Fuel system cleaning is indeed necessary because gasoline contains certain impurities that can generate carbon deposits in the combustion chamber over time. As these deposits accumulate, they can impair combustion efficiency, thereby affecting engine performance and increasing fuel consumption. This can also lead to poor fuel injector atomization, resulting in issues such as reduced engine power, poor acceleration, and non-compliant exhaust emissions. Maintenance and cleaning of the fuel system: 1. Regularly add fuel system cleaners, opting for high-quality products: Generally, cleaning should be performed every 10,000 to 20,000 kilometers. The purpose is to effectively remove carbon deposits, sediments, and gum from the combustion chamber, intake valves, fuel injectors, and fuel lines during vehicle operation, ensuring the fuel system remains clean. 2. Use specialized equipment for cleaning: Non-disassembly cleaning is performed by adding a cleaning solution through a supply device, commonly referred to as "hanging an IV." The advantage is that it enables non-disassembly cleaning while the engine is running, protecting the engine and effectively avoiding damage caused by disassembly. Most 4S stores adopt this method.

What is the Difference Between a Hatchback and a Fastback?

"Fastback" refers to a styling design technique, while "hatchback" describes a body structure. Here are the relevant details: 1. Fastback: Fastback describes the exterior appearance, whereas hatchback refers to the structure. A fastback features a smooth line from the roofline to the rear hatch when viewed from the side, without a noticeable inflection point. 2. Hatchback: The side profile has smooth lines, giving it a more sporty appearance. Non-fastback models show a clear inflection point where the rear windshield meets the hatch when viewed from the side. 3. Key Differences: In a fastback, the roofline gradually slopes downward, and at the rear, the line drops sharply. Compared to conventional cars, this design results in relatively less headroom in the rear seats and reduced luggage space.

How Many Chances Are There for Subject 2 Test?

For the Subject 2 test, if you fail the first attempt, you can retake it once. If you do not participate in the retake or fail the retake, the current test session ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of rescheduled attempts for Subject 2 and Subject 3 road driving skill tests must not exceed five times. If the fifth rescheduled test is still failed, the passing scores of other subjects already taken will be invalidated. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for large vehicles (A1, A2, A3, B1, B2) include: pole test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, right-angle turning, narrow gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turns, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling. The test items for small vehicles (C1, C2) include: reversing into a garage, parallel parking, slope parking and starting (canceled for C2), right-angle turning, and curve driving (commonly known as S-curve), which are the five mandatory items (some regions also include a sixth item: highway toll card collection).

What to Do When the Brake Cable Doesn't Retract?

Brake cable not retracting is usually caused by issues like brake rusting. Rust removal is required. Below are the specific reasons for brake cable not retracting: 1. Brake rusted or severely worn: Remove the brake cable, drip a few drops of lubricating oil from the top of the cable housing, repeatedly pull and release the cable to lubricate the housing and increase its lubrication. If the effect is still poor after adding lubricating oil, the cable needs to be replaced. 2. Weak spring on the caliper: The return spring on the caliper, if not cleaned for a long time, may accumulate a large amount of dust and dirt, potentially affecting the cable's retraction. Cleaning the spring is necessary to ensure the brake cable's lubrication.
