APA is becoming more often used in the engineering classes as a citation style.
Texas Tech has a great guide for the APA Style guide located here.
The biggest thing to remember about citations is that they are based on a pattern. The second biggest thing is that the citation generators, either through the University Libraries or other places will not always give you the correct information. So you should follow the pattern of the citation style and check the ones you copy and paste from the databases against the examples on our pages or within the APA style guide.

References. In the text, cite publications by listing the last names of the authors and the year, which is called the author-date method of citation; e.g., (Duan et al. 1990; Frater and Packer 1992a). Prepare an appendix listing all references alphabetically by last name of the first author. For anonymous reports and standards, alphabetize by the issuing institution. Double-space the reference section.
Make sure reference information in the APPENDIX. REFERENCES is complete and accurate ... including as necessary and in the following order:
Citations specifically published from ASCE journals, will look like this:
From the ASME's Guidelines
Text Citation. Within the text, references should be cited in numerical order according to their order of appearance. The numbered reference citation should be enclosed in brackets.
Example: It was shown by Prusa  that the width of the plume decreases under these conditions.
In the case of two citations, the numbers should be separated by a comma [1,2]. In the case of more than two references, the numbers should be separated by a dash [5-7].
List of References. References to original sources for cited material should be listed together at the end of the paper; footnotes should not be used for this purpose. References should be arranged in numerical order according to the sequence of citations within the text. Each reference should include the last name of each author followed by his initials.
(1) Reference to journal articles and papers in serial publications should include:
(2) Reference to textbooks and monographs should include:
(3) Reference to individual conference papers, papers in compiled conference proceedings, or any other collection of works by numerous authors should include:
(4) Reference to theses and technical reports should include:
