Experiments Performed
Determination of Brake Power
The dynamometer applies a controlled load to the diesel engine. The measured engine torque and rotational speed are used to calculate brake power.
Determination of Fuel Consumption
A suitable fuel-measuring arrangement allows the quantity of diesel consumed during a measured time interval to be determined.
Determination of Specific Fuel Consumption
The measured fuel-consumption rate is compared with the brake-power output to determine brake specific fuel consumption.
Determination of Mechanical Efficiency
The experimental setup can be used to study and determine the mechanical efficiency of the engine using the appropriate test method and measured performance parameters.
Working Principle
Four-Stroke Diesel Cycle
The engine operates according to the four-stroke compression-ignition cycle:
- Suction Stroke – Fresh air is drawn into the cylinder.
- Compression Stroke – Air is compressed to a high pressure and temperature.
- Power Stroke – Diesel fuel is injected into the compressed hot air, resulting in combustion and useful power generation.
- Exhaust Stroke – Combustion products are expelled from the cylinder.
In a four-cylinder engine, the cylinders operate according to a defined firing sequence, providing smoother and more continuous mechanical output.
Dynamometer Loading System
Controlled Load Application
The dynamometer is mechanically coupled to the engine output shaft and absorbs the power produced by the engine.
By changing the dynamometer load, the engine can be tested at different operating conditions.
The system enables measurement of the resisting torque produced by the dynamometer. Combined with engine RPM, this measurement allows brake power to be determined.
Instrumentation & Control Panel
Centralized Measurement
The test rig incorporates an instrumentation panel for convenient monitoring of the engine and experimental parameters.
Depending on the supplied configuration, the panel can accommodate:
- Digital temperature indicators
- Engine speed indication
- Load measurement
- Fuel-consumption measurement
- Control switches
- Dynamometer controls
- Electrical indicators
- Safety controls
Fuel Consumption Measurement
Fuel Measuring Arrangement
A suitable fuel-measuring system is provided for measuring diesel consumption.
A known quantity or volume of fuel is consumed while the corresponding time is measured. The resulting data can be converted into the required fuel-consumption rate.
This value can subsequently be used for calculating specific fuel consumption and other performance parameters.
Performance Parameters
Brake Power
Brake power represents the useful mechanical output available at the engine shaft.
Engine Torque
Torque represents the turning force developed by the engine against the dynamometer load.
Fuel Consumption
Fuel consumption represents the quantity of diesel consumed during a specified operating period.
Brake Specific Fuel Consumption
BSFC indicates the quantity of fuel required to produce a unit of useful brake power.
Mechanical Efficiency
Mechanical efficiency represents the relationship between useful brake power and the power developed within the engine cylinders.
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
Mechanical Efficiency
Mechanical Efficiency = Brake Power / Indicated Power × 100
The exact method for determining indicated power depends on the selected experimental arrangement.
