Multi-Cylinder Petrol Engine Performance Test Rig
Model Number: MT-102
The Multi-Cylinder Petrol Engine Performance Test Rig from Micro Technologies is designed for practical performance evaluation of three-cylinder or four-cylinder four-stroke petrol engines. The setup can be configured with rope brake, eddy current or hydraulic dynamometers and enables determination of brake power, fuel consumption, specific fuel consumption and brake thermal efficiency under different engine loading conditions.
Product Specification
The Multi-Cylinder Petrol Engine Performance Test Rig is a complete experimental setup developed for detailed study of the operating and performance characteristics of multi-cylinder four-stroke petrol engines.
The system can be supplied with a three-cylinder or four-cylinder petrol engine, depending on laboratory requirements. The engine is securely mounted on a rigid base frame and mechanically coupled to a suitable dynamometer.
A major advantage of this test rig is the availability of different loading systems. Depending on the required experiment and configuration, the setup can be supplied with a rope brake dynamometer, eddy current dynamometer or hydraulic dynamometer.
The dynamometer applies a controlled load to the engine, allowing its performance to be evaluated over different operating conditions.
A suitable fuel-consumption measuring arrangement enables the amount of fuel consumed during a measured period to be determined. Combined with speed and load observations, this allows important performance parameters such as brake power, brake specific fuel consumption and brake thermal efficiency to be calculated.
The setup provides a practical platform for studying multi-cylinder petrol-engine performance and understanding the relationship between load, speed, fuel consumption, power output and efficiency.

Experiments Performed
Determination of Brake Power
The dynamometer applies a measurable load to the engine. Engine torque and rotational speed are used to determine the useful brake power available at the output shaft.
Determination of Fuel Consumption
The fuel-measuring system enables the amount of petrol consumed during a known period to be recorded.
Determination of Specific Fuel Consumption
The measured fuel-consumption rate is compared with the brake-power output to calculate brake specific fuel consumption.
Determination of Brake Thermal Efficiency
Brake thermal efficiency is calculated by comparing the useful brake-power output with the rate of energy supplied through the fuel.
Working Principle
Engine Operation
The multi-cylinder petrol engine operates on the four-stroke cycle consisting of:
- Intake
- Compression
- Power
- Exhaust
The cylinders operate in a coordinated firing sequence to provide smoother and more continuous shaft output than a single-cylinder arrangement.
Engine Loading
The dynamometer coupled to the engine absorbs mechanical output and applies a controlled resisting load.
Measurement
At each selected load condition, parameters such as engine speed, load and fuel consumption are measured.
Performance Analysis
The measured values are used to evaluate the engine's power output, fuel economy and thermal performance.

Performance Parameters
Brake Power
Brake power represents the useful mechanical output available at the engine shaft.
Engine Torque
Engine torque represents the turning force produced by the engine against the applied dynamometer load.
Fuel Consumption
Fuel consumption indicates the amount of petrol required to operate the engine over a specified period.
Brake Specific Fuel Consumption
Brake specific fuel consumption indicates the amount of fuel consumed per unit of useful brake-power output.
Brake Thermal Efficiency
Brake thermal efficiency indicates how efficiently the chemical energy supplied through the fuel is converted into useful mechanical power.
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 is determined from the ratio of useful brake-power output to fuel-energy input rate.

Secure Engine Mounting
The engine and dynamometer should be securely fixed to the rigid base to maintain alignment during operation.
Controlled Loading
Dynamometer loading should always be increased gradually and kept within the rated limits of the engine and dynamometer.
Fuel Safety
Petrol should be handled in a properly ventilated area away from flames, sparks and other ignition sources.
Exhaust Management
Engine exhaust must be safely discharged from the laboratory using an appropriate exhaust and ventilation arrangement.
