What is the structure of a fuel gauge?

1 Answers

The fuel gauge consists of a metal rod and a float, with the float typically made of foam plastic. The end of the metal rod is connected to a variable resistor. A resistor is a device used to impede the flow of electric current. The greater the resistance, the smaller the current that passes through. The fuel gauge is a very simple device. The current flowing from the sender passes through a resistor, which may be wrapped around or located near a bimetallic strip. The bimetallic strip is connected to the pointer of the fuel gauge via a linkage. When the resistance increases, the current through the heating coil decreases, causing the bimetallic strip to cool down. As the strip cools, it straightens, moving the fuel gauge pointer from full to empty. The function of the automotive fuel gauge is quite advanced, capable of displaying the fuel level in the tank in real-time, accurately informing the owner about fuel consumption and remaining tank capacity. The fuel gauge can indicate whether refueling is needed and how much distance can be traveled after refueling. Essentially, the fuel gauge acts as a warning light for the vehicle's life. It is an indicator on the engine that displays fuel level, either via a pointer or digital readout. Automotive fuel gauges are mainly divided into two types: digital display fuel gauges and pointer display fuel gauges.

Why Won't My Kia Start?

Possible reasons include steering wheel lock, gear not in P position, smart key battery depletion, dead car battery, or lack of antifreeze. Below is relevant information: 1. Introduction: Kia refers to Kia Motors Corporation, the earliest automobile manufacturer in South Korea. In 2000, it merged with Hyundai Group to form Hyundai-Kia Automotive Group, which ranks as the world's fifth-largest automaker by production volume. 2. Company History: Established in December 1944 as the predecessor of Kia Motors, it initially operated as a small factory handcrafting bicycle components. In March 1952, it manufactured Korea's first bicycle named Samchully, subsequently rebranding as Kia Industries.

Why Does the Car Charger Get Hot?

It is normal for a car charger to get hot. There is energy loss during the conversion between AC and DC power. Most chargers use highly efficient switching power supplies, but due to size limitations, they generally lack a PFC (Power Factor Correction) circuit, resulting in a power factor of less than 0.7. The remaining energy is mostly converted into heat. Precautions for an overheating charger: 1. Charge in a cool environment: If the car charger overheats, it is best to charge it in a cool place during summer, such as an air-conditioned room. This will prevent the charger from overheating. 2. Use the original charger: When charging your phone, always use the original charger to ensure stable output current and protect the battery. Original chargers may still get warm but will not overheat due to built-in protection mechanisms. If the charger overheats, it may be counterfeit or non-original. 3. Avoid using the phone while charging: Using the phone while charging can cause the charger to overheat, as it has to work longer than usual. This can damage the charger and reduce its lifespan.

Is the Braking Distance Longer or Shorter in Rainy or Snowy Weather?

In rainy or snowy weather, the braking distance will be extended. During such weather, the road surface is covered with water, snow, or ice, which reduces the roughness between the car and the ground. With the pressure between the car and the ground remaining unchanged, the friction force the car experiences during braking decreases. Since force is the cause of changing an object's state of motion, the smaller the friction force, the harder it is to alter the car's motion state. Therefore, the braking distance becomes longer. Relevant information about braking is as follows: 1. Introduction: Refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transport, or machinery. 2. Principle: The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.

Which factory produces the Ping An Lu tires?

Ping An Lu truck and bus tires are produced by Shandong August 1st Tire Company. Here is more information about automotive tires: 1. Numerical meanings: Tire data indicates the tire section width, aspect ratio, and rim diameter in inches. For example, a tire with the specification 225/65/R17 has a section width of 225, an aspect ratio of 65, R stands for radial construction, and 17 is the rim diameter in inches. 2. Function: Vehicle tires help reduce and absorb shocks and vibrations during driving, preventing damage to car components caused by severe vibrations.

Does a car still need inspection after wading through water if everything seems normal?

Even if everything seems normal after a car has waded through water, the following items should still be checked: 1. Check if the brakes are functioning properly: After successfully wading through water, do not accelerate immediately. Continue driving at a low speed for a while and pump the brakes a few times on a dry section of road to prevent brake failure and potential rear-end collisions. This method not only checks the brake functionality but also ensures sufficient friction between the brake discs and pads, helping residual moisture evaporate quickly and restoring braking power sooner. 2. Inspect key components such as the air filter: Besides checking the brake pads yourself, it is recommended to take the vehicle to a 4S shop for inspection after wading through water, especially focusing on critical areas like the air filter and wiring harness interfaces in the engine compartment.

What are the symptoms of a broken cell in a car battery?

After a car battery cell breaks, the voltage cannot reach the normal range, making it harder to start the car, and the horn may not sound as loud as before. Below is more information about car batteries: 1. Introduction: A car battery, also known as a storage battery, works by converting chemical energy into electrical energy. The commonly referred-to car battery is a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Reasons for battery depletion: Frequent short-distance driving and stop-and-go conditions can cause the battery to remain undercharged for extended periods, shortening its lifespan. Driving at a steady speed on the highway for 20-30 minutes can provide sufficient time for the battery to recharge.
