Computerized Single Cylinder Two Stroke Petrol Engine Test Rig with PFI Open ECU and EGR

Description

The engine is mounted on a sturdy base frame. The base frame is fabricated with mild steel “C” channel. The engine and the dynamometer are coupled using standard tyre coupling. The air tank is fitted with a differential pressure sensor for measuring the actual volume of air drawn into the cylinder. The thermocouple and necessary signal conditioner for the measurement of temperature at various points in the calorimeter are suitably provided. A liquid level sensor is used to measure the fuel flow consumption of the engine. A rotameter is used to measure the water flow of the engine and exhaust gas calorimeter. The load of the engine is measured using a load cell. The panel is fabricated with suitable SWG CR sheet and as per IS standard; the front portion of the panel is provided with provision for mounting computer, printer, UPS and all instrumentations and signal conditioner related components. Power and control wiring are suitably marked using ferrules for easy troubleshooting. The panel is finished with powder coating.

Experiments you can perform

1. Performance test at varying loads: brake power, BSFC and brake thermal efficiency
2. Determine mechanical and volumetric efficiency
3. Heat balance sheet using the exhaust gas calorimeter
4. Combustion analysis: P-θ and P-V diagrams, heat release rate and mass fraction burnt
5. Determine start of combustion, combustion duration and gross IMEP
6. Effect of injection and spark timing on performance and combustion
7. Effect of EGR on performance and combustion
