Diesel engines are currently the most widespread since their consumption, and the lower cost of fuel makes it a smart purchase in the long run, but how do these engines work?
Diesel engine characteristics.
-In the admission, only air introduced.
-It consists of an injection system, which introduces the pulverized fuel.
-The inflammation obtained by contact with the air.
What are the four times of a diesel engine?
1st Intake: The intake valve opened, and the cylinder begins the descent from its highest point (Upper Dead Point) to the lowest point (Lower Dead Point) filled with air.
2nd Compression: With the valves closed, the piston begins the ascent from the Lower Dead Point to the Upper Dead Point. Compression of the air that causes the temperature to rise to 600-650 ° C produced, being able to ignite the fuel.
3rd Combustion and Explosion: The fuel-injected through an injector that sprays the diesel into the chamber, causing it to swell immediately.
This process causes the force that generated to push the piston to the bottom dead center, producing gas expansion.
4th Exhaust: When the piston is in the lower dead center, the valve opened, and the gases generated by combustion expelled while the piston rises to the Upper Dead Point when it arrives the valves closed.
Types of Diesel
In Europe, three types of diesel currently marketed:
Diesel A:
-It is the highest quality diesel marketed.
-The price is the highest since it taxed by special taxes.
-Its use is as fuel.
Diesel B:
-Of the same quality as diesel A.
-It contains a red dye for identification.
-Its use is for agriculture and with motors whose purpose is not displacement (current generators).
– Cheaper because it taxed for fewer taxes on hydrocarbons.
Diesel C:
-It’s of worse quality.
-It has a lower price.
– Its usual use is in heating.
