Indicated Horsepower (IHP) a) The total amount of power developed by an engine. It’s easy to assume from a casual glance at ads or spec sheets that even quite ordinary American family sedans of the sixties were overwhelmingly powerful, with 300 horsepower or more, and yet by 1975, many of those same cars were down to 150 hp or less. The power developed within a cylinder can be calculated by measuring the imep and the engine speed. ihp: Indicated horsepower or gross horsepower (academic capability of the engine) minus frictional losses within the engine (bearings drag, rod and crankshaft windage losses, oil film drag, etc. This work, W, is called the indicated work and will be represented as W i. Indicated horsepower (ihp) Indicated horsepower is the theoretical power of a reciprocating engine assuming that it is completely efficient in converting the energy contained in the expanding gases in the cylinders. kW to BHP conversion calculator; How to convert kW to BHP This mean height, when multiplied by the spring scale of the indicator mechanism, gives the indicated mean effective pressures for the cylinder. Torque A fluidic or electrical coupling transmits forces between rotor and stator. Theoretical horsepower required to compress one cubic foot of free air (atmospheric pressure) for single-staged, two-staged and three-staged compressors are indicated in the diagram below. Indicated horsepower (ihp) is the theoretical power of a reciprocating engine if it is completely frictionless in converting the expanding gas energy (piston pressure × displacement) in the cylinders. If you already know the measured brake horsepower or brake torque, you can calculate the MEP required to produce it. Abbreviation: ihp, IHP See more. 35 (b)The brake horse power is (kW)  Manufacturers can often pick and choose between power units, so here's a low- down of what they all equate to. But unlike later measures such as shaft horsepower (shp) and brake horsepower (bhp), it did not take into account power losses due to the machinery internal frictional losses, such as a piston sliding within the Effective horsepower definition is - the net horsepower required to move a vehicle or boat that is the part of the total propelling engine horsepower that remains after deducting losses due to engine friction and propeller and other inefficiencies. 341 hp. .
