Do You Need to Wait for the Voice Confirmation After Parallel Parking?

Do You Need to Wait for the Voice Confirmation After Parallel Parking? Here is an introduction about parallel parking: 1. Types and Methods: There are three most common types of parallel parking. The first is the 'Non'-shaped parallel parking, commonly seen in large shopping malls. The second is the roadside 'One'-shaped parallel parking, also known as side parking. The third is the less common diagonal parallel parking. 70% of driving school students find side parking more challenging. 2. Meaning: Parallel parking has been a mandatory test item for obtaining a small car driver's license since 2013. 3. Parking Tips: Control the driving route during the test. The car's driving route mainly depends on the speed of steering wheel rotation and driving speed. When reversing, aim for the side line, correct the direction in time, and keep the car straight when entering the parking space.

How Many Kilometers Should a Major Car Maintenance Be Performed?

Major car maintenance should be performed every 20,000 kilometers. Changing the engine oil and oil filter is a mandatory task for every maintenance. Due to the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance greatly deteriorates. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. The air cleaner's role is to block dust and particles from being inhaled during the engine's intake process. If the filter is not cleaned for a long time, it can lead to dust being sucked into the engine, causing abnormal wear on the cylinder walls. The air cleaner must also be replaced during major maintenance.

What is the standard for automobile toe-in?

The standard for automobile toe-in is between 0 and 12mm. The front wheel toe-in can be adjusted by changing the length of the tie rod. During adjustment, the distance difference between the front and rear of the two wheels should conform to the specified toe-in value based on the measurement position prescribed by the automobile manufacturer. To ensure stable straight-line driving of the vehicle, the steering wheels should have an automatic return function. That is, when the steering wheels are deflected due to accidental external forces (such as hitting a stone), they should immediately return to the straight-line driving position after the external force disappears. This return function is guaranteed by the positioning parameters of the steering wheels, and front wheel toe-in is one of these positioning parameters.

What is the main function of the activated carbon canister?

The main function of the activated carbon canister is to reduce the emission of gasoline vapors from the automobile fuel tank and carburetor. Below is relevant information about the activated carbon canister: Function of the activated carbon canister: The activated carbon canister, also known as the automobile fuel evaporation emission control device, is a canister filled with activated carbon. It is used to adsorb fuel vapors generated by the temperature difference ventilation in the automobile fuel tank after parking. Additionally, under the China VI standard, it is also used to absorb fuel vapors produced during refueling. Advantages of the activated carbon canister: When the engine is ignited, the gas from the activated carbon canister is drawn into the engine intake pipe through the canister purge valve. The opening, closing, and absorption level of this control valve are determined by the electronic fuel injection system's control unit. The activated carbon canister significantly reduces atmospheric pollution caused by exhaust emissions.
