What Are the Benefits of Cleaning an Engine?

Cleaning an engine can remove sludge from oil passages and carbon deposits from piston rings, thereby maintaining the engine. Here are the benefits of engine cleaning: Cleaning sludge from oil passages: The engine block is filled with oil passages, and an engine cleaner can remove sludge and impurities from these passages to ensure the proper functioning of the engine's lubrication system. Cleaning carbon deposits from piston rings: When the engine cleaner is added to the oil, it cleans the carbon deposits from the piston rings and ring grooves as the oil spreads on the cylinder walls. Maintaining the engine: When sludge, carbon deposits, and other substances that affect the engine's normal operation are cleaned, the engine's performance can be improved, and its lifespan can be extended. Engine maintenance can be broadly categorized into the following types: Engine cleaning and maintenance: Its primary function is to clean the sludge inside the engine and add an oil protectant to extend the lifespan of engine components. Fuel intake system cleaning: The main purpose of this service is to clean carbon deposits from the fuel intake system. Catalytic converter cleaning: Its role is to clean carbon deposits from the surface of the catalytic converter and enhance its reduction capability.

Do I need to pull the handbrake after parallel parking?

Pulling the handbrake after parallel parking will result in point deduction, so it is not necessary to pull the handbrake. The point deduction items for parallel parking include the vehicle body crossing the line after stopping in the parking space, stopping midway, and the tires touching the lane boundary line while driving. Among these, if the vehicle body crosses the line after stopping in the parking space or stops midway, 100 points will be deducted directly, resulting in test failure. If the tires touch the lane boundary line while driving, 10 points will be deducted. Parallel parking is one of the contents of the second subject of the driver's license test. Parallel parking is becoming increasingly common in cities, especially when parking spaces in formal parking lots are becoming more scarce. Many places have turned the original streets into parking spaces, forming "parallel parking spaces". After the implementation of the new traffic regulations, parallel parking no longer uses poles but adopts ground markings as the boundary of the parking space. For students learning the C1 driver's license, the length of the parallel parking space is 1.5 times the length of the vehicle plus 1 meter. Drive the vehicle to the front of the parking space parallel to the direction of travel, then reverse into the parking space to the right rear without any pauses. As long as the parallel parking is within this range and does not cross the boundary line of the parking space, it is considered a pass.

How Often Should a Car Air Filter Be Replaced?

The air filter should normally be replaced according to the maintenance manual or usage conditions, typically every 10,000-20,000 kilometers or once a year. If the driving conditions involve a lot of dust, it should be inspected and replaced as needed, usually checked every six months. During inspection, clean any debris around the air filter to reduce the buildup of throttle sludge. Function of the air filter: It filters out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing floating dust from being sucked into the engine, which accelerates wear on the piston group and cylinder. Air filter: It is a type of filter, also known as an air cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. The engine inhales a large amount of air during operation. If the air is not filtered, suspended dust in the air can be sucked into the cylinder, accelerating wear on the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand from the air, ensuring sufficient and clean air enters the cylinder. Dirty air filter: Using an overly dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, the air filter must be kept clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air entering the cylinder to reduce early wear on the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have little dust and minor clogging, it can be cleaned by blowing compressed air from the inside out and reused. An excessively dirty air filter should be replaced promptly.

How Many Questions Are There in the Traffic Rules Subject 1 Exam?

The Subject 1 exam for the driver's license consists of 100 questions, according to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses." It includes single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driver's license assessment. The exam content covers driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is computer-based with a time limit of 45 minutes. Subject 1 exam content includes: driver's license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and cargo vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses.

Can the Compulsory Traffic Insurance Cover a Broken Car Windshield?

No, the Compulsory Traffic Insurance does not cover the repair costs for your own car's broken windshield, as it is designed to compensate for damages to third-party vehicles and individuals. To claim for your vehicle's damage, you must have purchased a separate vehicle damage insurance. The Compulsory Traffic Insurance is mandatory by the state, and without it, you cannot legally drive on the road. According to the "Road Traffic Safety Law," the traffic management department of the public security authority may detain the motor vehicle, notify the party to provide the corresponding license, mark, or complete the necessary procedures, and may issue a warning or impose a fine ranging from 20 to 200 yuan. Compulsory Traffic Insurance for Vehicles: The full name of the Compulsory Traffic Insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates within the liability limits for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents involving the insured motor vehicle. The premium is based on the nationally unified standard rates. However, the price of Compulsory Traffic Insurance varies for different vehicle types, mainly influenced by the number of car seats. Compared to the over 20 exemption clauses in commercial third-party liability insurance, the exemption scope of Compulsory Traffic Insurance covers losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses from accidents, offering much broader coverage. Moreover, regardless of whether the insured vehicle is at fault in the accident, the Compulsory Traffic Insurance will compensate within the liability limits, with no deductible or exemption. Introduction to Electronic Insurance Policies: An electronic insurance policy refers to a digital policy issued by an insurance company using digital signature software that complies with the PKI system and an enterprise digital certificate, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the formal written proof of the insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks on paper; Saves time and is convenient, not restricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance and resending, eliminating worries about losing it. If a paper version is needed offline, it can also be printed or mailed; Facilitates management, as electronic standardization makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.
