1.	What is the opening pressure range in MPa of a hole-type nozzle?(a) 5-7(b) 10-17(c) 17-34(d) 37-54I have been asked this question in an international level competition.My doubt stems from Diesel Engine Fuel Supply System in section Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The CORRECT option is (c) 17-34 The best I can EXPLAIN: The OPENING pressure of the hole-type nozzle varies from 17 to 34MPa. DUE to which the hole type fuel injector has good fuel atomization and this happens in a proper QUANTITY. And the fuel is injected in the cylinder properly.
