An oil engine has a swept volume of 55 l and compression ratio of 12:1. The pressure and temperature of the charge in the cylinder at the beginning of the compression stroke are 0.1 MN/m² and 60 °C respectively. Assuming the compression curve follows the equation PV3=C. Determine the pressure and temperature at the end of compression. If the maximum temperature reached at the end of combustion, which may be assumed to take place at constant volume, is not exceed 1500°C estimate the mass of fuel required per cycle. Neglected all losses of energy and the increase in the mass of the charge due to the injected fuel. The calorific value of the fuel is 43.6Mj/kg. For the charge take R=0.29kJ/kgK and cv=0.72kJ/kgK. 7. (2.53MPA, 427°C, 1.09g)

For the statements in them, put T if they are true and F if they are false. a) ( ) An ideal gas expands freely from a volume V to a volume 2V. Then,this gas freely expands from 2V volume to 3V. In this case, it is not correct to state that theThe resulting change in entropy for these two expansions is equal to the change in entropy that would occur if the gas expanded freely from volume V to volume 3V.b) ( ) The Otto cycle is an idealization of engines in which expansion is so fast that it can be considered isothermal.c) ( ) No ideal engine has greater efficiency than one that has a cycle ofoperation between two isotherms and two adiabatic.d) ( ) A mixture of water and ice is in thermal equilibrium at a temperature of 273 K in an ideal calorimeter (adiabatic walls). A mass M of water at temperature T is added to the calorimeter, causing a part of the ice to melt until the thermal equilibrium is again reached at 273 K. Using c for heatspecific to water, we can state that the entropy…
