  2. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    Indicated mean effective pressure (IMEP, ) - Mean effective pressure calculated from in-cylinder pressure over the complete engine cycle (720° in a four-stroke, 360° in a two-stroke). IMEP may be determined by planimetering the area in an engine's pV-diagram .

  3. Toyota RI engine - Wikipedia

    en.wikipedia.org/wiki/Toyota_RI_engine

    The Toyota RI is a family of prototype four-stroke 2.0-litre single-turbocharged inline-4 racing engines, developed and produced by Toyota, for the Super GT series and Super Formula under the Nippon Race Engine framework. The RI engine is fully custom-built.

  4. Indicator diagram - Wikipedia

    en.wikipedia.org/wiki/Indicator_diagram

    An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...

  5. Overall pressure ratio - Wikipedia

    en.wikipedia.org/wiki/Overall_pressure_ratio

    As can be seen in the formula for maximum theoretical thermal efficiency in an ideal Brayton cycle engine, a high pressure ratio leads to higher thermal efficiency: = where PR is the pressure ratio and gamma the heat capacity ratio of the fluid, 1.4 for air.

  6. Otto cycle - Wikipedia

    en.wikipedia.org/wiki/Otto_cycle

    The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.

  7. Compressor map - Wikipedia

    en.wikipedia.org/wiki/Compressor_map

    A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
