Divided chamber diesel engines use lower injection pressures compared to open chamber engines because
Option (A)
Pintle nozzles cannot withstand high injection pressure
Option (B)
High air swirl does not require high injection pressures for atomization
High injection pressure may cause over-penetration
High injection pressure causes leakage of the fuel at the pintle
Correct Option:
Question Solution:
Divided combustion chamber has very strong swirl with speed, is generated. The strong swirl enable single hole nozzle generally pintle type.
