Why doesn't Toyota use a particulate filter?

Toyota does not use a particulate filter because its vehicles are equipped with naturally aspirated engines and hybrid Atkinson cycle engines, while only turbocharged engines require the installation of a particulate filter. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Principle of the particulate filter: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto a filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then expelled.

Should the Handbrake Be Released When Removing Tires?

Whether to release the handbrake when removing tires depends on the situation. If the tire is being removed on a lift, there is no need to engage the handbrake. However, if a simple jack is used to remove the tire, the handbrake should be engaged. Tires are the only components of a car that come into contact with the ground, and they are crucial for the vehicle's driving stability and safety. About Tires: Tires are rubber products, so they naturally age even when not in use. Before using stored tires, it is necessary to check for cracks and rubber aging. Tire Storage: If stored in a suitable environment with constant temperature and away from light, the aging process of rubber can be significantly slowed down. Using them after several years is not a problem. However, if the storage area is exposed to direct sunlight and has large temperature variations, causing the rubber to age and crack, the tires are no longer suitable for use even if they have never been used. Rubber that has lost its elasticity cannot provide the necessary grip.

How many kilometers can a car tire generally last?

Generally, car tires can last about 80,000 kilometers. If the mileage has reached 80,000 kilometers, it is recommended to replace the tires. If the mileage is lower, for example, only 30,000 to 40,000 kilometers after 6 years, a basic inspection of the tires is necessary. Check if there are obvious cracks on the tire sidewalls. If cracks are present, the tires should be replaced promptly. If the car is only driven at low speeds on city roads, the tires can continue to be used, but not for more than 7 years, as prolonged use can lead to tire aging. Note: Choose the right tires: When replacing tires, it's important to select the appropriate ones. The specifications of the new tires should match those of the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. Replace the valve stem as well: After replacing the tires, the aging cycles of the new tires and valve stems differ. During the lifespan of the new tires, the valve stems may develop issues, which are not easily noticeable. Therefore, it's best to replace the valve stems at the same time as the tires.

Why does the ABS warning light stay on after installation on a motorcycle?

The reason why the ABS warning light stays on after installation on a motorcycle may be due to faults in components such as the wheel speed sensor, ABS wiring, ABS pump, pressure regulating solenoid valve, or the ABS computer. How ABS works: During braking, the ABS quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve on the wheel that begins to lock up to maintain braking force. If the wheel continues to lock up, the normally closed output solenoid valve opens, allowing brake pressure on that wheel to rapidly decrease through a direct connection to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (20% slip rate S), achieving the best braking performance and maximum driving safety. The role of ABS: It maximizes the effectiveness of the brakes, reducing braking time and distance. It effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing excellent steering control. It avoids severe friction between the tires and the ground, reducing tire wear.

Why Do 4S Stores Not Allow Customers to Watch During Maintenance?

The reason why 4S stores do not allow customers to watch during maintenance is that the natural environment during vehicle repair and maintenance is not particularly clean. The maintenance area is where vehicles come and go. If the owner is accidentally hit by a car in the workshop, the responsibility is unclear. Maintenance Environment: If a mechanic accidentally dirties their clothes during maintenance, it would be unpleasant. Owners are not allowed into the workshop to avoid interfering with the maintenance work. It can be said that 4S stores are currently the most reliable in after-sales maintenance, and there will be no tampering with the vehicle during the process, so owners can basically relax and drink tea in the lounge. Of course, there are exceptions. Maintenance Location: For the safety of the owners, 4S stores will not allow them to enter the maintenance area and will direct them to the lounge to rest. The primary reason most 4S stores prohibit owners from entering the maintenance area is for their own safety. 4S stores follow standardized service procedures, which include directing customers to the lounge, reflecting the high-quality service of 4S stores. Owners can also enjoy good rest and entertainment during maintenance and repairs. Additionally, there are many small vehicles inside the workshop, making it a hazardous environment.

What Causes Difficulty in Starting a Motorcycle Carburetor When Cold?

Motorcycle difficulty in starting when cold but normal when warm can be attributed to the following reasons: Poor fuel quality: Often, low-quality fuel has poor volatility, especially in winter when temperatures are low. During cold starts, the engine block temperature is low, making fuel atomization difficult. This affects the proper mixing of fuel injected into the cylinder with air, leading to starting difficulties or even failure to start. Lower temperatures: The colder it is, the more fuel is required for a cold start, and carbon deposits can significantly affect the ease of cold starting. Carbon deposits in various parts of the engine can adversely affect its normal operation. For example, excessive carbon deposits in the combustion chamber can increase the compression ratio, creating multiple hot spots that lead to pre-ignition and knocking, reducing the engine's lifespan. Carbon deposits on the valve and its seat surfaces can cause the valve to close improperly, leading to gas leakage, difficulty in starting the engine, reduced power, and increased susceptibility to valve burning. Spark plug issues: Delayed replacement of spark plugs is another common factor. Cold starts require higher ignition energy, and after a certain mileage, the electrode gap of the spark plug widens. If it exceeds the standard, the spark energy produced will significantly weaken, making it difficult to ignite the air-fuel mixture in the cylinder (commonly known as misfiring), naturally making it very hard to start.
