What is the cylinder pressure of a car?

The normal range for a car's cylinder pressure is no less than seven pressures, but not every engine is the same. Japanese cars typically have around 1100 KPa, while European and American cars range from 1200 to 1300 KPa. Modern direct-injection engines tend to have even higher cylinder pressures. The cylinder pressure data varies by vehicle model. Generally, large vehicles (such as Dongfeng 140 and Jiefang 141) have pressures between 6 to 8 kg, while small cars should have pressures above 8 kg to be considered normal. If the pressure is below the normal range, it can indicate an engine fault. Different cars and models have varying cylinder bore and stroke dimensions, resulting in different cylinder pressure data. A simple way to check cylinder pressure is to ensure that all four cylinders have the same pressure. If one cylinder's pressure differs from the others, it indicates that the cylinder is not functioning properly.

What are the benefits of underbody coating?

The benefits of underbody coating lie in its ability to block climatic effects, while the drawback is that it can cause corrosion to the car's underbody. The specific advantages and disadvantages are as follows: The benefits of underbody coating include effectively preventing car rust and premature aging. During the rainy season, it can prevent corrosion, especially in southern regions where there is more rainfall. While driving, acid rain can easily splash onto the underbody, causing corrosion. Installing underbody coating can avoid these unnecessary damages. Underbody coating can effectively protect against road gravel impacts, prevent minor scrapes and friction, guard against corrosion from acids, alkalis, and salts on the underbody metal, prevent loosening of underbody screws, reduce noise transmission while driving to enhance driving tranquility, and block heat transfer from the underbody metal, keeping the cabin warm in winter and cool in summer. The disadvantages of underbody coating are that if low-quality coating is used, it will not protect the car's underbody but instead cause severe damage. During use, it can corrode the underbody and cause other damages to the car. It is important to note that if low-quality underbody coating is used, the car's exhaust pipe will generate high temperatures during operation, which can cause the coating to release toxic substances, severely affecting the car's normal use and the health of the driver and passengers.

Should a flat tire be repaired or replaced?

Tire blowout requires different approaches depending on the situation: 1. Minor damage: If the wheel runs over the curb, causing a nearly 1cm-wide scratch on the central part of the tire sidewall without exposing the cord layer, and only some rubber is lost, there is no need to replace the tire; 2. Tread damage less than 6mm, or if the tread is punctured by nails or other objects with a hole diameter smaller than 6mm, it can still be repaired; 3. Damage larger than 6mm must be replaced, as even after repair, there is no guarantee that the tire won't leak air. Tires are circular elastic rubber products assembled on various vehicles or machinery for rolling contact with the ground. They are usually mounted on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance.

What is the passing score for Subject 2?

The total score for Subject 2 is 100 points, with a passing score of 80 or above. Subject 2 includes five mandatory test items: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves. Not wearing a seatbelt results in a deduction of 100 points (i.e., failure); not closing the car door properly results in a deduction of 100 points; not using the turn signal as required results in a deduction of 10 points (failing to turn on the right turn signal during parallel parking is a common reason for point deductions); stalling once results in a deduction of 10 points (stalling once during reversing into a garage results in a deduction of 100 points); stopping during the test results in a deduction of 100 points. Deduction criteria for reversing into a garage: not following the designated route or sequence results in a deduction of 100 points; not fully reversing into the garage results in a deduction of 100 points; the vehicle body crossing the line results in a deduction of 100 points; stopping during the maneuver results in a deduction of 100 points (including stopping by braking or stopping due to poor clutch control). Deduction criteria for stopping and starting on a slope: not stopping at the designated point results in a deduction of 100 points. After stopping, if the distance between the front bumper and the control line is more than 30 cm but less than 50 cm, 10 points are deducted; if it is more than 50 cm, 100 points are deducted. Rolling backward more than 30 cm after stopping results in a deduction of 100 points; rolling backward less than 30 cm results in a deduction of 10 points. Not turning on the left turn signal when starting results in a deduction of 10 points (failing to turn on the turn signal is a common mistake among test-takers). Driving over the solid edge line of the road results in a deduction of 100 points. If the right front wheel is more than 30 cm from the edge line when stopping, 10 points are deducted. Stopping during the maneuver results in a deduction of 100 points. Taking more than 30 seconds to start results in a deduction of 100 points. Deduction criteria for turning at a right angle and driving through curves: any wheel driving over the edge line of the road results in a deduction of 100 points; stopping during the maneuver results in a deduction of 100 points. Deduction criteria for parallel parking: after the vehicle is parked in the garage, if the body crosses the line, 100 points are deducted (many test-takers misjudge the vehicle length, leading to point deductions). Driving over the lane edge line during the maneuver results in a deduction of 100 points. Not parking within the garage results in a deduction of 100 points. Not turning on the left turn signal when starting results in a deduction of 10 points. Stopping during the maneuver results in a deduction of 100 points.
