In a engine, well 99.9% of them the piston is conected to a crank via a conrod, as nothing changes during the strokes of the piston and the cylinder bores dont change.
The swept volume of the stroke is always constant.

What is constant volume?
The constant Volume process, also known as Isovolumetric, is where the volume is constant and does not change. In a P, V, Diagram this should be where volume is constant where Pressure is increased. The work done (area under the curve) would be = to 0 in this case.
What is it called when the volume of a gas increases and the pressure decreases?
Charles' Law says that as pressure on a gas decreases, its volume increases. Charles' Law is an example of an inverse relationship.t It is not Charle's law It is Boyle's law Charles law states at constant volume, pressure is proportional to kelvin temperature And at constant pressure volume is proportional to kelvin temperature But Boyle's law states that at constant temperature pressure is inversely related to volume
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
When the volume is constant how do the masses of 2 objects differ?
When volume is constant, the masses of two objects are in direct proportion to their densities.
What is the relationship between volume temperature and pressure that is useful for designing things with fixed-volume pistons?
You can use the ideal gas law: PV=RTn, where: P is the pressure V is the volume R is the proportionality constant, the so-called "gas constant" T is the absolute temperature n is the number of moles
What is the difference between four stroke petrol engine and that of diesel engine?
Petrol engines are sometimes also called constant volume engines. They suck in a combustible mixture of fuel and air, compress it and then ignite it with a spark plug. Combustion is so fast that (most of it) takes place while the volume of the compression chamber(in the cylinder, between piston and cylinder head) stays the same. Then, as the piston moves away from Top Dead Center (TDC) combustion is (mostly) done and the pressure begins to drop. Diesel engines are also called constant pressure engines. They take in air, compress it to the point where the temperature alone will ignite the fuel, and then they inject the fuel. And fuel keeps being injected and burned as the piston moves away from TDC, keeping the pressure, kinda-sorta constant through the combustion phase.
Why diesel engines called constant volume engines?
They aren't.Gasoline engines are (sort-of) constant volume engines while Diesel engines are (sort of) constant pressure engines.In a gas engine, the combustion process is so fast compared to the travel rate of the piston that it all happens in the same volume, before the piston has had much time to move away.In a Diesel engine combustion is so much slower that the piston will actually have time to move away while fuel is still being burnt.As the volume of the combustion chamber increases during burn as the piston moves away, the pressure will remain pretty much the same throughout the burn.
Differences between petrol and diesel engines?
sic difference between Petrol and Diesel engines that the difference of fuel and their mixture..in diesel we only compresses the Air and sprays Diesel but in Petrol Engines we compresses both the air and Petrol together and gets burnt with the the help of spark given by the Spark plug. I must add this, also the thermodynamic cycle is so different in diesel engines rather than petroleum engines. You can fined more in Reed's series volume 12
What is the clearance volume of petrol engine?
The volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
What is the volume of a petrol tank?
Petrol tanks are NOT a standard size.
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
Why does a petrol pump have a volume measurer inside it?
A petrol or gas pump has a volume measurement device inside it to measure the expansion of the gases that come from the petrol. As the gases expand, they can actually cause explosions.
How may liquids be described in terms of shapes and volume?
A solid has a constant volume and a determinate shape.A liquid has a constant volume but an indeterminate shape.A gas has an indeterminate volume and an indeterminate shape.liquids have a constant volume at a constant temperature, and take the shape of their container.

What is the the volume of a gallon of petrol?
1 gallon.
When does raising the temperature of gas increase its pressure?
Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
Why Do Gasses Have Two Specific Heats?
One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.
