Should Transmission Fluid Be Changed During the First Maintenance?

The first maintenance does not require changing the transmission fluid. Below is an introduction about changing transmission fluid during the first maintenance: 1. Generally, it is recommended to change the transmission fluid every 60,000 kilometers. Transmission fluid is a lubricant that keeps the gear system clean, ensuring the normal operation of the transmission and extending the lifespan of the transmission components. 2. Most transmission fluids can be used in automatic transmissions available on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, structure, etc. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors affecting gear shift quality. 3. The fundamental difference lies in their friction systems. HFM-ATF has finer oil molecules and efficient anti-shear capability. In a semi-clutch state or at the moment of engagement, the oil film acting on the surface of the friction material can create a highly effective suspended state, causing slippage to buffer the instant powerful impact, making the engagement smoother and gear shifts more seamless. At the same time, the fine oil molecules significantly reduce valve sticking, making the valve body work more smoothly.

Is the Asian Lion a B-segment car?

Asian Lion is an A-segment sedan. A-segment cars, also known as compact cars, typically have a body length between 4.3 meters to 4.79 meters, a wheelbase ranging from 2.35 meters to 2.79 meters, and engine displacements generally between 1.4 liters to 2.0 liters. Due to their ability to meet various needs of ordinary families, they are widely recognized by consumers and have become mainstream in the automotive market. Generally, cars are classified into A, B, C, and D segments, with standards varying by country. China lacks a unified standard, and since German cars were the first to form joint ventures and capture a certain market share in China, the German classification method is often adopted: 1. Specific classification of cars: According to the German car classification standard, A-segment cars include A0 and A00 segment cars, generally referring to small cars; B-segment cars are mid-size cars; C-segment cars are premium cars; and D-segment cars refer to luxury cars. 2. Classification criteria: The classification is mainly based on parameters such as wheelbase, engine displacement, and weight. The further the letter is in the alphabet, the longer the wheelbase, the larger the displacement and weight, and the higher the luxury level of the car.

Why is the fuel consumption of Emgrand GL so high?

The reasons for the high fuel consumption of Emgrand GL are as follows: 1. Severe engine carbon deposits: Carbon deposits usually form on the fuel injectors, spark plugs, throttle valve, and combustion chamber. When carbon deposits accumulate to a certain extent, issues such as difficulty in ignition, stalling during neutral coasting or gear shifting, weak acceleration, and unstable idle speed (fluctuating high and low) will occur. 2. Use of low-quality fuel: Since low-quality fuel contains more impurities and cannot be fully burned, most of the gasoline is expelled from the vehicle. At the same time, a layer of white or reddish-brown substance forms on the surface of the oxygen sensor, leading to misjudgment of exhaust oxygen content measurement and transmission of incorrect data, ultimately resulting in poor control of the fuel injection ratio. 3. Excessive vehicle load: There are too many miscellaneous items in the vehicle. Some car owners prefer to place unnecessary items in the vehicle, which increases the weight. Some owners also like to fill up the fuel tank, which also adds to the vehicle's weight. The greater the vehicle load, the greater the pressure of the tires on the ground, and the greater the tire friction. 4. Use of high-power electrical equipment in the vehicle: Especially during idling, due to the low engine speed, the electricity generated by the alternator is insufficient. When high-power electrical equipment (such as air conditioning cooling or high-power audio systems) is used in the vehicle, it increases the burden on the engine and battery. Operating the vehicle under high load conditions will also lead to increased fuel consumption.

What is a Dual-Clutch Transmission?

Dual-clutch refers to a dual-clutch transmission (DCT). Simply put, it means two sets of clutches work simultaneously—one manages the odd-numbered gears, while the other controls the even-numbered gears. Below are some key points about dual-clutch transmissions: 1. The dual-clutch transmission originated from motorsports but did not become widespread due to durability and other issues. 2. The advantages of dual-clutch transmissions are evident, such as high transmission efficiency, fast gear shifting, low production costs, compact size, and reduced fuel consumption. 3. Dual-clutch transmissions also have drawbacks, including low-speed jerking and relatively poorer reliability.

Is Car Heat Insulation Film Effective?

Car heat insulation film does have certain effects. Here is the relevant information: 1. Good heat insulation: In the solar spectrum, the main source of heat is infrared rays. High-quality heat insulation films can effectively reflect infrared rays, thereby reducing the temperature inside the car, alleviating the burden on the air conditioning system, and saving fuel. 2. Strong UV blocking capability: Ultraviolet rays not only harm human skin but also accelerate the aging of interior decorations. Premium car films provide sufficient UV isolation. 3. Good explosion-proof performance: This is another reason why car films are also known as safety films. When glass with heat insulation film breaks, the fragments will adhere to the film and not fly out to cause injury.

What are the common car faults?

There are several common faults in cars: 1. Burning oil: Feel the exhaust pipe with your hand, and you may find black and wet oil sludge accumulation, and smell an oil odor. In the absence of oil leakage, the oil level is severely low. The car's exhaust pipe emits blue smoke. 2. Vehicle shaking: It could be due to chassis issues, such as loose structures in the front and rear suspension, steering, or transmission. It might also be tire-related problems, such as significant differences in tire pressure among the four tires or issues with tire dynamic balance. Additionally, problems in any part of the ignition system, intake system, or fuel system can lead to car shaking.
