Atwo-liter, four-cylinder, open-chamber si engine operates at 3500 rpm using stoichiometric gasoline. at this speed, volumetric efficiency is 93%, combustion efficiency is 98%, indicated thermal efficiency is 47%, and mechanical efficiency is 86% calculate:
(a) brake power. [kw]
(b) bmep. [kpa]
(c) amount of unburned fuel exhausted from the engine. [kg/hr]
(d) bsfc. [gm/kw-hr]

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
