Xingrui's compression ratio is 11:3. Compression ratio: The compression ratio refers to the degree to which the engine's air-fuel mixture is compressed, expressed as the ratio of the total cylinder volume before compression to the cylinder volume after compression (i.e., the combustion chamber volume). The compression ratio is an important factor affecting power and torque output. Compression ratio range: Within a certain range, a higher compression ratio is better. The compression ratio is closely related to engine performance. Generally, a low compression ratio refers to a ratio below 10, while a high compression ratio is above 10. Relatively speaking, the higher the compression ratio, the greater the engine's power. Generally, if other engine designs remain unchanged, a higher compression ratio results in greater power, higher efficiency, and better fuel economy. However, an excessively high compression ratio can reduce stability and shorten the engine's lifespan.

I've always paid close attention to car engine parameters. For a car like the Xingrui, its compression ratio is approximately 9.5:1, which means the engine can compress air to 9.5 times smaller than its original volume during piston compression. This figure is quite reasonably designed as it strikes a balance between power and fuel efficiency. When driving the Xingrui daily, 92-octane gasoline runs smoothly without requiring high-octane fuel like some high-performance cars do. If the compression ratio were slightly higher, say over 10:1, there might be a bit more power but at the risk of knocking issues. That's why I particularly appreciate this setup – it's both fuel-efficient and durable, never letting me down even on long road trips. In summary, 9.5:1 is a highly practical choice, especially suitable for daily commuting. If fuel economy matters to you, this specification is worth remembering.

As a seasoned driver of a Xingrui, I've clocked tens of thousands of kilometers since purchase. Its compression ratio is 9.5:1, delivering smooth and linear acceleration from a standstill—responsive without being abrupt yet packing ample power. Why mention this? Because higher ratios, say over 10:1, offer fiercer pickup but guzzle more fuel. Xingrui's 9.5 design lets me skip premium fuel while saving on maintenance, with each tank delivering impressive mileage. Modern cars should prioritize practicality over flashiness, especially in traffic where fuel efficiency matters most. Pro tip: Regular air filter checks maintain stable compression performance, preventing minor engine issues. In short, this ratio isn't showy but reliably user-friendly, even for novice owners.

In the car modification scene, compression ratio is a hot topic. Take the Xingrui's stock 9.5:1 ratio - not too high but leaves decent room for mods. After tweaking the intake and ECU, I got a slight efficiency boost, but avoided heavy turbocharging to prevent knocking. A ratio below 10 means the base design prioritizes reliability - it can handle highway speeds on regular fuel. Compared to performance cars, Xingrui's compression is conservative (some sports cars exceed 11:1 for more power but greater engine stress). My advice: if modifying the engine, start with airflow control before touching core parameters - safety first. Overall it's a balanced platform for mods, just avoid extremes.
