Single Cylinder Four Stroke Water Cooled Slow Speed Diesel Engine Test Rig With Mechanical Brake (Rope Brake) Loading.
Introduction
The test rig is designed to provide self-contained facility for teaching Compression Ignition engine principles. The equipment is instrumented so that the following experiments could be performed.
1). Bhp Measurement
2). Brake Thermal Efficiency
3). Fuel Consumption Measuement
4). Air Intake Measurement
5). Measurement Of Heat Rejected To Water Jacket

The engine test rig facilitate to evaluate the following
1). Heat Balance Sheet.
2). BHP Measurement from no load to full load.

Description
Two/Three main components from main parts of the test rig. Welded steel base plate, complete with A.C. Alternator/Mechanical Brake/ Hydraulic Dynamometer/ Eddy Current Dynamometer, Drive shaft with safe guard and anti vibration mounting. Resistance loading (Resistance bank) with selector switches to load the engine from no load to full load (as applicable) 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 Mechanical Brake capable of absorbing a maximum load of 10HP at a speed of 1500RPM.
2). The Dynamometer used is a Hydraulic Dynamometer capable of absorbing a maximum load of 10 HP at a speed of 1500 RPM.
3). The loading device used is and AC alternator of matching capacity to load the engine up to 10 HP at 1500 RPM along with Resistance loading arrangement with selector switches.
4). The loading device used is and Eddy Current Dynamometer of matching capacity to load the engine up to 10 Hp at 1500 RPM

Instrumentation
1). The following instrumentation is provided. 'U' tube manometer for air flow rate
2). Burette for fuel flow rate
3). Digital Temperature Indicator- Multi point indicator with thermocouples.
4). Digital Voltmeter, Ammeter

Controls
The test rig is arranged for manual control with Hand cranking start arrangement for engine starting.
