Can Modified Exhaust Pipes Pass Vehicle Inspection?

Modified exhaust pipes can pass the vehicle inspection as long as they do not alter the vehicle's color, engine, or body. Here is some relevant information about vehicle inspection: 1. Conditions: Vehicles whose condition does not match the records in the driving license or vehicle registration, or whose license plates or driving licenses are damaged, incomplete, illegible, or self-made. 2. Precautions: The exterior of the vehicle must not be modified. The tint of sunshade or explosion-proof films on windows must not be too dark (items inside the vehicle must be clearly visible from one meter away; mainly applies to vans and trucks, but not to small cars with fewer than 5 seats). Vans and trucks must have enlarged rear license plates. The number of spring leaf plates must not be increased or decreased. The number of seats in vans must not be altered, and a fire extinguisher must be present. The cargo compartment of box trucks must not be modified (no side doors, no roof openings, no tailgate additions). The size of tires must not be changed, and the tread patterns of tires on the same axle must be consistent. Vehicles with unresolved traffic violations or those impounded by the court cannot undergo inspection.

How to Get a Toll Card for First-Time Highway Users

Henan Province is expected to fully implement the National VI emission standards for motor vehicles starting from July 1. Below is an introduction to the National VI standards: 1. Definition of National VI standards: The National VI standards, or the China VI emission standards for motor vehicles, are established to enforce environmental protection laws, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. 2. Implementation timeline of National VI standards: Currently, the National VI standards are divided into National VIa and National VIb, with plans to implement them nationwide in 2020 and 2023, respectively. The implementation of National VI standards will impose stricter requirements on emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons. The National VI standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine on December 23, 2016, and June 22, 2018, respectively. The "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)" came into effect on July 1, 2019. Based on past experience, vehicles meeting National II standards were phased out when National V was implemented, so it is highly likely that National III standard vehicles will also be phased out after the implementation of National VI. The timing of the phase-out will depend on the actual conditions of each region.

At what water level is a car considered flooded?

Flood-damaged vehicles refer to cars that have been submerged in water, typically indicating that the wiring harness has been soaked, the water immersion depth exceeds one-third of the wheel height, and the underbody components have been in prolonged contact with water. Impact of engine flooding: When the water level during wading is higher than the engine's air intake, water can directly enter the cylinders, forming a mixture of air and water. While air is compressible, water is not. This means that when the crankshaft pushes the connecting rod to compress toward the piston, the water cannot be compressed, causing the connecting rod to bend under the resistance of the water. If the owner attempts to restart the vehicle after the engine has stalled due to water ingestion, the immense counterforce can cause the bent connecting rod to rub against the cylinder wall, potentially rupturing the engine block instantly, resulting in exorbitant repair costs. Impact on interior: When water rises above the door level, the car's interior is likely to get flooded. Rainwater is not clean and contains many impurities. Post-flood, the car interior becomes an extremely humid greenhouse environment—ideal for mold growth. If the vehicle is not dried promptly, mold can quickly ruin the interior's fabric and leather upholstery.

What are the body dimensions of the Range Rover Evoque?

The length, width, and height of the Range Rover Evoque are 4531mm/1904mm/1650mm, which are official data. The length of the Range Rover Evoque refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle support plane. The turbocharged engine of the Range Rover Evoque has a maximum power of 147kW and a maximum torque of 320 N·m. The maximum power speed of this engine is 5500 rpm, and the maximum torque speed is 1200-4000 rpm. It is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with an automatic transmission (AT). The state has relevant regulations regarding vehicle dimensions. According to the national standard "GB1589-89" issued, the total width of a vehicle does not include rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, in the national standard, the significance of vehicle width data lies in providing enough space during overtaking, avoiding accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the state stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of relevant public roads.

What Causes the Sound of Grinding Brake Discs When the Car Moves?

When the car starts, the sound of grinding brake discs is caused by the friction material in the brake pads being too hard. Below is an introduction to brake pads: Concept: A brake disc, simply put, is a round disc that rotates when the car moves. The brake caliper clamps the brake disc to generate braking force. When the brakes are applied, the caliper clamps the brake disc to slow down or stop the car. Brake discs provide effective braking and are easier to maintain compared to drum brakes. Function: Brake pads definitely serve a braking function, with their braking force coming from the brake caliper. Generally, the brake caliper fixes the part where the inner brake piston pump is located, while the outer part is a clamp-like structure. The inner brake pad is fixed on the piston pump, and the outer brake pad is fixed on the outer part of the caliper. The piston is pushed by the pressure from the brake fluid line, moving the inner brake pad, while the reaction force pulls the caliper, causing the outer brake pad to move inward. Both pads press against the brake disc, generating braking force through friction between the disc and the inner and outer pads. In this process, the piston is pushed by brake fluid, also known as hydraulic oil, which is used to assist the engine. For the handbrake, a cable is used through a lever mechanism to forcibly pull the brake pads, pressing them against the brake disc to generate braking force.

Do I Need to Turn on Bluetooth for ETC on Highways?

When using ETC on highways, there is no need to turn on the car's Bluetooth or mobile phone Bluetooth. The ETC junction box installed in our vehicles has a short-range communication response system inside, which automatically communicates with sensors on the road, and our vehicles and mobile phones do not need to turn on Bluetooth. ETC is currently provided by 8 domestic manufacturers, and some ETC terminals can only be installed via mobile Bluetooth during installation, but Bluetooth does not need to be turned on during use. ETC is the abbreviation for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp; a bank card for deducting highway tolls; the applicant must be between 18 and 60 years old; the vehicle must be registered under the applicant's name. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; the vehicle for which ETC is to be applied. How ETC works: The on-board electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane of the toll station, and uses computer networking technology to settle accounts with the bank in the background, allowing the vehicle to pay highway or bridge tolls without stopping when passing through highway or bridge toll stations. Benefits of installing ETC: Time-saving: eliminates the hassle of queuing and waiting; Green and environmentally friendly: green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions and pollution; Cost-saving: reduces costs, decreases the frequency of vehicle starts and stops, reduces wear and fuel consumption, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
