How to Determine if a Vehicle Meets China 5 Emission Standards

What are the reasons for the Buick Verano not responding when starting?

Buick Verano not responding when starting may be due to reasons such as incorrect engine timing or control module failure. Below are the specific explanations: 1. Prolonged vehicle parking: The usage time of the car battery is the main cause of power loss. Typically, the lifespan of a car battery is two to three years. If it exceeds this period, the car is highly likely to experience power loss after being parked for two to three days, leading to weak starting. 2. Forgetting to turn off lights and onboard electronics: If the interior lights are left on when parking and turning off the engine, the battery may be depleted after a night, resulting in insufficient power and weak starting. 3. Forgetting to turn off the air conditioning before shutting down the engine: Most drivers are accustomed to leaving the air conditioning on or letting it start automatically when the vehicle is turned on. This causes the air conditioning system to activate automatically every time the ignition switch is turned on, directly leading to an instant high power load on the vehicle. Over time, this will cause wear and tear on the battery.

Will a Burned-Out Front Oxygen Sensor Cause No Idle Speed in the Buick GL8?

Buick GL8 front oxygen sensor burned out will cause no idle speed, the following is a detailed introduction: 1. Oxygen sensor damage: After the oxygen sensor is damaged, it will affect the engine's acceleration weakness, insufficient power, and increased fuel consumption. 2. Front oxygen sensor: The oxygen sensor includes the front oxygen sensor and the rear oxygen sensor. The front oxygen sensor mainly checks the oxygen content in the exhaust gas after combustion. If the detected oxygen content is high, it means more air and less fuel, i.e., the mixture is lean. Less fuel means less oxygen is consumed during combustion; therefore, the oxygen content in the exhaust gas will be higher. In this case, it sends a signal to the engine computer, which then adjusts the fuel injector to reduce the fuel injection volume. Conversely, if the oxygen sensor detects low oxygen content, it means more fuel. The engine computer will then reduce the fuel injection. This way, fuel consumption, power, and engine working conditions can be adjusted to the best state. 3. Rear oxygen sensor: It is installed behind the three-way catalytic converter. It provides the engine computer with the composition data of the exhaust gas after being filtered by the three-way catalytic converter. The engine computer then uses the data from both the front and rear oxygen sensors to check the working efficiency of the three-way catalytic converter.

What oil is needed for lubricating the three-piece unit?

For the pneumatic three-piece lubricator, use JIS-K2213 transmission oil (ISO-Vg32 or equivalent). Below is relevant information about the pneumatic three-piece unit: 1. Introduction: In pneumatic technology, the combination of an air filter, pressure reducing valve, and lubricator into one unit is called a pneumatic three-piece unit. It is used to purify and filter the air source entering pneumatic instruments and reduce the pressure to the rated supply pressure for the instruments, functioning similarly to a power transformer in an electrical circuit. 2. Features: The pressure reducing valve stabilizes the air source, keeping it in a constant state, which reduces damage to valves or actuators caused by sudden changes in air pressure. The filter cleans the air source by removing moisture from the compressed air, preventing moisture from entering the device with the gas. The lubricator lubricates moving parts of the mechanism, including components that are difficult to lubricate, significantly extending the service life of the mechanism.

What is the fuel tank capacity of the Vizi V2 in liters?

The fuel tank capacity of the Vizi V2 is 37 liters, as officially announced. The Vizi V2 requires 92-octane fuel, with a fuel consumption of 6.1L per 100 kilometers. A full tank can cover a distance of approximately 606km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In practice, the actual amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This extra space is designed to accommodate fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount added may exceed the marked capacity.

Is Rusty Brake Pads a Sign of a New Car?

It is normal for new car brake pads to have rust, and rust on the vehicle's brake discs is a common phenomenon that does not affect the normal use of the car. Moreover, it is not a standard for checking whether a vehicle is new. However, car owners should regularly inspect the condition of the brake pads and replace them in a timely manner. Below are some considerations when purchasing brake pads: 1. Four Key Points to Check: (1) Check the friction coefficient. The friction coefficient determines the basic braking torque of the brake pads. If it is too high, it can cause wheel lock-up during braking, loss of directional control, and overheating of the pads. If it is too low, the braking distance may be excessively long. (2) Check safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. Under high temperatures, the friction coefficient of the pads may decrease. (3) Check comfort, including braking feel, noise, dust, smoke, and odors, which are direct reflections of friction performance. (4) Check lifespan. Typically, brake pads can ensure a service life of 30,000 kilometers. 2. Two Choices: (1) Choose automotive brake pads produced by reputable manufacturers, with license numbers, specified friction coefficients, and compliance with standards. The packaging should include a certificate of conformity, production batch number, and production date. (2) Choose to have them installed by professionals at specialized repair shops.

Does a Malfunctioning Traffic Light Count as Running a Red Light?

Running a red light due to a malfunctioning traffic signal does not count as a violation. If the violation was indeed caused by objective reasons such as a traffic light failure, you can file an appeal for reconsideration. Criteria for determining running a red light: Electronic surveillance cameras capture three photos as evidence for running a red light: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered running a red light. How to avoid running a red light while driving: Follow the arrow signal if available; otherwise, observe the circular light. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light starts flashing, if you are close and moving fast, you should proceed, as stopping might be difficult and could result in crossing the stop line. If you are far away, moving slowly, or the intersection is congested, you should stop. When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection.
