| One of the most reliable internal combustion | | | | convert the linear |
| engines around | | | | |
| | | | movement of a piston to a rotating movement |
| is the diesel engine. In many industrial | | | | of a crankshaft.The outward movement of the |
| installations, diesel | | | | piston turns the crankshaft. However, |
| | | | |
| engines are used as prime movers for the | | | | the momentum of the turning crankshaft |
| generation of | | | | forces the piston back |
| | | | |
| electricity and for emergency air | | | | again towards the engine combustion space in |
| compressors.It's true that they are rugged, | | | | a reciprocating |
| but one of the most important | | | | |
| | | | movement.Once the piston moves away from the |
| advantages of these engines is the fact that | | | | combustion space, the |
| they can be | | | | |
| | | | pressure drops. The next stage of operation |
| started by manual cranking. In remote areas, | | | | depends on the |
| diesel engines | | | | |
| | | | design of the engine. These can be either |
| can be counted upon for starting up from | | | | 2-stroke or 4-stroke |
| scratch.Once a small diesel engine is | | | | |
| started, it can be used to drive | | | | designs.Regardless of the type of design, |
| | | | the spent exhaust gas is |
| a small electrical generator that can then | | | | |
| be used to produce | | | | first driven out, and then new fresh air is |
| | | | drawn back into |
| electrical supply for driving other machines | | | | |
| like pumps, | | | | the combustion chamber.After this, the |
| | | | rotating crankshaft drives the piston to |
| compressors, and for lighting.How does a | | | | |
| diesel engine work?First there must be | | | | compress the fresh air inside the combustion |
| combustion of fuel. As we have discussed | | | | chamber. The |
| | | | |
| in our previous articles, combustion or | | | | piston acts as a reciprocating compressor at |
| burning of fuel occurs | | | | this stage.The compression of the air causes |
| | | | the latter to become hot - hot |
| whenever there is sufficient heat, fuel and | | | | |
| oxygen. When | | | | enough to ignite finely distributed fuel |
| | | | particles.At this moment, fuel is sprayed in |
| conditions are just right, combustion can be | | | | at high pressure. The tiny |
| very rapid. Rapid | | | | |
| | | | sprayed fuel particles form a mist inside |
| combustion causes an explosion in an | | | | the combustion chamber.What do think will |
| enclosed area. This is | | | | happen when you have heat, fuel and oxygen? |
| | | | |
| because of the rapid built-up of hot gases | | | | A fire! Each tiny particle of the fuel burns |
| during the process.In an internal combustion | | | | rapidly, and an |
| engine like a diesel engine, this | | | | |
| | | | explosion occurs.The cycle starts again, and |
| rapid combustion, and built-up of hot gas | | | | the crankshaft turns continuously, |
| pressure is used to | | | | |
| | | | the pistons move continuously, and the |
| push a piston away from the enclosed | | | | engine runs.How does the engine know when to |
| combustion space.The piston is attached to a | | | | spray fuel, let in air, compress |
| crankshaft through a connecting rod. | | | | |
| | | | the air, and exhaust the spent combustion |
| Because of this, the engine is able to | | | | product?Well folks, start your engines. |
