Water Cooled, Multi-Cylinder, 4-Stroke, Diesel Engine Testrig — MOE Lab Tender Details

Water Cooled, Multi-Cylinder, 4-Stroke, Diesel Engine Testrig for Thermodynamics Lab Equipments

The test-rig should consist of the following:  
Test Stand (Control and Load unit):  
• Computer Controlled, Control and Load Unit for 4-Cylinder,4-Stroke Diesel Engine
with a maximum power output of 75 kW
• Test Stand with wheels for mobility with proper vibration control measures
• Schematic diagram of the complete system on the front panel  
• Eddy current brake.  
• Force transmission from the engine to the brake unit by means of a coupling
(universal joint/leather pads).  
• Air intake duct with a calibrated anemometer for measurement of air velocity
• Quietening vessel for intake air.  
• Potentiometer for continuous adjustment of braking torque and speed.  
• Sensors for measurement and display of Engine Load, Air Temperature, Air intake
Quantity, Speed, Fuel Consumption, Oil pressure, Exhaust Gas Temperature, Oil
Temperature and Cooling Water Temperature.
Thermostat valve between radiator and engine whose temperature range (20- 170oC) can be varied to test effect of
cooling water temperature on engine performance.  
• The unit should be Computer Controlled i.e. commands for operation of unit should
be given from computer.
Water Cooled Four Stroke Four Cylinder Diesel Engine:  
 
• Power output: minimum 20 kW at 3000 rpm and maximum75 kW at 3000 rpm
• Compression ratio (minimum): 20:1  
• Desirable Additional Feature: to run on Biodiesel and Hybrid fuels.   
Electronic Engine Indicating System:
• Cylinder pressure indication system for internal combustion engine  
• Chronological representation of pressure curve against the crank angle in P-θ
diagram to determine the maximum pressure and to monitor the ignition point and
the pressure increase.  
• Representation of pressure curve against the standardized piston capacity in P-V
diagram to determine the indicated power output.  
• System consisting of measuring amplifier, TDC sensor with suitable software e.g.
