Product description
The ratio e of the maximum and minimum cylinder volumes of a four-stroke engine is 9.5. The PV diagram of engine operation is shown in Figure 8.5. Outside air enters the engine at temperature t1=27 °C and pressure p1=105 Pa. At the moment of ignition of the combustible mixture, the pressure in the cylinder doubles. Answer the following questions and complete the tasks: 1. What processes occur with the gas between points 0-1, 2-3, 4-1 and 1-0? Processes 1-2 and 3-4 are adiabatic (y=1.4). 2. Determine the parameters p and T of the gas at points 1, 2, 3 and 4. 3. Calculate the efficiency of the heat engine cycle. 4. Assess the reality of the results obtained.
