What is a Compressor Ratio?

How to lower the compression ratio of an engine

An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2 . At the beginning of the compression process, air is at 95 kPa and 27^∘ C. Accounting for the variation of specific heats with temperature, determine (a) the temperature after the heat-addition process, (b) the thermal efficiency, and (c) the mean effective pressure. | Numerade

Compression Ratio defines how much air a compressor squeezes in a single stroke. A higher ratio delivers greater pressure for demanding applications and efficient performance. Understanding it helps you choose the right compressor for your needs.

The compression ratio of an ideal dual cycle is 14 . Air is at 100 kPa and 300  K at the beginning of the compression process and at 2200  K at the end of the heat-addition process. Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4  kJ / kg. Assuming variable specific heats for air, determine (a) the fraction of heat transferred at constant volume and (b) the thermal efficiency of the cycle. | Numerade
