A renowned automotive company has 1798 cc inline-4 engines working on Atkinson cycle (by late closing of intake valves during compression stroke). It has minimum compression ratio of 6.5:1 and expansion ratio of 13.5:1. If at part load conditions the pressure at the begining of compression stroke is 80 kPa and the temperature at the start of compression stroke is 60C. (Use gasoline with QHV value = 43000 kJ/kg, AF=19, Combustion Efficiency = 97% and EGR=20%). Do complete thermodynamic analysis

A manufacturer of snow blowers buys 4-horsepower, two cycle
engines in lots of 500 from a supplier. He then equips each of the
snow blowers produced by his plant with one of those engines. From
past experience he knows that the probability of any engine failing
is 0.002. In a shipment of 500 engines, what is the probability at
least one is defective?

A gas refrigeration cycle with a pressure ratio of 4 uses helium
as the working fluid. The temperature of the helium is -6°C at the
compressor inlet and 50°C at the turbine inlet. Assume isentropic
efficiencies of 88 percent for both the turbine and the
compressor.
(Given: The properties of helium are cp=
5.1926 kJ/kg·K and k = 1.667.)
FIND:
a. The minimum temperature of the cycle.
b. The coefficient of performance.
c. the mass flow rate of the helium.
