Gasoline 92 is cheaper. Generally, the smaller the label, the cheaper it is. The price difference between 95 and 92 gasoline is usually around 8%. The differences between 95 and 92 gasoline are as follows: Different Octane Numbers: 95 gasoline consists of 95% isooctane and 3% n-heptane; 92 gasoline consists of 92% octane number and 8% n-heptane. Different Anti-knock Properties: Gasolines with different labels have different octane numbers. The higher the label, the higher the octane number, and the better the anti-knock property of the gasoline. Here are other aspects of gasoline: These two types of gasoline cannot be mixed, as it will lead to a large amount of combustion residues remaining. Over time, this will cause the engine to accumulate a lot of carbon deposits, affecting power, increasing fuel consumption, and disrupting the normal operation of the engine. Gasoline appears as a transparent, flammable liquid, obtained from petroleum refining through different gasoline components such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline. After refining, it is blended with high-octane components and mainly used as fuel for spark-ignition internal combustion engines in automobiles.

Can You Feel the Difference When Driving with On-Demand Four-Wheel Drive?

When driving with on-demand four-wheel drive, you won't notice whether it's two-wheel drive or four-wheel drive that's powering the vehicle. There are two main types of drivetrain configurations for cars: two-wheel drive and four-wheel drive. Four-wheel drive systems can be categorized based on the engine's placement and orientation, such as front-engine four-wheel drive, mid-engine four-wheel drive, and rear-engine four-wheel drive. Similarly, they can be transverse or longitudinal. Based on the distribution of driving force, four-wheel drive systems can be further divided into full-time four-wheel drive and part-time four-wheel drive. Full-time four-wheel drive: The engine's power is continuously distributed to all wheels. Full-time four-wheel drive is more expensive to manufacture, provides smooth power output, and offers excellent climbing ability and strong traction. However, its drawbacks include a bulky powertrain structure, low transmission efficiency, and higher fuel consumption. Part-time four-wheel drive: The engine's power is not continuously distributed to all wheels, and most of the time, it operates in two-wheel drive mode. Compared to full-time four-wheel drive, it is less costly and has lower fuel consumption. However, its climbing ability is not as strong as full-time four-wheel drive, and its stability is also inferior.

What is the reason for excessive free play in the steering wheel on arched roads?

The reason for excessive free play in the steering wheel on arched roads is due to gravity. The free play of the steering wheel refers to the idle rotation angle of the steering wheel when the steering wheels are in the straight driving position. There is inevitably some clearance between the components of the steering system, and the steering wheel must overcome these clearances before it can drive the steering wheels to turn. The following precautions are introduced: 1. Introduction 1: Before starting the engine, adjust the driver's seat and rearview mirrors, and check the instruments. When starting the engine, the gearshift lever should be in neutral or P position. After the engine starts, release the ignition switch promptly. 2. Introduction 2: Before starting, ensure that the doors are closed, and observe the traffic situation on the left rear side by turning your head to the left and using the rearview mirrors. Before starting, use the left turn signal for at least 3 seconds. 3. Introduction 3: When starting, release the parking brake and ensure the vehicle does not roll backward. Start in first gear, use the clutch semi-engagement to control the speed, and manage the accelerator pedal to prevent the engine speed from exceeding 2000 RPM. Also, pay attention to avoiding any vehicle malfunctions.

What are the 2.0 manual transmission cars?

2.0 manual transmission cars include: Kia Sportage, Mazda CX-30, Yusheng S350, Fengguang S560, SWM X7. Below are relevant details about manual transmission cars: 1. Composition: By switching different gear sets, gear ratio changes are achieved. As a key component in power distribution, the transmission must have two major parts: the power input shaft and output shaft, along with the gears that make up the transmission, which are the most basic components of a manual transmission. 2. Principle: The power input shaft is connected to the clutch, and the power transmitted from the clutch is directly passed to the gear set through the input shaft. The gear set consists of gears of different diameters, and different gear ratios achieve different power transmission effects. The gear shifting during normal driving refers to changing the gear ratio. 3. Function: Drivers can save fuel by selecting the appropriate gear. Manual transmission cars are often said to be more fuel-efficient because manual transmissions have higher transmission efficiency, which can reduce power loss. Driving a manual transmission car requires higher driving skills, and proper and timely gear selection is essential to truly save fuel.

Can a deformed rim still be used?

Deformed rims should not continue to be used. Here are the hazards after deformation: 1. When a car tire is fully inflated, the outer edge of the tire will tightly fit with the rim flange to prevent gas leakage from the tire. 2. If the rim flange is deformed due to collision, it will affect the tightness with the outer edge of the tire, causing slow leaks. Therefore, car owners should pay attention to avoiding collisions with the rim during daily use to prevent rim deformation. 3. If the tire wobbles, it will affect the dynamic balance and may cause vibrations at higher speeds. 4. If the steel rim is slightly deformed, the impact on air tightness is not significant, but there are always negative effects.

What brand is the Besturn B70 transmission?

Besturn B70 is equipped with Aisin's F21 six-speed automatic manual transmission, which further enhances comfort and handling, outperforming Mazda's five-speed automatic manual transmission. The vehicle exhibits excellent gearshift smoothness and overall drivability. The Besturn B70 is a product of FAW, classified as a mid-size sedan with the following dimensions: length 4810mm, width 1840mm, height 1455mm, wheelbase 2800mm, fuel tank capacity 50L, and curb weight 1440kg. The new-generation Besturn B70 is powered by a 1.5T turbocharged engine delivering maximum power of 124kW and peak torque of 258Nm. This engine features ultra-high-pressure direct injection with a thermal efficiency of 39%. It is paired with a 6-speed manual transmission. In terms of chassis design, the Besturn B70 utilizes the same large-area high-strength steel as the Mazda6, which not only improves chassis rigidity but also reduces overall vehicle weight. The suspension configuration varies by trim level: lower trims feature front MacPherson strut independent suspension with rear torsion beam non-independent suspension, while higher trims are equipped with front multi-link independent suspension. The suspension tuning is soft, delivering exceptional ride comfort.

How to Deal with Black Rubber Scratches on a Car?

Methods to remove black rubber scratches from a car are as follows: 1. Polishing is sufficient. Car polishing is a process in car detailing that involves polishing the car before waxing, sealing, or coating. This is because sealing or coating requires prior polishing, and only a finely polished car can achieve a mirror-like finish. 2. If oxidation is not obvious, generally the paint quality of a new car is good, and it is recommended not to polish when waxing or sealing. When car polishing is necessary, it is essential to go to a professional detailing shop, not only to ensure the quality of the polishing wax but also to minimize damage under the operation of professional technicians.
