Code: TIE0001
Single Cylinder Two Stroke Petrol Engine Test Rig.
Introduction
The test rig is designed to provide self-contained facility for teaching
spark Ignition engine principles. The unit is instrumented so that the
following experiments can be carried out.
1). BHP MEASUREMENT
2). BRAKE THERMAL EFFICIENCY
3). FUEL CONSUMPTION MEASUEMENT
4). AIR INTAKE MEASUREMENT
The Engine Test Rig Facilitate To Evaluate The Following:
1). Performance at various throttle position
2). BHP measurement from no load to full load
Description
Three main components from main parts of the test rig. Welded steel base
plate, complete with Mechanical Brake or A.C. Alternator or D.C.
Generator or Eddy Current Dynamometer, Drive coupling and with safety
guard, anti vibration mounting.
Resistance loading (Resistance bank) with selector switches to load the
engine from no load to full load (Only for A.C. Alternator & D.C.
Generator) Panel board positioned over the base plate consisting of fuel
system with flow measurement by burette, air flow measurement system,
temperature indicator.
Dynamometer (As Applicable)
1). The dynamometer used is a mechanical Brake capable of absorbing a maximum load of 2.5 HP at a speed to 2800 RPM.
2). The Loading device use din an AC alternator of
matching capacity to load the engine up to 2.5 HP at 2800 RPM along with
Resistance loading arrangement for alternator.
3). The Loading device used is DC Generator of
matching capacity to load the engine up to 2.5 HP at 2800 RPM along with
Resistance loading arrangement provided with selector switches.
4). The loading device used is and Eddy Current Dynamometer of matching capacity to load the engine up to 2.5 HP at 2800 RPM.
Instrumentation (as applicable)
The following instrumentation is provided.
1). 'U' tube manometer for air flow rate
2). Burette for fuel flow rate
3). Speed indicator-Digital
4). Digital Temperature Indicator-Multi point indicator with thermocouples.
5). Digital Voltmeter, Ammeter
Controls
The test rig is arranged for manual control of the engine with a kick
start arrangement for engine starting & manual throttle control.
Fuel measuring arrangement: Fuel Measuring Arrangement consists of fuel
tank, burette and suitable cock all mounted on a suitable frame work and
panel board and supplied with fuel piping from fuel tank to Engine.
Air intake measurement & heat carried away by exhaust gas
Consisting of an air tank mounted on an iron stand fitted with a
suitable orifice plate, manometer, Thermocouple for measuring the
exhaust gas temperature with pocket connection with instruments suitably
mounted on a panel board.
