The general structure of an automobile is basically composed of four parts: 1. Engine: The engine is the power plant of the automobile. Its function is to burn fuel to generate power, which then drives the wheels through the transmission system of the chassis to make the car move. There are mainly two types of engines: gasoline engines and diesel engines. A gasoline engine consists of a crank-link mechanism, a valve mechanism, a fuel supply system, a cooling system, a lubrication system, an ignition system, and a starting system. 2. Chassis: The chassis supports and installs the automobile engine and its various components and assemblies, forming the overall shape of the automobile, and receives the power from the engine to make the automobile move and ensure normal driving. The chassis is composed of four parts: the transmission system, the running system, the steering system, and the braking system. 3. Body: The body is installed on the frame of the chassis and is used for the driver, passengers, or loading goods. The body of a car or bus is generally an integrated structure, while the body of a truck is generally composed of a cab and a cargo box. 4. Electrical equipment: It provides power for automobile starting, driving, and automobile auxiliary facilities. It is mainly composed of a power supply, starting system, ignition system, as well as automobile lighting, signals, and auxiliary electrical facilities.

What is the fuel consumption of the Baojun 310?

Baojun 310 has 4 models on sale, including the 2020 1.2L manual luxury, value, fashion, and comfort models, all equipped with an 80-horsepower engine. The NEDC fuel consumption is 5.1L per 100 km, which is the official data. The fuel tank capacity of the Baojun 310 is 30L. A full tank can run for 30/5.1*100=588 km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, will increase fuel consumption. The car itself: Cars with larger displacements consume more fuel than those with smaller displacements because larger displacements generally mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Dirt roads, muddy roads, soft surfaces, and mountainous roads increase resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine computer controls higher RPMs to warm up the car, which also increases fuel consumption.

Can the car ETC be removed after installation?

The ETC can be removed after installation. However, the ETC will become invalid if removed by yourself, as the ETC device has an anti-tamper function. There is a small switch on the back of the ETC electronic tag. Once it is peeled off the windshield, the internal switch will automatically shut off. Therefore, you must bring the vehicle registration certificate to the ETC service provider for reactivation. ETC Billing Principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, the computer network technology is used to settle accounts with the bank in the background, achieving the purpose of paying road and bridge tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, decreases the frequency of vehicle starts and brakes, and reduces wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More Policy Support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation smart cards in key urban agglomerations will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal in the main indicators of the "13th Five-Year" comprehensive transportation development: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More Future Possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with the development directions of smart transportation, such as vehicle-to-vehicle communication and vehicle-road coordination, to provide comprehensive travel services for car owners. This means more application scenarios will support ETC applications. Precautions for Installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, resulting in a smaller driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag requires power, but generally, it does not need to be charged or have its battery replaced because there is a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper rod connected to a switch. After the electronic tag is installed, the windshield will press the anti-tamper rod in. If removed arbitrarily, the anti-tamper rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions for Using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for ETC lane passage is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, resulting in failed billing. When using a debit card to bind ETC, insufficient balance will also cause billing failure.

Can You Keep Driving When the Airbag Light Is On?

You can continue driving when the airbag warning light is on, but you should visit a repair shop as soon as possible. Otherwise, the airbag may not deploy in an accident, posing a safety risk. Below are the reasons why the airbag warning light may illuminate: 1. Normal Operation: The indicator light turns on when starting the car but goes off after self-checking, typically within about 5 seconds. This is normal. If it stays on, it indicates a fault. 2. False Alarm: Since airbags are controlled by circuits, various factors can trigger the light, such as severe battery depletion, which may cause the airbag system to report a low-voltage signal and generate a fault code. In such cases, clearing the code resolves the issue. 3. Actual Fault: There are multiple potential causes, including airbag malfunction, clock spring failure, impact sensor issues, loose airbag connectors, or broken wiring. It is necessary to use a diagnostic tool to read the fault code, identify the problem, and fix it promptly.

Can cleaning restore a faulty EGR valve?

Cleaning the EGR valve can resolve the issue. During cleaning, it is necessary to use a carburetor cleaner to clean the intake passage, the carbon deposits inside the EGR valve, and the engine's throttle valve. When cleaning the intake passage and the EGR valve connecting pipe, the method of burning the pipeline can be employed. The impacts of a faulty EGR valve are as follows: 1. Affects the normal operation of the engine: A faulty EGR valve can disrupt the engine's normal operation, leading to unstable idle speed or stalling at idle, flashing fault lights, oil burning, reduced power, black smoke from the exhaust pipe, and other phenomena that affect the car's performance. 2. Reduced engine power: If the EGR valve is damaged and remains in the open state, it can cause the engine to stall at idle, have unstable idle speed, experience weak acceleration, or increased fuel consumption. Additionally, it may be accompanied by a decrease in engine power. 3. Impacts vehicle exhaust emissions: If the EGR valve is damaged and remains in the closed state, it can affect the vehicle's exhaust emissions, potentially causing them to fail to meet standards and resulting in failure to pass annual inspections.
