What Causes the Car to Jerk When Braking?

It is normal for a car to jerk when braking hard, as this is the ABS system in action. If the car jerks when not braking hard, it may be due to uneven surfaces on the brake discs. Below is an introduction to ABS: 1. ABS stands for Anti-lock Braking System: ABS is installed to address the issue of wheel lock-up during braking. Its working principle involves a rapid cycle of braking and releasing, but ABS operates much faster than manual control. Cars equipped with ABS can effectively maintain wheel rotation without locking up, significantly improving vehicle stability during braking and braking performance on poor road conditions. 2. Origin: If the wheels lock up, the car may skid and lose control, making it impossible for the driver to steer or slow down the vehicle. Therefore, engineers developed the ABS to prevent wheel lock-up during emergency braking.

How much water in the car fuel tank makes it undrivable?

It is unsafe to drive when there is about 50ml of water in the car fuel tank. The following are precautions for the fuel tank: 1. The basic function of the fuel tank is to store fuel, ensuring the vehicle has a certain driving range. Structurally, it should have devices to prevent fuel sloshing. The number and capacity of fuel tanks vary depending on the vehicle model. Ordinary cars usually have one fuel tank, while long-distance commercial vehicles often have two. 2. Passenger car fuel tanks are usually installed at the rear of the vehicle body, while commercial vehicle fuel tanks are generally installed on the outer side of the middle part of the body. A fuel tank typically consists of the tank body, baffle, fuel filler pipe and cap, and drain plug. The basic requirement for fuel tank maintenance is regular inspection and cleaning.

Why does the engine stall when idling normally but accelerating hard?

There are two situations when the engine idles normally but stalls when accelerating hard: 1. The first situation: The engine stalls due to an overly rich air-fuel mixture in the engine. An overly rich air-fuel mixture means excessive fuel injection in the engine. Common causes for an overly rich mixture may include a faulty oxygen sensor or inaccurate air intake measurement. In this case, the motorcycle stalls, usually due to ignition system failure or fuel system issues. 2. The second situation: The engine stalls due to an overly lean air-fuel mixture in the engine. An overly lean mixture means insufficient fuel injection in the engine. Contrary to the above situation, if the needle seat and emulsion tube fall into the fuel bowl, the needle won't be lifted as the plunger rises, thus failing to provide enough gasoline, making the mixture even leaner. This can likely result in the inability to ignite the mixture.

What should be noted for a self-driving trip?

Here are the precautions for a self-driving trip: 1. Maintain a good driving condition: Long-distance drivers must maintain good physical and mental condition, ensuring sufficient sleep before driving. 2. Wear seat belts: Not only the driver and front-seat passengers, but also rear-seat passengers need to fasten their seat belts. If there are children under the age of twelve in the family, it is recommended to purchase child safety seats produced by reputable manufacturers. 3. Driving in rain or snow: Turn on the fog lights and width indicator lights. Drive slowly, avoid overtaking casually in bad weather, lightly press the accelerator, gently apply the brakes, and steer slowly. When overtaking, use the horn and headlights to signal, and only overtake after the vehicle in front has given way. Be extra cautious in dark and damp areas such as under overpasses and tunnel entrances, as they are prone to icing, and reduce speed accordingly.
