Product Specification Sheet
Diesel Engine Performance Test Rig
Model Number: MT- 104A
The Diesel Engine Performance Test Rig from Micro Technologies is designed for practical testing and performance analysis of a single-cylinder four-stroke diesel engine. The setup allows users to study engine behaviour under different loading conditions and determine important parameters including brake power, fuel consumption, specific fuel consumption and brake thermal efficiency.
Product Specification
The Diesel Engine Performance Test Rig is a complete experimental system developed for studying the operating characteristics and performance of a single-cylinder four-stroke compression-ignition engine.
The diesel engine is mounted securely on a strong base frame and mechanically coupled to a suitable dynamometer loading system. The dynamometer enables a controlled load to be applied to the engine so its performance can be evaluated at different operating conditions.
During testing, important observations such as engine speed, applied load and fuel consumption can be recorded. These measured values are then used to calculate engine power output, fuel economy and thermal performance.
A suitable fuel-measuring arrangement allows the quantity of diesel consumed during a known time interval to be measured. This information is useful for determining fuel consumption rate and brake specific fuel consumption.
By combining fuel consumption with the useful power developed at the engine shaft, users can also determine brake thermal efficiency.
The complete setup provides a practical platform for studying diesel-engine characteristics and understanding the relationship between load, speed, power output, fuel consumption and efficiency.

Experiments Performed
Determination of Brake Power
The dynamometer applies a controlled load to the engine. Using measured engine speed and torque, the useful brake power available at the output shaft can be calculated.
Determination of Fuel Consumption
The fuel-measuring arrangement is used to measure the quantity of diesel consumed by the engine over a known period.
Determination of Specific Fuel Consumption
The measured fuel consumption is related to the useful brake-power output to determine brake specific fuel consumption.
Determination of Brake Thermal Efficiency
Brake thermal efficiency is determined by comparing useful engine power output with the rate of energy supplied through the diesel fuel.
Working Principle
Four-Stroke Diesel Engine Cycle
The diesel engine operates through four basic strokes:
- Suction Stroke – Air enters the engine cylinder.
- Compression Stroke – The air is compressed, increasing its pressure and temperature.
- Power Stroke – Diesel fuel is injected into the hot compressed air, where combustion produces the power stroke.
- Exhaust Stroke – Combustion gases are discharged from the cylinder.
This cycle repeats continuously to produce mechanical power at the engine shaft.
Dynamometer Loading System
Controlled Engine Loading
The dynamometer absorbs mechanical output from the diesel engine and applies a measurable resisting torque.
By changing the dynamometer load, the engine can be operated at different load conditions while performance parameters are recorded.
This allows users to compare engine behaviour from lower load to higher load conditions within the rated operating range.
Performance Parameters
Brake Power
Brake power represents the useful mechanical power available at the output shaft of the diesel engine.
Engine Torque
Torque indicates the turning force produced by the engine against the dynamometer load.
Fuel Consumption
Fuel consumption represents the quantity of diesel used during a specified period of engine operation.
Brake Specific Fuel Consumption
Brake specific fuel consumption indicates the amount of fuel required to generate a unit of useful brake power.
Brake Thermal Efficiency
Brake thermal efficiency indicates how effectively the chemical energy of diesel fuel is converted into useful mechanical output.
Typical Calculations
Brake Power
Brake Power = (2 × π × N × T) / 60
Where:
- N = Engine speed in RPM
- T = Engine torque in N·m
Brake Specific Fuel Consumption
BSFC = Fuel Consumption Rate / Brake Power
Brake Thermal Efficiency
Brake Thermal Efficiency = Brake Power / Fuel Energy Input
The fuel-energy input depends on the fuel-consumption rate and calorific value of the diesel fuel.
