STEP 1: Convert Input(s) to Base Unit

Brake Mean Effective Pressure: 4.76 Bar --> 476000 Pascal (Check conversion here)
Piston Area: 0.166 Square Meter --> 0.166 Square Meter No Conversion Required
Stroke of Piston: 600 Millimeter --> 0.6 Meter (Check conversion here)
RPM: 7000 Radian per Second --> 7000 Radian per Second No Conversion Required
Number of Cylinders: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_4b = (BMEP*A*L*(N/2)*N_c)/60 --> (476000*0.166*0.6*(7000/2)*2)/60

Evaluating ... ...

P_4b = 5531120

STEP 3: Convert Result to Output's Unit

5531120 Watt -->5531.12 Kilowatt (Check conversion here)

FINAL ANSWER

5531.12 Kilowatt <-- Brake Power of 4 Stroke

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.
