What does it mean when the car displays a tire abnormality?

1 Answers

Tire pressure abnormalities are divided into two situations: excessive tire pressure or insufficient tire pressure. Detailed explanations are as follows: 1. Insufficient tire pressure: This increases tire body deformation, enlarges the contact area with the ground, accelerates shoulder wear, and makes the tire sidewalls prone to cracking. It also causes flexing motion (increased friction), leading to excessive heat generation, increased fuel consumption, accelerated rubber aging, fatigue of the cord layers, cord breakage, and the risk of tire blowouts. 2. Excessive tire pressure: This reduces the contact area with the ground, causes severe wear in the center of the tire, decreases traction, and makes the car more prone to accidents. 3. Tire pressure: The internal pressure of a car tire is significant, and this pressure is referred to as the tire pressure. Often likened to the car's 'blood pressure,' tire pressure plays a crucial role in the vehicle's operation.

What is the method of pressing the clutch before braking?

The method of pressing the clutch before braking: If you encounter a red light at an intersection and need to stop, or when pulling over to the side, you should first press the clutch. When approaching the crosswalk, directly apply the brakes. This is because the lower the car's speed, the greater the frictional resistance between the tires and the ground. If you brake first, the engine is more likely to stall. The minimum speed for each gear is the speed when the engine is idling. When the speed in a certain gear is lower than this threshold, the engine is prone to stalling. When decelerating, as long as the current speed is higher than the idle speed of the current gear, there is no need to press the clutch. When braking in the current gear, as long as the engine speed does not drop below idle, there is no need to press the clutch.

Differences Between Plug-in Hybrid and Hybrid Vehicles?

Below are the differences between plug-in hybrid and hybrid vehicles: 1. Charging Requirement: Hybrid electric vehicles do not require charging; they simply maximize the advantages of both the electric motor and the internal combustion engine to achieve fuel efficiency. Plug-in hybrid vehicles, on the other hand, require charging and can be used as pure electric vehicles for short-distance driving, thus consuming no fuel. 2. Energy Recovery Mode: Plug-in hybrid vehicles also feature an energy recovery mode, where under specific conditions, the vehicle can use fuel consumption to regenerate electrical energy. However, while plug-in hybrids have stronger battery storage capabilities, this also means they need to be charged and cannot be driven at any time, making them slightly more inconvenient to use.

How to Determine the Distance Between the Car Front and a Wall

Because after the rearview mirror aligns with the base of the wall, the distance between the car front and the wall is approximately only fifty centimeters. Below are the distances when different parts of the car front come into contact with the vehicle body: 1. Front Wheel Tires: When the edge of the car front just "touches" the lower edge of the front vehicle's tires, the distance between the car front and the front vehicle is about 5 meters. 2. Above the Front Bumper: When the car front aligns with the lower part of the front vehicle's bumper, the distance between the car front and the front vehicle is about 3 meters. 3. Below the Front Bumper: When the car front aligns with the upper part of the front vehicle's bumper, the distance between the car front and the front vehicle is 1 meter.

What Are the Determining Factors of Engine Displacement?

Engine displacement is determined by the size of the engine cylinders and the number of cylinders. Below are the relevant explanations: 1. Definition of Displacement: Displacement (Swept-volume), a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or expelled per stroke or cycle. Generally, a larger displacement means the engine releases more energy (converting chemical energy of fuel into mechanical energy) per unit time, resulting in better "power performance." Therefore, off-road vehicles and sports cars typically have relatively larger displacements. The working volume through which the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is usually expressed in liters (L). 2. Importance of Displacement: Engine displacement is one of the most important structural parameters, representing the size of the engine more accurately than cylinder diameter and number of cylinders. Many performance indicators of the engine are closely related to displacement.

Is a 30-centimeter distance mandatory for right-angle turns?

A distance of 20-30 centimeters from the edge line should be maintained during right-angle turns. The right-angle turn is part of the second subject in the driver's license examination. Subject 2, also known as the small road test, is a segment of the motor vehicle driver's license assessment, specifically referring to the field driving skills test. The test includes five mandatory items: reversing into a parking space, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving. Below are some techniques for right-angle turns: 1. Park the vehicle at the starting position for the right-angle turn, shift into first gear, release the handbrake, slowly lift the clutch while maintaining a semi-linked state, and begin moving at a steady speed, keeping the vehicle 20 centimeters away from the left edge line of the road; 2. Adjust the 20-centimeter gap yourself and maintain a steady speed, then observe a point slightly ahead of the middle door lock on the right (left) side of the vehicle. Once the right (left) front edge yellow line of the road reaches this point, stop immediately and turn the steering wheel fully to the right (left); 3. After turning the wheel fully, start the car and proceed slowly at a semi-linked steady speed through the turn. When you feel the car is about to straighten out, gradually return the steering wheel to the center position, then turn it back to straighten the vehicle, and stop the car straight.
