Is it necessary to apply undercoating to a car?

1 Answers

Applying undercoating to a car is necessary as it provides better protection for the vehicle's chassis and offers some sound insulation. Undercoating is not actually armor, but rather a high-tech adhesive rubber asphalt coating applied to the car's chassis, typically 2mm to 4mm thick. The benefits of undercoating include: 1. Anti-corrosion: It effectively resists corrosion from sewage, oil stains, and other contaminants on chassis components, extending their service life; 2. Anti-friction: Undercoating can withstand minor undercarriage scrapes and reduce the impact and friction from small stones and debris kicked up during high-speed driving; 3. Noise reduction: Due to its rubber asphalt composition and certain thickness, undercoating can to some extent isolate noise transmitted from the chassis.

What is the Principle of Air Suspension?

Air suspension works by using an air compressor to generate compressed air, which is then used to adjust the vehicle's ground clearance. Typically, vehicles equipped with air suspension have ground clearance sensors near the front and rear wheels. Based on the output signals from these sensors, the vehicle's computer detects changes in the vehicle's height and controls the air compressor and exhaust valves to automatically compress or extend the springs, thereby achieving a damping effect. Air suspension mainly consists of a control computer, intake ports, exhaust ports, pneumatic front and rear shock absorbers, and an air distributor. A high-quality SUV must combine the comfort of a sedan with the off-road capability of an SUV, and an air suspension system is an ideal choice to achieve this goal.

What is the reason for failing to climb the slope in Subject 2 of the driving test?

Failing to climb the slope is a common issue during the test. Here are the detailed explanations: 1. Half-clutch technique: When starting, the speed difference between the engine's flywheel and the clutch plate is relatively large. If the clutch is engaged suddenly at this point, the engine will stall. When using the half-clutch technique, it is also essential to control the timing carefully and avoid keeping the clutch in the half-clutch state for too long, as this will accelerate the wear of the clutch plate. 2. Clutch plate wear: The clutch plate is a wear-prone component, and it will wear out as the mileage increases. If the clutch plate wears to a certain extent, it needs to be replaced.
