NOZZLE AND METHOD OF MAKING THE SAME
Document Type and Number:
Japanese Patent JP2017137869
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of making efficient fuel injectors that increase fuel efficiency.SOLUTION: A method includes the steps of: (a) providing a first material that is capable of undergoing multiphoton reaction; (b) forming a first microstructured pattern in the first material using a multiphoton process; (c) replicating the first microstructured pattern in a second material to make a first mold that includes a second microstructured pattern; (d) replicating the second microstructured pattern in a third material to make a second mold that includes a third microstructured pattern; (e) planarizing the third microstructured pattern of the second mold with a layer of a fourth material, where the top of each of a plurality of microstructures forming the third microstructured pattern is exposed; and (f) removing the third material resulting in a nozzle that includes a plurality of holes in the fourth material, where the holes correspond to the plurality of microstructures forming the third microstructured pattern.SELECTED DRAWING: Figure 2
