Methods for testing the quality of automotive shock absorbers are as follows: 1. Press down hard on the bumper and then release it. If the car bounces 2~3 times, it indicates that the shock absorber is working well. 2. When the car is moving slowly and emergency braking is applied, if the car vibrates violently, it indicates a problem with the shock absorber. 3. Remove the shock absorber and stand it upright, then clamp the lower connecting ring with a bench vise. Pull and press the shock absorber rod several times with force. There should be a stable resistance during this process, and the resistance when pulling up (recovery) should be greater than when pressing down. If the resistance is unstable or there is no resistance, it may indicate that the shock absorber is low on oil or the valve components are damaged, and repair or replacement of parts is necessary.

What is the fuel consumption of the Changan CS75?

The manual transmission model of the Changan CS75 has a fuel consumption of 7.3 liters per 100 kilometers, while the automatic transmission model consumes 8.4 liters per 100 kilometers. Below is some related information about the Changan CS75: 1. Introduction to the Changan CS75: The Changan CS75 is a compact SUV under the Changan brand, and all models are equipped with a 1.5-liter turbocharged engine. The dimensions of the Changan CS75 are 4650 mm in length, 1850 mm in width, and 1705 mm in height, with a wheelbase of 2700 mm. 2. Improving fuel economy: Maintain tire pressure at the normal level, as low tire pressure increases the car's resistance, thereby increasing fuel consumption. The fuel consumption is reduced by an average of 3.3% when the tire pressure meets the required standards compared to insufficient tire pressure.

What is the standard load capacity of a 13-meter trailer in tons?

According to national regulations, the standard maximum load capacity for a 13-meter semi-trailer is generally 34 tons. Below is relevant information: 1. Characteristics of semi-trailers: A semi-trailer has its axles positioned behind the vehicle's center (when evenly loaded) and is equipped with a coupling device that transmits horizontal and vertical forces to the tractor. It is a heavy-duty transport vehicle connected to the semi-tractor via a kingpin. The national standard allows for a total weight of 55 tons including the trailer's own weight, but the trailer's load-bearing capacity can reach up to 200 tons. 2. Classification of semi-trailers: Semi-trailers are typically three-axle vehicles, categorized into types such as 11-meter warehouse-barrier trailers, 13-meter warehouse-barrier trailers, and low-bed semi-trailers. Vehicles with similar load capacity and dimensions as standard high-barrier trailers but 15% lighter in weight are classified as light-duty. 3. Load capacities for different models: A 6.8-ton self-weight vehicle can haul approximately 40 tons, while a 7.2-ton self-weight vehicle can haul around 50 tons.

How to Handle Failure in Reverse Parking?

There are three key words for reverse parking: slow, accurate, adjust; reversing must be slow, and steering should only be turned when reaching the designated point. However, since stopping midway is not allowed now, it's necessary to turn the steering wheel a bit earlier. When turning the steering wheel, adhere to the principle of fast steering but slow speed; before completing the turn, press the clutch to reduce speed. Relevant information about the driver's license test is as follows: 1. Introduction: The driver's test is a qualification examination organized by the Vehicle Management Office of the Public Security Bureau. Only by passing the driver's test can one obtain a driver's license and legally operate motor vehicles. 2. Content: The motor vehicle driver's test is divided into the road traffic safety laws, regulations, and related knowledge test (also known as the 'theoretical test', referred to as 'Subject 1'), the field driving skills test (commonly known as 'pole test', referred to as 'Subject 2'), and the road driving skills and safe civilized driving common sense test (commonly known as 'road test', referred to as 'Subject 3'). The test content and passing standards are uniform nationwide, with corresponding test items specified according to different types of vehicles eligible for driving.

What to Do When the Car Alarm Keeps Going Off?

The car alarm keeps going off due to an overly sensitive alarm, faulty door contact switch, or excessively high sensitivity of the anti-theft sensor. Here are some explanations: 1. Components: including switches, pressure sensors, and motion detectors, the alarm can emit various sounds and activate alarm devices (such as horns, headlights, or sirens). 2. Reasons for the alarm: (1) Overly sensitive alarm: The alarm is too sensitive and needs slight adjustment. (2) Faulty door contact switch: A faulty door contact switch can also trigger the alarm, requiring repair at a service point. (3) Excessively high sensitivity of the anti-theft sensor: The anti-theft sensor's sensitivity is too high and can be adjusted.

What is transmission oil?

Automobile transmission oil can be broadly divided into two types: one is automatic transmission fluid (ATF), and the other is manual transmission oil. Here is a partial introduction: 1. Transmission oil: Transmission oil is a lubricant used to keep the gear system clean, ensuring the normal operation of the transmission and extending the service life of the transmission device. 2. Automatic transmission fluid: Abbreviated as ATF (Automatic-Transmission-Fluid), it is specifically designed for automatic transmissions. Under normal driving conditions, automatic transmission fluid is typically replaced every 120,000 kilometers, and under harsh driving conditions, it is replaced every 60,000 kilometers. 3. Manual transmission oil: Generally referred to as gear oil, gear oil is classified into five grades (GL-1 to GL-5). GL-1 to GL-3 have lower performance requirements. GL-4 is used for lubrication under conditions of high-speed low-torque and low-speed high-torque, such as in automobile hypoid gear drive shafts and manual transmissions. GL-5 has the highest performance level and is used for lubrication in hypoid gear drive shafts and manual transmissions under severe operating conditions with high impact loads. Under normal driving conditions, manual transmission gear oil is generally replaced every 2 years or 60,000 kilometers.

Are Car Covers Useful?

Car covers are quite useful. Firstly, they provide a certain degree of protection for the car's paint, especially during winter in northeastern regions where snow and frost frequently accumulate on the vehicle. Over time, this can cause varying degrees of damage to the car's body, and using a car cover can effectively prevent these issues. Methods to deal with scratches on the car are as follows: 1. Hairline scratches: These can usually be removed by polishing or applying a rubbing compound. A simple wipe is often enough to make the hairline scratches disappear. 2. Moderate to deep scratches: These cannot be fixed by rubbing. For small dents not exceeding 5mm, filling with putty to level the surface followed by touch-up painting is recommended.
