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.

He is famous for the Lenoir cycle and the internal combustion engine.
The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.
The convection / subduction cycle.
In 1859 a Belgian engineer Jean Joseph Étienne Lenoirdeveloped the first internal combustion engine. It was a single-cylinder two-stroke engine which burnt a mixture of coal gas and air ignited by a spark-ignition system. He patented it in 1860.Nicolaus Otto invented a gas motor engine in 1876. He built the first practical four-stroke internal combustion engine, called the "Otto Cycle Engine", and built it into a motorcycle.Otto's patent was later revoked when it was contested by Beau de Rochas.
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.
The heat from the combustion reaction causes the pistons to move during the power stroke in the four-stroke engine cycle. This is when the high-pressure gases from the combustion expand, pushing the piston downward.
No combustion is not a part of water cycle. it s not involved.

diesel cycle is not called constant pressure cycle constant pressure cycle is Brayton cycle and there is hell of a difference with diesel cycle. you surely misunderstood the question man
combustion is the process of burning something. It adds a lot more carbon to the air.

Combustion releases carbon dioxide into the atmosphere when organic matter is burned. This disrupts the balance of carbon in the carbon cycle by increasing the amount of carbon dioxide in the atmosphere, contributing to global warming and climate change.
Using one cylinder for the 4 strokes of an internal combustion engine has certain limitations that using 2 cylinders in split-cycle engines overcome: Compression is more efficient in a cool cylinder. Combustion is initiated before top dead centre due to the limited combustion time available thus creating negative work against the rising piston. In the split cycle solution the compressor delivery valve prevents this. The two pistons can also be phased to better optimise combustion. A single chamber limits the expansion ratio to the compression ratio. The split-cycle facilitates a much larger expansion chamber for the increased thermal efficiency of the Atkinson cycle. However, discharging compressed air from the first to the second cylinder entails increased handling losses.
That graph is known as a pressure-volume loop. It is used in cardiology to assess cardiac function and to visualize the changes in pressure and volume within the heart during one cardiac cycle.
