Definition of charging, compression, work and exhaust
 |
| entrance: the entry of new gas into the cylinder through the intake valve
Temperatur
» 20°C
Vakum
0,1 ÷ 0,6 bar
|
 |
| Compression: a new gas compression with reduce space, so the pressure & temperature rises, intake valves & exhaust valve close.
Final Presure of compression =
Otto = 1 ÷ 1,5
Mpa ( 10 ÷ 15 bar )
Diesel = 1,5 ÷ 4 Mpa ( 15 + 40 bar )
Final Temperature of Compression
Otto = 300 ÷ 6000C
Diesel
= 700 ÷ 9000C
|
 |
Work: The pressure of combustion push the piston down, the intake valve and exhaust valve close.
Maximum Temperature of Ignition :
Otto = 2000 ÷ 25000C
Diesel =
2000 ÷ 25000C
Maximum Presure of Ignition :
Otto = 3 ÷ 6 Mpa ( 30 ÷ 60 bar )
Diesel = 4 ÷ 12 Mpa
(40 ÷ 120 bar |
 |
| Exhaust: the output of the ex gas in the cylinder, through the exhaust valve
Temperature of exhaust Gas (full load):
Otto = 600 ÷ 10000C
Diesel = 500 ÷ 6000C
