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.
SCOPE OF EXPERIMENTATIONS:
· To determine specific fuel
consumption.
· To determine Brake Horse
Power.
· To determine mechanical
efficiency.
· To determine Brake Thermal
Efficiency.
· To determine volumetric
efficiency measurement.
· To determine indicated
thermal efficiency.
UTILITIES REQUIREMENTS:
· Electric Supply-Single
Phase, 220 V, 5 Amp.
· Continuous Water Supply-10
LPM Approx.
· Fuel-10 Ltrs.
· Floor Area-3m X 2m
· Tachometer-For RPM
measurement
TECHNICAL DETAILS:
· Type of Engine-Four
cylinder, four stroke engine, vertical water cooled, self start, diesel
engine.
· Type of Loading
o TD-106A – Electric Brake
Dynamometer
§ The engine is coupled with electrical
alternator with resistance loading arrangement. Digital voltmeter and digital
ammeter is provided.
o TD-106B –Hydraulic Brake
Dynamometer
§ It consist 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.
OPTIONAL :
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 |
