Car acceleration slow when refueling reasons are as follows: 1. Clutch slipping: Clutch slipping mainly manifests as when the car accelerates during driving, the speed cannot increase with the rise of engine speed, and the engine's power cannot be fully transmitted to the driving wheels, resulting in weak driving. 2. Engine system failure: The power source is the combustion of fuel, the engine is responsible for providing fuel and converting chemical energy into mechanical energy, so when the car has weak acceleration and slow speed, the engine system should also be a key point for inspection. 3. Oil circuit problems: If the engine oil is insufficient for a long time, the lighter ones will have insufficient power and increased fuel consumption; the heavier ones will cause the piston to hit its door, causing mechanical damage to related connecting parts. In addition, fuel pump failure and fuel filter blockage will also cause the engine power to drop.

I've seen this issue of slow acceleration when refueling quite a few times as a mechanic, and it's mostly related to the engine's fuel system. When the fuel filter is clogged, gasoline flow becomes restricted, leading to insufficient fuel injection from the injectors, resulting in poor power response when stepping on the gas. Additionally, an aging fuel pump with inadequate pressure can cause sluggish fuel delivery. A dirty air filter can also contribute to the problem by reducing air intake and making the engine work less efficiently, thus hindering acceleration. It's recommended to first check the air filter and fuel filter for cleanliness yourself. If they're covered in dust or contaminants, try replacing them with new ones. If that doesn't help, test whether the fuel pressure is normal to avoid power loss caused by carbon buildup or clogged injectors. In short, timely maintenance of the fuel system can resolve most acceleration issues—don't wait until it affects driving safety to make repairs.

What is the difference between two-lane and three-lane highways?

On a two-lane highway, the speed limit for the leftmost lane is 100-120 km/h, while the middle lane has a speed limit of 60-100 km/h. For a three-lane highway, the speed limits from left to right are 110-120 km/h, 90-110 km/h, and 60-90 km/h respectively. Below are some important considerations for highway driving: 1. Speed limit regulations: Strictly adhere to the speed limit regulations on highways to avoid accidents caused by speeding. Driving too slowly can hinder the normal flow of other vehicles. In rainy or snowy conditions, the speed should be reduced accordingly. 2. Maintaining distance: Always maintain a safe longitudinal distance between vehicles. Generally, on dry roads with good braking conditions, the distance (in meters) should not be less than the speed (in km/h). Pay attention to roadside distance markers at all times. In rainy, foggy, snowy, or wet road conditions, the distance between vehicles should be more than doubled.

What kind of people usually drive the Borui?

Most Borui drivers are college graduates who have been out of school for a few years. Here are some key features of the Borui: 1. Exterior: The Borui's appearance is as beautiful as a vibrant flower, exuding a youthful and sporty vibe that gives a sense of stability without losing passion. The front face features sharp headlights that are imposing enough to awe competitors, while the rear design harmoniously complements the front, creating a balanced and aesthetically pleasing look. 2. Powertrain: The Borui is equipped with a 1.8L inline 4-cylinder turbocharged engine, delivering a maximum power output of 135KW. A light tap on the accelerator brings a continuous surge of power, offering drivers an exceptional driving experience. With a maximum torque of 300 Nm, the Borui can accelerate from 0-100km/h in 8.4 seconds, which is quite comparable to its main rival, the Trumpchi GA6.

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.
