Solidworks is not my ususal haunt (automotive) but we have recently looked into doing 3D modeling and am interested in first hand input on things to look for and to avoid. This is low volume, mostly for training purposes.
One of our staff stumbled across a do it your self 3D printer and that...
Over the last summer, I was sitting in the window seat of a Boeing 737, on the right side, just in front of the wing root, directly inline with the inlet of the turbofan. It was raining and there was quite a bit of water standing on the tarmac.
After pushback, the engines spooled up. I watched...
My wife an I just returned from a great vacation in Russia, particularly on a river cruise from Moscow to St. Petersburg.
Being a child of the US, and growing up with 120 VAC, it intrested me greatly about the use of 220, common in many parts of the world, just not in the US. I saw a cement...
What is the shelf life for a technical instructor? I have been doing this for close to 20 years now.
I am expected to stay on top of the technical industry, "cutting edge" on technology, then teach it to the technical users. I am recognized as an expert in my field and enjoy a bit of...
Many years ago, in the ‘60’s, I remember reading in one of the magazines published here in the US (Popular Mechanics), an article on injection molded rubber or soft plasticlike material tires. This past weekend, my wife and I were browsing through a yard sale and I came across that same...
Lets assume a marketing scenario:
A prominent auto manufacturer offers two models:
1) A vehicle which is SULEV (Super Ultra Low Emissions Vehicle) certified, for sale at a $1000 USD premium over the standard ULEV vehicle;
2) A vehicle which obtains 4 MPG better economy than the standard vehicle...
I normally run like crazy when someone asks me questions about a "new" engine, but when one of my directors asks me to evaluate a "new design" design, my knees shake. That happened this morning.
We have seen free pistons, opposed oscillating pistons, scotch yoke pistons, toroidal blocks, ball...
Has there been any more work on the Desmodromic engine? The Ducati and the JAP bike engines proved it would work. I once saw a lab engine with the desmo valve setup and it was eerie how easy the engine turned over when there was no valve friction on the camshaft.

Taking a queue from some of my other posts, and reading follow-ups, I would like to toss this in:
I have been working with an engineer, a young woman with an MSME, on a project. One of the deliverables was to make a presentation of findings and recommendations to a group of industry...
Here is a new twist!
I went on a job interview about 10 years (actually, to the job I now hold, but not with my hiring supervisor).
During the interview, my single interviewer asked me the usual questions interspersed with some questions it was very obvious were not a part of the regular...
To add fuel to my previous post, I would like to toss in modern grammer, or the lack of it. Do you judge the applicant by their command of the spoken language?
Take a look at this:
"Me and her gone to the store." Followed by "Me and him done this."
ARGGGHHH!
When I listen to what I think...
In my office, I am the only one to use Powerpoint for my lectures and presentations. I find them effective at communicating my message, ease of displaying photographs and charts, and shows that I am trying to keep at cutting edge. My colleagues tend to use overheads, slides, and non-stop...
I was recently on a job interview panel listening to job prospects. I was dismayed at the quality of candidates, (we were looking for a BSME minimum, with emphasis on engine combustion studies).
I was not especially displeased at their academic performance, however their presentation...
Although the term Large Spark Ignited Engine (LSI) is a bit confusing, the term actually applies to IC engines over approximately 35 bhp. In this case, it also applies to industrial engines, not over the road.
In preperaton for an engine fuel system certification, I recently reviewed the US EPA...
I was bench racing with a friend today and he told me of his new truck engine (4wd mud racing), something around 640 cid big block Chevy/Donovan running injected methanol.
He stated that the dyno showed a peak around 5500 rpm, tapered down, then re-peaked again around 7,000 rpm. I asked about...
