What is the real reputation of the Envision 1.5T?

About the real reputation of the Envision 1.5T, the relevant introduction is as follows: 1. Advantages: The 1.5T Envision offers high cost performance, and its power can meet household needs. It comes with abundant configurations, including standard features such as 6 airbags, tire pressure monitoring, ESP, cruise control, hill start assist, panoramic sunroof, keyless system, multifunction steering wheel, active noise cancellation, automatic headlights, power-folding mirrors, and automatic air conditioning. 2. Disadvantages: The 2.0T model has relatively high fuel consumption, with an average real-world fuel consumption of around 12-13L. The 1.5T model has issues with its powertrain; it is paired with a dual-clutch transmission, which causes jerky gear shifts at low speeds and noise problems. Additionally, the maintenance costs are relatively high.

Can Sinopec and Shell gasoline be mixed?

Gasoline can be mixed, and here are the relevant details: Gasoline can be mixed: For gasoline from different companies, the country has strictly standardized the main components of additives in gasoline. Even if mixed, it will not cause harm. In emergency situations, Sinopec and PetroChina gasoline can be mixed occasionally, but from a long-term perspective, it is not recommended to mix gasoline from different oil companies. Gasoline composition: The main components of gasoline are C5-C12 aliphatic hydrocarbons and cycloalkanes, as well as a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 89, 92, and 95 based on the octane number. Gasoline is produced by refining different gasoline components obtained from petroleum refining, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, and then blending them with high-octane components. It is mainly used as fuel for spark-ignition internal combustion engines in automobiles.

How to Choose SUV Tires?

Here are the detailed introductions and selection methods for SUV tires: 1. HT Tires: Highway Terrain tires, mainly used for urban SUV models driving on paved roads. Paved roads can be simply understood as cement and asphalt surfaces, while unpaved roads refer to gravel and mud roads. HT off-road tires are primarily designed for urban SUV models, ensuring comfort and stability for city SUVs. 2. AT Tires: AT (All-Terrain) tires, also known as all-terrain off-road tires, allow SUVs equipped with these tires to perform well on both paved and unpaved roads. AT tires have more prominent off-road capabilities compared to HP tires. AT tires feature larger tread blocks and deeper longitudinal and lateral grooves than HT tires, with relatively harder rubber in the tire body. 3. MT Tires: MT (Mud-Terrain) tires have a very distinct off-road style compared to HT and AT tires. Their tread patterns are very exaggerated, with large tread blocks and deep, wide longitudinal and lateral grooves. Mud-Terrain refers to muddy road conditions, and they can also be called mountain off-road tires.

What is the oil from tire pyrolysis used for?

Tire pyrolysis oil has a high calorific value and can directly replace fuel oil for industrial or boiler heating purposes, such as in cement plants, steel mills, glass factories, etc. It can also be refined into diesel for use in diesel power plants, heavy machinery, and agricultural machinery. Here is some extended information about automotive tires: 1. Impact of tire size on vehicles: Tire size affects a car's acceleration, stability, and fuel consumption. The relationship between tire size and driving speed is complex. Small-displacement vehicles may struggle to move if fitted with oversized tires due to insufficient power, while large-displacement vehicles may have their power output limited by excessively small tires, affecting speed. Bigger and wider tires are not necessarily better. When driving on bumpy roads or over speed bumps, oversized tires can easily cause friction interference with the wheel arches. 2. Functions of tires: Tires transmit driving force, braking force, and steering force to enable vehicle operation; they support vehicle loads; and they mitigate and absorb vibrations and impacts during driving to prevent severe vibrations from damaging automotive components.

What is the difference between shaft drive and chain drive?

The differences between shaft drive and chain drive are as follows: 1. Different transmission efficiency: The mechanical efficiency of shaft drive gears exceeds 99%, while that of chains is only 95%. In other words, when the same force is applied to the same bicycle, a shaft-driven bicycle can travel farther than a chain-driven one. 2. Different lifespan: The service life of shaft drive gears is several times longer than that of chain drives, with a mileage that can reach hundreds of thousands of kilometers, generally requiring no maintenance for 10 years. In contrast, chain-driven bicycles will inevitably experience chain elongation and breakage after a period of use. 3. Different lubrication environments: The gears of a shaft-driven bicycle are enclosed in a sturdy cast aluminum alloy shell, with the entire transmission system operating in a fully sealed environment where mud and sand cannot enter. It comes with oil rust and lubricating oil, and the oil will not leak out. On the other hand, the chain of a chain-driven bicycle is partially exposed during operation, making it easy for lubricants to leak out. Therefore, in most cases, chains without lubricating oil are prone to rust.

Is it better to use 92 or 95 octane gasoline for the Geely Vision?

Geely Vision is equipped with a 1.5-liter naturally aspirated engine across the entire lineup, so this vehicle can use 92 octane gasoline. Gasoline with different octane ratings has different levels of octane; the higher the octane rating, the higher the octane value, and gasoline with higher octane values is more stable. Generally, 92 octane gasoline is sufficient for naturally aspirated engines in family cars. Here is some information about the Geely Vision: 1. The Geely Vision is a compact sedan under the Geely brand. Its 1.5-liter naturally aspirated engine delivers 109 horsepower and a maximum torque of 142 Nm. The engine reaches its maximum power at 6000 rpm and its maximum torque at 4400 rpm. This engine features multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. 2. The Geely Vision's engine is paired with either a 5-speed manual transmission or a CVT. The CVT is a common type of automatic transmission that is very suitable for family cars. The front suspension of the Geely Vision uses a MacPherson independent suspension, while the rear suspension employs a torsion beam non-independent suspension.
