Yes, it happens. Perhaps, you are confused by Boyle 's law that pressure and volume are inversely related to each other. But Boyle's law is true only when temperature and QUANTITY OF GAS are kept constant.As in this case, the air is filled in to the tube so Quantity of gas is increased so Boyle' law is not applicable.
As volume changes so does pressure. During the compression cycle of an engine, the volume is decreasing causing the pressure to increase. This happens so rapidly that I do not believe that temperature stays constant. For this to actually be following Boyle's law the temp is supposed to remain constant.
From Wikipedia, the free encyclopedia Dual Combustion Cycle (also known as the limited pressure or mixed cycle, Seiliger cycle or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle. Heat is added partly at constant volume and partly at constant pressure, the advantage of which is that more time is available for the fuel to completely combust. Because of lagging characteristics of fuel this cycle is invariably used for diesel and hot spot ignition engines. The dual cycle consists of following operations: # Adiabatic compression # Addition of heat at constant volume. # Addition of heat at constant pressure. # Adiabatic expansion. # Rejection of heat at constant volume.
An increase in heat or pressure could cause further metamorphism.
Evaporation is the process in the water cycle caused by an increase in temperature.
Heat and pressure help in changing the state of matter. Water exists in different state in water cycle.
It really is not constant, but to solve problems that want you to only use Boyle's Law and not the combined gas law it is important that you assume that volume is constant. The change in volume is not really that great.
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.

The heat addition and rejection processes in otto cycle are of constant volume, whereas in brayton cycle, they are of constant pressure.
-increase the temperature of the super heated steam -lowering the condensing pressure -increasing the boiler pressure (Reheating, regeneration...)
Do you mean pressure control and volume control?? instead of cycle? IF YES, Pressure control is used when you want a specific peak airway pressure aka PIP it is also used the mode of choice in the NICU and PICU Volume control is used when you want to reach a desired tidal volume. These are also dependent on the patients lung characteristics. It is also important to remember that in either mode it is possible to manipulate the other variables such as inspiratory flow, rate, rise time and I:E (to name a few) to obtain or control volume or pressure.

ratio of maximum to minimum pressure only case of constant volume heat addition in engine cycle
Cardiac Cycle
the difference is the heat addition type In Otto Cycle the heat addition is Isochoric ((constant volume)) In Diesel Cycle the heat addition is Isobaric ((constant pressure))
in otto cycle the burning of fuel is instantaneously therefore a very small voulme is required for burning of fule
the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.
