Is 14 liters per 100 kilometers high?

14 liters means a fuel consumption of 14L per 100 kilometers. Whether this is high is relative. For example, it is considered high for small sedans with an engine displacement of around 1.6-2.0L, but it is normal for large-displacement vehicles, such as large SUVs. Ways to reduce fuel consumption: 1. Correctly adjust tire inflation pressure: Proper tire pressure can reduce rolling resistance and lower fuel consumption. Additionally, slightly higher tire pressure (about +0.2bar above the recommended value) can also save fuel. 2. Use in-car auxiliary electrical equipment moderately: Some electrical devices significantly increase fuel consumption, such as the air conditioning system's cooling function. If the heating purpose has been achieved, the seat heater should be turned off promptly. The rear window heater should also be turned off when there is no fog or ice. 3. Use gears correctly: Match the gear to the speed; avoid high speed with low gear or low speed with high gear. Shift gears in advance, ensuring the gear matches the appropriate speed, and avoid driving at high speeds with low gears or low speeds with high gears.

What do S and H represent in shock absorbers?

Shock absorbers generally have two adjustment directions: hard and soft. H stands for hard, and S stands for soft. Below is relevant information about shock absorbers: 1. Function: Shock absorbers (Absorber) are mainly used to suppress the oscillation of the spring after absorbing shocks and the impact from the road surface. When driving on uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself still has reciprocating motion, and the shock absorber is used to suppress this spring bounce. If the shock absorber is too soft, the car body will bounce up and down. If the shock absorber is too hard, it will create excessive resistance, hindering the normal operation of the spring. 2. Matching: In the process of modifying the suspension system, hard shock absorbers should be paired with hard springs, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. The device connected to the vibration-damping crankshaft is used to counteract the torsional vibration of the crankshaft (i.e., the phenomenon where the crankshaft twists under the impact force of cylinder ignition).

How many points are deducted for making a U-turn and driving in the wrong direction on the road?

Making a U-turn and driving in the wrong direction on the road will result in a deduction of 3 points. Driving in the wrong direction refers to motor vehicles or non-motor vehicles driving on the left side, which is considered as driving in the wrong direction. Circumstances where U-turns are prohibited are as follows: U-turns are prohibited where there are "No U-turn" signs or "No Left Turn" signs: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. The action of making a U-turn is an extension of a left turn, so if there is a sign prohibiting left turns at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If at an intersection where U-turns are permitted, you must cross the crosswalk before making a U-turn and must not make a U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, if there is no sign allowing left turns, U-turns are not permitted. U-turns are prohibited within the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any directional signs, vehicles can only make U-turns from the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make a U-turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and a deduction of 12 points. If you miss an exit on the highway, continue driving to the next exit and leave the highway. Do not attempt an illegal U-turn. Precautions for making U-turns: When making a U-turn, you should turn on the left turn signal in advance, and the maximum speed should not exceed 30 kilometers per hour. Do not hinder other vehicles and pedestrians driving normally.

How often should a white car be waxed?

White cars should be waxed after six months. Here are the relevant details: 1. Protective wax: New cars come with factory-applied protective wax, so waxing is unnecessary for the first six months. Waxing too early may actually remove the original protective wax on the car's surface, leading to unnecessary waste. 2. Color selection: Light-colored car paint can use silver, white, or pearl-colored waxes. For white cars, ordinary pearl-colored or metallic paint waxes are best, while UV-protective wax is recommended in summer. 3. Purpose of waxing: Waxing is a traditional car care practice that helps protect the car's paint.

Do Japanese drive on the left or right side?

Japan's driver's seat is on the right, so Japanese cars drive on the left side of the road, while in China, the driver's seat is on the left, so Chinese cars drive on the right. The direction of the driver's seat is determined by the country's traffic regulations. Here is the relevant content introduction: The traffic roads in China and Japan are different: Japan's traffic roads are left-hand drive, with the driver sitting on the left, which is more conducive to seeing the road conditions when turning right. In contrast, China's traffic roads are right-hand drive, which is beneficial for seeing the road conditions when turning left.

Why is the throttle response slow?

Reasons for slow throttle response: 1. Poor air-fuel mixture, mainly caused by insufficient fuel pump pressure, clogged fuel filter, clogged or stuck fuel injectors, dirty air filter, clogged exhaust pipe or catalytic converter, engine control system issues, etc. 2. Poor or inaccurate ignition, mainly caused by spark plugs, ignition coils, ignition timing, and other engine control system components. 3. Insufficient cylinder pressure, which is a mechanical failure. Mainly related to the transmission, such as transmission slippage, gear damage affecting gear ratio, etc., leading to reduced power transmission efficiency.
