Compression testing measures the ability of an engine to compress its air-fuel mixture properly. This compression is crucial for the engine to operate efficiently and effectively. When you pull the starter rope on a small engine, the piston moves down the cylinder, allowing air and fuel to enter the combustion chamber. As the piston moves back up, it compresses this mixture. The higher the compression, the more power the engine can produce.

Battery technology is a core component of any new energy car, as it directly affects the vehicle’s performance and lifespan. In traditional internal combustion engine cars, engines and transmissions wear out long before hitting 1 million miles. In contrast, the electric motors in new energy cars are simpler and more durable. The limiting factor has always been the battery. Recent developments, such as solid-state batteries and advanced lithium-ion chemistries, have dramatically increased the number of charge cycles a battery can endure, bringing the possibility of a 1 million-mile battery closer to reality.

The last number, 20, indicates the diameter of the wheel rim in inches that the tire is designed to fit. In this case, the tire fits a 20-inch wheel. It is essential to pair the correct size tire with the appropriate rim to ensure safety and optimal performance. A larger wheel diameter can impact the vehicle's handling characteristics, as it often leads to a lower sidewall height and a sportier ride. However, it can also lead to a harsher ride due to less sidewall flex.
