OTTO CYCLE
What is OTTO CYCLE?
Thermodynamic cycle that describes the functioning of a spark ignition piston engine.
What is Intake Valve in Spanish?
Valvula de admision
Describe the Compression process
The piston rises and the intake valve closes. Because the exhaust is also closed, the piston compresses the air and fuel mixture.
What is Thermodynamic cycle?
Process or set of processes that leave the system back in the original state it had before it was performed.
What is Exhaust Valve in Spanish?
Valvula de escape
What are the 4 processes of combustion?
Admission, Compression, Explosion and Escape
What is the ignition order?
It is the sequence that follows the order of the cylinders when performing their combustion time in a multicylinder internal combustion engine.
What is Camshaft in Spanish?
Árbol de levas
Describe the "Admission" process
The piston descends, the intake valve is opened and this allows the air and gasoline mixture to enter the cylinder. Meanwhile, the exhaust valve is closed.
Explosion orden in the 4 times engine
1-3-4-2
1-2-4-3
1-3-2-4
What is Crankshaft in Spanish?
Cigüeñal
Describe the "Explosion" process.
The piston reaches the maximum of its travel. The spark plug then produces an electric spark that gives way to the explosion, so the piston is driven downwards.
What is Lower deadlock (PMI)?
Closest point to the crankshaft reaching the piston in its alternative movement within the cylinder.
What is Engine block in Spanish?
Bloque de motor
Describe the Escape process
The piston rises again, but the exhaust valve is no longer closed: it opens to allow the burnt gases to escape.
