Code: TIE0009
Four Stroke Four Cylinder Diesel Engine Test Rig.
Introduction
The test rig is designed to provide self-contained facility for teaching
Internal Combustion (Compression Ignition) engine principles. The
equipment is instrumented so that the following experiments could be
performed.
1). Bhp Measurement
2). Ihp Measurement
3). Fhp Measurement
4). Fuel Consumption Measuement
5). Air Intake Measurement
6). Measurement Of Heat Rejected To Water Jacket
7). Heat Balance Test
The engine test rig facilitate to evaluate the following
1). Performance at various throttle position
2). Heat Balance Sheet.
3). Performance (BHP Measurement) from no load to full load.
Description
Two main components from main parts of the test rig. Welded steel base
plate, complete with Dynamometer, drive shaft with safety guard, engine
starting battery of 12V capacity and cooling water arrangement Panel
board positioned over the base plate consisting of fuel system with flow
measurement by burette, air flow measurement system, temperature and
speed indicator.
Dynamometer (as applicable)
1). The Dynamometer used is a Hydraulic Dynamometer capable of absorbing a maximum load of 10 HP at a speed of 1500 RPM
2). The Loading device used is an AC Alternator of
matching capacity to load the engine up to 10 HP at 1500 RPM along with
Resisistance loading arrangement for alternator.
3). The loading device used is an Eddy Current Dynamometer of matching capacity to load the engine up to 10 HP at 1500 RPM.
Instrumentation (as applicable)
1). The following instrumentation is provided.
2). Engine oil Pressure gauge
3). Engine charging circuit ammeter
4). 'U' tube manometer for air flow rate
5). Burette for fuel flow rate
6). Digital Temperature Indicator- Multi point indicator with thermocouples.
7). Digital Voltmeter, Ammeter
Engine starting
The test rig incorporates a 12 V DC electrical system designed for use
with typical engine self starter system. The battery is included in the
scope of supply.
Controls
The test rig is arranged for manual control with Ignition switch for
engine starting manual throttle control, manual control for hydraulic
dynamometer loading and a manual operated clutch actuator arrangement to
drive the engine with load or without load (For No Load testing)
Fuel measuring arrangement
Fuel Measuring Arrangement consists of fuel tank, burette and suitable
cock all mounted on a suitable framework 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. Heat carried away by cooling water
Consists of suitable inlet and outlet piping with flow control valve.
Rota meter to measure the rate of flow of cooling water and Thermocouple
with pocket connections for measuring inlet and outlet water
temperature.
Engine
Four Cylinder Four Stroke Water Cooled Vertical Diesel Engine to develop 10 HP @ 1500 RPM (Make: Hindustan Stride/Isuzu)
Services
Electrical supply of 230V, Single Phase, 50Hz AC & external cooling water supply.
