Engine oil emulsification is caused by water mixing into the oil. The specific reasons and solutions are as follows: The causes of water entering the engine oil are: 1. Cracked water cavity in the heat exchanger leading to water leakage into the oil. 2. Poor sealing of the cylinder head or cracked water cavity, loose sealing of the cylinder liner water jacket, cylinder liner cavitation, allowing water from the combustion chamber to enter the oil. Emulsified oil will have reduced oil film strength, failing to meet the lubrication requirements of the engine, and thus needs to be replaced. The solutions for engine oil emulsification are: 1. Clean the engine and replace the oil. 2. Clean the air filter chamber, exhaust pipe, carburetor, and exhaust joint. 3. Fill the engine with kerosene, repeatedly start and shut off the engine, ensuring the burning time does not exceed 30 seconds, then replace with new kerosene.

How to Fold the Rearview Mirror of the Buick Excelle?

The Buick Excelle only equips the automatic folding function for rearview mirrors in its top-tier Internet Flagship model. To fold the mirrors, press the mirror adjustment button downward. Here is some relevant information: 1. For other models without electric folding functionality, lift the mirror slightly upwards first, then push it firmly toward the door to fold it. When parking by the roadside, it's advisable to fold the mirror on the roadside side to prevent it from being hit by passersby. 2. The side rearview mirrors, located on the left and right exterior of the vehicle, are an important safety feature. They come in two types: manual adjustment and automatic adjustment. Most models on the market today are equipped with electrically adjustable exterior rearview mirrors. Additionally, features such as electric folding, mirror memory, mirror heating, automatic tilt-down in reverse, automatic folding upon locking, and automatic anti-glare are also available.

What material is the Volvo S90 body made of?

Volvo S90 body is made of high-strength steel and some aluminum materials. The main properties of steel plates include: plasticity, elasticity, work hardening, etc. Hot-rolled mild steel plate: generally contains less than 0.15% carbon, with low hardness and low tensile strength. Mainly used for fenders, floors, trunk hinges, bumpers, etc. Below is relevant information about the use of steel and aluminum in automobiles: Application of steel in automobiles: 1. Used for body outer panels, component housings, roof panels, trunk lids, engine hoods, door inner and outer panels, bumpers, fenders, etc. High-strength steel plate: has very high tensile strength and strong resistance to damage. 2. Used for body outer panels, fenders, etc. Surface-treated steel: galvanized steel plates, zinc powder painted steel plates, etc., with good corrosion resistance. 3. Used for doors, roofs, inner panels, lower guards, body bottoms, etc. Application of aluminum in automobiles: 1. The main aluminum materials used in automobiles are aluminum sheets, extrusions, cast aluminum, and forged aluminum. Aluminum sheets were initially used for body engine hood outer panels, front fenders, and roof panels, and later for doors and trunk lids. 2. Other applications include body structures, space frames, outer coverings, and wheel components, such as bodies, air conditioning equipment, engine blocks, cylinder heads, suspension brackets, seats, etc. 3. In addition, aluminum alloys are widely used in automotive electrical components and wiring, and aluminum-based composites can also be used for brake pads and some high-performance structural components.

What transmission is used in the Bestune T77?

The transmission of the Bestune T77 is independently developed by China FAW Group and Bestune. China FAW Group Corporation (abbreviated as FAW Group, China FAW, or FAW, with the English name FAW) is located in Lvyuan District, Changchun City, Jilin Province, China, and was formerly known as the First Automobile Works. The Bestune T77 transmission adopts a 5-speed manual or 7-speed dual-clutch transmission. The 7-speed dual-clutch transmission refers to a dual-clutch transmission with 7 forward gears, also known as a 7-speed dual-clutch transmission, which uses a wet clutch. The dual-clutch, or dual-clutch transmission (DCT), is different from the general automatic transmission system. When using the Bestune T77 transmission daily, the following points should be noted: Do not delay changing the transmission oil for too long. Although many models now have maintenance-free transmission oil, maintenance-free does not mean no replacement. Prolonged failure to change the transmission oil can lead to damage to bearings, casings, and other components inside the transmission. Avoid prolonged coasting in neutral. When driving a manual transmission model, many "experienced drivers" may coast in neutral, but for automatic transmission models, coasting in neutral can cause the automatic transmission to overheat, and there will be a certain impact when shifting back into D gear. Never shift into D/R gear before the vehicle comes to a complete stop. Many drivers, in order to demonstrate their "smooth" operation, will directly shift into reverse gear before the vehicle stops completely, which can cause significant damage to the gears inside the transmission. Over time, this can lead to gear grinding and other faults. Do not frequently climb steep slopes in D gear. When facing some steep slope sections, automatic transmission vehicles often overheat due to high load or shift up too early, resulting in insufficient climbing power. In this case, the manual mode can be used to limit low-speed gears or the sport mode to protect the transmission. Do not tow over long distances. When an automatic transmission vehicle breaks down, a flatbed tow truck should be used to move the vehicle onto the tow platform while it is in N gear, rather than using a tow rope or directly towing the vehicle.

What are the causes and solutions for car air conditioning not cooling?

Here are the causes and solutions for car air conditioning not cooling: 1. The air conditioning compressor belt is too loose. If you turn on the air conditioning in the car and hear a "squeaking" sound, you should pay attention - the likely cause of poor cooling is a loose compressor belt. In this case, the compressor belt needs to be tightened. Additionally, since these belts are made of rubber, they have a limited lifespan. If the belt has aged and become unusable, it needs to be replaced. 2. Insufficient refrigerant. The common refrigerant code is R134A. Insufficient refrigerant affects the cooling performance of the air conditioning system, resulting in inadequate cooling. Generally, the refrigerant operates in a relatively closed environment. However, after prolonged use of the vehicle, components in the air conditioning system may age or wear out, potentially causing refrigerant leaks and insufficient refrigerant levels.
