Petrol Engine Performance Test Rig
Model Number: MT- 101
The Petrol Engine Performance Test Rig from Micro Technologies is designed for practical study and performance evaluation of a single-cylinder four-stroke petrol engine under different loading conditions. Equipped with a rope brake dynamometer, the setup enables determination of brake power, fuel consumption, specific fuel consumption and brake thermal efficiency. It is suitable for IC engine, automobile, mechanical and thermal engineering laboratories.
Product Specification
The Petrol Engine Performance Test Rig is a complete experimental setup designed to study the operating characteristics and performance of a four-stroke petrol engine.
The setup consists of a single-cylinder four-stroke petrol engine mounted on a rigid supporting frame and coupled to a rope brake dynamometer. The dynamometer provides a simple and effective arrangement for applying measurable mechanical load to the engine.
During experimentation, the engine can be operated at different loading conditions while important parameters such as engine speed, applied load and fuel consumption are observed.
A suitable fuel-measuring arrangement enables users to determine the quantity of petrol consumed during a known time interval. These observations can then be used to calculate important engine performance parameters.
The test rig provides practical understanding of the relationship between engine load, power output, fuel consumption and efficiency.
Its integrated bench-type construction makes the setup suitable for routine experimental work, demonstrations and performance studies.

Experiments Performed
Determination of Brake Power
The rope brake dynamometer applies a controlled mechanical load to the engine. Using the measured load, effective brake radius and engine speed, the brake power developed by the engine can be calculated.
Determination of Fuel Consumption
A measured quantity of fuel is allowed to flow to the engine and the time required for consumption is recorded. This enables the fuel consumption rate to be determined.
Determination of Specific Fuel Consumption
The measured fuel consumption is related to the useful brake power produced by the engine to calculate brake specific fuel consumption.
Determination of Brake Thermal Efficiency
The useful brake-power output is compared with the rate of energy supplied through the fuel to determine the brake thermal efficiency of the engine.
Working Principle
Engine Operation
The petrol engine converts the chemical energy of fuel into mechanical energy through the four-stroke combustion cycle.
The four strokes are:
- Intake Stroke – Air-fuel mixture enters the cylinder.
- Compression Stroke – The mixture is compressed inside the cylinder.
- Power Stroke – Combustion produces pressure that drives the piston.
- Exhaust Stroke – Combustion gases are expelled from the cylinder.
Continuous repetition of these strokes produces rotary mechanical output at the engine shaft.
Rope Brake Dynamometer
Loading Principle
The rope brake dynamometer is used to apply a controlled resisting load to the rotating engine shaft.
A rope is arranged around the brake drum connected to the engine. By adjusting the loading arrangement, the resistance acting against the engine can be varied.
The difference in applied forces produces a braking torque.
Using the torque and rotational speed, the actual mechanical power available at the engine shaft can be determined.
Performance Parameters
Brake Power
Brake power represents the useful mechanical power available at the output shaft of the engine.
Brake Torque
Brake torque represents the turning force produced by the engine under the applied dynamometer load.
Fuel Consumption
Fuel consumption indicates the amount of petrol consumed by the engine during a specified period.
Brake Specific Fuel Consumption
Brake specific fuel consumption indicates the quantity of fuel consumed for producing a unit of brake power.
Brake Thermal Efficiency
Brake thermal efficiency represents how effectively the energy supplied by the fuel is converted into useful mechanical power at the engine shaft.
Typical Performance Calculations
Brake Torque
Brake torque is calculated using the effective dynamometer load and effective brake radius.
Brake Power
Brake power can be determined from:
Brake Power = (2 × π × N × T) / 60
Where:
- N = Engine speed in RPM
- T = Brake torque in N·m
Fuel Consumption Rate
Fuel consumption is calculated using the measured quantity of fuel and the corresponding consumption time.
Brake Specific Fuel Consumption
BSFC = Fuel Consumption Rate / Brake Power
Brake Thermal Efficiency
Brake thermal efficiency is determined by comparing useful brake-power output with the fuel-energy input rate.

Gradual Loading
Load should be applied progressively rather than suddenly to maintain stable engine operation.
Rotating Parts
Hands, loose clothing and tools should be kept away from rotating components while the engine is operating.
Fuel Handling
Petrol should be handled only in a properly ventilated area and kept away from flames, sparks and other ignition sources.
Exhaust Ventilation
Engine exhaust should be safely routed away from the working area with adequate ventilation.
