Motorcycle secondary combustion cannot be blocked. Below are the relevant explanations: Function: If the secondary air injection system is to be removed, all related tubes must be completely blocked, which is equivalent to removing the system. It is not called secondary combustion; its main function is to inject fresh air into the engine's exhaust gases, converting carbon monoxide in the exhaust into carbon dioxide for environmental purposes. Environmental Aspect: This practice is still for environmental protection. Even older vehicles had the engine's vent tube connected to the air filter to allow exhaust gases to be burned again, all aimed at environmental protection.

Where is the wheel ET value usually indicated?

The wheel ET value is typically engraved on the back of the wheel hub or printed on the packaging box/label with detailed parameters. The ET value, also known as the ET offset value, refers to the Off-set value (i.e., offset), which indicates the deviation between the wheel hub mounting surface and the centerline of the rim, measured in millimeters (MM). It can be positive, zero, or negative. Detailed explanation below: 1. Definition of Off-set: Off-set is defined as the distance between the wheel's mounting surface and the center of the rim. A positive offset indicates outward deviation, while a negative offset indicates inward deviation. 2. Impact of changing Off-set: Using wheels with a smaller positive Off-set value widens the track width, reducing body roll during cornering and improving cornering speed limits. However, this also increases the distance between the steering axis center and the tire center, making steering more difficult and increasing the load on steering components, leading to greater deformation of steering linkages. Therefore, appropriate Toe-in adjustments are required for correction.

Why can't the windows be closed by long-pressing the lock button?

The reason why the windows do not close when you long-press the lock button on the car key is that the windows have not been initialized. If the one-touch window lift function fails, it will prevent the windows from closing when you long-press the lock button. After the one-touch window lift function fails, you can perform a reset, and then the windows can be closed by long-pressing the lock button. Here is some additional information: Introduction to car keys: A car key is a tool used to switch the car on and off. Modern car keys use chips, which are part of a magnetic chip system. The reading coil in the car's ignition lock cylinder reads the chip in the key, and each chip contains fixed digital information. A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. Its features include the ability to unlock and lock the car conveniently from a distance, regardless of whether it is day or night, without needing to locate the lock hole.

Should You Press the Clutch When Braking in a Manual Transmission?

In a manual transmission, whether you need to press the clutch when braking depends on the situation; it is not a fixed procedure. The main purpose of pressing the clutch while braking is to prevent stalling. However, braking without pressing the clutch does not necessarily cause stalling. If the speed hasn't reached a critical point, there's no need to press the clutch. Additionally, pressing the clutch during a turn can sometimes make the car more prone to flipping, as it causes a sudden loss of tire grip. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving vehicles, locomotives, or other machinery. The clutch is installed between the engine and the transmission and is a key component in the vehicle's drivetrain that directly connects to the engine. Typically, the clutch is mounted with the engine's flywheel assembly and serves to engage and disengage power between the engine and the drivetrain.

What happens if you accidentally swipe another car's ETC?

Swipe others' ETC belongs to highway toll evasion, according to regulations, there will be penalties for swiping ETC. If you accidentally swipe someone else's ETC, don't panic, just enter the highway directly. When exiting the highway, stop the car and explain the situation to the toll station staff to make up the payment. Ways to prevent ETC swiping: 1. Regularly check the equipment. Frequently check whether the on-board equipment (such as the inserted small box, etc.) is working properly. 2. Slow down. When using ETC to pass through the highway toll station, the owner should slow down. Ensure smooth sensing of information and safe passage of the equipment. 3. Keep distance. The rear car should keep a distance of more than 10 meters from the front car to avoid applying the rear car's information to the front car. Maintain a distance of at least 10 meters between the front and rear cars.

Why Does the Low Beam Light Turn Off When the High Beam Is On?

There are two possible reasons: 1. If the high beam is on but one of the low beams is off, it may be due to a broken filament in the low beam bulb. This is relatively easy to fix—simply replace the bulb. 2. If both low beams are off and the filaments are intact, the car owner should check whether the low beam switch is properly connected or if the low beam fuse is functioning normally. Additional Information: Usage of Car Headlights: 1. Generally, vehicle light combination switches come in two types: lever-style and knob-style. The low beam position is marked on the switch. Rotate the light control switch handle to the low beam position to turn on the low beams. 2. Whether it's a lever-style or knob-style light switch, the high beam is activated by moving the lever. Pushing the lever toward the engine compartment keeps the high beam on continuously. Pulling it back one position turns off the high beam. To switch between high and low beams, simply toggle the light control lever back and forth.

Does idling with the air conditioning on affect the car?

Idling with the air conditioning on has a slight impact on the car's engine, as it can lead to carbon buildup, causing the exhaust pipe tailpipe to accumulate carbon deposits, and it also increases fuel consumption. Although idling with the air conditioning on does not cause significant harm to the car, it is recommended to minimize such situations whenever possible. Below is some relevant information about car air conditioning: 1. Principle of car air conditioning heating: When heating, the high-temperature antifreeze from the engine enters the heater core. At this time, the air blown by the blower may also pass through the heater core, allowing warm air to be blown out from the car air conditioning vents. 2. Refrigerant: Car air conditioning requires regular refrigerant replenishment. If refrigerant is not added for a long time, it can slow down the cooling speed and reduce the cooling efficiency. Most car air conditioning systems use R134a refrigerant.
