How much fuel can a 50-liter fuel tank actually hold?

A 50-liter fuel tank can actually hold 53 to 55 liters of gasoline. Below are the specific details about automotive fuel tank capacity: 1. Marked volume is the safe capacity: Most fuel tanks indicate a marked volume, which is generally about 10% less than the actual capacity. During the design of the fuel tank, considering the thermal expansion and contraction characteristics of fuel, a certain amount of space must be left in the tank after filling to the rated volume to ensure driving safety and prevent excessive internal pressure. Overfilling can damage the carbon canister, while underfilling leaves too much empty space in the tank, causing fuel to evaporate and be lost as vapor. Therefore, it is sufficient to fill until the pump automatically stops. 2. Fuel gauge cannot accurately reflect the remaining fuel: The fuel gauge on the dashboard cannot be solely relied upon to determine the exact amount of fuel left, as it only provides a qualitative indication rather than a quantitative measurement of the remaining fuel in the tank. Additionally, fuel consumption cannot be accurately judged based solely on the relationship between the amount of fuel added and the distance traveled, as factors such as road conditions, driving speed, traffic congestion, use of air conditioning, vehicle load, fuel leakage, and fuel quality can all directly affect fuel consumption.

How to Adjust the Carburetor Mixture to be Richer or Leaner?

To adjust the carburetor mixture, tightening the screw makes it leaner (clockwise), while loosening it makes it richer. A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum created by the engine's operation. As a precision mechanical device, the carburetor uses the kinetic energy of the incoming airflow to atomize the gasoline. Its critical role in the engine can be likened to the "heart" of the engine. Carburetor-related information: 1. Classification: Carburetors are divided into simple and complex types, and can also be categorized as downdraft or sidedraft. Based on the throttle type, they can be further classified as rotary or slide type; 2. Rotary Throttle: A rotary throttle is a disk-shaped throttle that rotates around an axis, located between the carburetor throat and the intake pipe, altering the flow area of the intake passage. The slide throttle consists of a barrel or plate-shaped throttle that moves up and down at the throat to change the passage area, commonly used in motorcycle carburetors; 3. CV Type: There is also a hybrid carburetor that combines both types, where the rotary throttle is manually controlled and the slide throttle is controlled by a diaphragm. This is often used in motorcycles and is referred to as the CV type.

What is the function of the antenna on the roof of a car?

Car roof antennas serve the following purposes: 1. The antenna on a car roof, also known as a car antenna, is primarily used to receive external signals, allowing you to listen to the radio inside the car. 2. On police cars, the antenna functions to receive mobile radio transmissions, especially special band information from the police. 3. In addition to receiving signals, the car antenna also acts as a static discharger, releasing static electricity accumulated on the car's body to protect passengers and the vehicle's circuitry. 4. On some high-end vehicles, the antenna has an aerodynamic function to reduce air turbulence. Some can even serve as antennas for car phones, significantly enhancing signal strength.

What does the car skid mark OFF mean?

OFF is the deactivation button for the Vehicle Stability Control system. This system is enabled by default and can be turned off by long-pressing this button. Below is relevant information about the Electronic Stability Program: 1. Introduction: The Electronic Stability Program (ESP) is an automotive anti-skid device that can control both drive wheels and driven wheels, incorporating ABS (Anti-lock Braking System) and ASR (Anti-Slip Regulation). The ESP system is essentially a traction control system. Compared to other traction control systems, ESP not only controls the drive wheels but also the driven wheels. For instance, in cases of oversteer commonly seen in rear-wheel-drive vehicles where the rear wheels lose control and cause the tail to slide out, ESP will apply braking to the outer front wheel to stabilize the vehicle. In situations of understeer, to correct the tracking direction, ESP will brake the inner rear wheel to adjust the driving direction. 2. Mechanism of Action: The function of ESP is to automatically intervene and correct the driver's operation when it exceeds the limit. The computer controls the vehicle's movement through two methods: first, by controlling the throttle to reduce fuel supply, thereby decreasing the car's power and slowing it down; second, by applying braking to certain wheels to reduce the vehicle's speed below the limit.

What is the function of the low-pressure fuel pump?

As the most fundamental component in the engine's fuel supply system, the fuel pump is responsible for extracting fuel from the fuel tank during engine operation and continuously delivering it to the engine at a certain pressure through the fuel supply line. The fuel is then further pressurized by the high-pressure fuel pump and supplied to each cylinder in accordance with the engine's working sequence. The following are relevant details: 1. Power source: Although vehicle electrification has become an irreversible trend, the primary power source for cars currently still relies on traditional internal combustion engines. For fuel engines, general attention is usually focused on mechanical components such as pistons and cylinders, as well as electronic control units like ignition and valve timing, with little awareness of the fuel supply system, especially the fuel pump at the front end of the fuel supply system. 2. Working principle: Currently, most vehicles use vane-type electric fuel pumps. Vane-type electric fuel pumps offer advantages such as high fuel delivery capacity, high fuel pressure, stability, low noise, and long service life. This type of fuel pump primarily relies on an electric motor to drive the rotation of turbine blades, utilizing centrifugal force to draw fuel in through the intake port and expel it through the outlet port.

What are the items included in the second maintenance of a car?

Basic items include changing the engine oil and oil filter, while some models may require replacing the air and cabin air filters. The second maintenance also involves inspection and servicing of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Here are additional notes about secondary maintenance: 1. Secondary maintenance is a relatively comprehensive inspection that helps expose and resolve existing faults, ensuring that all components and overall vehicle performance are in normal condition. It plays a crucial role in car maintenance. 2. Secondary maintenance primarily focuses on inspection and adjustment-centered servicing for vehicles that have traveled a certain mileage.
