Are There Airbags in the Rear Seats of Cars?

High-end brand cars have airbags in the rear seats, while most ordinary vehicles are not equipped with them. Most car models are equipped with front airbags for the driver and front passenger, front and rear side airbags, and side curtain airbags, but models with rear seat airbags are still rare, making them a high-end safety feature. Rear side airbags are positioned on the side of the rear seats near the windows. Typically, there are seven sensors in the car. When the sensors detect a side impact, they automatically deploy to protect the safety of the driver or front passenger. Airbags mainly consist of components such as sensors, a microprocessor, a gas generator, and the airbag itself. The sensors and microprocessor are used to determine the severity of the crash and transmit signals. The gas generator, based on the signals, triggers an ignition action, igniting solid fuel to produce gas that inflates the airbag, causing it to rapidly expand. The airbag capacity is approximately (50-90) liters. Precautions for airbags: Do not place items above or in front of the airbag. The force exerted when an airbag deploys is extremely strong, and items could be ejected, causing secondary injuries. Always wear a seatbelt. Without a seatbelt, the airbag can become a ticking time bomb. Contact between an occupant and an incompletely or prematurely deployed airbag can result in unbalanced impact forces, causing greater harm to the occupant. Do not let children sit in the front passenger seat. In an accident, the immense impact force can cause the seatbelt to fracture a child's sternum, and the airbag can suffocate the child.

What Causes Diesel Fuel to Burn Poorly?

Diesel fuel burns poorly due to slight deviations in spark plug ignition timing, impurities in the air filter, and other factors. Reasons related to diesel fuel: Poor diesel quality: The performance indicators of the diesel used do not meet standard requirements, leading to incomplete combustion and black smoke. Additionally, low-quality diesel can damage the diesel filter, causing the diesel inside the engine to degrade, which results in black smoke. Clogged air intake: Diesel engine fuel tanks are not sealed, and prolonged exposure to air inevitably allows impurities and dust to enter the air filter. These particles can clog the air intake, preventing sufficient air supply during diesel combustion, which easily leads to incomplete combustion and black smoke. Insufficient compression: One of the conditions for diesel combustion is a pressurized environment. However, wear on components like valves and piston rings can reduce compression pressure, failing to meet combustion requirements. This worsens combustion conditions, leading to black smoke. Solutions: Modern fuels are high-cleanliness products with various additives to aid combustion and meet emission standards. Three years ago, diesel from Shandong refineries typically had a density above 0.85g/m³, with some even reaching 0.88g/m³ or 0.89g/m³. The higher density allowed for more complete combustion of heavier components, making the diesel feel more powerful. However, with increased crude oil refining in Shandong, the root cause of high density has been addressed. Additionally, the proportion of heavy components like catalytic diesel has significantly decreased, and post-hydrotreatment diesel density has dropped considerably.

Can You Stick Your Head Out During Curve Driving?

Curve driving does not allow sticking your head out, otherwise it will result in failure. During the Subject 2 driving test, candidates are not permitted to lean their heads out of the window to check vehicle operations; they must rely solely on rearview mirrors for observation. According to test regulations, not only is leaning out prohibited, but no part of the body may extend outside the vehicle during any movement test. Violation will result in failure. The Subject 2 driving test consists of five tasks: reverse parking into a garage, hill start, parallel parking, curve driving, and right-angle turns. Among these, reverse parking and parallel parking require controlling the vehicle by observing the rearview mirrors. Relevant officials have also stated that under the new traffic regulations, not only is leaning out prohibited, but no part of the body may extend outside the vehicle during any movement test. Violation will result in failure. Tips for curve driving: When entering an S-curve, pay attention to the position of the front of the car. When the midpoint of the front touches the right yellow line, gradually steer to the left. Start with half a turn, keeping the left corner of the front aligned with the yellow line. When the left corner is about to cross the yellow line, steer a bit more. If the left corner fails to touch the yellow line, slightly adjust the steering back. When the front of the car is centered at the curve junction, quickly straighten the steering, usually requiring about one full turn. When the midpoint of the front touches the left yellow line, steer half a turn to the right, then make minor adjustments, following the curve and continuously adjusting the steering wheel. While turning, use peripheral vision to glance at the left and right rearview mirrors to monitor the distance between the rear wheels and the boundary lines, making appropriate adjustments to avoid crossing the lines.
