Is the 'Yaxiang' a Transmission?

Yaxiang (not called 'Yaxiang') is a transmission, just a different term for it. The formal name is transmission, while the industry slang is Yaxiang. Transmissions are categorized into manual transmissions and automatic transmissions, which differ in structure. A manual transmission consists of planetary gears, brakes, and one-way clutches; an automatic transmission is composed of a pump wheel, turbine, and guide wheel. Introduction to Transmissions: A transmission is a device that changes the speed ratio and direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Functions of a Transmission: The primary role of a transmission in a vehicle is to amplify torque, adjust speed, enable reverse motion, and interrupt power. The engine transmits power to the transmission through a clutch plate or hydraulic coupler. After speed adjustment by the transmission, the power is output to the driveshaft, which then transfers the power to the wheels, driving the vehicle forward. This constitutes a complete power transmission process. Whether the transmission is automatic or manual, their transmission paths are the same.

Why does the original car paint peel off?

Peeling of the original car paint occurs when the primer is not completely removed; when the undercoat and primer materials are not polished multiple times, or when the paint quality is poor. Methods to prevent paint peeling: Park the car indoors as much as possible, preferably without a car cover. Regularly check the humidity inside the car. After washing the car, try to drive for a while. For soft paint surfaces, it's best to apply glaze sealing. Precautions for car painting: When performing car body repair and painting, choose an auto repair shop with a good reputation and skilled technicians. Car body repair is crucial; if not done properly, the car's surface will appear uneven, greatly affecting its appearance. Apply putty evenly. During painting, ensure a suitable environment—generally, a professional enclosed paint booth is standard to guarantee paint quality.

Causes of Three-Way Catalytic Converter Failure in Engines?

The causes of three-way catalytic converter failure in engines include overheating of the converter and the use of low-quality leaded gasoline. Causes of Failure: The three-way catalytic converter can only withstand temperatures up to approximately 800 degrees Celsius during operation. Exceeding this temperature can lead to internal decomposition and melting, thereby affecting the converter. The use of low-quality leaded gasoline, oil collisions and undercarriage impacts, as well as the indiscriminate use of various additives, can all cause three-way catalytic converter failure. Solutions for Failure: Avoid prolonged idling, as it raises the internal temperature of the engine, which is already higher than usual. Try not to idle for more than 10 minutes. Do not use leaded gasoline or oil additives, and develop good driving habits. While driving, if symptoms such as surging, stalling, or backfiring occur, take them seriously and stop the vehicle immediately for inspection. Otherwise, it may lead to severe damage to the catalytic converter.

What are the pros and cons of installing an oil catch can on the engine?

The advantage of installing an oil catch can on the engine is that it can reduce the trouble caused by carbon deposits to the car, while the disadvantage is that the oil catch can needs to be cleaned regularly. The function and working principle of the oil catch can are as follows: Function of the oil catch can: The oil catch can uses the negative pressure in the intake manifold to draw blow-by gases formed in the crankcase and direct them back into the combustion chamber for re-burning. These blow-by gases mainly consist of oil vapor and combustible mixed gas. Since oil is viscous, if it directly enters the intake pipes, it may adhere to the walls of the intake pipes, forming carbon deposits that obstruct airflow. Working principle of the oil catch can: The oil catch can can lower engine temperature and increase cylinder durability. Its working principle involves collecting oil vapor, preventing the vapor from undergoing secondary combustion, and reducing the formation of carbon deposits. It primarily serves to protect the engine and can effectively alleviate the issue of oil burning.

Can Dual Hybrid Vehicles Get Green License Plates?

Only certain models of dual hybrid vehicles are eligible for green license plates. The relevant information about green license plates is introduced as follows: Function of Green License Plates: The design of green license plates embodies the concepts of "green, environmental protection, and technology," featuring green as the main color tone, with added special identifiers. They utilize new designs, materials, processes, and anti-counterfeiting technologies, which not only facilitate differentiated management and easy identification but also highlight the characteristics of new energy and technological innovation. Specifically, the background color of small new energy vehicle license plates uses gradient green, while large new energy vehicle license plates use a combination of yellow and green. Process for Obtaining Green License Plates: Open the traffic management bureau website, log in to the local site, select business services, choose the new energy vehicle license plate pre-selection option, enter the pre-selection section to select your vehicle, click the confirmation button below, submit for review and make an appointment, schedule the processing time, return to the business services section, and select the new energy vehicle license plate replacement appointment. Start the appointment, choose the time and vehicle management office for license plate issuance, and go to collect the license plate at the scheduled time.

What Causes the Engine to Stall When the Choke is Opened?

The engine stalling when the choke is opened may be due to issues with carburetor adjustment, where the fuel-to-air ratio is severely imbalanced, leading to insufficient combustion and stalling due to excessive air and insufficient fuel. Choke Construction: There are two types of choke constructions. One is the automatic electric choke, and the other is the manual choke. The manual choke is more intuitive and stable in control, requiring no adjustments. The driver simply feels the length of the cable pulled to adjust the mixture concentration. Choke Function: During cold starts, the choke appropriately closes part of the air intake to increase the gasoline concentration in the mixture entering the cylinder, improving the engine's starting performance. Once the engine is running normally, the choke should be fully opened. Otherwise, an overly rich mixture can cause the engine to malfunction and result in excessive fuel consumption. Fuel-injected engines automatically control this process without manual operation.
