TPWS on a car stands for Tire Pressure Warning System. When a TPWS fault code appears, it indicates that the tire pressure needs calibration. Vehicles displaying this fault code are equipped with a tire pressure monitoring system, which continuously monitors the tire pressure in real-time and alerts the driver in case of underinflated, overinflated, or leaking tires to ensure driving safety. There are two types of tire pressure monitoring systems: 1. Indirect TPMS, which detects abnormal tire conditions by monitoring the rotational speed difference of the tires; 2. Direct TPMS, which uses four tire pressure sensors installed inside the tires to automatically monitor tire pressure and temperature, whether the car is stationary or in motion, and alerts the driver to high pressure, low pressure, or high temperature conditions to prevent traffic accidents caused by tire failures and ensure driving safety.

What Causes a Motorcycle to Cut Off Fuel at 6000 RPM?

Motorcycle cutting off fuel at 6000 RPM is basically a carburetor issue, such as problems with the carburetor's air-fuel mixture ratio, needle valve, fuel level, choke, etc., or improper adjustments, as well as the carburetor itself being faulty or incompatible with the motorcycle. The focus should be on inspecting and adjusting the carburetor, or replacing it. Motorcycle gradually slowing down and cutting off fuel: If a motorcycle gradually slows down and cuts off fuel while riding, with the engine slowly shutting off on its own and a noticeable loss of engine power before stalling, it is generally a fuel supply system malfunction. Engine cutting off fuel and stalling with noise: If the engine makes a loud "popping" sound during the fuel cutoff and stalling process, cannot be restarted after stalling, and the kickstarter lever feels very little compression, it can be determined that the cylinder head gasket has been burned through or the crankshaft oil seal is damaged.

What does motorcycle CVT mean?

Motorcycle CVT (Continuously Variable Transmission) has no gears and uses an automatic centrifugal clutch. It changes the transmission ratio by adjusting the diameters of the front and rear pulleys. This type of transmission has no fixed steps and is entirely controlled by throttle, engine speed, and pulley diameter changes. Definition of stepped transmission: Automatic disengagement still means the clutch is in an automatic disengaged state, while stepped transmission incorporates gear shifting. This combination significantly improves working efficiency compared to scooter transmission forms, enhancing power while reducing fuel consumption, though it still has drawbacks. Definition of multi-speed transmission: This type of transmission still consists of a clutch and gear shifting, except that the clutch is no longer automatically disengaged but manually disengaged instead.

Does a deformed car tire cause shaking when driving?

A deformed car tire will cause a sensation of up-and-down shaking and vibration when driving. If a car's tire becomes deformed or worn, it must be replaced immediately to prevent affecting the normal use of the vehicle and to ensure driving comfort. Wear Limit: When the tire wears to the wear limit indicator, there are small triangular patterns along the sidewall and the edge of the tread. Moving horizontally from any of these triangles to the tread pattern, you will notice small raised sections within the tread that are lower than the normal tread pattern. These are the safety indicators, and driving beyond this point means the tire should be replaced. Aging Degree: Check the tire's aging degree. If the tire has many cracks but they do not affect normal use, it can still be driven. However, if the crack depth exceeds three millimeters, the tire needs to be replaced. Tread Deformation or Bead Damage: Tires with tread deformation or bead damage, if driven while flat, can cause the sidewall to be crushed and damaged. Tires corroded by chemicals should not be used. Tire Repair: If a tire has been repaired more than three times, it is necessary to replace it with a new one.

Can National VI Diesel Vehicles Operate Without Urea?

National VI diesel vehicles cannot operate without urea. With the country's increasing emphasis on environmental protection, vehicle urea has become an indispensable necessity for National V and VI heavy-duty diesel vehicles. Operating a diesel vehicle without urea not only subjects the owner to hefty fines but also leads to severe consequences that can affect the normal operation of the vehicle. The functions of adding urea to diesel vehicles include: Optimizing Engine Performance: Using urea in vehicles can optimize engine performance and fuel consumption, reducing diesel consumption by up to 6%, significantly lowering costs. Purification Effect: It serves a purification function by reacting with nitrogen oxides in the exhaust, reducing nitrogen oxide emissions. Vehicles are equipped with a dedicated urea tank where the urea is stored. As long as the vehicle is running, urea will be consumed, so it is essential to replenish it promptly.

What Causes the Steering Wheel to Make a Clicking Sound on Bumpy Roads?

Steering wheel noise on bumpy roads may be related to steering system issues such as excessive play in the steering shaft spline, looseness in the steering shaft universal joint, loose steering ball joints, or steering gear malfunctions. It could also be associated with suspension system faults like shock absorbers or their support bearings. Try to steer after the vehicle is in motion: Avoid turning the steering wheel while stationary; try to steer only after the vehicle has begun moving. Stationary steering should only be used occasionally in special circumstances, such as when maneuvering out of a parking space. Straighten the steering wheel after parking: When the vehicle is parked, the steering wheel should be returned to the center position to prevent the suspension system and tires from bearing unnecessary load. Avoid turning the steering wheel to the lock position when making a U-turn: When making a U-turn, try to avoid turning the steering wheel all the way to the lock position.
