They can be reused, but replacement is recommended. Using compressed air to blow or washing with water can remove thick accumulated dust, but it's difficult to clean the dust trapped inside the paper. The function of an air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder, preventing floating dust from being sucked into the engine, which accelerates the wear of the piston group and cylinder. According to the car's maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter element varies depending on the intake form and engine structure. It is usually located in the air cleaner on the engine intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. Using an overly dirty air cleaner in a car while driving can cause insufficient engine intake, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air cleaner clean. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder to reduce early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must first pass through the fine filtration of the air cleaner. An overly dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if you find little dust and minor blockage, you can use high-pressure air to blow it clean from the inside out and continue using it. An overly dirty air cleaner should be replaced promptly.

What is the working principle of hybrid vehicles?

Working principle of hybrid vehicles: When the vehicle starts moving, the battery is fully charged, and its energy output can meet the vehicle's requirements. The auxiliary power system does not need to work. When the battery level drops below 60%, the auxiliary power system starts the vehicle. When the energy demand is high, both the auxiliary power system and the battery pack provide energy to the drive system. A hybrid electric vehicle refers to a vehicle equipped with more than one power source, including an electric motor drive, and complies with road traffic and safety regulations. The power system of a hybrid electric vehicle mainly consists of a control system, a drive system, an auxiliary power system, and a battery pack.

How to Check the Carburetor of a Toyota Corolla?

Toyota Corolla does not have a carburetor. A carburetor automatically adjusts the mixture concentration and output according to the engine's different working state requirements. To ensure the mixed gas is evenly blended, the carburetor also has the effect of atomizing the fuel for normal engine operation. The Corolla is a compact car under Toyota, with dimensions of 4630mm in length, 1775mm in width, and 1480mm in height, and a wheelbase of 2700mm.

What light comes on when the car runs out of fuel?

When the fuel warning light illuminates, it indicates low fuel level. More extended information is as follows: Fuel indicator light illumination: Almost every vehicle has this indicator light. Some display yellow, some red, and others show yellow when fuel is low and red when critically low. Driving range: This is an important reference, but only a reference. Some vehicles display the remaining mileage after the indicator light comes on, but can still run when the mileage shows 0; some vehicles stop displaying the remaining mileage altogether after the fuel warning light comes on; and some models don't have this driving range function at all.

Do Cars Need to Be Charged?

Some do and some don't. It can be viewed from the following aspects: Plug-in: Plug-in is directly driven by fuel, and the engine can simultaneously recharge the battery. The battery and motor can also discharge to assist the engine (not simultaneously). Range extender: The range extender generates electricity and then is driven by the motor, which can be regarded as electric transmission. The engine can simultaneously recharge the battery, and the battery can also discharge to supplement power (not simultaneously). Toyota-style traditional hybrid: In Toyota-style traditional hybrids, part of the power is provided directly by the engine, and part of the power is generated and then driven by the motor. Mechanical transmission and electric transmission take effect simultaneously.

What is the purpose of installing an engine guard plate?

Installing an engine guard plate serves as a customized protective device for the engine, tailored to various vehicle models. Its primary design purpose is to prevent mud from encasing the engine, which could lead to poor engine heat dissipation. Additionally, it safeguards the engine from damage caused by impacts from uneven road surfaces during driving. Through a series of design features, it aims to extend the engine's service life and avoid vehicle breakdowns due to external factors damaging the engine during travel. Engine guard plates are categorized into: 1. Hard plastic or resin guard plates; 2. Steel or manganese alloy guard plates; 3. Aluminum alloy guard plates.
