Accepted Answer

Option B: Injector cooling water tank and piston cooling water drain tank.. Injector and piston cooling systems are prone to oil contamination due to their proximity to combustion and lubrication spaces. Drain tanks for these systems are specifically designed with oil separation capabilities, such as skimming or settling, to prevent oil from fouling the cooling water and heat exchangers.
