brake mean effective pressure
1brake mean effective pressure — A measure of mean effective pressure in a cylinder of a reciprocating engine. It is the average in excess of ambient pressure inside the cylinder during the power stroke. It is measured in pounds per square inch (psi), kilopascals (kPa), or bars… …
2brake mean effective pressure — noun the average (mean) pressure which, if imposed on the pistons uniformly from the top to the bottom of each power stroke, would produce the measured (brake) power output. Syn: BMEP …
3brake mean effective pressure — (BMEP) The average pressure in the cylinders of an engine divided by its mechanical efficiency, i.e., the ratio of the power actually delivered at an output shaft to the power developed in the cylinders. It is used as an indication of torque …
4Mean effective pressure — The mean effective pressure is a quantity related to the operation of an reciprocating engine and is a valuable measure of an engine s capacity to do work that is independent of engine displacement[1]. When quoted as an indicated mean effective… …
5mean effective pressure: (MEP) — The average pressure of the burning fuel on the power stroke subtracted by the average pressure on the other three strokes. Pressure is in pounds per square inch. Average pressure on a surface when a changing pressure condition exists. Also see… …
6friction mean effective pressure — That part of the indicated mean effective pressure (IMEP) used to overcome internal friction in a combustion chamber of a reciprocating engine. The difference between the IMEP and the brake mean effective pressure (BMEP) is the FMEP. The FMEP and …
7indicated mean effective pressure — The average pressure produced in the combustion chamber during the operating cycle. It is an expression of the theoretical, frictionless power known as indicated horsepower. In addition to completely disregarding power lost to friction, indicated …
8effective pressure — See brake mean effective pressure indicated mean effective pressure mean effective pressure …
9pressure — [1] The force due to the weight of a substance exerted over the area the substance occupies. In metric measure, it is the force acting on each square metre. To calculate pressure, divide the force (in newtons) by the area (in square metres). It… …
10brake horsepower — The power delivered to the propeller shaft (main drive or main output) of an aircraft engine. It is the difference between the horsepower delivered by the engine and that consumed by friction. The actual horsepower received by the propeller of an …
