Description
IC
engines are widely used in automobile, domestic and industrial sector. They are classified according to cycle,
number of cylinders, arrangement of cylinders, fuel used, type of ignition,
valve arrangement, cooling system. Test rigs are used to find out the
performance of an IC engine. It
consists of an IC Engine, dynamometer, fuel measuring, air intake measuring
and various other arrangements.
EXPERIMENTS:
· To determine specific fuel
consumption.
· To determine Brake Horse
Power.
· To determine Brake Thermal
Efficiency.
· To determine volumetric
efficiency measurement.
TECHNICAL DETAILS:
· Type of Engine
o Single cylinder, four stroke,
vertical water cooled, crank start, diesel engine developing
5 HP at 1500 rpm (Kirloskar New)
· Type of Loading
o TD-104A - Rope Brake Dynamometer
§ Rope Brake arrangement with the
brake drum fitted on the engine shaft and provided with cooling water
arrangement and spring balance in Kg units.
o TD-104B - Electric Brake Dynamometer
§ The engine is coupled with
electrical alternator with resistance loading arrangement. Digital voltmeter
and digital ammeter is provided.
o TD-104C - Hydraulic Brake Dynamometer
§ It consists of weighing gear,
control gear, a dead weight in kg unit suitable for testing the engine at
different speeds. The engine and dynamometer are directly coupled on a
substantial base plate.
· Fuel measuring system
o Fuel measuring system consists
of a fuel tank, a burette and a three way cock arrangement.
· Air intake measuring
system
o Air tank fitted with orifice and
water manometer.
· Measurement of Heat
carried
o It consists of inlet outlet
piping with flow control valve, water away by Cooling water meter.
Thermometers are provided to measure the inlet outlet temperature of water.
· The whole setup is well
designed and supported by a good quality painted rigid M.S. Structure.
OPTIONAL:
Exhaust gas calorimeter:
Exhaust gas calorimeter - made of Stainless Steel including the body &
the tubes for cooling water circulation and designed to get maximum
temperature difference. The body of the calorimeter is insulated on all sides
to prevent heat losses due to radiation. Thermometers are provided to measure
the temperature of water and gas |
