A gas engine bore 250 mm, stroke 460 mm has a compression ratio of 4(1/2). At the end of suction the pressure is 90KN/m².
Compression equation PV¹.³⁵= C. Expansion equation PV¹.³= C.
If the pressure is trebled during the constant volume explosion, find the mean effective pressure and the I.P developed if the engine makes 85 explosion/minute.
