why in dual cycle heat addition at constant volume process is first then after heat addition at constant pressure process is done?
A dual cycle is a thermodynamic cycle that combines elements of both the Otto and Diesel cycles. It is a theoretical model for an internal combustion engine that allows for greater efficiency and power output compared to a single cycle.
The heat addition process in a dual cycle occurs when fuel is injected into the combustion chamber and ignited, causing a rapid increase in temperature and pressure. This process is similar to the Otto cycle, but with the addition of a constant pressure heat addition phase, as seen in the Diesel cycle.
The addition of the constant pressure heat addition process in a dual cycle allows for more heat to be added to the working fluid, resulting in a higher efficiency compared to a single cycle. This is because the heat addition process occurs at a lower temperature and pressure, reducing the amount of wasted energy.
The heat addition process in a dual cycle can be affected by various factors, such as the fuel used, the compression ratio, and the speed of the engine. These factors can impact the temperature and pressure at which the heat addition occurs, thus affecting the efficiency and power output of the engine.
In a dual cycle, the heat addition process differs from an ideal Otto or Diesel cycle in that it includes both a constant volume and a constant pressure heat addition phase. This allows for a more efficient use of fuel and a higher power output, making it a more ideal model for internal combustion engines.
