The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

A running engine produces heat, which expands its metal body, thereby increasing its compression ratio. This is true for ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

The compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel ...

Formula 1 is edging towards its first major dispute of the 2026 era, with a possible engine loophole fuelling tension ...

Reports have surfaced that some manufacturers have asked for clarification because Mercedes and potentially Red Bull Powertrains may have found a way to increase the compression ratio of their ...
