Otto and Diesel Processes
    
      - Cylinder model:
        
          - not included in ThermoDLR
 
          - built easily
            
              -  extend from PartialVolume
                contains HeatPort, Inlet, Outlet and most variables and
                equations 
              - add a mechanical flange
 
              - provide simple equations for volume, force and
                work at the flange
 
            
           
          - works in ThermoSimT testbed 
 
        
       
      - Otto cycle:
        
          - Inlet and Outlet switched off
 
          - validity of SimpleAir has
            to be extended to higher temperatures
            
              - SimpleAir(T_min=200,
                  T_max=2000)
 
            
           
        
       
      - Diesel cycle:
        
          - Inlet switched off
 
          - Outlet connected to pressure sensor
            
              - needed to control pressure for isobaric
