The Single Cylinder Petrol Engine Test Rig, manufactured by Atto Labware, is a complete training system designed for the study and performance evaluation of internal combustion engines. It allows students to conduct experiments on a single-cylinder, four-stroke petrol engine under various load conditions. The system is mounted on a robust mobile workstation with all necessary instrumentation for accurate measurement and analysis, making it ideal for technical institutes, universities, and automotive labs.
Educational Objectives
Students will be able to:
-
Understand the construction and working principles of a four-stroke petrol engine.
-
Measure engine performance parameters such as torque, speed, power, and efficiency.
-
Conduct heat balance tests and determine fuel consumption.
-
Analyze brake power, indicated power, and mechanical efficiency.
-
Study the effects of load, speed, and air-fuel ratio on engine performance.
Performance Measurement
-
Measurement of torque and brake power using a dynamometer.
-
Recording of fuel consumption rate and air flow.
-
Calculation of thermal efficiency and specific fuel consumption (SFC).
-
Plotting performance curves such as brake power vs. fuel consumption.
-
Comparison of theoretical and experimental results.
