What is the difference between a 3-cylinder engine and a 4-cylinder engine?

What are the reasons for antifreeze suddenly leaking all over the ground?

The reasons for the decrease in antifreeze include: the auxiliary water tank being overfilled, causing the antifreeze to overflow from the reservoir due to rising water temperature during driving; natural evaporation over time; leakage of antifreeze, which may not be visible to the naked eye but can be detected through pressure testing; and antifreeze seeping into the engine and participating in combustion. The functions of antifreeze: In cold weather, it prevents parts from system failures or cracking due to cooling issues, manages rust prevention, and prevents excessive scale buildup that could clog pipes. It has functions such as anti-corrosion, anti-scaling, anti-boiling, anti-freezing, and anti-rust. Precautions: Try to use the same brand of antifreeze; most antifreeze has a validity period of two years, so ensure the product is within its validity period when adding; avoid mixing with water, as it can produce sediment and severely affect the normal functions of the antifreeze.

Does Using the Heater in New Energy Vehicles Consume More Electricity?

Using the heater in new energy vehicles does consume more electricity, increasing power consumption by at least 10%. Introduction to New Energy Vehicles: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving. These vehicles feature advanced technical principles and incorporate new technologies and structures. Classification of New Energy Vehicles: New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

What is the success rate of traffic violation appeals on 12123?

The success rate of traffic violation appeals on 12123 is approximately 20%. Appeals are not for traffic violations: It's important to note that appeals on the traffic management 12123 platform are not for traffic violations, but rather for situations such as when the phone number registered with the traffic management department has been canceled, is no longer in use, or cannot receive text messages during registration. If you need to appeal a traffic violation (i.e., administrative reconsideration), you must go to the traffic police department. The basic appeal process is as follows: Before appealing, you must first go to the traffic police station to handle the violation, pay the fine, and receive penalty points. At this time, you will receive a penalty decision from the traffic police. In the traffic violation processing hall or administrative reconsideration hall, request an administrative reconsideration application form. Bring the completed administrative reconsideration application form, penalty decision, ID card, driver's license, and vehicle registration certificate to the local public security authority for processing. It is best to bring both the originals and copies of all documents.

What is the difference between position lights and low beam headlights?

The differences between position lights and low beam headlights are as follows: Illumination range: Position lights mainly serve to alert other vehicles and pedestrians, with an illumination range typically around the vehicle's perimeter, not extending too far; low beam headlights are designed for a larger illumination range, usually covering 30-40 meters. Installation position: Position lights are installed at the edges of the vehicle, while low beam headlights are installed at the front of the vehicle. Position lights are generally turned on under the following circumstances: At night: According to traffic regulations, position lights must be turned on when driving at night. In foggy conditions: Turning on position lights can serve as a warning to other vehicles. During rainy days or when visibility is poor: Turning on position lights can alert other vehicles and pedestrians.

Does using car heater or air conditioning consume more fuel?

Using the air conditioning in a car consumes more fuel. While the heating system does not completely avoid fuel consumption, its usage is minimal and can generally be ignored. Heating Principle: Most car heating systems consist of a heater core connected to the engine's cooling circuit. The coolant, which absorbs heat from the engine, flows through this heater core. The heater core functions similarly to a water radiator, where the blower fan directs the heated air into the cabin to provide warmth. Therefore, the heating process does not consume additional engine energy but rather reuses the energy from the cooling system, resulting in negligible fuel consumption. Cooling Principle: The car air conditioning cooling system comprises a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower fan, all connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the cooling system operates, the refrigerant circulates through this closed system in different states.

Where should ETC be installed on a vehicle?

The installation position of ETC for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the upper part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, 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, it should be installed in the microwave sunroof strip. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the owner needs to provide the original and photocopy of the 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. A bank card for deducting highway tolls is also needed. The vehicle must be under the name of an individual aged between 18 and 60. For units or companies, the organization code certificate (or business license) and official seal are required. Here are the precautions for installing ETC: Do not block the view. It is best to install it behind the rearview mirror: Many car models have a large inclination 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 behind the rearview mirror on the right side can avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power but generally does not need to be charged or have its battery replaced because it has a solar panel on the back that can charge itself. 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 guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed casually, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and making it unusable. You will need to go to 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, keep a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The speed limit for ETC lane recognition is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to a failed deduction. When using a debit card bound to ETC, insufficient balance will also cause a failed deduction.
