Automotive 4 Stroke Petrol Engine – Asynchronous Motor Start Model AM 218 SYSTEM FEATURES
Item Description
Sci-tech Automotive 4 Stroke Asynchronous Start Engine Test System Model AM 218 is designed for students to conduct experiments and study the performance of the engine. The engine uses asynchronous motor as brake system required to carry out experiments. 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.
