Item Description

Features

• Designed for comprehensive analysis of performance of different automobile engines.
• Digital Instruments for measurement of parameters like fuel consumption, air flow, temperature and RPM etc.
• Demonstration of performance of Petrol Engines at different throttle settings & Loads.
• Optional High Speed Data Acquisition system for performance monitoring.

Sci-tech Automotive 4 Stroke 3 or 4 Cylinder Petrol Engine Test Bed Model AM 225B is designed to felicitate testing of different automobile petrol engines. The test bed is complete with eddy current dynamometer and measuring instruments for measuring key engine parameters required for performance analysis of an engine. The test bed can be used for testing of petrol engines of passenger cars, rated up to 80 kW.

The test bed consists of a water cooled eddy current dynamometer fixed on a heavy-duty steel frame. The test bed is designed in such a way that the engine to be tested can be quickly coupled to the dynamometer with minimum effort. The test bed is equipped with dynamometer control panel with necessary safety instruments. The Engines can be used for performance tests for different loads and speeds under various throttle opening conditions. The eddy current dynamometer provides a variable load on the engine, allowing the characteristic power and torque curves to be reproduced in the laboratory. The system comes complete with extensive instrumentation, including rpm measurement, torque (from which power can be calculated), plus various temperatures, Fuel Consumption, Air Consumption.

Different optional accessories are available to integrate with the Engine Test Bed for comprehensive engine performance analysis. These include the exhaust gas calorimeter (For Heat Balance Sheet), advance Data Acquisition System & P-V Diagram module for computerized testing.
