What to Do If the Vehicle Fails the Exhaust Emission Test?

The solutions for a vehicle failing the exhaust emission test are: 1. Perform a three-way catalytic converter cleaning maintenance on the engine, cleaning the three-way catalytic converter and oxygen sensor; 2. Replace the spark plugs, clean the distributor contacts and distributor rotor contacts, and adjust the ignition timing; 3. Clean the air filter, and replace it if it is too dirty; 4. Switch to 97-octane gasoline or 97-octane ethanol gasoline and take a high-speed drive; 5. Near the testing station, use a high-pressure pump at a car wash to add some water into the exhaust pipe, insert a filter screen into the muffler, or use a vehicle exhaust purifier by adding it to the fuel tank and idling for 20 minutes or driving 5 to 10 kilometers.

What does ECO mean on a car?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active eco driving mode and passive eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode has been activated. ECO mode is categorized into active and passive types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to activate 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. The passive ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder. The ECO system automatically evaluates driving behavior, and if the current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars use the active ECO driving mode, which means they have a dedicated switch button. Therefore, during daily driving, the ECO mode can be activated. However, it is unnecessary to activate the 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, as it does not reflect the fuel-saving characteristics of the ECO mode. Additionally, the ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, and the ECO mode automatically deactivates. During idle parking or when in N/P gear or manual mode, the 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 cases.

What does it mean when a wrench symbol appears on the car?

When a wrench symbol appears on the car, it is a reminder that the vehicle requires maintenance. The small wrench indicator light on the combination instrument panel is a maintenance reminder light, designed to alert the owner to perform vehicle maintenance after a certain mileage has been driven. In other words, when this light stays on for an extended period, the owner should take the vehicle to a 4S dealership for maintenance. Different car models from various manufacturers have different maintenance intervals, so it's essential to refer to the vehicle's user manual. The appearance of the small wrench on the dashboard does not indicate a vehicle malfunction; it is merely a maintenance indicator. The maintenance cycle is preset when the vehicle leaves the factory, so the small wrench symbol will appear at regular mileage intervals to remind the driver to perform timely maintenance.

What is the pressure of automotive air conditioning refrigerant?

The pressure of automotive air conditioning refrigerant varies under different conditions: 1. When the compressor is running at 1500 to 2000 rpm, the high pressure is approximately 1.5 to 2.0 MPa, and the low pressure is around 0.15 to 0.35 MPa. 2. At idle speed, if the ambient temperature is high or under direct sunlight, the high pressure may be slightly higher, reaching about 2.5 to 2.8 MPa, but it generally does not exceed 3.1 MPa. Normally, cars do not need to add refrigerant for 3 to 5 years, but sometimes if the cooling effect is poor, it may be necessary to add refrigerant. After the air conditioning has been running normally for a while, the air blowing on you should feel cool and quickly reach the set temperature. The outdoor compressor should operate like a refrigerator, sometimes working and sometimes stopping, which indicates normal operation. Otherwise, it may need refrigerant.

What are the symptoms of a faulty vehicle high-voltage line?

The symptoms of a faulty vehicle high-voltage line are: 1. The spark released by the spark plug will appear dark yellow and lack sufficient energy, making it difficult to effectively ignite the air-fuel mixture; 2. The spark plug electrodes may fail to release sparks, preventing the air-fuel mixture from burning and resulting in engine misfire. Engine misfire leads to reduced power, increased fuel consumption, and noticeable vibration and noise. Prolonged fuel injection without ignition in the engine cylinder can also cause gasoline flooding. Symptoms of ignition coil failure: 1. At idle, the vehicle body shakes noticeably; 2. While driving, when the engine speed is below 2500 RPM, the vehicle body exhibits significant shaking and weak acceleration; the shaking sensation disappears once the speed exceeds 2500 RPM. 3. Upon opening the engine hood and observing the running engine, noticeable engine vibration can be detected.

What are the reasons for brake lights not working?

Reasons for brake lights not working: brake switch, brake light circuit, brake light bulb, circuit fuse failure. Solutions for brake lights not working: 1. Replace the bulb; 2. If the brake light switch is faulty, all brake lights will not work. During inspection, you can use a wire to connect the brake light switch. If the brake lights turn on, it indicates the switch is damaged and needs replacement; 3. If both the bulb and switch are confirmed to be working properly, check the fuse. Some cars do not have a separate brake light fuse and share one with other electrical devices. In this case, check the operation of other electrical devices in the car, identify the non-working ones, and replace the corresponding fuse.
