REPORT TITLE: The Usage of Mechanical Systems in Towns and Cities: A Problem-Solution Approach

1. THE SOURCE

How long is your source? 8pages.How did you find the source?:I typed in howstuffworks engine into the Google search

engine. This article was the first on the list.

Write a complete APA reference for your source:

Brain, M. (n.d.). How car engines work.

Retrieved from http://www.howstuffworks.com/engine.htm

2. SUMMARY OF THE SOURCEIn about100 words, summarize the main points of your source.

The articles main objective is to discuss, with sufficient detail, the internal combustion

engine, opting to use a conventional car engine for demonstrative purposes. It commences its

premises by explicitly defining what an internal combustion engine is, and making clear-cutits distinction from its counterpart, the external combustion engine. It then proceeds to

illustrate the mechanism by which such an engine is driven, which manifests in what isknown as the four-stroke combustion cycle (also known as Ottos cycle). Afterwards, it

subdivides internal combustion engines as inline, flat and V-shaped engines based on their

cylinder configuration, while briefly discussing how each configuration fits a specificapplication. With quite sufficient detail then, the article proceeds to discuss the main parts of

an engine and the major systems of which its made up, with such a discussion beyond the

scope of this summary. The article then lists the most frequent problems an internalcombustion engine can run into and tries to provide solutions to the foregoing problems. The

article concludes its deliberations by answering some of the most frequent questions about

internal combustion engines.

3. EVALUATION:In about 100 words, explain why you chose this source for your report.Relevance: connect relevant parts of the source with your outline.Article: what level is it? How up-to-date is the information?Publication / website / author: are they reputable, unbiased and knowledgeable?

The article is quite relevant to my report since an entire section of it is dedicated to engines.The language level of the article is quite mild and the article seems up to date, though such a

requirement is redundant since internal combustion engines didnt change drastically since

their inception. The website is quite reliable and its authority in its niche is quite established.
