Why does the fuel nozzle automatically shut off during refueling?

Fuel nozzle automatic shutoff occurs because there is a trigger mechanism hidden inside the nozzle. When the fuel level reaches the nozzle tip, the automatic shutoff device activates to stop the fuel supply. It's important to note that stopping at this point doesn't mean the tank is completely full, as the upper portion of the fuel tank always reserves some space for fuel vapor to prevent excessive internal pressure. The nozzle shutoff is somewhat related to refueling speed and ambient temperature. During hot weather, pressure inside the fuel tank increases, and rapid refueling further elevates this pressure, making the fuel more likely to splash and trigger the shutoff mechanism. During refueling, air inside the tank needs to escape upward. When refueling too quickly, the air cannot escape smoothly, preventing fuel from entering properly. This may cause the intake sensor to mistakenly detect the fuel level. The "automatic shutoff" action doesn't affect the actual fuel quantity. However, drivers should pay attention to two things when refueling: first, check if the fuel pump display has been reset to zero before refueling; second, qualified fuel pumps should bear a "Mandatory Inspection Passed" label, while unqualified ones will display an "Out of Service" label.

Why Do Electric Vehicles Consume More Power in Winter?

The reasons why electric vehicles consume more power in winter include reduced battery capacity, weakened charging and discharging capabilities, and decreased activity of the battery solution. Reduced Battery Capacity: Currently, 80%-90% of electric vehicles on the market use lead-acid batteries, which have the disadvantage of being less tolerant to low temperatures. Generally, the optimal operating temperature for these batteries is 25°C. For every 1°C drop in temperature, the usable capacity of the battery decreases by approximately 0.8%. Weakened Charging and Discharging Capabilities: In low temperatures, both the charging and discharging capabilities of electric vehicle batteries weaken. This situation improves as temperatures rise. In winter, due to lower temperatures, the battery's stored power is less efficiently released, typically resulting in a power reduction of around 40%. Lower-quality batteries may experience even greater power loss. Decreased Activity of the Battery Solution: Most electric vehicles use lead-acid batteries, which generate power through chemical reactions. During winter, as temperatures drop, the temperature of the solution inside the lead-acid battery decreases, leading to reduced material activity. This results in lower conversion efficiency, increased resistance, and a decrease in the battery's discharge voltage, ultimately reducing the usable capacity and causing faster power consumption.

What Are the Hazards of Traffic Accidents?

Traffic accidents serve as a warning to us: do not exceed the speed limit; learn to control speed with intermittent braking; avoid changing lanes or merging arbitrarily; increase the safe distance in adverse weather conditions. Nine out of ten accidents are caused by speeding, with excessive speed and other major traffic violations being significant contributors to traffic accidents. When driving on highways, maintaining a safe speed is the most crucial factor in ensuring safe travel. When a driver notices the vehicle ahead braking, they must use intermittent braking to alert the following vehicle. This serves two purposes: maintaining a safe distance and reminding the following vehicle to slow down, thereby avoiding rear-end collisions. Arbitrarily changing lanes on highways can disrupt traffic flow, making it difficult for vehicles behind to react in time and leading to dangerous situations. When a driver intends to change lanes, they should check the rearview mirror to ensure no vehicles are approaching from behind, confirm there is sufficient safe distance, and then activate the turn signal at least 3 seconds in advance to inform other drivers of their intention to change lanes. When encountering low-visibility weather conditions such as fog, rain, snow, dust, or hail on highways, drivers should exercise extra caution, stay alert, maintain a safe distance, and prevent rear-end collisions.

How Often Should a Car Be Polished?

New cars should not undergo full-body polishing within the first two years, but minor scratches on specific areas can be addressed. For older cars, full-body polishing can be considered as needed, typically once a year at most, depending on the extent of scratches. If the car's paint is of good quality and remains in excellent condition, polishing is generally unnecessary for up to three years. However, if scratches appear or the paint loses its luster, polishing can be an option to restore the paint's shine, eliminate minor scratches, remove surface contaminants, and address oxidized layers. It's worth noting that the frequency of polishing should be controlled—intensive polishing more than five times can severely damage the paint. Automotive paint consists of three layers: primer, intermediate coat, and topcoat. Daily polishing is performed on the outermost layer, where the topcoat is ground down during the process, gradually thinning it and harming the paint. Excessive polishing can lead to swirl marks on the paint surface.

What Brand Are Police Motorcycles?

Police motorcycles vary by province, city, and region in terms of the brands used. Common brands include Yamaha, Suzuki, Qianjiang, Jialing, BMW, and China's Haojue. Police vehicle models are uniformly determined by the Ministry of Public Security. Vehicles include large, medium, small, and micro passenger cars, as well as specialized vehicles for emergency rescue and on-site response. Motorcycles include two-wheeled motorcycles and sidecar motorcycles. Police vehicles must be equipped with fixed police warning lights. For cars, the warning lights are installed on the top of the cabin; for motorcycles, they are installed on the right side of the rear wheel. Police warning lights and their installation must comply with national standards for special vehicle warning lights. Police vehicles must be equipped with police sirens. Police vehicle sirens must meet national standards for vehicle electronic sirens. Police license plates are divided into two types: for cars and motorcycles. Both are made of aluminum with a reflective white background. License plates must comply with the "Police License Plate Design" and industry standards for motor vehicle license plates. The Public Security Departments and Bureaus of provinces, autonomous regions, and municipalities directly under the central government implement quota management for police vehicles, uniformly assign vehicle numbers, and establish management archives.

How to Distinguish Between the Golf MK7 and MK7.5?

Golf MK7 and MK7.5 can be distinguished from three aspects: exterior, interior, and powertrain. Exterior: Although the MK7.5 Golf still maintains the body structure of its predecessor, its design has been completely revamped, adopting Volkswagen's latest family-style design language. The front bumper features extensive dark-colored trim panels and horizontal decorative strips. In terms of dimensions, the MK7.5 Golf has a longer length and wheelbase, while its weight has been further reduced. Interior: The MK7.5 Golf features a completely redesigned interior, with a semi-floating touchscreen on the center console. Additionally, it is equipped with a compact new-style electronic gear lever. Moreover, it comes with the latest MIB infotainment system, which enhances the cabin's premium feel by reducing physical buttons. Powertrain: The MK7.5 Golf offers multiple engine options, including a 1.0T three-cylinder gasoline engine, a recalibrated 1.5T four-cylinder gasoline engine, and a 1.6T four-cylinder diesel engine.
