30cm refers to the distance from the corner of the garage to the body of the car. Here are the specific techniques for finding the 30cm distance: 1. Observe the position of the engine hood: After hearing the voice prompt, you need to drive forward and to the right. When you see the right front corner of the engine hood at the 1/3 position align with the roadside line, the distance between the car body and the roadside line is exactly 30cm. 2. Look at the raised part of the wiper: From the driver's seat, when the raised part of the wiper aligns with the right side line, the distance is approximately 30cm. 3. Look at the right front door handle: Observe the right front door handle in the right rearview mirror. If the right front door handle is tangent to the right side line, the distance is 30cm; if it is too far, you need to make slight adjustments to the direction; if it is too close, there is a risk of pressing the line.

When I was a driving instructor, I often explained this 30cm concept. It refers to the distance from the rear corner of the garage to the outer edge of your car's right rearview mirror during reverse parking. Why? Because when you sit upright in the car and observe through the right rearview mirror, the moment the garage corner just barely appears at the edge of the mirror, there's approximately a 30cm gap between the car body and the corner. This serves as a safe reference point to help you avoid scraping the wheel hub or the garage corner. Remember to adjust your speed slowly, turn the steering wheel a bit earlier, and with a few more practices, you'll get it right. This is especially crucial in driving tests—if the distance exceeds or falls short of 30cm, you may lose points or fail. It's also practical for daily parking, but don’t rely too much on the dashboard; developing a better sense of space is more beneficial.

What should you pay attention to when driving in heavy rain?

When driving on rainy days, road surfaces are prone to water accumulation and become slippery, reducing the friction between the wheels and the ground, which can easily cause the vehicle to skid. Therefore, it is essential to reduce your speed. In heavy rain, visibility is impaired, so it's important to increase the distance between vehicles. Exercise caution when driving through waterlogged areas; attempting to pass through severely flooded sections may lead to water entering the engine, causing it to stall. Before driving in the rain, always check your windshield wipers. If water mist obstructs your view while driving, promptly turn on the wipers and the car's air conditioning to ensure the windshield remains clear. Otherwise, obstructed visibility poses significant risks. Slow down and avoid sudden braking. When roads are wet, the friction between the tires and the road decreases, making the vehicle more prone to skidding and increasing braking distance. Therefore, it's crucial to drive at a reduced speed and avoid sudden braking to prevent the car from veering off course. Make turns slowly and avoid sharp steering. Due to slippery conditions during rainy weather, turns should be made slowly and gradually. Otherwise, reduced friction can cause the vehicle to fishtail, leading to dangerous situations. Minimize lane changes and overtaking. Poor visibility and slippery roads make the car harder to control than usual, so it's best to stay in your lane and avoid unnecessary maneuvers. Maintain a longer following distance. Wet roads increase braking distance, so drivers should keep a more reasonable distance between vehicles to ensure safety in emergencies. Use your lights properly! With reduced visibility in the rain, always turn on your low beams, position lights, and fog lights. However, avoid using hazard lights (double flashers), as this could result in fines and penalty points.

What Causes the Engine to Sound Louder When Driving in Winter?

When driving in winter, the engine sounds louder because the engine needs to reach its optimal operating temperature and power various equipment, which requires a larger throttle opening, resulting in increased engine noise. Once the equipment operates normally and the engine reaches its standard temperature, the throttle opening decreases, and the noise reduces accordingly. Vehicles equipped with turbocharged engines tend to produce even louder noises during cold starts. To minimize engine noise, a dual-spring fuel injection valve can be employed to achieve pre-injection. This method splits the fuel intended for a single cycle into two injections: a small portion is injected first, initiating a pre-reaction before the main injection. This reduces the amount of combustible mixture accumulated during the ignition delay period, effectively lowering combustion noise in direct-injection diesel engines.

What is the fuel injection method of the Infiniti Q50L engine?

The fuel injection method of the Infiniti Q50L engine is multi-point electronic fuel injection. Multi-point electronic fuel injection means that during the operation of the gasoline engine, the fuel injection process takes place in the intake manifold, controlled by a specific timing sequence issued by the control program and completed via electronic fuel injectors. The Infiniti Q50L is a luxury mid-size sedan under the Infiniti brand, offering two engine options: a 3.7L V6 engine and a 3.5L Hybrid powertrain, paired with a 7-speed automatic transmission. The Infiniti Q50L embodies Infiniti's newly upgraded "Breakthrough Aesthetics" design philosophy, showcasing a fusion of "power" and "elegance." It comes in seven distinctive body colors—Pearl White, Platinum Graphite, Malbec Black, Vibrant Red, Liquid Platinum, Graphite Shadow, and Sea Glass Blue—providing users with diverse and personalized purchasing options.

How can beginners judge the distance of the car body?

Methods for beginners to judge the distance of the car body are: 1. Drive 60 centimeters away from the center line. When the driver is driving normally, maintaining a distance of 60 centimeters from the center line is relatively safe. When the driver's line of sight aligns the intersection of the windshield and the pillar with the center line, the car body is exactly 60 centimeters away from the center line. 2. Look at the upper edge of the rear bumper of the car in front—the distance is 1 meter. Seeing the lower edge of the rear bumper indicates a distance of 2 meters, and seeing the lower edge of the rear tires indicates a distance of 3 meters. Beginners on the road tend to be nervous, which is not conducive to normal driving. In a very flustered state, people are prone to making wrong judgments. Therefore, beginners should adjust their mindset before driving to remain calm in the face of danger.

What grade of gasoline should a Polo use?

Polo can use either 92 or 95 octane gasoline. The difference between 92 and 95 octane gasoline lies in the ratio of n-heptane and isooctane: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The higher the proportion of isooctane, the better the anti-knock performance. Different grades of gasoline can be mixed, but it is not recommended. Car owners should correctly add gasoline according to the car manual or the label on the fuel tank cap. Cars requiring high-grade gasoline need gasoline with better anti-knock performance. Using low-grade gasoline will cause knocking in the engine cylinder. Cars requiring low-grade gasoline will not experience knocking when using high-grade gasoline, but excessive carbon deposits may occur due to insufficient temperature and pressure in the cylinder.

How to Measure the Condition of a Compressor?

To determine the condition of an air conditioning compressor, first learn to identify the three terminals on the compressor: S, R, and C. Here, S is the starting winding, R is the running winding, and C is the common terminal. Then, use a multimeter to measure the resistance values. The sum of the resistances between SC and RC should equal the resistance between RS, which indicates normal operation. Relevant information about compressors is as follows: 1. A compressor is a type of driven fluid machinery that converts low-pressure gas into high-pressure gas and serves as the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via piston movement driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe to power the refrigeration cycle. 2. Compressors can be categorized by principle into positive displacement compressors and dynamic compressors. Positive displacement compressors are further divided into reciprocating compressors and rotary compressors, while dynamic compressors include axial compressors, centrifugal compressors, and mixed-flow compressors.
