Brake Mean Effective Pressure of 4S Engines given Brake power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Mean Effective Pressure = (2*Brake Power)/(Stroke Length*Area of Cross Section*(Engine Speed))
P_mb = (2*BP)/(L*A_c*(N))
This formula uses 5 Variables

Variables Used

Brake Mean Effective Pressure - (Measured in Pascal) - Brake Mean Effective Pressure is a calculation of the engine cylinder pressure that would give the measured brake horsepower.
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Stroke Length - (Measured in Meter) - Stroke Length is the distance travelled by the piston during each cycle.
Area of Cross Section - (Measured in Square Meter) - Area of Cross Section is the enclosed surface area, product of length and breadth.
Engine Speed - (Measured in Radian per Second) - Engine Speed is the speed at which the crankshaft of the engine rotates.

STEP 1: Convert Input(s) to Base Unit

Brake Power: 1.93 Watt --> 1.93 Watt No Conversion Required
Stroke Length: 8.8 Centimeter --> 0.088 Meter (Check conversion here)
Area of Cross Section: 30 Square Centimeter --> 0.003 Square Meter (Check conversion here)
Engine Speed: 400 Revolution per Minute --> 41.8879020457308 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_mb = (2*BP)/(L*A_c*(N)) --> (2*1.93)/(0.088*0.003*(41.8879020457308))

Evaluating ... ...

P_mb = 349.055727480682

STEP 3: Convert Result to Output's Unit

349.055727480682 Pascal --> No Conversion Required

FINAL ANSWER

349.055727480682 ≈ 349.0557 Pascal <-- Brake Mean Effective Pressure

What is brake mean effective pressure?

The torque generated at the crankshaft is called the Brake Torque. The Mean effective pressure calculated from the Brake torque is called the Brake Mean Effective Pressure.

What is the difference between 4S and 2S engines?

The main difference between a 4-stroke engine and a 2-stroke engine is that a 4-stroke engine goes through four stages, or two complete revolutions, to complete one power stroke, while a 2-stroke engine goes through 2 stages, or one complete revolution, to complete one power stroke.
