The main reason why the wiper does not work in the first gear is a faulty wiper relay. The following are the related causes and solutions: 1. Relay failure: The wiper relay has high and low gears. If the low gear is damaged while the high gear is normal, the wiper will not move in the slow gear but will work in the fast gear. Solution: Replace the relay to solve the problem. 2. Fuse damage: A damaged fuse can prevent car components from working properly, which may affect the operation of the wiper. In this case, it is necessary to check whether the wiper fuse is intact. The fuse is mostly located under the left A-pillar of the steering wheel, and it can be seen after opening the fuse box. Solution: Check and replace the damaged fuse.

What are the regulations for speed bumps on urban roads?

According to national transportation technical standards, traffic facilities applied to roads, including speed bumps, must be manufactured to specific specifications. The regulations stipulate that the long side of a speed bump should be 250~500mm, the wide side 200~400mm, and the height 3~10mm. The height of speed bumps is particularly critical, as excessively high speed bumps may cause traffic accidents when vehicles pass at high speeds. The purpose of speed bumps: Speed bumps alert drivers to reduce their speed, especially in harsh environments such as mining sites where heavy vehicles are the primary traffic and flow is high. The quality of speed bumps: Under such conditions, the quality and material of speed bumps are undoubtedly paramount, but their specifications also play a significant role. Speed bumps of different specifications exhibit noticeably different capabilities in withstanding pressure and impact.

What Causes a Loose Steering Wheel?

The reasons for a loose steering wheel are: 1. Damage to the outer steering gear or an over-tightened free gap adjustment bolt of the steering gear; 2. Incorrect camber or toe-in; 3. Worn suspension bushings, causing severe wear on the inner side of the tires. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. Precautions for using the steering wheel include: 1. Do not turn the steering wheel too forcefully or make sudden movements; avoid turning the steering wheel when the vehicle is stationary; 2. When driving on rough roads, hold the steering wheel firmly with both hands to prevent loss of control and potential accidents; 3. Reduce speed when turning; 4. Gradually turn the steering wheel according to the curvature of the bend when entering a curve.

What is the charging method for a motorcycle charger?

The charging method for a motorcycle charger is: 1. Inspect the battery to understand its condition; 2. Connect the positive and negative terminals of the regulated power supply to the corresponding terminals on the battery, remove the cap plugs from the battery, and then turn on the power supply. Motorcycle batteries cannot be charged using car battery chargers, as using a high-power charger may deplete the battery fluid and even cause explosions or fires. Methods to start a motorcycle with a dead battery include: 1. Using the kick starter to start the motorcycle; 2. Engaging the clutch in third gear, pushing the motorcycle to gain speed, then releasing the clutch to start the engine; 3. Charging the battery or replacing it before starting. A motorcycle is a two or three-wheeled vehicle powered by a gasoline engine, steered by handlebars that control the front wheel. It is lightweight, agile, and fast, widely used for patrols, passenger and cargo transport, and also serves as sports equipment. The motorcycle consists of an engine, transmission system, running gear, braking system, and electrical instrumentation. The transmission system of a motorcycle is composed of primary reduction, clutch, gearbox, and secondary reduction.

What causes the vibration of the Lynk & Co 03 three-cylinder engine in the later stage?

The reasons for the vibration of the Lynk & Co 03 three-cylinder engine in the later stage are: 1. The spark plug is damaged, and the gap wear of the spark plug pole leads to insufficient spark plug ignition, resulting in incomplete combustion of the mixture; 2. Poor quality of gasoline leads to poor atomization effect of the fuel injector, and the mixture does not burn completely in the cylinder; 3. The throttle is too dirty, and the fuel injector has excessive carbon deposits; 4. The fuel pump supply pressure is abnormal, or the intake pressure sensor value is incorrect and the operation is poor. Taking the 2021 Lynk & Co 03 as an example, it belongs to a compact car with a body size of 4639mm in length, 1840mm in width, 1472mm in height, a wheelbase of 2730mm, and a curb weight of 1395kg. The 2021 Lynk & Co 03 has a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.5T turbocharged engine with a maximum horsepower of 156PS, a maximum power of 115kW, a maximum torque of 245Nm, and is matched with a 6-speed manual transmission.

What are the reasons why a diesel engine cannot accelerate when stepping on the throttle?

The reasons why a diesel engine cannot accelerate when stepping on the throttle are: 1. Excessive carbon deposits in the vehicle; 2. Poor fuel quality; 3. Blockage in the intake or exhaust system; 4. Aging spark plugs; 5. Cylinder misfire; 6. Insufficient tire pressure; 7. Insufficient engine power; 8. Problems with the combustion chamber, ignition system, or valves. The solutions for a diesel engine not accelerating when stepping on the throttle are: 1. Clean carbon deposits; 2. Use standard gasoline; 3. Replace spark plugs. Maintenance for diesel engines: 1. Break-in: This is the foundation for extending service life; 2. Clean fuel, clean water, clean air, and clean engine body. Diesel and gasoline: These are the main fuels for the engine. If diesel or gasoline is not clean, it can cause wear on the precision components, increase the clearance, leading to oil leaks, dripping oil, reduced fuel supply pressure, increased clearance, blocked fuel lines, and bearing seizure faults; 3. Regularly check and tighten fasteners: Due to vibration, impact, and uneven load during the use of diesel and gasoline engines, bolts and nuts are prone to loosening. Adjustment bolts in all parts should be checked.
