  2. Compression ratio - Wikipedia

    en.wikipedia.org/wiki/Compression_ratio

    For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.

    [1] [2] D The MinCR, minimum compression ratio, for that level. [2] The MinCR constraint is reduced to half its base value for the 4:2:2 and 4:4:4 chroma sampling profiles and is reduced by an additional half for the Intra profiles. [3] The MinCR is reduced to 1/24th of its base value with the High Throughput 4:4:4 16 Intra profile. [3] [4]

  4. Overall pressure ratio - Wikipedia

    en.wikipedia.org/wiki/Overall_pressure_ratio

    In aeronautical engineering, overall pressure ratio, or overall compression ratio, is the amount of times the pressure increases due to ram compression and the work done by the compressor stages. The compressor pressure ratio is the ratio of the stagnation pressures at the front and rear of the compressor of a gas turbine .

  5. Compression artifact - Wikipedia

    en.wikipedia.org/wiki/Compression_artifact

    The most common digital compression artifacts are DCT blocks, caused by the discrete cosine transform (DCT) compression algorithm used in many digital media standards, such as JPEG, MP3, and MPEG video file formats. [1] [2] [3] These compression artifacts appear when heavy compression is applied, [1] and occur often in common digital media ...

  6. Talk:Compression ratio - Wikipedia

    en.wikipedia.org/wiki/Talk:Compression_ratio

    There are several differences, but the main one in practice is that compression ratio is applied to piston engines, pressure ratio to gas turbines. Compression ratio is the cause of the compression, pressure ratio is the result of this compression and increase in pressure. Compression ratio can be calculated easily from the engine's geometry.

  7. Variable compression ratio - Wikipedia

    en.wikipedia.org/wiki/Variable_compression_ratio

    The engine can produce any compression ratio from 8:1 to 14:1. The highest torque is achieved at 8:1, giving high acceleration, while the best gas mileage (fuel efficiency) is achieved at 14:1. The electronic engine controller responds to the pressure on the gas pedal, in real-time, altering the compression ratio seamlessly.

  8. Homogeneous charge compression ignition - Wikipedia

    en.wikipedia.org/wiki/Homogeneous_charge...

    Mazda's Skyactiv-G Generation 2 has a compression ratio of 18:1 to allow the use of HCCI combustion. [39] An engine model called Skyactiv#Skyactiv-X has been announced by Mazda in August 2017 as a major breakthrough in engine technology. [40] Mazda is undertaking research with HCCI with Wankel engines. [41]

  9. Weissman score - Wikipedia

    en.wikipedia.org/wiki/Weissman_score

    The Weissman score is a performance metric for lossless compression applications. It was developed by Tsachy Weissman, a professor at Stanford University, and Vinith Misra, a graduate student, at the request of producers for HBO's television series Silicon Valley, a television show about a fictional tech start-up working on a data compression algorithm.
