In which type of combustion chamber hole-type nozzle are preferred?(a)

1.	In which type of combustion chamber hole-type nozzle are preferred?(a) Pre-combustion(b) Open type(c) Both pre-combustion and self-cleaning(d) Self-cleaningI got this question at a job interview.I need to ask this question from Diesel Engine Fuel Supply System in portion Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» Correct option is (b) Open type The best I can explain: The nozzle USED may be CLASSIFIED broadly into the HOLE type and the pintle type wherein the hole type nozzles are generally used in engines with the open type COMBUSTION CHAMBER and the pintle type nozzle has an extension.
