Dynamic compression ratio and pump gas
WebSince no compression builds until after the intake valve closes, it's the corrected compression ratio that gives the best indication of how pump gas friendly your motor will be. Premium pump gas in the U.S. will generally tolerate corrected compression ratios of somewhere between 8.8:1 and 9.3:1. http://www.hammerperf.com/ttcompression.shtml

WebApr 4, 2005 · I'm reluctant to draw a line to the limits of compression vs octane. A long time ago 6:1 was considered High Compression. I was talking the other day to Scott at King motorsports and he claims to have street Honda's running 12:1 with 93 octane. These have VTEC so the DCR is variable as well. WebApr 14, 2024 · Interestingly, the segregation of gas mixtures in dynamic systems, i.e., pipelines, was recently reported for flowing H 2-CH 4 gas mixtures under specific conditions. Another recently published paper by Alkhatib et al. [ 25 ] also noted that the thermodynamic properties of H 2 and CH 4 mixtures are well studied, though under a small range of ...
WebDynamic Compression Ratio (DCR) is an important concept in high performance engines. Determining what the compression ratio is after the intake valve closes provides valuable information about how the engine will perform with a particular cam and octane. WebJul 14, 2006 · Cranking compression is kind of like a Dynamic Compression indicator. Small cam and low compression can give the same cranking compression as a large cam and high compression. HOWEVER..... what gets overlooked is that static compression ratio STILL MATTERS. It still affects your PEAK cylinder pressure (engine running).
