Question

An engine working on Otto cycle has
temperature and pressure at the beginning
of compression as 1.4 bar & 25 Degree
Celsius. If the pressure at the end of
compression is 10 bar, find air standard
efficiency of the cycle.
O a. 40 %
O b. 33 %
O C. 30 %

Answer 1

Answer:

The power produced by the Otto cycle is an energy developed per unit of time. The Otto engines are called four-stroke engines. The intake stroke and compression stroke require one rotation of the engine crankshaft. ... At an engine speed of 3000 RPM there are 1500 work-strokes/minute or 25 work-strokes/second.
