This sounds like a homework question and I don't know what your teacher wants. But here goes.
And a bunch more that I have forgotten.
The term "hemi engine" refers to an engine with a hemispherical combustion chamber. The word "hemi" is short for hemispherical, and it describes the shape of the combustion chamber in the cylinder head of the engine. This design is known for its efficiency in allowing air and fuel to flow in and out of the chamber, leading to improved combustion.
Diesel Engine combustion chamber types : Swirl port combustion chamber type and Preignition port combustion chamber type.

The radius of the fibular device affects the logic of sodium chloride to h2o by the decay of subzero temperatures where the combustion chamber deteriorates.
A combustion chamber is where combustion occurs in a controlled fashion. Because the basic idea of a rocket is burning fuels and directing them in the opposite direction to that of travel, a controlled burning - as happens in the combustion chamber - is exactly what a rocket needs to work.

From the combustion of air and fuel in the combustion chamber.
boiler efficiency is how much water is converting to steam.
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
Hemispherical combustion chamber
The fuel/air mixture passes through the intake valve to get into the combustion chamber. After combustion, the spent gasses travel out of the combustion chamber through the exhaust valve.
The area is called the combustion chamber.
