  2. Compression ratio - Wikipedia

    en.wikipedia.org/wiki/Compression_ratio

    In piston engines, static compression ratio is determined using the cylinder volume when the piston is at the top and bottom of its travel. The compression ratio is the ratio between the maximum and minimum volume during the compression stage of the power cycle in a piston or Wankel engine.

  3. Leak-down tester - Wikipedia

    en.wikipedia.org/wiki/Leak-down_tester

    Compression tests should normally be done with all spark plugs removed to maximize cranking speed. Cranking compression is a dynamic test of the actual low-speed pumping action, where peak cylinder pressure is measured and stored. A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths.

  4. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. [1] Despite having the dimension of pressure, MEP cannot be measured. [2]

  5. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart).

  6. Octane rating - Wikipedia

    en.wikipedia.org/wiki/Octane_rating

    An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without causing engine knocking.The higher the octane number, the more compression the fuel can withstand before detonating.

    The 700-cc e-REX is tiny, measuring about 16 inches long and 10 inches in diameter and weighing under 90 pounds. ... This effectively alters combustion volume and allows the engine to vary its ...

  8. 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 .

  9. Engine efficiency - Wikipedia

    en.wikipedia.org/wiki/Engine_efficiency

    Engines using the Diesel cycle are usually more efficient, although the Diesel cycle itself is less efficient at equal compression ratios. Since diesel engines use much higher compression ratios (the heat of compression is used to ignite the slow-burning diesel fuel), that higher ratio more than compensates for air pumping losses within the engine.
