Different in depth, cannot be replaced. Reasons: The diameter of the tire will increase if changed to 825, first the odometer needs to be replaced, the engine power will not keep up, the required torque will increase, which also affects the vehicle structure. It will not pass the vehicle inspection. The most basic requirement for tire upgrade is that the tire diameter is equal or similar (cannot be higher than the original by 1%, cannot be lower than the original by 2%). The original tire diameter is 750mm, and you want to replace it with 825mm, (825-750)/825=9%, so it has far exceeded the diameter requirement. Tire upgrade has nothing to do with the rim diameter, but is related to the total diameter.

What is the maximum mileage a car can run before being scrapped?

Non-commercial vehicles and commercial vehicles have different scrapping periods, as detailed below: Scrapping regulations for non-commercial vehicles: For household 5-seat cars and 7-seat SUVs, non-commercial small and micro-sized cars have no usage age limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. In addition to the above vehicles, small and micro-sized non-commercial passenger cars, large non-commercial cars, and wheeled special machinery vehicles also have no usage age limit. Common scrapping regulations for commercial vehicles: Small and micro-sized taxi passenger cars have a scrapping period of 8 years, medium-sized taxi passenger cars have a scrapping period of 10 years, and large taxi passenger cars have a scrapping period of 12 years. Public transport passenger cars have a scrapping period of 13 years, other small and micro-sized commercial passenger cars have a scrapping period of 10 years, and large and medium-sized commercial passenger cars have a scrapping period of 15 years. Micro-sized commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out a copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" and stamp the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping age. For vehicles that have not reached the scrapping age, after inspection by the motor vehicle inspection office, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Inspection Form", "Scrapped Vehicle Recycling Certificate", and vehicle dismantling photos to the motor vehicle inspection office for verification and signature. The license plates will be reclaimed, and the application will be submitted for approval according to regulations, followed by the scrapping registration. Special notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle cannot be driven back to the registration location due to damage, the owner can hand over the scrapped vehicle to a local motor vehicle recycling company. Commercial vehicles converted to non-commercial vehicles must be scrapped according to the original commercial vehicle scrapping time. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of the motor vehicle registration, the original owner can apply to use the original license plate number when registering a new vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation; (2) The owner must have owned the original vehicle for more than three years.

What does e-CVT continuously variable transmission mean?

e-CVT continuously variable transmission refers to a hybrid transmission integrated with an electric motor, which is a specialized transmission for hybrid vehicles. Here is some relevant information about the e-CVT continuously variable transmission: 1. Structure: ECVT does not have complex mechanisms such as clutches, torque converters, or gear shaft sets found in traditional transmission systems. It consists of a set of planetary gears and two electric motors. 2. Principle: ECVT not only transmits power but also couples the energy of the engine and the electric motor to achieve power output. It is essentially a power combination system, specifically designed as a power distribution mechanism for hybrid vehicles, hence also referred to as PSD, or Power Split Device.

What is the difference between dual exhaust pipes and a single one?

The differences between dual exhaust pipes and a single one are as follows: 1. Different displacement: A single exhaust pipe is typically found in small-displacement vehicles, while dual exhaust pipes are used in large-displacement vehicles. 2. Different engine structure: Vehicles with a single exhaust pipe usually employ a four-cylinder engine, whereas vehicles with dual exhaust pipes generally use a V-type six-cylinder or larger engine. The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also part of the exhaust system. Exhaust pipes generally consist of a front exhaust pipe and a rear exhaust pipe. 3. Function: The exhaust pipe serves as a device to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust muffler system.

What Causes Insufficient Purge Pump Speed?

Electrical Circuit Fault: Check the purge pump's wiring connections and plugs for any loose connections to confirm this issue. If there's a fault in the purge pump's wiring, it can lead to insufficient power supply to the pump, resulting in reduced pump speed. Air Leak in the Hose: Inspect the hose connections between the purge pump and the charcoal canister for looseness and check the hose surface for any damage. If found, it can cause air leaks in the hose, leading to insufficient purge pump speed. Purge Pump Failure: Use a vehicle diagnostic tool to read the purge pump's data stream and analyze whether its operating condition is normal. If there are no air leaks in the hose and the wiring connections are secure, the purge pump itself may be faulty.

Is It Serious If a Small Amount of Rainwater Gets into the Fuel Tank?

If only a very small amount of rainwater enters the fuel tank, it will not cause serious consequences. However, if a large amount of rainwater enters, the engine may experience issues such as shaking, poor acceleration, knocking, cylinder knocking, and fuel line blockage. In such cases, the following methods can be considered for handling: 1. No obvious symptoms: If there are no obvious symptoms after rainwater enters the fuel tank, a fuel tank water remover can be considered. A qualified fuel tank water remover can indeed mix oil and water to remove accumulated water in the fuel tank, but care should be taken to choose the right product. 2. Obvious symptoms: If the impact on the engine is severe after water ingress, it is necessary to dismantle the fuel tank for cleaning and inspect the fuel lines, filters, fuel injectors, etc.
