engine diagrams
well today ive just been given a new uni assignment, basically i have to study two of the following mechanisms using an example of a real world use
and modelling and motion testing within solidworks.
gear train
crank slider
cam and follower
belt or chain drive
well to me, a perfect example of the last two in one product is an engine! so im wanting to model an engine in solidworks.
question is, does anyone have, or know of any good sources of well dimensioned diagrams that i can use as a basis for my model. i dont want to go have
stripping down my zetec to measure things!
preferably DOHC, with a few ancillaries so i can get decent belt systems and valve trains.
any help appreciated.

Why go so complex!!
Make up a small single piston belt driven model aeroplane engine.... that way you keep things small and can "imagine" the product in your
head without having to copy an existing complex design? (if you want a more complex belt system.... fit a small supercharger with belt tensioner
etc..)
Out of interest, what course are you doing? (and what uni)?
Im trying to decide what course to do next year, and have no idea... so confused!!

^ was thinking the same. why does it have to be an exact replica of a zetec for example?
it just needs to show how things work surely? why would it need to be exact?

don't write OT on a new thread title, you're creating the topic, everything you write is very much ON topic!

i was just thinking to make it easier for myself by just copying basic dimensions like valve angles, bores, etc. saves me alot of time fiddling and
adjusting to make it work. im not looking at doing an exact replica, sorry should of said earlier.
tegwin, im doing a course in CAD at LJMU, excellent uni and love the course! 100% coursework which suites me!

first thing to learn in engineering is the K.I.S.S principle
Keep It Simple, Stupid.
make you model really simple and easy, try and go to complex and you'll miss the obvious.
P.S. have a look on the How stuff works website for some examples
good luck my friend

I did a crank slider mechanism, did it very well and got a good mark
like people have said KISS and you can do a good job. Don't fancy the gear train myself but the other 3 could be very good pieces of work
fairly easily
Cam follower is a must to, well know as a straightforward study case
