Brake Thermal Efficiency of Diesel Engine Power Plant Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Thermal Efficiency = Brake Power of 4 Stroke/(Fuel Consumption Rate*Calorific Value)
BTE = P_4b/(m_f*CV)
This formula uses 4 Variables

Variables Used

Brake Thermal Efficiency - Brake Thermal Efficiency is defined as the ratio of the net work output of the engine to the energy input from the fuel, expressed as a percentage.
Brake Power of 4 Stroke - (Measured in Watt) - Brake Power of 4 Stroke is the output of the engine at the shaft measured by a dynamometer in a 4 stroke diesel engine.
Fuel Consumption Rate - (Measured in Kilogram per Second) - Fuel Consumption Rate refers to the rate at which fuel is consumed by the engine.
Calorific Value - (Measured in Joule per Kilogram) - Calorific Value is a measure of the amount of energy contained in a unit of fuel. It is a measure of the energy released when the fuel is burned.

STEP 1: Convert Input(s) to Base Unit

Brake Power of 4 Stroke: 5537 Kilowatt --> 5537000 Watt (Check conversion here)
Fuel Consumption Rate: 0.355 Kilogram per Second --> 0.355 Kilogram per Second No Conversion Required
Calorific Value: 42000 Kilojoule per Kilogram --> 42000000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BTE = P_4b/(m_f*CV) --> 5537000/(0.355*42000000)

Evaluating ... ...

BTE = 0.371361502347418

STEP 3: Convert Result to Output's Unit

0.371361502347418 --> No Conversion Required

FINAL ANSWER

0.371361502347418 ≈ 0.371362 <-- Brake Thermal Efficiency

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.
