Is It Necessary to Clean the Exterior of the Engine?

Cleaning the exterior of the engine is necessary. Functions of cleaning the engine exterior: After prolonged use, a lot of dust will accumulate on the surface of the engine. If not cleaned for a long time, this dust will turn into a thick layer of sludge after being baked by the high temperature of the engine, and it may also corrode some engine components. Cleaning the engine exterior not only maintains cleanliness but, more importantly, reduces the damage caused by corrosive substances to the external parts of the engine, thereby extending the lifespan of the engine components. Precautions for cleaning the engine: If the car is used in a very complex environment, not only should the exterior of the engine be cleaned, but the interior should also be cleaned. After a period of use, dust and impurities entering the engine compartment can form harmful substances like carbon deposits and gum on the engine surface. If not cleaned for a long time, these harmful substances can turn into sludge, seep into the engine surface, and cause damage to the engine.

Can I call the police if my parked car gets scratched?

It is useful to call the police if your parked car gets scratched. If the vehicle was not parked illegally, you can choose to report it to the police. The parking precautions are as follows: When parking in winter: Especially for car owners in northern China, many prefer to lift the wiper blades after parking. The purpose of this "extra step" is actually to protect the wipers. In northern winters, if it snows and the wipers are not lifted, the snow on the windshield can freeze the wipers. When you need to use the wipers the next day (e.g., in snowy or rainy weather), forgetting to remove the ice and turning on the wipers directly can burn out the wiper motor because the wipers are frozen and unable to move. When parking in summer: Many car owners also like to lift the wiper blades, again to protect them. In summer, if the car is parked outside under the scorching sun, the temperature on the windshield can exceed 60°C. If the wipers are not lifted, the rubber material of the wipers will remain tightly pressed against the windshield.

Is driving at 105 km/h in a 100 km/h speed limit considered speeding?

Driving at 105 km/h in a 100 km/h speed limit is considered speeding. Here are the detailed explanations: 1. Speed limit regulations: A speed limit refers to the designated maximum driving speed for a certain length of road, serving as a reminder for drivers to control their speed appropriately within that section. Exceeding the specified speed constitutes speeding, and drivers must strictly adhere to the posted speed limits while on the road. 2. Purpose of speed limits: Speed limits are implemented to prevent dangerous speeding, maintain normal and stable road conditions, and are determined based on factors such as the number of lanes, types of vehicles, and traffic volume during specific periods for a given road section, establishing safe and reasonable speed requirements. 3. Specific speed limit values: Typically, the specific speed limit values are communicated to drivers entering the road section via electronic navigation or road signs. Generally, speed limits on highways range from 60 km/h to 120 km/h, while on primary roads, the speed limits range from 60 km/h to 100 km/h.

Can You Drive with 80 Tire Pressure?

Tire pressure of 80 cannot be driven. A tire pressure of 80 refers to the vehicle's tire pressure being 0.8 atmospheres, which is far below the normal tire pressure value. Immediate pressurization of the vehicle's tires is required. According to the international GBT2978-2008 standard, the recommended tire pressures for different tires are as follows: standard tires should be 2.4-2.5 bar; reinforced tires should be 2.8-2.9 bar; while the maximum pressure should not exceed 3.5 bar. The hazards of low tire pressure are as follows: increased friction coefficient with the road surface, leading to higher fuel consumption; causing the steering wheel to become heavy and prone to deviation, which are factors detrimental to driving safety; increased movement of various parts of the tire, leading to abnormal heating due to excessive rolling; reduced functionality of the cord and rubber, causing delamination or cord breakage, excessive friction with the rim leading to damage at the bead area, and abnormal wear; multiplied friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a sharp decrease in strength, etc.

Is It Dangerous to Leave Lithium Batteries in the Car During Summer?

Leaving lithium batteries in the car during summer is extremely dangerous, as the batteries can explode when exposed to high temperatures. Here is some relevant information about power batteries: 1. High-temperature resistance: In high-temperature tests, ordinary lithium batteries can withstand temperatures of 200 degrees, 500 degrees, and even 800 degrees. However, such extreme temperatures are rarely encountered in daily life. 2. Temperature limits: Under high-temperature conditions, significant heat fluctuations can occur inside the battery, leading to safety hazards such as explosions. The temperature limit for lithium batteries is generally set between 40-60 degrees. Most batteries are labeled with explosion-proof valves, while high-temperature-resistant lithium batteries can withstand up to 800 degrees.

What does a range of 40km mean?

Range of 40km means the maximum distance is 40km. Here are the relevant explanations: 1. Fuel engine range: Range refers to the total distance that vehicles like cars or ships can travel continuously with maximum fuel reserve. In other words, an electric vehicle's range is the distance traveled from a fully charged state of the power battery until the test ends as per standard regulations. 2. New energy vehicle range: For new energy vehicles, the maximum battery-supported range refers to the farthest distance the vehicle can travel in pure electric mode relying solely on the battery's charge.
