How Does a Carburetor Work?

The working principle of a carburetor is as follows: 1. Air from the outside is filtered and then enters the carburetor, with the amount of air intake controlled by the position of the choke valve. 2. The air rushes through the venturi inside the carburetor, creating suction that draws fuel from the float chamber through the nozzle and atomizes it. 3. The atomized fuel mixes with air and is then drawn into the cylinder through the intake manifold. The amount of the air-fuel mixture is controlled by the throttle pedal, which operates the throttle inside the carburetor. 4. The amount of fuel pumped into the float chamber by the fuel pump is controlled by the float inside the float chamber. The float rises and falls with the fuel level in the float chamber. When the float chamber is filled with gasoline, the float rises and uses its needle valve to block the fuel inlet.

Why do the brake lights stay on without pressing the brake pedal?

Since the rear lights of a car are used for width indication at night, they must remain constantly illuminated. Below is relevant information about brake lights: 1. Car rear brake lights: Rear lights refer to white lights installed as close as possible to the rear of the vehicle, displaying uninterrupted illumination. From directly behind the vehicle to 67.5° on each side, they emit a horizontal light arc of 135°. Their visibility distance is required to be 3 and 2 nautical miles based on the length of the vessel. They are used to indicate the vessel's movement and identify the movement of other vessels, aiding in determining crossing or overtaking situations. 2. The function of car brake lights: The purpose of rear brake lights and high-mounted brake lights is to make it easier for vehicles behind to notice when the vehicle ahead is braking, thereby helping to prevent rear-end collisions. The brake indicator light on the dashboard serves to alert the driver when the rear brake lights are activated.

Why Did the Driving School Suspend Exams?

The reason for the suspension of driving school exams is due to an upgrade of the driving test system. Below is some relevant information about driver's licenses: 1. Driving requirements: According to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses,' the scope of a C1 driver's license covers small and micro passenger vehicles, as well as light and micro cargo vehicles; light, small, and micro special-purpose vehicles; and small passenger vehicles with a seating capacity of 9 or fewer. Based on these standards, a C1 license does not permit driving vehicles with more than 9 seats. 2. Requirements for test vehicles: Light general cargo vehicles with a length of no less than 5 meters, or small general passenger vehicles with a length of no less than 4 meters, or cars with a length of no less than 4 meters.

Can compulsory insurance be claimed for a motorcycle without a driver's license?

Motorcycle riding without a license can claim compulsory traffic insurance, but commercial insurance does not cover compensation. Compulsory insurance stipulates: "In the event of a road traffic accident caused by the insured motor vehicle resulting in personal injury, death, or property damage to victims other than the vehicle's occupants or the insured, the insurance company shall compensate within the liability limits of the compulsory motor vehicle traffic accident liability insurance as prescribed by law. If the losses from the road traffic accident are intentionally caused by the victim, the insurance company shall not compensate." Circumstances under which the insurance company does not compensate: The driver does not have a valid driving license or is under the influence of alcohol; the insured motor vehicle is involved in an accident during theft or robbery; the insured intentionally causes a road traffic accident.

What Causes Jerking During Acceleration When Pressing the Gas Pedal?

Jerking during acceleration when pressing the gas pedal may be caused by fuel line blockage. Below is more information about vehicle fuel consumption: 1. Fuel Consumption Overview: The term 'fuel consumption per 100 kilometers' refers to the amount of fuel a vehicle consumes when traveling 100 kilometers on the road at a certain speed, serving as a theoretical indicator for the vehicle. Currently, microcars have relatively low fuel consumption, ranging from 4 to 5 liters per 100 kilometers, while for other vehicle types, a consumption not exceeding 15 liters per 100 kilometers is considered relatively low. 2. Influencing Factors: There are many factors that affect a car's fuel consumption, such as driving habits, road conditions, vehicle load, etc. Different vehicle models also have an impact; even for the same model, fuel consumption can vary. Therefore, the actual fuel consumption of a car is not fixed.

Which Gear is More Fuel-Efficient for Motorcycles

In theory, higher gears result in lower fuel consumption, and this holds true in practical performance as well. However, the prerequisite still depends on the engine RPM, as it is the fundamental condition for gear shifting. If the RPM fails to meet the shifting requirements, smooth gear shifting and normal vehicle operation cannot be achieved. From practical riding experience, maintaining the engine RPM at a moderate level tends to make the vehicle relatively more fuel-efficient. This is because, under such conditions, the engine bears the least load, operates more smoothly, and the throttle opening is not too large, resulting in relatively less fuel entering the cylinder. The theoretically most fuel-efficient state of a vehicle depends on its economical speed, while the actual performance is determined by the coordination between engine RPM and gear selection. To intuitively achieve this state, one needs to refer to the vehicle's current speed. Therefore, in the end, achieving fuel efficiency in a vehicle still revolves around maintaining the economical speed.
