Cleaning carbon deposits will not block the catalytic converter. This is because fuel additives clean carbon deposits gradually, and the particles removed are very small, so they will not cause the catalytic converter to become blocked. Below is an introduction to the automotive catalytic converter: 1. Appearance: The catalytic converter looks like a metal can from the outside, but inside it contains a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. 2. Exhaust Gas Purification Function: The precious metals act as catalysts, reducing HC and CO in the exhaust gases into water and CO2, while decomposing NOx into nitrogen and oxygen. This is the exhaust gas purification function of the catalytic converter.

When is the scheduling time for Subject 2?

Subject 2 exam can be taken once, and those who fail can retake it once. If the retake is not attended or still failed, the exam process will be terminated, and the applicant should reschedule the exam after ten days. Here is additional information about Subject 2: 1. Retake time: The interval between each retake for Subject 2 and Subject 3 must be at least 10 working days, which is two weeks. The retake can only be scheduled four working days after the ten-day period, meaning the earliest possible time is half a month later, as stipulated by the driving test regulations. 2. Scheduling limit: Within the validity period of the driving skill test permit, the number of scheduled exams for Subject 2 and Subject 3 road driving skill tests must not exceed five times. If the fifth scheduled exam is still failed, the results of other previously passed subjects will be invalidated.

Is the insurance automatically transferred when the car is sold?

It can be transferred, but you need to go through the endorsement procedures. Here is the relevant information: 1. Endorsement: Mainly involves modifying some policy elements, with the key changes being the insured and the vehicle owner. The required documents are relatively simple—just bring the insurance policy and the vehicle transfer certificate. The original owner can handle this at the insurance company’s service branch where the policy was originally purchased. 2. Applying for a refund: This means canceling the original auto insurance policy and terminating the previous contract. In this case, you only need to pay the premium from the start of the policy to the time of cancellation, and the insurance company will refund the remaining premium. The new owner can then purchase a new auto insurance policy from any insurance company. For this process, the required documents include the insurance policy and ID card. When applying for new insurance, only the new vehicle license or the vehicle transfer certificate is needed.

What does car mortgage release mean?

Mortgage release for vehicles refers to the deregistration of the mortgage for motor vehicles purchased with a mortgage loan, which means the removal of the mortgage at the vehicle management office for vehicles whose mortgage rights have been extinguished. Below are two methods for releasing a vehicle mortgage: 1. Owner-initiated mortgage release: The owner needs to provide their identity proof and that of the mortgagee (a copy of the bank's organization code certificate), a bank-issued power of attorney with an official seal, and the registration certificate (with mortgage release information annotated), then fill out forms at the vehicle management office. 2. Third-party authorized mortgage release: The third party needs to provide an authorization letter, identity proofs and copies of both the vehicle owner and the mortgagee; the "Motor Vehicle Mortgage Registration/Pledge Filing Application Form"; in cases where the mortgage is released through court mediation, ruling, or judgment, the vehicle owner or mortgagee must also submit the effective "Mediation Agreement," "Ruling," or "Judgment" issued by the court, along with the corresponding "Notice of Assistance in Execution" and the motor vehicle registration certificate.

Is the 700r16lt a fully steel-belted tire?

700r16lt is a fully steel-belted tire. Below is an introduction to automobile tire models: 1. Automobile tires: Tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the vehicle suspension to mitigate shocks during driving, ensuring good ride comfort and smoothness; ensuring excellent adhesion between the wheels and the road surface, improving traction, braking, and off-road capability; bearing the weight of the vehicle, the critical role of tires in automobiles is increasingly recognized. During tire usage, tire pressure is a crucial indicator. 2. Structural classification: Can be divided into ribbed pattern tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires. 3. Classification by type: Tires can be roughly categorized into 8 types based on vehicle type. Namely: PC – Passenger car tires; LT – Light truck tires; TB – Truck and bus tires; AG – Agricultural vehicle tires; OTR – Engineering vehicle tires; ID – Industrial vehicle tires; AC – Aircraft tires; MC – Motorcycle tires.

What is the ground clearance of the Enclave Plus?

The ground clearance of the Enclave Plus is 188mm. Below is relevant information about minimum ground clearance: 1. Definition: Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding wheels) and the supporting surface when fully loaded and stationary. It indicates the vehicle's ability to pass over obstacles like stones or tree stumps without collision. 2. Impact on driving: The smaller the ground clearance, the poorer the ability to overcome obstacles. Sedans typically operate on flat urban roads, hence their ground clearance is smaller. Off-road vehicles have greater minimum ground clearance to traverse larger obstacles.

Will a Plug-in Hybrid Vehicle Get Damaged If Not Charged for a Long Time?

A plug-in hybrid vehicle will automatically increase the engine power when the battery is depleted. The increased engine power is partially used for vehicle consumption, while the other part drives the generator to recharge the battery. Therefore, not charging the vehicle for a long time will not damage the battery or motor of a plug-in hybrid, although fuel consumption will be relatively higher. Additional details are as follows: 1. Usage in second- and third-tier cities: If a plug-in hybrid vehicle is used in second- or third-tier cities, the fuel-saving effect may not be as ideal. Due to the presence of the battery, plug-in hybrid vehicles are significantly heavier than traditional gasoline-powered cars. As a result, driving the same distance on highways or regular roads will consume more fuel compared to traditional gasoline-powered cars. 2. Impact of long-term non-charging: It is particularly important to note that the biggest issue with plug-in hybrid vehicles currently is the need to continuously charge the battery to ensure optimal performance. Therefore, long-term non-charging not only negatively affects the engine but also undermines the intended functionality of purchasing a plug-in hybrid vehicle.
