IMEP Full Form, What does IMEP stand for?

The Full form of IMEP

IMEP Full Form – The full form of the IMEP refers to Indicated Mean Effective Pressure, which is the average of the total pressure produced during the operation cycle inside the combustion chamber. The IMEP is the combined brake mean effective pressure (BMEP) and friction mean effective pressure (FMEP), which is independent of the engine’s speed, displacement, and the number of cylinders in the automobile. This cylinder pressure is used for calculating the work done by the gas on the piston, and the engine’s efficiency during the cyclic energy release time period.

To measure the Indicated Mean Effective Pressure effectively, the determination of transducer properties, positioning of top dead center, crank angle, mounting location, and stability of transducer sensitivity is significant. The work done by the engine irrespective of its own displacement is a valuable measure that is related to the indicated mean effective pressure. During the power stroke by the engine, the pressure which is theoretically assumed to be acting upon the piston is referred to as the indicated mean effective pressure. 

The IMEP is used to calculating the volumetric capacity of the engine, its design and torque produced. The IMEP is the total sum of brake mean effective pressure and Friction mean effective pressure and thus taking into account the significance of IMEP, the mechanical efficiency of the engine can be calculated easily. A 2-stroke combustion engine produces more torque than a 4-stroke internal combustion engine at the same brake mean effective pressure, therefore it produces more thermal and mechanical stress on the components of the engine.
