Webcompression is increased with higher Compression ratio. higher the compression, higher the expansion (during power stroke). more expansion means more power extracted from burning fuel. also the engine with more compression ratio has more stroke travel (distance between TDS & BDS) ‘S’ too.. Crank radius (a)=S/2 . WebIncrease the compression ratio - Higher compression ratios produce more power, up to a point. The more you compress the air/fuel mixture, however, the more likely it is to spontaneously burst into flame (prior to the spark plug igniting it). Higher octane gasolines prevent this sort of early combustion.
