Hi,
I've just taken peak pressures on a 16 cylinder 10000 hp diesel engine used to provide electrcal power for a drilling ship. The average peak pressure in each cylinder was 177 bar.
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
In terms of engines, an external combustion engine such as a steam engine burns fuel outside of the pressure cylinder used to drive the piston. An internal combustion engine such as a petrol or diesel engine burns the fuel inside the pressure cylinder used to drive the piston.
For an engine to work efficiently, the pressure inside the cylinder must be equal to the pressure outside to allow for proper combustion and expansion of gases. This ensures that the engine can generate the necessary power to move and operate effectively. Any difference in pressure between the inside and outside of the cylinder can lead to issues such as poor performance, engine knock, or even damage to the engine.
Cylinder pressure refers to the pressure of the fuel-air mixture inside the combustion chamber of an engine. It is a critical parameter that influences engine performance and efficiency, with higher cylinder pressure generally leading to more power output. Monitoring and optimizing cylinder pressure is key to maintaining engine health and performance.
There are two types of charging processes- 1.naturally charging:charging at the atmospheric pressure,just by the piston movement,inducing the air inside the cylinder. 2.supercharging:charging the air under pressure.
both petrol and diesel are i.c. engines, being that the energy is created inside the cylinder (internally) by burning the fuel therein, as compared to say steam engine which creates energy source (pressurised steam) externally in the boiler prior to delivery to the cylinder(s)
yes because if the valves covers are leaking what is there to contain the pressure inside the cylinder
That is part of the oil pump inside the engine.That is part of the oil pump inside the engine.

Ultra-low sulfur diesel (ULSD) is a standard for defining diesel fuel with An engine running on diesel compresses the air inside the cylinder to high pressures refrigeration units on vans/trucks which contain perishable items such as food
Motoring curve is Cylinder pressure Vs crank angle curve, which is observed when no firing occurs into the cylinder that means the pressure which build inside the cylinder is basically due to the compression of the fresh air charge going into the cylinder.
The cylinder, is the body of the engine that has been bored out in order to place a piston inside of it. The piston rides inside the cylinder.
