What are emergency vehicles?

Common emergency vehicles include 120 ambulances, 110 police cars, and 119 fire trucks. They are used for emergency mobilization of various military branches, emergency deployment of weapons and equipment, strategic logistics, communication equipment, battlefield personnel evacuation, and material resettlement. Disaster response vehicles can transport relief supplies, medical support materials, wounded soldiers, rescue personnel, victims, disaster-affected individuals, resettlement materials, and daily necessities for displaced persons. Maintenance of emergency support vehicles: 1. Check the vehicle's safety features such as brakes and engine oil. 2. Ensure emergency equipment and supplies are intact and functional; verify sufficient material preparation. 3. Maintain vehicle hygiene. 4. Check if communication devices, vehicle lights, and signal lights are operational.

Why is the fuel consumption gauge fluctuating erratically?

Average fuel consumption is a calculated value used to display the fuel consumption over a certain distance traveled. During driving, significant changes in external air temperature or unstable engine coolant temperature can cause the computer to fluctuate greatly in calculating the fuel injection volume, leading to constant erratic fluctuations in the average fuel consumption gauge. Relevant information about fuel consumption is as follows: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Testing method: The test can be conducted on the road or on a chassis dynamometer, and then the fuel consumption per 100 kilometers is calculated using the "flow meter method" or "carbon balance method."

What are the effects of fuel pump pressure relief on a vehicle?

Under normal circumstances, the fuel pressure provided by the fuel pump is generally around 3-3.5 bars. The gasoline pressure may vary depending on the vehicle model. The function of the fuel pump is to draw gasoline from the fuel tank and deliver it through the pipelines and fuel filter to the carburetor float chamber. It is precisely because of the fuel pump that the fuel tank can be placed far from the engine, at the rear of the vehicle, and below the engine. If the fuel pump's pressure is insufficient, the following symptoms may occur: 1. A buzzing noise from the fuel pump under the rear seat while driving. 2. Weak acceleration, especially with noticeable hesitation during sudden acceleration. 3. Difficulty starting the vehicle, or failure to start. 4. The engine warning light on the instrument panel remains illuminated.

How far can you drive when the fuel gauge is empty?

When the car's fuel gauge shows a remaining range of 0, it can still continue to drive for some distance. Around 50 kilometers, which provides sufficient mileage to find a gas station. Some vehicles may display a remaining range of 0 after the warning light comes on, but they can still run. The actual range is greatly influenced by driving habits and road conditions. Additional information: Fuel pump cooling: The fuel pump is cooled by gasoline, specifically the gasoline that passes through the fuel pump during operation, not by being fully submerged in gasoline. As long as the car can run normally and the fuel pump supplies fuel properly, it won't be damaged. The vehicle uses a fuel level sensor: to detect the remaining fuel in the tank. The specific principle involves a float on the fuel surface that detects the height of the fuel level and converts it into an electrical signal through a potentiometer.

What are the symptoms of a faulty fuel pump control module?

When the fuel pump fails, the following symptoms may occur: weak acceleration with a jerking sensation during sudden acceleration; difficulty starting the engine; buzzing noises while driving; illumination of the engine warning light; and engine shaking or vibration. Causes of fuel pump failure include: poor fuel quality, where various impurities in the fuel tank are sucked into the fuel pump motor, causing damage; waiting until the fuel light comes on to refuel, which can lead to the fuel pump operating at a lower level without adequate cooling and lubrication; and failure to replace the fuel filter, which can cause severe blockage in the fuel supply system, making it difficult for the fuel pump to operate and leading to damage due to prolonged high-load conditions.

What Are the Common Knowledge Points for Car Usage?

There are several key points to know about car usage: 1. Air conditioning usage: Car air conditioning mainly consists of three parts: air direction, fan speed, and temperature. 2. Use of recirculation mode: Recirculation mode means the air inside the car circulates without outside air. Use this mode when the outside air quality is poor or during summer. 3. Car wash precautions: Avoid rinsing a car that has been exposed to direct sunlight with cold water. In summer, the surface temperature of the car paint can become very high after prolonged exposure to sunlight. Washing the car at this time can cause the paint to contract suddenly due to the cold water, leading to damage. 4. Car tires: The typical lifespan of a car tire is three to five years. Even if the car is driven infrequently, tires should be replaced promptly after exceeding this period. 5. Dealing with a punctured tire: Always monitor tire pressure and avoid sudden acceleration or aggressive driving. If tire pressure is abnormal, find a safe place to replace the tire immediately.
