The temperature and pressure values at the beginning of compression in a V 6 gasoline engine with a three - liter stroke volume running at

The temperature and pressure values at the beginning of compression in a V6 gasoline engine with a three-liter stroke volume running at 2400 rpm according to the ideal cycle at full throttle are 60\deg C and 98 kPa. The compression ratio of the engine is 9.5:1, the H/Y ratio is 15.5:1 and the fuel used is gasoline. Assuming that the combustion efficiency is 96% and the mechanical efficiency is 84%; Answer the following questions based on the information given. (Note: There is no residual gas in the cylinder at the end of the cycle.)
a) Show the cycle steps by drawing p-v and T-s graphs. (5p)
b) Calculate the temperature (\deg C) and pressure values (kPa) at each point of the cycle. (35p)
c) Find the specific work (kJ/kg) produced during the expansion time. (5p)
d) Calculate the amount of heat energy (kJ/kg) that enters the cycle during combustion. (5p)
d) Find the net work (kJ/kg) produced during the cycle. (5p)
e) Calculate the thermal efficiency (%) of the cycle. (5p)
f) Calculate the indicated engine power (kW).(5p)
g) Calculate the effective engine power (kW).(5p)
g) Find the power (kW) spent on friction. (5p)
h) Calculate the torque (N.m) for the given engine speed. (5p)
i) Calculate the average effective pressure (kPa).(5p)
i) Calculate the effective specific fuel consumption (g/kW.h).(5p)
j) Calculate the volumetric efficiency (%).(Take the density of air as 1.181 kg/m3.)(5p)
k) Calculate the power per liter of stroke volume (kW/lt).(5p)
