. ODO is the abbreviation of the English word "odograph" (representing total mileage, automatic odometer). In contrast, TRIP in English means short-distance mileage, also known as the trip mileage, which is convenient for users to calculate the kilometers traveled for each trip, i.e., the distance recorded after manually resetting the odometer. The introduction to the odometer is as follows: 1. Traditional speedometers are mechanical. A typical mechanical odometer is connected to a flexible shaft, which contains a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer's housing to rotate. The housing is connected to the pointer and, through a hairspring, keeps the pointer at zero. The speed of the magnet's rotation causes changes in the magnetic field strength, disrupting the balance and thus moving the pointer. 2. This type of speedometer is simple and practical and is widely used in both large and small vehicles. Most modern cars use electronic sensor speedometers without flexible shafts. A common type obtains signals from a speed sensor on the transmission, using changes in pulse frequency to deflect the pointer or display digital numbers indicating the car's speed. 3. The car odometer also includes two LCD digital display windows connected to the same signal source, which respectively display the trip mileage and the total mileage. The trip mileage usually has four digits for short-term counting and can be reset; the total mileage has six digits and cannot be reset. The accumulated mileage numbers in an electronic odometer are stored in non-volatile memory, allowing the data to be preserved even without power.

Why can't the foot brake of Geely Emgrand be pressed down?

This situation is due to the need to replace the brake fluid or a malfunction in the vacuum booster. The function of the vacuum booster: The vacuum booster utilizes the pressure difference between the vacuum generated by the vacuum pump and atmospheric pressure to multiply the braking effect, making it easier to press the brake pedal and ensuring safe and rapid braking. When the vacuum booster malfunctions, it cannot provide the boosting effect, but the hydraulic brake system can still ensure driving safety. The working principle of the vacuum booster: When the brake pedal is pressed, the control force from the pedal mechanism pushes the control valve push rod and the control valve plunger forward. After eliminating the gap between the plunger and the rubber reaction disc, it continues to push the master cylinder push rod, causing the brake fluid in the master cylinder to flow into the wheel cylinders at a certain pressure.
