Why Can You Smell Gasoline Inside a Car?

What lights should be turned on when a motor vehicle exits the highway?

When a motor vehicle exits the highway, the turn signal should be activated. Before driving off the highway, the driver needs to turn on the vehicle's turn signal and ensure there are no vehicles behind before exiting. The turn signal is an important indicator light that is activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. Vehicle turn signals are divided into left and right turn signals. How to use turn signals: 1. When parking on the roadside, the driver should first turn on the right turn signal to alert vehicles behind, preventing rear-end collisions or scrapes during parking; 2. When overtaking or changing lanes, the driver should first turn on the left turn signal and turn it off after completing the maneuver.

What are the requirements for tire tread patterns in vehicle annual inspections?

Annual inspection requirements for vehicle tires are: tires must not be excessively worn; tire tread patterns must not be inconsistent; the tread patterns of all four wheels should be consistent, or at least the front two or rear two should match, but left and right tread patterns must not differ. The functions of tires are: to transmit driving force, braking force, and steering force for vehicle operation; to support vehicle loads; to mitigate and absorb vibrations and impacts during driving. Tire maintenance methods include: regularly removing stones stuck in tire grooves; minimizing exposure to direct sunlight; promptly checking tire pressure; paying attention to suspension maintenance; periodically inspecting front wheel alignment; adopting careful driving habits by choosing smooth road surfaces, avoiding objects that could puncture or scratch tires, and steering clear of chemical spills that may corrode tires. Annual inspections are conducted to: Check whether the engine, chassis, body, and auxiliary equipment are clean, intact, and functional; whether the vehicle's paintwork is symmetrical and aesthetically pleasing; whether major standard components have been replaced and match the initial inspection records. Verify whether the vehicle's braking performance, turning maneuverability, lighting, exhaust system, and other safety factors comply with the "Technical Requirements for Safe Operation of Motor Vehicles." Examine whether the vehicle has been modified, altered, or reconstructed; whether all records in the vehicle license, license plates, and vehicle files match the current condition and show any changes; and whether necessary approval, alteration, or modification procedures have been completed. Inspect whether the printed license plate numbers on the vehicle, the vehicle license, and the enlarged license plate characters are damaged or illegible, and whether they need replacement.

How often should fuel additives be used?

Fuel additives should be used every 5,000 to 10,000 kilometers. Gasoline additives are functional substances added to gasoline to compensate for certain deficiencies in gasoline properties and to impart new and superior characteristics. They offer benefits such as enhancing power, removing carbon deposits, cleaning the fuel system, saving fuel, and preventing rust. Gasoline additives are categorized into cleaning, maintenance, and fuel-saving types. Purchasing legitimate gasoline additives can provide certain benefits for your vehicle. Fuel additives can improve octane and cetane values, offering functions such as boosting power, promoting combustion efficiency, resisting oxidation and wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubrication.

What do the three locks of an off-road vehicle refer to?

Off-road vehicle three locks refer to the central differential lock, rear differential lock, and front differential lock of an off-road vehicle. For off-road vehicles, having these three locks is equivalent to being the king of off-roading. Currently, only the Mercedes G, Defender, and Jeep Rubicon possess these three locks. Information about the three locks of off-road vehicles is as follows: 1. Central differential lock: It can make the front and rear wheels rotate at the same speed when the wheels slip, but this is limited to mild road conditions. If it's a cross-axle or artillery shell pit, the central differential lock is not very effective. 2. Rear differential lock: It can make the rear wheels rotate at the same speed as the front axle. Specifically, when an off-road vehicle is driving on a cross-axle or artillery shell pit, and only one wheel has traction while the other is suspended, the vehicle still has enough power to move forward. This lock is therefore called the soul of the off-road vehicle. 3. Front differential lock: When one side of the vehicle is suspended, the front differential lock can make all the wheels of the vehicle receive the same power. Therefore, the front differential lock is called the life-saving component of the off-road vehicle.

How to Distinguish Between Retreaded Tires and New Tires?

The differences between retreaded tires and new tires can be identified through the following four methods: 1. Observe the tread pattern, color, and gloss: In terms of tread patterns, generally, due to the irregular processing of inferior retreaded tires, the tread grooves are relatively shallow. In terms of color, inferior retreaded tires appear bright and shiny, while regular ones are relatively dull. Retreaded tires have a duller color and gloss. 2. Examine the joint between the tread and the sidewall: First, check the sidewall for complete markings. Various tire manufacturers have tread pattern code markings; verify if the pattern code matches the tire tread. Next, inspect the shoulder area where the tread meets the tire body for smoothness. Retreaded tires have self-made treads attached to old tire bodies, resulting in less smooth and rounded joints between the tread and sidewall compared to new tires, with visible bonding marks on the sidewall. 3. Test the tire elasticity: Gently scratch the tire with a key. New tires have good elasticity, and the scratch will disappear quickly; retreaded tires have poor elasticity and will leave a mark. 4. Look for tire hairs: New tires have small hairs that gradually disappear after driving 5 to 10 kilometers; retreaded tires lack these hairs and cannot fake them.

Where to Find the Vehicle Model Code?

Locations to check the vehicle model code: 1. In China, the Vehicle Identification Number (VIN) is mostly located on the left side of the dashboard, below the windshield; 2. On the motor vehicle license, the new license usually prints the VIN code in the vehicle identification number column; 3. Other places: such as various nameplates in the engine compartment, on the driver's side door pillar, or on the insurance policy. VIN is the abbreviation for Vehicle Identification Number, which contains information about the vehicle's manufacturer, year, model, body type and code, engine code, and assembly location, consisting of a total of 17 characters.
