Engine Test Bed MODEL AM 244

Engine Test Bed MODEL AM 244

Sci-tech Engine Test Bed.

Item Description

SYSTEM DESCRIPTION
Sci-tech Engine Test Bed Model AM 244 is designed for students to conduct experiments and study the performance of different types of engines within the capacity of specified dynamometer. Any one or more of the engines specified and the Dynamometer coupled on a bedplate. The rig facilitates easy measurement of fuel consumption, air consumption, brake power and engine speed with data acquisition system (not applicable for Engines with speed regulation). Testing is carried out at different engine loads.

LIST OF EXPERIMENTS
 Measurement & Calculation of Volumetric efficiency.
 Measurement & calculation of specific fuel consumption
 Measurement & calculation of brake thermal efficiency
 Calculation Of Heat Balance sheet
 Brake Mean Effective Pressure and brake power on the basis of engine speed (for Variable Speed Engine only).
 Plotting of exhaust temperature versus Speed
 Determining air / fuel ratios
 Engine torque, brake power and brake thermal efficiency
 Specific fuel consumption
 Exhaust temperature
 Gas emissions and analysis
