On highways, the standard width of a single lane is 3.75m, with an emergency stopping strip width of 3.5m. For multi-lane roads above the third grade, the width of each motor vehicle lane ranges from 3.5 to 3.75 meters. The relevant regulations on lane width and the width of toll stations are as follows: Relevant regulations on lane width: According to the "Technical Standards for Highway Engineering": the lane width for highways designed at 120km/h is 3.75m, with an emergency stopping strip width of 3.5m. Since the maximum design speed of highways in China currently does not exceed 120km/h, the above standards are generally adopted. Toll station lane width: Additionally, the width of each lane at highway toll stations is 2.5 meters, and if necessary, an extra-wide lane of over 3.5 meters may be established. However, regardless of the width at any location on the highway, drivers must operate their vehicles accordingly. Only by adhering to laws and regulations can drivers effectively prevent traffic accidents on highways.

What Causes Engine Oil to Spray from the Exhaust Pipe?

Reasons for engine oil spraying from the car's exhaust pipe are as follows: 1. Failure of pistons, cylinder liners, piston pins, or piston rings, resulting in loss of original sealing effect, leading to oil spray from the exhaust pipe. 2. Severe wear between the valve stem and valve guide, creating excessive clearance, causing oil spray from the exhaust pipe. 3. If the car's exhaust pipe is connected to the upper part, the issue may lie with the valve oil seal. 4. If the vehicle has just been serviced, residual oil in the cylinder may cause temporary oil discharge, which is normal. However, if oil leakage persists after prolonged operation post-repair, it may be due to wear of the turbocharger's floating bearing seal ring. In case of any of the above issues, regardless of the cause, it is best to leave it to professionals. This process requires systematic troubleshooting, and any errors during disassembly or assembly can lead to further vehicle malfunctions.

Is it necessary to keep a life jacket in the car?

It is not necessary to keep a life jacket in the car. Car toolkit: Every car comes with a toolkit, which usually contains some basic tools, including wrenches, screwdrivers, wheel rim keys, etc. Car owners should regularly organize and check them. It is best to clean them after each use to extend the lifespan of the tools. Spare tire: Spare tires are often forgotten under the trunk and lack maintenance. Therefore, it is recommended that car owners check the spare tire regularly every three months and inflate it if necessary. First aid kit: This is an emergency car equipment that most drivers do not have. In Audi cars, you can find a factory-equipped first aid kit. The kit should contain bandages, gauze, disinfectants, and other emergency medicines to provide first aid in case of an accident. At the same time, the first aid kit should be checked and cleaned every six months. Jack: A jack is an indispensable tool for changing tires, and almost all car manufacturers provide a set of jacks with the car. When buying a used car, be sure to check if the jack is intact, as the factory-provided jack is lightweight and easy to use. Factory car manual: Keeping the manual in the car for a long time has the advantage of clearly understanding the various conditions of the car. When a problem occurs, the cause can be immediately identified from the manual.

Will driving with a small cut on the tire have any impact?

Driving with a small cut on the tire will have an impact. Rubber Strip Plug Repair: If the tire is punctured by a nail but is not losing air, it generally means the nail hasn't penetrated the tire completely, or the nail is temporarily blocking the air leak. In this case, the most effective method is to insert a special rubber strip into the punctured area, commonly known as the "rubber strip plug method." This only takes a few minutes and doesn't require removing the tire from the rim. However, the drawback of this method is that it's not very durable, so the vehicle owner should drive to a repair shop as soon as possible for a proper tire repair. Patch Repair Method: If the tire loses air quickly after being punctured and there's no spare tire available, you can remove the tire, locate the puncture, and apply a special tire repair agent to the inner layer of the tire. The tire repair agent is a non-toxic, odorless, non-flammable, and non-sticky liquid that can both repair the tire and inflate it. When the tire is punctured and loses air, simply connect the repair agent to the tire and press the valve. It will automatically add compressed air to the tire while injecting a white, hairspray-like repair adhesive. However, if the puncture diameter exceeds 6mm, this small tool won't be effective.

What is the lifespan of the timing chain in the eighth-generation Accord?

The lifespan of the Accord's timing chain is approximately 180,000 to 200,000 kilometers. Timing Chain: The timing chain operates by connecting the crankshaft and camshaft sprockets with high-strength metal chains to ensure synchronized movement. Due to the high-speed operation between metal components, which leads to rapid wear and high temperatures, a corresponding lubrication system must be designed for cooling and lubrication. Function of the Timing Chain: The "timing belt" or "timing chain" is a critical component of the engine. Its primary function is to drive the engine's valve train, ensuring that the intake and exhaust valves open and close at the appropriate times, allowing the engine cylinders to properly intake and exhaust air.
