One of the most reliable internal combustion engines out there.
It’s the diesel engine. In many industrial facilities, diesel
The engines are used as prime movers for the generation of
electricity and for emergency air compressors.
It is true that they are resistant, but one of the most important
advantages of these motors is the fact that they can be
started by manual start. In remote areas, diesel engines
He can be counted on to start from scratch.
Once a small diesel engine is started, it can be used for driving
a small electrical generator that can then be used to produce
power supply to drive other machines such as pumps,
compressors and lighting.
How does a diesel engine work?
First there must be combustion of fuel. as we have discussed
in our previous articles, the combustion or burning of fuel occurs
as long as there is enough heat, fuel and oxygen. When
conditions are right, combustion can be very rapid. Fast
combustion causes an explosion in an enclosed area. This is
due to the rapid accumulation of hot gases during the process.
In an internal combustion engine such as a diesel engine, this
rapid combustion, and the buildup of hot gas pressure is used to
push a piston out of the enclosed combustion space.
The piston is attached to a crankshaft through a connecting rod.
Due to this, the motor is able to convert the linear
movement of a piston to a rotating movement of a crankshaft.
The outward movement of the piston rotates the crankshaft. Nevertheless,
the momentum of the rotating crankshaft forces the piston backwards
back into the engine combustion space in a reciprocating motion
movement.
Once the piston is clear of the combustion space, the
pressure drops. The next stage of operation depends on the
engine design. These can be 2-stroke or 4-stroke
designs
Regardless of the type of design, the spent exhaust gas is
fresh air is first expelled and then re-introduced
the combustion chamber.
After this, the rotating crankshaft drives the piston to
compress the fresh air inside the combustion chamber. Tea
The piston acts as a reciprocating compressor at this stage.
The compression of the air causes the latter to become hot – hot
enough to ignite finely distributed fuel particles.
At this time, high-pressure fuel is injected. the tiny
the sprayed fuel particles form a mist inside the combustion chamber.
What do you think will happen when you have heat, fuel, and oxygen?
To shoot! Each minute particle of the fuel burns rapidly and a
the explosion occurs.
The cycle starts again, and the crankshaft rotates continuously,
the pistons move continuously and the engine runs.
How does the engine know when to spray fuel, let air in, compress
the air and expel the spent combustion product?
Well folks, start your engines.
