What causes the idle vibration of the Jog-I?

Jog-I idle vibration may be caused by the following reasons: Carburetor issue: If the carburetor has not been cleaned for a long time, it may lead to unstable idle speed. Engine air leakage: Slight air leakage in the engine can also cause unstable idle speed in motorcycles. The reasons for air leakage can vary, such as overly tight valve clearance, poor sealing at the connection between the carburetor and the cylinder, or damage to the secondary combustion pipe in China III models, all of which can result in engine air leakage. Ignition system failure: Minor damage to the ignition system. In this case, although the vehicle can still start, it may exhibit unstable idle speed similar to a carburetor malfunction.

What is the purpose of a crash cushion truck?

The purpose of a crash cushion truck: It is parked behind construction zones. If a vehicle fails to notice the construction area and collides from behind, the truck's cushion pad can absorb the impact energy, ensuring the safety of workers ahead. Crash cushion trucks are primarily used in highway construction, tunnel construction, and road construction projects to reduce safety risks for construction vehicles, maintenance personnel, and traffic police handling accidents. The crash cushion energy-absorbing module mainly consists of an onboard cushion pad and a guide sign frame, serving as a buffer guard behind construction vehicles. In the event of a rear-end collision, it creates a buffer zone between the colliding vehicle and the construction area ahead, absorbing impact energy through structural deformation of the equipment, thereby significantly reducing the likelihood of collisions with protected personnel and equipment.

What is the difference between beam wipers and conventional wipers?

The difference between beam wipers and conventional wipers lies in the material and the wiping effect. Material difference: Beam wipers use stainless steel as the connecting material, making them lightweight, easy to install, and quieter during use, but they are slightly more expensive. Conventional wipers are made of iron, which is harder and less prone to deformation during use, but they produce more noise, have a longer lifespan, and are lower in cost. Wiping effect: Beam wipers, without the support of a frame, provide better contact with the windshield and more even pressure and wear distribution, resulting in superior wiping performance. Conventional wipers, supported by a frame, are more effective at removing debris from the windshield, especially larger particles, ensuring efficient impurity removal.

Can a temporary ID card be used for the Subject 4 driving test?

Temporary ID cards can be used for the Subject 4 driving test, as they hold the same legal validity as regular ID cards. Applicants can obtain a temporary ID card on the same day by visiting any public security bureau, submitting their household registration booklet, a recent one-inch black-and-white photo without a hat, and paying the document processing fee. Subject 4 is part of the motor vehicle driver's license examination, which separates the safety and civilized driving requirements from the original Subject 1, including safe driving skills in complex conditions and emergency handling knowledge. It is conducted after the Subject 3 road test to further assess the candidate's traffic awareness and competency.

What are the hazards of parking with wheels not straightened?

The hazards of parking with wheels not straightened: 1. Accelerated aging of the steering tie rod. The tie rod remains under force for a long time and cannot return to its original position, leading to accelerated aging over time; 2. Accelerated aging of the power steering pump. When the hydraulic power steering system's pump pushes oil for steering but lacks a return oil action, it causes negative pressure in the pump, which over time accelerates its aging; 3. The suspension will tilt towards the direction the wheels are not straightened, causing accelerated wear on the soft-support rubber pads and bushings; 4. Increased force on the tire sidewalls leads to accelerated wear, which over time can result in dangerous situations like tire blowouts.
