Question 2
An air standard two stroke Otto-cycle has stroke to bore ratio of 1.4 and volumetric efficiency 80%, then what will be the actual volume of air supplied to the engine in m3/min, if bore of the engine is 10 cm and engine running at a speed of 400 rpm.
Question 3
A diesel engine of bore 0.1 m and a stroke of 0.11 m has a compression ratio of 19 when running at 2000 rpm. The cycle has mean effective pressure of 1400 kPa and each cycle takes two revolutions. The engine power (in HP) will be, if the number of cylinders are 6
Question 4
For an otto cycle mean effective pressure is 15 bar. Bore diameter of the cyclinder is 0.2m and stroke length is 0.5 m. Heat supplied at constant volume is 30 kJ/cycle. Find cycle efficiency.
Question 5
A single cylinder four stroke engine operating at 80% of mechanical efficiency develops a brake power of 60 kW. The indicated power and the power lost due to friction respectively are:
