Number the statements listed below in the order that they would occur in engine operation. then, label these stages as intake, compression, power, or exhaust.
a. the fuel mixture is ignited by the spark plug, and the resulting explosion forces the piston down in the cylinder.
b. the piston rises and compresses the fuel mixture in the combustion chamber.
c. the exhaust gases left over from the combustion are released from the cylinder. d. a mixture of air and fuel is drawn into the cylinder

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
