Compression ratio = { (swept volume + clearance volume) / clearance volume} Swept volume = (π) x (bore radius squared) x (exposed cylinder height). Clearance volume = 0.000cc [ (bore/2)2 x π x deck height x 16.387].

WebJul 3, 2024 · When you see compression ratios in the 6:1 to 7:1 range in a motorcycle engine, you’re likely looking at a very old motorcycle that’s probably a flathead. Ratios of 7:1 up to about 9:1 are generally found in either low-stress motorcycles like cruisers, or older motorcycles with an OHV design. WebOct 22, 2007 · Modern bike engines tend to run compression ratios in the 10:1 to 12:1 region. By way of an example, a standard CBR600RR has a 12:1 compression ratio, while an FW Developments supersport-tuned RR will run at around 15:1.

Compression...what is considered "High Compression"? - Bob

WebJan 11, 2016 · High compression ratios are a result of high condensing pressures, low evaporator pressures, or both. High compression ratios add more work to the compression stroke of the compressor. More work on the compression stroke will cause the heat of compression to increase and the compressor to have a higher discharge temperature. WebTo get the 1.2:1-ratio compressor to register 5-7dB of gain reduction you’d likely have to set the threshold below the level of the quietest portions of the performance, so you’d see gain-reduction happening all the time, but changing comparatively little for different portions of the performance.
