Higher compression ratios in engines typically lead to improved:

Higher compression ratios in engines typically lead to improved combustion and increased power output. This occurs because a higher compression ratio allows the air-fuel mixture to be compressed more tightly before ignition, which enhances the thermal efficiency of the engine. As a result, the fuel burns more completely and with greater intensity, producing more energy and consequently increasing the power output.

Moreover, a higher compression ratio also contributes to an increase in engine efficiency, as it allows for more work to be done from each unit of fuel consumed. This improvement in combustion is vital for performance, especially in scenarios where power demands are high. Hence, the advantages of higher compression ratios manifest primarily through enhanced combustion processes, leading to improved power output in the engine.

In contrast, while a higher compression ratio can influence factors like fuel efficiency and cylinder temperatures, these effects are secondary to the primary outcome of improved combustion and power generation. As for engine weight, there is no direct correlation; higher compression ratios do not necessarily result in changes to engine weight itself.
