Brake Mean Effective Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Mean Effective Pressure = Mechanical Efficiency*Indicated Mean Effective Pressure
BMEP = η_m*IMEP
This formula uses 3 Variables

Variables Used

Brake Mean Effective Pressure - (Measured in Pascal) - Brake Mean Effective Pressure is a measure of the average pressure exerted on the piston during the power stroke, and is calculated by dividing net work output of engine by the displacement volume.
Mechanical Efficiency - Mechanical Efficiency is measure of the effectiveness with which a mechanical system performs.
Indicated Mean Effective Pressure - (Measured in Pascal) - Indicated Mean Effective Pressure can be thought of as the pressure that persists in the cylinder during the entirety of one cycle of the engine.

STEP 1: Convert Input(s) to Base Unit

Mechanical Efficiency: 0.733 --> No Conversion Required
Indicated Mean Effective Pressure: 6.5 Bar --> 650000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BMEP = η_m*IMEP --> 0.733*650000

Evaluating ... ...

BMEP = 476450

What is a Diesel Engine Power Plant?

A Diesel Engine Power Plant(also known as Stand-by power station) uses a diesel engine as prime mover for the generation of electrical energy. This power station is generally compact and thus can be located where it is actually required. This kind of power station can be used to produce limited amounts of electrical energy.

What are the types of Diesel Engines?

Diesel engines can be classified into two-stroke and four-stroke engines, as well as inline and V-type engines. Two-stroke engines are simpler and more compact than four-stroke engines, but are less fuel efficient and emit more pollutants. Four-stroke engines are more complex but offer better fuel efficiency and lower emissions. Inline engines are simpler and more compact than V-type engines, but V-type engines are smoother and more powerful.
