Is it no longer necessary to display the 2021 inspection sticker and compulsory insurance sticker?

First, the compulsory insurance sticker can be omitted in regions where electronic insurance policies have been implemented. As for the inspection sticker, it was fully digitized in 2020 and replaced by electronic inspection qualification certificates, so it is no longer required to display the inspection sticker. Relevant requirements for the digitization of motor vehicle inspection marks stipulate: 1. For vehicles exempt from inspection within 6 months: Vehicles that have already obtained electronic inspection qualification certificates do not need to display paper stickers. Traffic police will verify the inspection status of vehicles through law enforcement terminals during traffic management. 2. Inspection qualification: Motor vehicles must pass regular inspections, including exhaust emissions, vehicle appearance, lights, brakes, chassis, etc., and must have no traffic violation records to receive the inspection qualification mark. All inspection dates are based on the registration date on the vehicle's license, and motor vehicles must undergo safety technical inspections according to the following periods from the date of registration, referred to as 'annual inspection' or 'annual review'.

How to Coordinate the Clutch and Brake?

Methods for coordinating the clutch and brake: 1. Automatic transmission cars do not have a clutch pedal, so simply press the brake directly; 2. When driving at high speed or normal speed, if the intention is only to slow down, there is no need to press the clutch; 3. When approaching a curve, first press the brake to reduce speed. After navigating the curve and confirming there are no obstacles, release the brake and press the accelerator to speed up without pressing the clutch. If there is an obstacle right after the curve, press the clutch and shift to a lower gear; 4. When descending a long or steep slope, do not press the clutch; instead, use the engine's traction for braking; 5. When intending to stop, first press the brake to reduce speed and then press the clutch; 6. In heavy traffic with frequent stops and short following distances, press both the clutch and brake simultaneously each time you brake; 7. In emergency situations, press both the brake and clutch together. ABS (Anti-lock Braking System) only becomes effective when the wheels are about to stop. If only the brake is pressed, the engine might stall, but the vehicle could still skid. In this scenario, ABS would fail completely due to the engine stalling. By pressing the clutch simultaneously, the connection between the engine and wheels is disconnected, allowing the wheels to quickly reach the locking threshold, thereby enabling the ABS system to activate promptly.

Should the Audi A4L use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the Audi A4L should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can still be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Audi A4L occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the lowered ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will appear during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What Causes the Formation of Oil Film on Windshields?

Reasons for the formation of oil film on car glass: vehicle exhaust, oil smoke pollution, as well as insect remains, bird droppings, tree resin, or fruit residues. The oil film is a layer of oily substance formed by various pollutants adhering to the surface of the car glass. This layer is exceptionally stubborn and generally difficult to remove. However, if not addressed promptly, it will inevitably affect driving. Causes of oil film formation: Vehicle exhaust: Car exhaust can adhere to the glass, forming an oil film. Oil smoke pollution: If oil smoke contaminants are left untreated for a long time, they can turn into greasy residue. Insect remains, bird droppings, tree resin, or fruit residues: Insect remains and bird droppings are highly corrosive. If not cleaned off the glass, they can harden and form an oil film. Methods to remove oil film: Use a specialized oil film cleaner. Spray the cleaner evenly on the glass and wipe it with a car wash towel or sponge. Use toothpaste for cleaning. Toothpaste contains abrasive particles that can help polish the surface. Applying it evenly on the glass can clean the pores on the glass surface and remove the oil film. Use an eraser, car wash clay, or newspaper for wiping. An eraser and car wash clay can scrub off the oil film, while newspaper has some oil-absorbing properties. Dampening it with water and wiping repeatedly can also remove the oil film.

What brand is the 21 Geely Binrui CVT transmission?

"The Binrui CVT transmission comes from Punch Powertrain in Belgium. Founded in 1972 and headquartered in Belgium, Punch Powertrain has over 40 years of leading experience in the design and production of CVT continuously variable transmissions. The company is engaged in the development, production, and sales of powertrains for new energy vehicles, as well as the development, production, and supply of dual-clutch transmissions (DCT) and their components. The Binrui transmission is an 8-speed CVT continuously variable transmission produced by Punch Powertrain. Unlike traditional automatic transmissions with fixed gear ratios, a CVT does not have distinct gear steps. It operates similarly to an automatic transmission but provides a seamless and continuous power delivery due to its stepless ratio changes. For daily use of the Binrui CVT transmission, pay attention to the following points: Do not delay transmission fluid changes for extended periods. Prolonged use of old transmission fluid can damage internal components such as bearings and the transmission casing. Avoid coasting in neutral for long durations. While some experienced drivers coast in neutral with manual transmissions, doing so in an automatic/CVT can cause overheating and harsh engagement when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Abrupt gear changes while moving can severely damage transmission gears and lead to gear grinding over time. Avoid frequent steep hill climbs in Drive (D). Automatic/CVT vehicles may overheat under heavy load or upshift prematurely, reducing climbing power. Use manual mode to lock lower gears or sport mode to protect the transmission. Do not tow the vehicle long distances with driven wheels on the ground. If the vehicle breaks down, use a flatbed tow truck with the transmission in Neutral (N). Towing with a rope or with wheels on the ground can damage the transmission."
