How to Open an ETC Device?

The method to open an ETC device is: 1. Use a hairdryer to heat the contact surface between the ETC device and the glass, softening the adhesive before gently removing it; 2. Soak a towel in hot water and apply it to the adhesive tape on the back of the device to heat it; 3. Use a scraper to remove the adhesive tape and take the device off. ETC, or Electronic Toll Collection, is a system that allows vehicles to pass through toll stations without stopping. It uses onboard equipment to identify the vehicle, record information, and automatically deduct the corresponding fee from a pre-linked IC card or bank card. ETC is a specialized road tolling method primarily used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion in cities.

The requirements for upgrading from a C1 to a B1 license are: 1. The C1 license must have been held for at least 3 years; 2. The applicant must be between 21 and 50 years old, with a height of at least 155cm; 3. No full-point penalty record in the last 3 scoring cycles before application; 4. The ID card, driver's license, and residential address information must be consistent. The process for upgrading from C1 to B1 is: 1. Apply for the B1 driving category upgrade at the local vehicle management office of the household registration area; 2. Fill out the application form, submit the ID card and physical examination form, and provide the current motor vehicle driver's license; 3. Attend the theoretical and practical exams as scheduled; 4. The new driver's license will be issued by the applying vehicle management office within 7 working days after passing the exams.

Can 92 and 95 octane gasoline be mixed together?

92 and 95 octane gasoline should not be mixed together. Long-term mixing of different octane ratings will affect the service life of the car's ignition system, fuel injectors, and spark plugs. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation or cracking, which can be used as fuel and appears as a transparent liquid. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. The main difference between the two lies in the purity of isooctane. The higher the purity of isooctane, the stronger the anti-knock performance of the gasoline.

What is the normal and suitable tire pressure for the Envision in summer?

The recommended tire pressure for the Envision in summer is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. The Envision comes standard with a tire pressure display function, allowing you to check the tire pressure directly on the dashboard. Additionally, the standard tire pressure for the Envision can be found on the vehicle's nameplate, usually located below the door frame on the passenger side, and is also detailed in the user manual. Generally, a tire pressure above 2.8 bar is considered too high, while a tire pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a tire blowout. If the tire pressure monitoring indicator light turns on (a yellow symbol with an irregular circle, no seal on top, four small spikes at the bottom, and an exclamation mark inside), it generally indicates one of the following three reasons: Abnormal tire pressure: Usually triggers an alarm when pressure is below 1.8 bar or above 3.0 bar. In this case, the tire needs to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to turn on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will turn on. In this case, the only solution is to replace the sensor with a new one.

What Type of Cars Use 85 Octane Gasoline?

85 octane gasoline is suitable for cars with an engine compression ratio below 10. The octane rating of gasoline represents its octane number, with higher ratings indicating higher octane content. Gasoline is a volatile and flammable liquid hydrocarbon mixture obtained from petroleum through distillation, cracking, or pyrolysis, and is used as fuel. It appears as a transparent liquid and primarily consists of aliphatic hydrocarbons, naphthenes, and a certain amount of aromatic hydrocarbons. Gasoline can be classified based on different sources into: straight-run gasoline, catalytic cracking gasoline, thermal cracking gasoline, reforming gasoline, coking gasoline, alkylation gasoline, isomerization gasoline, aromatization gasoline, etherification gasoline, and polymerization gasoline. The characteristics of gasoline include: 1. Volatility; 2. Stability; 3. Anti-knock properties; 4. Corrosiveness; 5. Cleanliness.
