What does the rearview mirror look like when parking on a 30cm slope?

The distance between the car body and the road edge line should appear as "1 to 3 fingers' width" in the rearview mirror. Below are some scoring criteria for slope parking in Subject 2: 1. Scoring standards: If the vehicle's front bumper or motorcycle's front axle is not aligned with the pole line after stopping, and the deviation exceeds 50 cm, it results in failure; if the deviation does not exceed 50 cm, 10 points are deducted (originally 20 points). 2. Precautions: Accurately estimate the target, using a specific point on the parking pole and the windshield (or engine hood) as a reference (this point should be determined during practice due to differences in vehicle models and driver heights). When the reference point on the windshield aligns with the parking pole in a straight line, indicating the vehicle's bumper is aligned with the pole line, stop immediately.

How many points will be deducted for driving improperly on the highway with low visibility?

In cases of low visibility, driving improperly on the highway will result in a deduction of 6 points. Below are relevant precautions for driving in low-visibility weather: Plan your route appropriately: Before setting off, drivers should plan their route properly, reduce speed, maintain a sufficient safe distance, and avoid reckless overtaking. Use lights correctly: In low-visibility weather, generally turn on the low beam. If visibility is extremely poor, activate the front and rear fog lights as well as hazard lights to make your vehicle more noticeable to others. Never use high beams, as they not only impair the vision of oncoming drivers but also cause light reflection, further reducing your own visibility. Use the horn wisely: Frequent use of the horn in low-visibility conditions can alert others and indicate your vehicle's position. Additionally, if rain or snow significantly obstructs your view while driving, it's best to pull over safely and turn on the hazard lights. Avoid forcing your way through to prevent traffic accidents.

What Causes the Sound of Rain-Like Noise in a Car?

Car rain-like noise may be caused by the last section of the exhaust pipe's muffler making noise or the shock absorber rubber sleeve being damaged. More details about mufflers and shock absorbers are as follows: 1. The car muffler is a device that prevents the sound emitted by the car from propagating while allowing airflow to pass. It is the main component for eliminating aerodynamic noise and the most important device in the car's exhaust system for reducing noise. When using a muffler, it is necessary to choose materials that are fireproof, moisture-proof, and corrosion-resistant. Generally, the greater the noise reduction of the muffler, the higher the pressure loss and price. 2. The car shock absorber can improve the smoothness and comfort of the car's ride and reduce the impact force on the car body. Shock absorbers are usually installed in the car's suspension system. The performance of the shock absorber directly affects the car's driving stability and the service life of other components. When the shock absorber rubber sleeve is damaged, the damping effect is reduced, leading to the appearance of noise.

How to Check Car Engine Oil?

Method to check car engine oil: First, pull out the oil dipstick and use a tissue to completely wipe off the oil stuck to the dipstick head. Then, reinsert the cleaned dipstick all the way back in, and pull it out again. Observe the position of the oil stuck to the dipstick. If the oil level is between the upper and lower marks, it is in the ideal position, indicating the engine oil level is appropriate. If it is below the lower mark, you need to add oil. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear of moving parts and to remove sludge and varnish from the engine.

Does Using Air Conditioning in a Private Car Consume More Fuel?

Using air conditioning consumes approximately 20% of the engine's power. Below is an introduction to car air conditioning: 1. Air Conditioning Layout: Different types of air conditioning systems have varying layouts. Currently, integrated heating and cooling air conditioning systems are widely used in passenger cars. The layout involves assembling components such as the evaporator, heater radiator, centrifugal blower, and control mechanisms into a single unit, known as the air conditioning assembly. 2. Air Conditioning Components: Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. A car air conditioning system typically includes a compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The car air conditioning system is divided into high-pressure and low-pressure lines. The high-pressure side includes the compressor output side, high-pressure lines, condenser, receiver-drier, and liquid lines; the low-pressure side includes the evaporator, accumulator, return lines, compressor input side, and compressor oil sump.
