Divided chamber diesel engines use lower injection pressures compared to open chamber enginesbecause

(a) Pintle nozzles cannot withstand high injection pressures

(b) High air swirl does not require high injection pressures for atomization

(c) High injection pressures may cause over-penetration

(d) High injection pressure causes leakage of the fuel at the pintle
