Multi Cylinder Four Stroke Petrol Engine Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-TELE-9431
Jlab Export is a leading Multi Cylinder Four Stroke Petrol Engine Test Rig Manufacturer,and suppliers in India
Heat balance and the Morse test are the two main experiments on this multi cylinder, four stroke petrol engine rig. It is a self-contained setup for teaching spark ignition engine principles. The rig is instrumented for brake power, indicated power by the Morse test arrangement, fuel consumption, air intake and the heat rejected to the cooling water jacket.

Heat Balance and Morse Test Experiments
For a heat balance, students hold the engine at a steady load and speed. They record brake power, fuel flow, and the jacket water flow with its inlet and outlet temperatures. Heat supplied is the fuel mass flow times its calorific value, which the class can find for its own fuel sample with a Digital Bomb Calorimeter.
Heat to the jacket water is its mass flow times the specific heat of water times the temperature rise. Brake power, jacket heat and the remainder, which covers exhaust heat and unmeasured losses, are then set out against the heat supplied. In the Morse test, each cylinder is cut out in turn and the speed restored. A Gas Exhaust Analyzer can log exhaust CO and HC at each load in the same session.
Frequently Asked Questions
What is a heat balance sheet?
It is a table that splits the heat released by the fuel into brake power, heat carried off by the cooling water and the rest. The rest includes exhaust heat and losses not measured. Each part is shown in kW and as a percentage of the heat supplied.
How is indicated power found without an indicator diagram?
By the Morse test. One cylinder at a time is cut out and the dynamometer load reduced until the speed is back to its set value. The fall in brake power is the indicated power of that cylinder, and the sum over all cylinders gives the engine IP.
Why measure the calorific value of the fuel?
Heat supplied, and so brake thermal efficiency and the whole heat balance, rests on fuel mass flow times calorific value. A value measured for the actual fuel batch gives a closer balance than a textbook figure.
How does this rig compare with the four cylinder Morse test rig?
Both run four stroke petrol engines and support the Morse test. This rig is also instrumented for heat rejected to the water jacket and a full heat balance test. The Four Stroke Four Cylinder Petrol Engine Test Rig With Morse Test has a 12 V starting battery and a burette fuel system.
