What is the difference between 12V and 24V car fans?

The difference between 12V and 24V car fans lies in their compatible voltages and application environments. Here are the details: 1. Differences: A 12V car fan can only be matched with a 12V DC power source and cannot be adapted to a 24V DC power source. A 24V car fan plugged into a 12V power source will noticeably slow down or even fail to work. 2. Application environments for 12V and 24V power sources: 12V voltage is typically used for engines with small compression ratios and displacements. 24V power sources are suitable for large vehicles with high compression ratios and large displacements. Because large vehicles have high compression ratios and significant friction coefficients in various parts, the starting force is hindered, so high-voltage and high-current starters are required for ignition.

What is the Difference Between New Energy Vehicles and Electric Vehicles?

New energy vehicles and electric vehicles differ in the following aspects: 1. Battery: New energy vehicles use lithium batteries, while electric vehicles generally use lead-acid batteries. Most new energy vehicles support fast charging, whereas electric vehicles do not. 2. Manufacturing process: New energy vehicles are produced according to automotive manufacturing standards, whereas electric vehicles, although following automotive processes, still have significant differences compared to cars. 3. Materials and components: The components of electric vehicles are inferior to those of cars, such as body door panels. Both new energy vehicles and electric vehicles use steel plates with a thickness of 1.5mm. 4. Power motor: New energy vehicles mostly use permanent magnet synchronous motors, while electric vehicles commonly use DC or AC motors.

What does OBD fault mean?

OBD stands for "On-Board Diagnostics". When a fault occurs in systems or related components connected to the control system, it can send warnings to the driver. The OBD device monitors multiple systems and components including the engine, catalytic converter, particulate trap, oxygen sensors, emission control system, fuel system, and EGR. Additional information: Below are details about OBD faults: 1. Identifying the source of the fault to clear the OBD indicator light can be somewhat challenging. The simplest method is by reading the fault codes, because OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the capability to detect and analyze emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes. Therefore, by reading the fault codes, we can quickly and accurately determine the nature and location of the fault. 2. OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the capability to detect and analyze emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes, and alerts the driver through the malfunction indicator light. The ECU ensures access to and processing of fault information through a standard data interface.

What lights to use when going straight through an intersection in Subject 3?

In the voice command lighting test of Subject 3 driving exam, when hearing the instruction "go straight through the intersection", the examinee should use low beam headlights; another scenario is when prompted to pass through an intersection without traffic lights, then the examinee should alternately switch between high and low beams twice. Exam tips: 1. Upon hearing "approaching intersection", the examinee should brake to reduce speed, observe traffic conditions from both sides, and pass safely. At signalized intersections, follow traffic light instructions. If traffic congestion prevents movement, stop the vehicle behind the safety line and wait - stopping within the intersection is prohibited. 2. If there's a crosswalk, follow crosswalk operation requirements simultaneously. 3. Following the five essentials of defensive driving: "left foot not constantly pressing, right foot not idly pressing" - when not accelerating, the right foot shouldn't rest on the accelerator pedal but should hover over the brake pedal. When stopping to yield, always engage the handbrake first before shifting to neutral. Never stop while holding the clutch in gear when waiting. Restarting must use half-clutch technique before releasing the handbrake. 4. During night tests, "alternate between high and low beams" should be demonstrated more than twice as a signal.

Can the car run the air conditioner without turning off the engine?

It is possible to run the air conditioner without turning off the engine for a short period of time. However, doing so for an extended period can lead to increased carbon deposits in the car's engine. The car air conditioner is an important comfort feature that can provide both cooling and heating, making it essential during both winter and summer seasons. When the car air conditioner is in cooling mode, the compressor clutch engages, and the engine drives the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, thereby cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the car air conditioner to emit cold air from the vents.

Where to Place the ETC on the Car Windshield?

The ETC installation position for small cars is generally in the upper-middle part of the front windshield, while for large vehicles like trucks and buses, it is installed in the lower-middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters in height, with an installation angle between 30 to 90 degrees. For vehicles with built-in or later-added explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway toll fees is required, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for ETC installation: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large tilt angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spot. Installing it on the right side behind the rearview mirror can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If removed casually, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note that: the ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic toll deduction for the wrong vehicle. The recognition speed for ETC lanes is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.
