Transmission control mechanism's positioning and locking devices include self-locking devices and interlocking devices. Self-locking device: Most transmission self-locking devices consist of self-locking steel balls and springs. The function of the self-locking device is to prevent the vehicle from automatically generating axial movement during bumps, which could cause automatic gear engagement or disengagement. Interlocking device: The interlocking device adds elements such as balls, pins, sliders, or frame plates between shift fork shafts to prevent simultaneous movement of two shift forks and automatic transmission mis-shifting. When one shift fork shaft is moved axially, other shift fork shafts are locked, thereby preventing the transmission from engaging two or more gears simultaneously.

Is Car Color Change Film Illegal?

Applying color change film to a car is legal. Here is an introduction to car color change regulations: 1. There are relevant requirements: if the color change exceeds 30% of the car body, it is necessary to go to the vehicle management office to change the motor vehicle driving license, and it will not affect subsequent vehicle inspections. However, not all color combinations are allowed. The color change cannot imitate police cars, taxis, fire and ambulance vehicles, or use chrome-plated film styles. Additionally, the color change cannot exceed three colors. 2. Documents required for car color change: (1) Original and photocopy of the ID card of the vehicle owner. (2) Original "Motor Vehicle Registration Certificate". (3) Original "Motor Vehicle Driving License". 3. When handling the color change procedure, the handler needs to bring the original and photocopy of the vehicle owner's ID card, motor vehicle registration certificate, motor vehicle driving license, and other documents. If it is handled by an entrusted agent, the original and photocopy of the agent's ID card should also be submitted.

How to Define China 5 and China 6 Emission Standards?

The methods to define China 5 and China 6 emission standards are as follows: 1. The carbon monoxide emission limit for China 5 is 1000mg per kilometer, while for China 6 it's 700mg per kilometer. 2. The sulfur content limit for China 5 is 10ppm with manganese content limited to 2mg per liter, whereas China 6 has a sulfur content limit of 5ppm and manganese content limited to 1mg per liter. 3. During China 5 phase, diesel and gasoline vehicles had different emission standards. China 6 adopts a fuel-neutral principle where emission limits remain the same regardless of fuel type. Additional Information: Methods to identify China 5 and China 6 vehicles: 1. Check the vehicle's manufacturing certificate. 2. Refer to the vehicle's environmental standard list. 3. Examine the vehicle's conformity certificate.

What aspects should be maintained after a new car has traveled 40,000 kilometers?

Here are the aspects that need to be maintained after a new car has traveled 40,000 kilometers: 1. Replace the engine oil, oil filter, and air filter. 2. Replace the coolant, brake fluid, and fuel filter. 3. Automatic transmission cars also require transmission fluid replacement: During the break-in period, metal shavings may accumulate in the fluid. Timely replacement can improve transmission performance. 4. Rear-wheel-drive cars also need differential oil replacement. 5. Replace the power steering fluid to prevent the steering wheel from becoming too heavy. 6. Replace the spark plugs: Spark plugs directly affect whether the engine can start. 7. Replace the brake pads: After 40,000 kilometers, brake pads typically show significant wear. 8. Replace the tires: Prolonged driving may cause certain damage to the tires.

Is coasting in neutral gear harmful to an automatic transmission car?

Coasting in neutral gear can damage the transmission of an automatic transmission car. Additional information: 1. When an automatic transmission car is shifted into neutral gear while driving, the oil pump in the automatic transmission cannot supply oil normally for lubrication, which will cause the temperature of internal components to rise and lead to complete damage. 2. Coasting in neutral gear refers to the operation method where the driver places the gear lever in the neutral position while the vehicle is moving, separating the clutch between the engine and the drive wheels, and using the vehicle's inertia to move. Coasting in neutral must be performed under the condition of ensuring safety and normal vehicle technical condition. It is not allowed to coast with the engine off, especially when going down steep or long slopes, coasting with the engine off or in neutral gear is prohibited.

What does EV mean on a car?

EV button actually refers to the pure electric driving mode. Here is relevant information: Introduction: A mode driven by electric motor, which is not available in conventional power vehicles (conventional power refers to gasoline or diesel vehicles). EV mode is usually equipped in pure electric vehicles or hybrid vehicles. EV button: When using hybrid models, the EV button can serve as an auxiliary mode rather than the main driving mode. When using EV mode, the fuel engine in hybrid models will not start, thus unable to charge the battery, resulting in lower range in EV mode.

Can All Cars Use Full Synthetic Oil?

Not all vehicles are suitable for full synthetic oil. Below is relevant information about synthetic oil: 1. To obtain higher-performance motor oil, humans have chemically synthesized various oils, known as chemically synthesized oil or simply synthetic oil. 2. Synthetic oil is an artificially manufactured lubricant. During production, various natural substances undergo chemical decomposition and are then synthesized with other materials before finally producing synthetic oil. 3. Synthetic oil manufacturers produce different types of synthetic oils based on user requirements. Depending on the intended use, the composition of synthetic oil can be adjusted. 4. The advantages of synthetic oil include superior quality, which manifests in noticeable improvements in the following aspects: smoother cold starts, particularly evident in northeastern regions; better fuel efficiency; extended oil change intervals, approximately 1.5 times longer or more compared to conventional lubricants; prolonged engine lifespan with reduced maintenance needs; and cleaner engine cylinders due to synthetic oil's excellent detergency. 5. In industries such as automobiles and motorcycles, racing cars were the first to adopt synthetic oil, as they predominantly use synthetic oil instead of mineral oil. While synthetic oil performs exceptionally well, it can also be used in regular vehicles. Its main drawbacks are higher manufacturing costs and elevated prices compared to conventional oil. With increasingly stringent vehicle emission requirements, synthetic oil must also take measures to avoid environmental pollution.
