The basic principle of a car's braking system is that when the driver presses the brake pedal, pressure is applied to the brake fluid in the master cylinder. The fluid then transmits this pressure through the pipelines to the pistons in the brake calipers at each wheel. The pistons drive the brake calipers to clamp the brake discs, generating significant friction to slow down the vehicle. The following are the functions of the braking system: 1. Service Brake: During driving, the service brake (foot brake) is commonly used to decelerate the car or bring it to a stop within the shortest distance possible; it also helps maintain a stable speed when driving downhill. 2. Parking Brake: The parking brake not only keeps the car stationary but can also be used in case the service brake fails. Once the car is parked, the parking brake (hand brake) should be applied to prevent the vehicle from sliding forward or rolling backward.

Can Automatic Transmission Cars Stall?

Automatic transmission cars can stall. Whether a car stalls is unrelated to whether it's automatic or manual transmission. Stalling occurs due to faults in the engine's fuel system or electrical system - sudden stalling is caused by electrical issues, while gradual stalling is due to fuel system problems. Automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission automatically selects the appropriate gear based on engine speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations. Introduction to the gears in automatic transmission cars: 1. P stands for Parking gear, used when parking; 2. R stands for Reverse gear, used when reversing; 3. N stands for Neutral gear, used when starting the engine; 4. D stands for Drive gear, used when the car is moving forward; 5. L stands for Low gear, mostly used for climbing or descending hills; 6. S is equivalent to 2nd gear, only shifting between 1st and 2nd gears.

Where is the engine number of the Hongqi H5 located?

The engine number of the Hongqi H5 is located in the front middle-lower part of the engine, above the starter motor, at the junction of the cylinder block and the transmission. The engine number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to represent information such as the manufacturer, specifications, performance, features, craftsmanship, purpose, and production batch of the engine. The Hongqi H5 is a new model launched by Hongqi, which largely continues the design of the Hongqi B-Concept concept car. It features an inverted trapezoidal front grille connected to the headlights, with embedded vertical chrome trim strips.

What is the body weight of the Hongqi H5?

The body weight of the Hongqi H5 is 1578kg. The body weight refers to the vehicle's own weight. Since the body is affected by gravity, all the vehicle's performance will be influenced. If the car is too heavy, its speed cannot perform normally; if the car is too light, the sense of stability decreases. The body refers to the part of the vehicle used for carrying passengers and goods, and it can also refer to the entire vehicle. In some vehicles, the body serves as both the driver's workplace and the space for passengers and cargo. In terms of appearance, the front of this car features a large-sized vertical waterfall-style grille, with sharp headlights on both sides. The emblem on the front face appears more domineering and fierce while maintaining a sense of stability. The side body design is compact, with perfect proportions.

What gear should you use when waiting at a traffic light?

When waiting at a traffic light, an automatic transmission car should be put in N (Neutral) gear; a manual transmission car should be in neutral gear. Depending on the type of vehicle, car gears are divided into automatic and manual transmissions. Gear shifting refers to the transmission, which is used to change the torque and speed of the engine crankshaft to meet the different requirements of driving force and speed for the driving wheels under various road conditions, such as starting, accelerating, driving, and overcoming obstacles. Automatic transmission gears include: P (Park) gear for parking and starting; R (Reverse) gear for reversing; N (Neutral) gear; D (Drive) gear for forward movement, also known as the driving gear; S (Sport) mode; and L (Low) gear for low-speed driving. Manual transmission gears include: first gear, second gear, third gear, fourth gear, fifth gear, and reverse gear.
