सवाल

Which tests are done on engines?

Valve timing, load (performance) test, Morse test and heat balance on the engines available in the lab.

Are measuring instruments given for practice?

Yes. Each student practises on vernier, micrometer, slip gauges, sine bar and dial gauge.

Is this course based on the BTEUP syllabus?

Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
