Car jerking sensation is related to two major components: the engine and the clutch. There are many factors that may cause jerking during car startup and low-speed acceleration, such as engine oil passage blockage, insufficient or deteriorated transmission oil, unskilled operation of clutch and throttle coordination, or releasing the clutch too quickly during startup. The following are relevant introductions about jerking sensation: 1. Related to the engine: If the car has a jerking sensation while driving, the engine is definitely involved. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the air intake volume decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, resulting in a jerking sensation. 2. Normal situation: Jerking during the startup of an automatic transmission car is normal, because except for CVT continuously variable transmission, other transmissions will have a jerking sensation.

What is the role of seat belts when a vehicle collides?

When a vehicle collides, the role of the seat belt is to reduce the likelihood of death or serious injury in a traffic collision by minimizing the secondary impact force that poses an internal collision risk. It ensures the occupant is properly positioned to maximize the effectiveness of the airbag and prevents the occupant from being ejected from the vehicle or experiencing rollover during a collision. A seat belt is a vehicle safety device designed to protect occupants from harmful movements caused by collisions or sudden stops. The correct way to use a seat belt is: 1. First, adjust the height of the seat belt. If it is too high, it may tighten around the neck during an emergency, and if it is too low, it may not fully restrain the body from moving forward. 2. After fastening the seat belt, it should not be too loose or too tight—approximately leaving room for two fingers—to ensure safety without causing discomfort.

Can I Pick Up the Car on the Same Day I Pay for It?

Generally not. After receiving the payment, the 4S dealership needs to issue an invoice, arrange insurance, apply for a temporary license plate, clean the vehicle, and prepare for the handover ceremony. It's difficult to complete all these tasks on the same day. Therefore, to ensure everything is properly prepared, 4S dealerships usually deliver the new car the next day, completing all procedures and thoroughly cleaning and inspecting the vehicle the day before to confidently hand it over to the customer. Here are some precautions for picking up the car: Production Date: Cars produced within the last three months are considered new. If the production date exceeds three months, they are considered stock vehicles. Be cautious of purchasing stock vehicles. Check Vehicle Documentation: Ensure all documents are complete, including the vehicle certificate of conformity, three-service warranty card, vehicle user manual, and other necessary documents.

Does the fuel from small gas stations affect the engine?

The gasoline from small gas stations may be cheaper, but the quality is less guaranteed. Poor-quality gasoline contains more impurities, leading to abnormal combustion, which can damage the engine. It is not recommended to refuel at non-standard gas stations. Below is detailed information about standard gas stations: 1. Overview: A gas station is a retail facility that provides gasoline and oil for vehicles and other motor vehicles, typically supplying fuel oil, lubricants, etc. Due to the flammable, explosive, volatile, leak-prone, and static-prone nature of petroleum products sold at gas stations, safety is the top priority. 2. Precautions: Open flames are strictly prohibited at gas stations, as are any activities that may generate sparks. It is forbidden to add gasoline to a car's carburetor or oil drum. All vehicles must turn off their engines before refueling, and hazardous materials are strictly prohibited on the premises.

How long is the lifespan of an engine after water ingress repair?

After repair, the lifespan is only about 60-70% of the original. The engine is a relatively precise machine. If water enters during high-speed operation, it can damage the combustion chamber and spark plugs inside. Below is a detailed introduction to the symptoms of engine water ingress: 1. Stalling while driving: Due to water entering the engine filter element, the intake resistance increases and water enters the combustion chamber, preventing the spark plugs from igniting. Water entering the distributor causes it to lose its normal ignition function. 2. Overheating of the breather pipe: In summer, this can damage lubrication, causing overheating, and hot air escapes from the crankcase breather pipe. This indicates that the engine has water ingress. 3. Brake failure: Rain increases air humidity. If water enters the brake fluid, it vaporizes under high temperatures, leading to brake failure or complete loss of function.
